Do-It-Yourself maintenance is always the cheaper route to a repair, as you aren’t paying for a pro’s labor rate. The current average labor rate for an independent shop is around $80 per hour according to AAA, while dealerships average a little over $100 per hour. If the pro shop install takes two hours, you’re out $200 in just labor, on top of the cost of parts. If it takes you two hours to do it yourself, the labor rate is $0, so it’s only the cost of parts. Keep in mind that direct-fit cats designed specifically for your vehicle will install more smoothly than universal fit. It may be worth it to spring for the direct-fit and save your mechanic a half hour of work.

However, there are huge benefits to having a professional under your hood. It’s like having at trained chef making your meals or a skilled tailor making your clothes; an expert on the task can make a dramatic difference. There’s a risk involved when you’re just going by OBD-II codes and don’t know how to interpret them correctly.

“A professional can see other things going wrong with the system,” said Rakowski. “Just because they got the code for it, that doesn’t mean the catalytic converter is bad. It could be an exhaust leak, it could be oxygen sensors, it could be anything that has to do with feeding air or fuel into the system, and it could set that code.”

Rakowski has heard plenty of customers say they tried to fix the symptoms themselves. “They put in a cat for 350, 400 bucks, low and behold, a month later the code trips again.” Even if you install a brand new high quality catalytic converter, it will suffer the same problem and quickly fail unless the real culprit is found. The lesson is to properly diagnose the correct issue, not just fix the symptoms of failure.

Have you recently had a catalytic converter replaced? Did you go DIY or let the pros handle it? Let us know in the comments below.

Theft of catalytic converter

catalytic converter are also at risk of theft,

Pipe cutters are often use to quietly remove the catalytic converter

but other tools such as a portable reciprocating saw can damage other components of the car of catalytic converter,

such as the alternator, wiring or fuel lines, with potentially dangerous consequences.

Rising metal prices in the U.S.

during the 2000s commodities boom led to a significant increase in converter theft.

A catalytic converter can cost more than $1,000 to replace, more if the vehicle is damage during the theft.

From 2019–2020, thieves in the United Kingdom were targeting older-model hybrid cars which have more precious metals than newer vehicles

—sometimes worth more than the value of the car—leading to scarcity and long delays in replacing them.

Diagnostics of catalytic converter

Various jurisdictions now require on-board diagnostics to monitor the function and condition of the emissions-control system, including the catalytic converter.

Vehicles equipped with OBD-II diagnostic systems are designe to alert the driver to a misfire condition

by means of illuminating the “check engine” light on the dashboard

, or flashing it if the current misfire conditions are severe enough to potentially damage the catalytic converter.

diagnostic systems take several forms

Temperature sensors are use for two purposes.

Modern catalytic-converter designs are not as susceptible to temperature damage and can withstand sustained temperatures of 900 °C (1,650 °F).

Temperature sensors are also use to monitor catalyst functioning:

usually two sensors will  fit, with one before the catalyst and one after to monitor the temperature rise over the catalytic-converter core.

The oxygen sensor is the basis of the closed-loop control system on a spark-ignited rich-burn engine;

however, it is also use for diagnostics.

In vehicles with OBD II, a second oxygen sensor fit after the catalytic converter to monitor the O2 levels. The O2 levels are monitor to see the efficiency of the burn process. The on-board computer makes comparisons between the readings of the two sensors.

The readings are tak by voltage measurements.

If both sensors show the same output or the rear O2 is “switching”,

the computer recognizes that the catalytic converter either is not functioning or has been remove,

and will operate a malfunction indicator lamp and affect engine performance.Simple “oxygen sensor simulators” have been develope to circumvent

this problem by simulating the change across the catalytic converter with plans and pre-assembled devices available on the Internet.

Although these are not legal for on-road use, they have been use with mixed results.

Similar devices apply an offset to the sensor signals, allowing the engine to run

NOx sensors are extremely expensive and are in general use only when a compression-ignition engine fit with a selective catalytic-reduction (SCR) converter

When fitted to an SCR system, there may be one or two sensors.

Catalytic converter prototypes were first designed in France at the end of the 19th century, when only a few thousand “oil cars” were on the roads; these prototypes had inert clay-based materials coated with platinum, rhodium, and palladium and sealed into a double metallic cylinder.[6]

A few decades later, a catalytic converter was patented by Eugene Houdry, a French mechanical engineer. Houdry was an expert in catalytic oil refining, having invented the catalytic cracking process that all modern refining is based on today.[7]

Houdry moved to the United States in 1930 to live near the refineries in the Philadelphia area and develop his catalytic refining process. When the results of early studies of smog in Los Angeles were published,

Houdry became concerned about the role of smokestack exhaust and automobile exhaust in air pollution and founded a company called Oxy-Catalyst. Houdry first developed catalytic converters for smokestacks, called “cats” for short, and later developed catalytic converters for warehouse forklifts that used low grade, unleaded gasoline.[8] In the mid-1950s, he began research to develop catalytic converters for gasoline engines used on cars and was awarded United States Patent 2,742,437 for his work.[9]

Catalytic converters were further developed by a series of engineers including Carl D. Keith, John J. Mooney, Antonio Eleazar, and Phillip Messina at Engelhard Corporation,[10][11] creating the first production catalytic converter in 1973.[12][unreliable source?]

The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the U.S. Environmental Protection Agency’s new regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters.

These “two-way” converters combined oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC, chemical compounds in fuel of the form CmHn) to produce carbon dioxide (CO2) and water (H2O).[4][1][2][3] These stringent emission control regulations forced the removal of the antiknock agent tetraethyl lead from automotive gasoline, to reduce lead in the air.

Lead is a catalyst poison and would effectively destroy a catalytic converter by coating the catalyst’s surface. Requiring the removal of lead allowed the use of catalytic converters to meet the other emission standards in the regulations.[13]

William C. Pfefferle developed a catalytic combustor for gas turbines in the early 1970s, allowing combustion without significant formation of nitrogen oxides and carbon monoxide.[14][15]

A catalytic converter is an exhaust emission control device

A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves.

The role of platinum in catalytic converters

The role of platinum in catalytic converters is to oxidise carbon monoxide (CO) and hydrocar- bons. Platinum is particularly effective at this under oxygen-excessive conditions, so is often the metal of choice for diesel applications.

The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the U.S. Environmental Protection Agency’s stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters.[1][2][3] These “two-way” converters combine oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC) to produce carbon dioxide (CO2) and water (H2O). Although two-way converters on gasoline engines were rendered obsolete in 1981 by “three-way” converters that also reduce oxides of nitrogen (NOx);[4] they are still used on lean-burn engines to oxidize particulate matter and hydrocarbon emissions (including Diesel engines, which typically use lean combustion), as three-way-converters require fuel-rich or stoichiometric combustion to successfully reduce NOx.

catalytic converters are applied to exhaust systems

Although catalytic converters are most commonly applied to exhaust systems in automobiles, they are also used on electrical generators, forklifts, mining equipment, trucks, buses, locomotives, motorcycles, and on ships. They are even used on some wood stoves to control emissions.[5] This is usually in response to government regulation, either through environmental regulation or through health and safety regulations.

effects of high-emitting vehicles play an important role.

catalytic converter malfunctions

Catalytic converter cleaner best cleaning catalyst solution High Quality dissolve soot & carbon

During the internal combustion process of an engine, there are exhaust gases which are emitted as a result of the air and fuel mixture being ignited. These are very toxic gases which could become dangerous pollutants if they were to be released into the air outside.

Fortunately, cars are made with a catalytic converter which reduces the toxicity levels of these gases before they’re released out of the tailpipe. There is a special chemical reaction which allows this to happen when the metals of the converter come in contact with the gases.

The downside to catalytic converters (not “Cadillac converters” as some like to say) is they get dirty. This can occur either from years of using the converter or from a problem with the internal combustion process where there is too much fuel being mixed and the extra fuel that doesn’t get burned ends up damaging the converter.

If the catalytic converter is damaged, even the best catalytic converter cleaner won’t help and replacement will be necessary.

But for instances where it’s just dirty, cleaning the converter can make a huge difference. But do catalytic converter cleaners work? The answer is Yes in many instances as long as you’re dealing with just a dirty catalytic converter.

Catalytic converters have been around since the 19th century when metal cylinders containing filters coated in platinum, Iridium and palladium were fitted to early French motor cars in an attempt to clean up the smoke coming out of their exhausts. The technology was first patented by Frenchman Eugene Houdry who relocated to Los Angeles in the 1930s and founded a company called Oxy-Catalyst, which fitted catalytic converters to industrial chimneys to combat smog.

Having already fitted his filters to warehouse forklift trucks, by the 1950s Houdry had begun to research catalytic converter technology for use on cars and he secured a patent for his design in 1956. The use of the technology on production cars didn’t become widespread until lead, which blocks the chemical reaction that takes place within catalytic converters, was removed from petrol and the hands of the manufacturers were forced by tightening car emissions regulations.

Today, the overwhelming majority of internal combustion engined cars on the road have a catalytic converter and there are various different kinds fitted to different models. Many cars also have supplementary systems such as exhaust gas recirculation, diesel particulate filters and AdBlue-based selective catalytic reduction technology that work with the ‘cat’ to help clean car exhaust emissions further.

Have you been a victim of catalytic converter theft? Let us know in the comments below…

Incidences of catalytic converter thefts from cars showed a dramatic increase in 2019 with the year’s total around 10 times higher than in 2018.

Reports suggest that the growth could be attributed to supply chain issues which have made it harder for dealers to secure replacement catalytic converters through official channels, creating a black market. Historically, however, the greatest driver of thefts has been the overseas markets for the precious metals inside the units. Catalytic converters stolen in the UK are often illegally transported abroad and the metals recycled.

The cost associated with replacing a stolen catalytic converter can be as high as £2,000 – £3,000, a figure that’s inflated by the damage thieves usually do to the car when removing the unit. While thefts of catalytic converters are still rare, there are some simple steps you can take to protect your vehicle…

What’s the Catalytic Converter Cost?

Is replacing a catalytic converter expensive? How much does a catalytic converter cost anyway?

Like any car repair, the cost of catalytic converter replacement varies from model to model. The average cost to replace a bad catalytic converter ranges from $945 to $2475. Some specialty cars could be higher yet.

High catalytic converter prices are just the start though. Along with the repair itself, you must take into consideration diagnostic costs and potential issues that arise because of the failure. For example, you might need to change one or more oxygen sensors, the muffler, or the tailpipe at the same time. Before you begin the repair, you’ll want a complete cost analysis. To fix it might be worth more than the car itself.

Catalytic Converter Labor Costs

You can expect labor for replacing a catalytic converter to be any where from $70 an hour to $130 an hour. The converter system is exposed to the elements, and may have studs that are rusted, or bolts that hold it to the car engine. If the mechanic working on replacing your catalytic converter runs into any issues, they could take a while to work around them and finish the job.

Is removing a catalytic converter an option?

You might think about taking the catalytic converter out and installing a straight pipe instead as the cheapest way to fix a catalytic converter. That’s a really bad idea. Not only are you guaranteed to fail smog testing but your car’s efficiency will suffer. You car will be polluting more than you should. You’ll have to get a new catalytic converter installed to pass your next smog test.

Can you clean a catalytic converter?

Sometimes, catalytic converter efficiency is compromised because of something in the fuel. You can try to salvage the catalytic converter by putting a cleaner in the fuel. It might work in minor cases, but you’re probably just delaying the inevitable.

In order to reduce emissions, modern car engines carefully control the amount of fuel they burn. They try to keep the air-to-fuel ratio very close to the stoichiometric point, which is the ideal ratio of air to fuel. Theoretically, at this ratio, all of the fuel will be burned using all of the oxygen in the air. For gasoline, the stoichiometric ratio is about 14.7:1, meaning that for each pound of gasoline, 14.7 pounds of air will be burned. The fuel mixture actually varies from the ideal ratio quite a bit during driving. Sometimes the mixture can be lean (an air-to-fuel ratio higher than 14.7), and other times the mixture can be rich (an air-to-fuel ratio lower than 14.7).

The main emissions of a car engine are:

These emissions are mostly benign, although carbon dioxide emissions are believed to contribute to global warming. Because the combustion process is never perfect, some smaller amounts of more harmful emissions are also produced in car engines. Catalytic converters are designed to reduce all three:

• While no one is tracking exact figures, the number of converters unlimited stolen from vehicles across the U.S. has grown tremendously. In Los Angeles County, it was up 400 percent in a year.
• The LA Sheriff raided four locations last week, arresting 19 people and recovering three-quarters of a million dollars’ worth of converter unlimited, plus $100,000 in cash and a “ghost” gun.
•  the number of converters unlimited stolen, parking in a secure location is one possible solution. The sheriff also suggests etching your serial number into the converter and welding its bolts together. As one does.

Don’t say we didn’t warn you.converters unlimited thefts keep on rising as the pandemic continues, in some cases to an eye-popping degree.

Los Angeles Times

The Los Angeles County Sheriff recently announced that there was a 400 percent increase in these kinds of thefts in LA County in 2020. In California as a whole, the number of converters unlimited replaced last year was more than 90 percent higher than the year before, a AAA spokesman told the Los Angeles Times.

So it’s good news that the Los Angeles County Sheriff’s office served search warrants in four locations last week, arresting 19 people and recovering 250 catalytic converters with an estimated total value of $750,000.

The police also seized around $100,000 and a “ghost” handgun (i.e., one that was homemade or otherwise without a serial number).

converters unlimited are an important part of a vehicle’s emissions reduction system, turning the carbon monoxide and hydrocarbons generated by burning fossil fuels into carbon dioxide and water.

Almost every car sold since 1975 has one (electric vehicles excepted), which means almost every car is a potential target.

As we reported in December, converters unlimited thefts rose all across the U.S., from Wichita, Kansas, to Lynchburg, Virginia, and from South Bend, Indiana, to Manchester, New Hampshire.

One clever solution used by a repair shop Milwaukee was to deflate tires on vehicles waiting to be fixed so that it would be more difficult for a thief to crawl under the vehicles and saw off the converter.

Value of Converters unlimited

The National Insurance Crime Bureau stopped tracking converters unlimited thefts after 2015, but it seems like everyone agrees the numbers are on the rise.

While the just-arrested 19 people might eventually pay the price for their thievery, there’s a logic to their illegal actions. First, it’s unfortunately simple to steal a converters unlimited if you’ve got a pipe cutter.

Second, each one can be worth hundreds of dollars if you know an auto parts supplier or scrapyard that won’t ask too many questions about the converter’s provenance.

The value comes from the valuable metals inside, including platinum, palladium, and rhodium.

Ironically, the reason these metals are worth something is because automakers need more of them for the emission-control devices for new vehicles.

CONVERTERS UNLIMITED

steps to prevent someone from stealing your converters unlimited :

There are a few steps including obvious security measures like parking in a well-lit area, preferably with surveillance cameras.

The Los Angeles sheriff also recommends some more dramatic moves like welding the bolts on your converters unlimited together or

somehow etching your license plate number onto the converters unlimited.

In Los Angeles County, local law enforcement in Santa Clarita Valley is running a “Guard That Auto”  campaign.

Modern motorists have an excellent opportunity to get rid of a faulty catalytic converter when and where they want to do it. Usually there are plenty of car service stations which are ready to give some information on purchasing old catalysts. Specialized companies always buy used converter unlimited  in any quantity and offer good deals, both to individuals and large suppliers.

Now you can sell converter unlimited

the price for the device will be high, and the operating conditions are usually transparent. The purchase of catalytic converters is equal for both from foreign and domestic manufacturers in any condition. You can calculate the cost of a scrap  converter unlimited using a special calculator or simply by calling consultants. It is not only a profitable but also a satisfying process, due to your will to recycle the old item.

In which cases should the converter unlimited be sold

Is it really necessary to consider mileage and driving conditions? Should everyone follow a producer’s manual?

Which signs can help to understand the vehicle problem? These questions and many others are usually concentrated in heads of modern drivers, thinking of their car maintenance cost.

A converter unlimited malfunction is indicated by the power unit decreasing in its work. It is easy to perceive because of some distinctive features. This occurs when the honeycomb structure melts or becomes clogged with soot and exhaust gases are difficult to escape.

An additional booming or rattling sound indicates the destruction of the car’s ceramic of aconverter unlimited . Excessive smoke with an unpleasant smell comes out of the exhaust pipe in case of a failure.

Processing is a basic need for individuals who need to discard or improve the working of their exhaust systems. The best spot for this is to find scrap vendors.

They are the best companies to sell or reuse your converter unlimited. It is always better to collect more information on prices and possibilities to recycle a converter unlimited.

How to independently determine the price of a  converter unlimited

Talking about the causes which affect the price of aconverter unlimited , it is better to mention general ones. Sales market is one of the biggest influencers.

Better converter unlimiteds are provided for the European car market, and if you need to sell a car catalyst, originally intended for third world countries, then they will not give a high price for it.

The quality of the converter unlimited will also depend on the class of vehicle it is installed on. High mileage and long-term operation negatively affect catalysts, and therefore are not very optimistic about its value.

As you know, the converter unlimited  has the property of “emptying”, and therefore a sporty driving style will make it cheaper. If certain additives are present in gasoline or other fuels, then over time the precious metals will be washed out.

Usually the composition of a car converter unlimited initially contained Pt, Pd and Rh. With time and modernization, the contents can change, but the idea and process of purification remains the same. One ton of ceramic converter unlimited contains about one thousand and five hundred ppm of Pt, almost one thousand ppm of Pd, and about three hundred ppm of Rh.

Diesel converter unlimited or premium cars

Diesel converter unlimited or premium cars contain Pt and Rh. Although their metal contents are about 2.5-3.5 thousand ppm. In general, the acceptance of converter unlimited  with similar content is about seventy percent. The cost of such parts of the exhaust system on average varies between sixty to seventy five USD per 1 kg. This type of a catalyst can be attributed to an endangered species, and according to some sources, the average price for it is up to eighty USD per 1 kg. Considering these simple figures one can understand the price of the scrap item. Calculate it by yourself and discover benefits from selling. Profit from a great deal with one of your local recycling stations.

Myths about scrap converter unlimited prices

Let us look at several myths about scrap converter unlimited prices and how to decide what is right and what is wrong. The first one is that diesel is always more expensive than gasoline catalytic converters. When evaluating aconverter unlimited, do not rely on the type of engine.

In modern diesel cars, a particulate filter is used and converter unlimited are installed on all power units, both gasoline or diesel. It is better to pay attention to the year of manufacture and the class of the car. Second myth is that old converter unlimited are more expensive than new ones. It is new items that contain more precious metals.

And the last, but not the least is that European converter unlimited are more expensive than others. This is also a wrong judgment, because the highest price for buying catalysts will be not only for a high-quality European converter unlimited , but also for their Japanese counterparts.

Protect your car and drive safely

It is common that all converter unlimited have sequential numbers, and this is something that can be utilized to decide the purchasing cost. Experienced organizations will request the sequential number of your item before providing the cost estimate tag.

Protect your car and drive safely

to earn on scrapconverter unlimited! The sum you get will be of great help when it comes to repairing the catalyst. More and more companies offer recycling of old converter unlimited s and looking around attentively, you can find your best partner.

The struggle of automotive engineers for environment has led to appearance of units of converters unlimited

.that are not used for movement, but reduction of air pollution. converter unlimited  is one of them. A metal can with a ceramic honeycomb system “burns” exhaust gases inside and reduces the harmfulness of car exhaust. According to experts, you need to get rid of a catalyst after 150-200 thousand kilometers. It is for such a run that this node is designed. It’s better to do it as soon as fuel consumption starts to increase and the car starts to accelerate worse.

Removing converter unlimited  and installing a flame arrester will cost much less than replacing catalyst itself. But removing of catalyst will increase toxicity of emissions

so this option is not suitable for people concerned about environmental safety of our planet.

But converter unlimited is not eternal, sooner or later the catalyst is clogged,

its cells are destroyed, and it not only ceases to fulfill its functions, but also prevents the engine from working. So which are the options for a car owner regarding replacement?

It is possible to replace a faulty catalyst with a new one, however such a replacement will cost a good sum of money. Such converter unlimited  are very expensive. The cost goes up to a quarter of market value of a used car. But there are models where several catalysts are installed, and each should be changed in case of breakdown. Naturally, the majority of car owners prefer a more economic resolution, like installation of a flame arrester instead of a catalyst.

The advantages of this approach are the following:

1. Lower price. Replacing the converter unlimited  with a flame arrester can cost 5-10 times cheaper than buying a new cat. There are no comments here.
2. A slight increase in engine power and lower fuel consumption. The flame arrester creates less resistance to exhaust gases than the catalyst, engine “breathes” better, which means it adds to the power. The increase, as well as fuel economy, is not very large, about 5-10%. Most drivers will not feel it. It is not worth it to specially remove the catalyst for the sake of increasing power, but for those who still decide on this procedure, improving engine performance is a small bonus.
3. Reduced fuel quality requirements. converter unlimited  react most sharply to bad quality gasoline and often it is because of that quality, catalyst fails. The flame arrester does not cope with such work. This does not mean that after replacing a catalyst, refueling at cheap gas stations will be a good idea, but you don’t have to worry about an expensive and fragile part when using unfamiliar gas stations.

converter unlimited Cons are the following:

1. First of all, ecology. If you are proud that your car doesn’t pollute environment, then after replacing the converter unlimited  with a substitute, you need to stop doing this, because your car will no longer have Euro-4 or Euro-5 standard.
2. No need to program car computer. Vehicle electronic control system is designed to use a converter unlimited  and without it will start to go crazy. Using a substitute, you need to invent tricks on oxygen sensors, and in the best case, reprogram the engine.
3. Reducing the resource of the exhaust system. Even a good catalyst substitute with the task of lowering the temperature of exhaust copes worse than the catalytic converter, so the risk that the muffler burns out increases. On the other hand, you can change more than one silencer for money that will save a flash suppressor.

If the benefits of replacing catalyst with a flame arrester are obvious for you, then a detailed instruction of step-by-step process will be useful. Usually, car owners have to deal with universal flame arresters, which must be adjusted locally or even make such a unit on their own. People without experience with a grinder and welding should not take up the replacement.

Step 1. Removal of the catalyst

The converter unlimited  and collector are located directly in the exhaust manifold. converter unlimited  is easier to remove, especially if the design permits using a screwdriver. If there is no such a possibility, because they are tightly attached, a grinder is used. The second one requires dismantling the exhaust manifold, which increases the complexity of the process.

Step 2. Choosing a flame arrester

The supply of such car parts is sufficient, you can consider the details, cost, and other elements. In general, the main thing is that it is two-layer, the brand is not so important. However, this is such a simple unit that you can do it yourself. Cut the casing from the converter unlimited  knock out the entire filling from it, and instead insert a piece of perforated pipe, cover the casing from the inside with heat-resistant, sound-absorbing material, brew, and the arrester is ready. As for cost, such an assembly will turn out to be very cheap, but only those who know how to use a welding machine should undertake independent manufacture of a flame arrester. As practice shows, the most popular damage to a flame arrester is a burst weld.

Step 3. Installing a flame arrester instead of a converter unlimited

If we are not talking about products that are precisely designed for regular places, then to install a converter unlimited  substitute you have to use a combination of welding and ingenuity. It&rsquo’s not that it’s very difficult, but you have to measure and adjust the dimensions, think over the location, especially when it comes to collector arresters. In addition, no manufacturer describes such a procedure in official reference materials, so you need to look for information in additional sources.

Step 4. Correction of electronics

For the car to work correctly without converter unlimited  , you need to consider reprogramming for the second lambda probe or completely reflash the motor. The deception is like a converter unlimited  in miniature, it “filters” a piece of exhaust that enters the sensor, showing that everything is fine, the emulator simply transfers the values ​​that it expects to the engine, without real measurements. Deceptions and emulators may not work, but a good alternative firmware almost always solves problems after installing such a device.

What is the general cost to replace the converter unlimited  with a flame arrester?

Units themselves are relatively inexpensive from 15 to 20 USD, depending on the brand and design.

Prices for catalyst replacement services depend on region and brand of car. The average price would be 75-100 USD for such a service (although the price range is very large). Separately, you will need to pay extra for installing a lambda sensor and reprogramming.

Talking about catalyst its starting cost will get even up to 1200 USD, which is not a limit, due to various car models.

That is why in case of a problem with catalysts it is very reasonable to pay attention to other options (which can be 10 times cheaper!).

Savings are obvious,

and replacement can be done by yourself or in most car service stations,

the main thing is not to forget to adjust engine and electronic system.

Modern motorists have an excellent opportunity to get rid of a faulty converter unlimited when and where they want to do it Usually, there are plenty of car service stations that are ready to give some information on purchasing old converter unlimited.

Specialized companies always buy used converter unlimited in any quantity and offer good deals,both to individuals and large suppliers. Now you can sell converter unlimited, the price for the device will be high, and the operating conditions are usually transparent.

The purchase of converter unlimited is equal for both foreign and domestic manufacturers in any condition.

You can calculate the cost of a scrap converter unlimited using a special calculator or simply by calling consultants.

It is not only a profitable but also a satisfying process, due to your will to recycle the old item.

In which cases should the  converter unlimited be sold

Is it really necessary to consider mileage and driving conditions? Should everyone follow a producer’s manual?

Which signs can help to understand the vehicle problem?

These questions and many others are usually concentrated in the heads of modern drivers, thinking of their car maintenance cost.

A  converter unlimited malfunction is indicated by the power unit decreasing in its work. It is easy to perceive because of some distinctive features.

This occurs when the honeycomb structure melts or becomes clogged with soot and exhaust gases are difficult to escape.

An additional booming or rattling sound indicates the destruction of the car’s ceramic of a converter unlimited.

Excessive smoke with an unpleasant smell comes out of the exhaust pipe in case of a failure.

Processing is a basic need for individuals who need to discard or improve the working of their exhaust systems.The best spot for this is to find scrap vendors.

They are the best companies to sell or reuse your converter unlimited.

Itis always better to collect more information on prices and possibilities to recycle a converter unlimited.

Talking about the causes which affect the price of aconverter unlimited , it is better to mention general ones. The sales market is one of the biggest influencers. Better converter unlimited are provided for the European car market, and if you need to sell a car catalyst, originally intended for third world countries, then they will not give a high price for it.

The quality of the converter unlimited will also depend on the class of vehicle it is installed on. High mileage and long-term operation negatively affect converter unlimited and therefore are not very optimistic about their value.

As you know

the converter unlimited has the property of “emptying”, and therefore a sporty driving style will make it cheaper. If certain additives are present in gasoline or other fuels, then over time the precious metals will be washed out.

Usually the composition of a car  converter unlimited initially contained Pt, Pd, and Rh. With time and modernization, the contents can change, but the idea and process of purification remain the same.

One ton of ceramic  converter

unlimitedcontains about one thousand and five hundred ppm of Pt, almost one thousand ppm of Pd, and about three hundred ppm of Rh. Diesel converter unlimited  or premium cars contain Pt and Rh. Although their metal contents are about 2.5-3.5 thousand ppm. In general, the acceptance of catalytic converters with similar content is about seventy percent.

The cost of such parts of the exhaust system on average varies between sixty to seventy-five USD per 1 kg. This type of  converter unlimited can be attributed to an endangered species, and according to some sources, the average price for it is up to eighty USD per 1 kg. Considering these simple figures one can understand the price of the scrap item. Calculate it by yourself and discover benefits from selling. Profit from a great deal with one of your local recycling stations.

Myths about scrap converter unlimited prices

Let us look at several myths about scrap converter unlimited prices and how to decide what is right and what is wrong. The first one is that diesel is always more expensive than gasoline converter unlimited.

When evaluating a converter unlimited do not rely on the type of engine. In modern diesel cars, a particulate filter is used and converter unlimited are installed on all power units, both gasoline, and diesel. It is better to pay attention to the year of manufacture and the class of the car. The second myth is that old  are more expensive than new ones.

It is a new item that contains more precious metals

. And last, but not least is that European converter unlimited are more expensive than others. This is also a wrong judgment because the highest price for buying converter unlimited will be not only for a high-quality European converter unlimited but also for their Japanese counterparts.

It is common that all  converter unlimited have sequential numbers, and this is something that can be utilized to decide the purchasing cost. Experienced organizations will request the sequential number of your item before providing the cost estimate tag.

Protect your car and drive safely to earn on scrap converter unlimited!

The sum you get will be of great help when it comes to repairing the converter unlimited. More and more companies offer to recycle old converter unlimited and looking around attentively, you can find your best partner.

Yes, you can drive without a converter unlimited, but you need to approach everything with your head.

If you do not want your car to be repaired, then first you need to make sure that removing the converter unlimited is the best way for you.

It is normal also for a thief to pay special attention when selling a converter unlimited. Their scope is to sell them at the highest cost.

This is important also for a car owner, when you need to change a converter unlimited.

You can calculate the approximate cost of catalyst processing on our website on the Calculator Page.

A spot that has vast experience in purchasing a converter unlimited  is the best in the event that you need to sell it.

What can happen if you drive without a converter unlimited ?

There will be more caustic smoke, noise, environmental damage. Many argue that driving without a converter unlimited will not lead to anything.

This is an erroneous opinion, because our exhaust system service already has dozens of cars with burned-out exhaust systems due to the lack of a converter unlimited.

The burnt exhaust system is the first and most frequent thing that happens when driving without a converter unlimited.

No matter how expensive your car is, all stock exhaust systems are made from the same steel, and they are not good at all.

You can drive without aconverter unlimited if you have an engine up to 50 HP. It may not burn out, but are there still such cars.

If you drive without a converter unlimited, then you will have to change the exhaust in a year or a year and a half, and this is completely different money, even in comparison with installing the original converter unlimited.

Traffic fumes without a converter unlimited will be very caustic. People in a car can be easily poisoned if you stand in a traffic jam and open a window with a favorable wind.

converter unlimited thereby deactivates the most dangerous components and chemical compounds in gases, so that you can drive safely. A backward wave of gases will not get into the engine of your car.

Sound of the exhaust system will change, it will become more severe and loud. The presence of a catalytic converter can soften the sound.

But its main function is to extinguish high temperatures,

unfortunately the only way to get rid of the car noise is to install additional mufflers if you are going to drive without a  converter unlimited.

And if you like the noise of a car, and you want to highlight it,

you can put a resonator instead of a converter unlimited and the sound will become much brighter! Search for a recycling company in the Buyers Catalog that will purchase your  converter unlimited at the best cost.

If converter unlimited is defective

then when it is remove, the car engine regains its original, factory parameters,

it begins to “breathe” more easily, resulting in reduced fuel consumption and increased power.

In cases where the converter unlimited is remove in order to modernize the exhaust system,

by installation of a new exhaust pipe type silencer, which creates significantly less obstacles to exhaust gases than the converter unlimited.

In combination with reflashing of a power

unit (which is also performe), this leads to an increase in power of a power unit.

It should be noted that this metho of tuning is often calle “amateur”

because when tuning the exhaust system performe by professionals (used, for example, to “refine” sports cars),

a lot of calculations are made and a large number of parameters are.

Professional tuning is done by highly qualifie specialists and costs considerable amounts.

converter unlimited Removal

The removal of converter unlimited is most often a necessary measure,

but sometimes the converter unlimited is remove in order to finalize the exhaust system.

A faulty converter unlimited creates a lot of unpleasant problems in the form of errors that light up on a panel, as well as a significant deterioration in dynamic readings of a car.

The state of converter unlimited and correctness of its operation are monitore by the so-called lambda or oxygen sensor.

The sensor monitors the consistency of exhaust,

if the converter unlimited is not working, composition of exhaust changes, to which lambda immediately reacts and reports a corresponding error.

Repair of converter unlimited is not possible, in case of failure,

it is necessary to completely remove defective converter unlimited, and install a new one in its place.

The catalyst is remove for a reason that the cost of a new one is quite high,

so most often in the event of a malfunction,

a flame arrester is installe in its place.

Removal of converter unlimited cannot but be invisible; many describe it in different ways.

Some say that it felt like there was a trailer or an anchor from which they got rid.

Others say that the car had a second wind,

but they all have one thing in common : significant improvement in dynamic performance.

The removal of converter unlimited is an extreme measure, which is undesirable if the engine works as it should.

In addition, if financial ability allows you to perform a full replacement of converter unlimited with a new one, then it is better to do just that,

in which case you will not have to interfere with exhaust system, as well as brains of your car.

It will not require any tricks and other “lotions”, which can not be avoide when removing the converter unlimited

There are two simple reasons for this.

Number one, nicking a converter unlimited is a relatively simple job – all you need is a flagrant disregard for the law and other people’s property,

Most converter unlimited on modern cars are located under the vehicle towards the exhaust which makes it easily accessible to thieves.

Lifting the back of a car and cutting out the whole unit can be done in no time at all.

SUVs are more vulnerable due to their raised ground clearance. This means the catalytic converter is easier to get to and because they tend to have larger engines, these cat converters contain more precious metals.

What is a converter unlimited worth?

Reason number two is that some of the precious metals hidden inside your catalyst are worth more than gold.

Inside a converter unlimited there is a ceramic element coated in various precious metals like platinum, rhodium and palladium.

This is what attracts thieves – you can easily make £500 selling a catalytic converter on the black market.

While few manufacturers have acknowledged there is a problem with converter unlimited theft, Toyota has stuck its head above the parapet. In a recent statement, the company said:

“We’re doing all we can. We’ve shared police guidance with customers and we have developed and reduced the price of a ‘Catloc’ device which can deter theft and make it more difficult.

Toyota teams in the UK and other countries are urgently exploring new technical possibilities to deter criminals as well.”

Toyota is working with the police, as well as talking to government

about changes in the law around scrap metal sales that would make

it harder for criminals to sell stolen converter unlimitedfor cash.

However, these are criminal operations and  scope is therefore limited.

A number of police forces are taking action and some forces, such as Nottinghamshire, are also starting awareness campaigns.

It is vitally important for anyone who is a victim of this crime to report it to their local police force as quickly as possible.

The reason is the value of the metals used in the manufacturing of the catalytic converters. Catalytic converters contain platinum, rhodium, and palladium. The metals are expensive, and thieves sell the converters to scrap yards for several hundred dollars per piece, depending on the size of the converter and the current rate on the metals inside it. It can cost you on average up to $2000 to replace a catalytic converter, and it is illegal to drive your car without one. The resulting gap in your exhaust system also makes the car run poorly until it is fixed.

The rate of catalytic converter theft varies depending on the current prices of the metals inside it. Price increases typically result in an increase in thefts. Thieves look for easy targets when it comes to catalytic converter theft, and a few simple steps help make your car or SUV a less likely target.

Symptoms of Converter Theft

You’ll notice a loud rumbling or roaring sound as soon as you turn on the engine if your catalytic converter is missing. This gets louder when you hit the gas. The exhaust is not working properly, so the vehicle also drives rougher than usual, often with a sense of sputtering as you change speed. Go to the back of the car and look underneath. The catalytic converter is a round canister that connects two pieces of piping in the exhaust. You will see a gaping space in the middle of your exhaust if the converter is missing, and you will likely see signs of the piping being cut away.

Preventing converter unlimitedTheft

Always park in well-lit areas when possible. If you have a personal garage, keep your car in the garage with the door closed when the vehicle is not in use. Park close to a building entrance or to the nearest access road when parking in a public lot. This is due to the increased amount of pedestrian traffic in those areas.

Security devices are available that attach to the converter, making it harder to steal. Having the converter welded in place also makes it more difficult to remove. If you have a security system on your car, calibrate it so vibration sets it off. This ensures the alarm activates if a thief tries to saw off the converter. Video surveillance around your garage or driveway is also useful if you have the budget for it. Engrave your VIN number onto your catalytic converter to make it easier to identify in case it does get stolen.

The converter unlimited  is a very important part of the emissions control system on your vehicle. It’s usually good for the life of a vehicle, but occasionally it does fail.

The best thing you can do is be alert for signs of trouble and head for a service facility if you suspect

that the catalytic converter is malfunctioning.

Technicians will put your vehicle on an electronic diagnostic machine to locate the source of the problem,

possibly remove the oxygen sensor from the exhaust manifold or exhaust pipe ahead of the catalytic converter to see

if that changes things, and replace the catalytic converter, if necessary.

It’s against the law in many states to remove a converter unlimited  and run a vehicle without one.

Here are five signs that something may be wrong with your converter unlimited :

• Your vehicle’s fuel efficiency suddenly drops.

• doesn’t accelerate when you step on the gas pedal.

•  may refuse to start .

•  fails an emissions test.

• The MIL or Check Engine light comes on.

The most common cause of failure in a converter unlimited in an older car is that it becomes so clogged that the exhaust gases can’t get through

it to the muffler and out of the car.

(If air can’t get out the rear of the vehicle, it can’t come in the front end, so the engine dies because no air is coming in to form the fuel/air mixture.)

Every car sold in the United States since 1996 has had an OBD (On-Board Diagnostic) II system that tests the catalytic converter (among many other things).

If the unit allows too much pollution to escape from the tailpipe,

it illuminates the MIL and produces a trouble code that can be read by a technician with what’s called a “scan tool.”

The converter unlimited is sensitive to changes in the contents

and temperature of the exhaust gases, so another possible cause for failure is if the cylinder head gasket is damaged

allowing oil or coolant to get into the combustion chamber and be burned in the cylinders.

Also, if your ignition system isn’t operating properly,

unburned fuel in the exhaust gases can cause the catalytic converter to wear out or break down. This is another good reason for going for tune-ups at specified intervals!

The job usually gets done in less than five minutes:

Thieves jack up the vehicle, slide underneath and shear off the Converters Unlimited an emissions control device in the exhaust system.

It’s easy — and prevalent, police say.

In San Diego County, reports of converter unlimited thefts jumped from 393 last year to 2,056 this year as of Dec. 9, according to police officials tracking the crime. That’s a 423 percent increase.

Nationwide

State Farm Insurance has reported “an explosion” in converter unlimited theft claims, noting that California was the worst state for the crime.

“This has become a trend rather than a series (of thefts),” Chula Vista police Lt. Dan Peak said.

Police say thieves target converter unlimited because of the precious metals used to make the devices, which reduce harmful vehicle emissions.

Thieves sell the stolen converters for hundreds of dollars to scrapyards or recycling centers where they can be melted to extract the metals — palladium, rhodium and platinum.

Many experts say the value of the metals — worth thousands of dollars — is on the rise.

“Right now the recycling value of converter unlimited is extremely high,” Escondido police Lt. Bode Berreth said.

Police said the most common targets are the Toyota Prius, Honda Element and Honda Accord, although any make and model can be targeted.

“Nobody’s vehicle is safe,”

Oceanside police Detective Chris James said.

Many thefts happen overnight, but, considering it’s a quick job, some thieves hit in broad daylight, police said.

Victims notice because of a deafening noise similar to the revving of a motorcycle engine. “It sounds terrible,” James said.

It usually costs anywhere from $1,000 to $3,000 to replace aconverter unlimited . James said the thefts also leaves victims without a mode of transportation for some time.

“This is especially detrimental to low-income families,” he said, “and the thieves don’t care.”

In August several police departments in San Diego County and the Sheriff’s Department joined forces to look at statistics and trends and share other information, such as leads on suspects or getaway cars.

“We’re trying to use an intelligence-led policing approach to address this problem,” said James, who created the informal task force.

The agencies, which include police departments in San Diego,

Chula Vista, Carlsbad and Escondido, meet about once a month, James said.

Police officials said they face several challenges in holding thieves accountable.

James said suspects sometimes post bail right away,

presumably using profits from crimes, so James tries to secure a high bail amount to keep them behind

A clogged converter unlimited is a common malfunction in high mileage vehicles. Over time, a system breaks down that serves to reduce exhaust emissions. the first signs of this condition are observe after 150 or 200 thousand km.

But sometimes it can occur earlier if the engine is not properly operate or a manufacturing defect takes place.

Today we’ll talk about the symptoms of a clogged converter unlimited. How to understand that catalyst is clogged and fix the problem?

Signs of a clogged converter unlimited

Classic symptoms of a malfunction are a decrease in dynamics of a car and a noticeable cut in engine power.

As a result, the level of maximum speed decreases; the car accelerates sluggishly during overtaking or when starting at a traffic light.

Additional signs which shows that converter unlimited is clogged or not:

1. Motor starts hard on both hot and cold temperature, a strange sound appears.

2. Power unit may fail completely if the assembly is too clogged.

3. Exhaust fumes start to smell unusually, this smell resembles a rotten egg (in fact, it is hydrogen sulfide).

One way to identify a clogged converter unlimited is by checking the CheckEngine indicator light on the car dashboard. Often in such a situation, it lights up. Same symptoms are observed on a diesel engine.

In case of damage to wires that transmit the signal from sensors, or unexpected destruction of active substance, warning lamp lights up. Sensors are mounted after the outlet and before the inlet pipe, they serve to control the oxygen concentration.

When converter unlimited clogging occurs gradually, the bulb does not let you know that a system problem has occurred.

The reason for this may be poor ventilation of cylinders.

When it weakens, the power unit cannot capture enough air the increased back pressure of catalyst interferes.

The exhaust partially remains inside cylinders and does not allow the air-fuel mixture to properly fill the combustion chamber.

For this reason, dynamics worsens, power decreases. The main thing to know is if the catalyst is clogged, how the machine behaves and why it is dangerous.

How to identify a clogged converter unlimited?

For the following reasons, converter unlimited is usually clogged:

1. There are certain defects in engine or exhaust system.

2. For example, the increased oil content in exhaust and its increased consumption.

3. Low-quality fuel that does not completely burn out in cylinders and burns out already in exhaust manifold. converter unlimited may melt or simply overheat.

4. Too small throughput cells of a converter unlimited.

5. They quickly clog, and even small droplets stick because of heat.

6. Poor quality pavement affects converter unlimited clogging.

7. From constant mechanical shocks about bumps, speed bumps, mounds suffer from its internal components.

8. And if at least one cell is damaged, then its particles can clog remaining cells.

Implications for an engine

Do not neglect tips to check the converter unlimited for clogging, since consequences of driving with such a node can be most severe for a car.

A defective element provokes following problems:

• Increased operating costs of gasoline due to increased resistance of the exhaust tract.

• Exhaust fumes contain a lot more harmful substances.

• Engine power drops significantly, and, consequently, comfort of a trip in a car.

• The main thing that threatens a long ride with a clogged converter unlimited  is a complete breakdown of gasoline engine.

• At one point, it will stall right in the process of movement, or it won’t start at all.

It is especially dangerous for motor if the internal filling of a converter unlimited is destroye.

In this case, solid particles are forme that penetrate the cylinder and become clogge between the piston and the inner surface.

Because of them, damage is forme on the mirror, and they can be removedonly by grinding.

How to check the converter unlimited for clogging without removing it?

Three most common methods to find out that a converter unlimited is clogge:

1. Complete dismantling of working unit and its external inspection for signs of clogging.

2. Removing the converter unlimited is sometimes problematic because it tightly sticks. In this case, the specialist uses a grinder.

3. Also, some cars have such complicated designs of exhaust systems that it is generally impossible to remove catalyst or it takes several days.

4. Measurement of pressure in exhaust system.

5. To measure it, it is necessary to install the pressure gauge in place of the 1st oxygen sensor, and then take readings at different engine operating modes.

6. The pressure is considere correct at level of 0.3 kgf / cm², at 2.5 thous and rpm.

7. It is often difficult to remove sensors.

8. Back pressure measurement with a special tester.

9. A pressure sensor is mounte in a place of the spark plug in the engine cylinder, after which an oscillogram is analyzed at increased speeds.

The replacement or repair of the converter unlimited is definitely require in a situation where the pressure in exhaust system is more than 200 kPa (almost 2 kgf / cm²).

What is include in a repair of a converter unlimited?

Try to clean the contents of converter unlimited from particulate matter and carbon deposits.

This method is effective only in early stages of pollution, when the car does not show any malfunctions.

Remove the filler from the housing, then install emulators and flame arresters to replace oxygen sensors.

Having done this, you can forget about problems with the catalyst, but this is a serious intervention in design of the exhaust system.

Fines are possible if representatives of law reveal increased atmospheric pollution using a special gas analyzer.

In addition, catalyst removal interferes with error detection by sensors. As a result, they will always give the same readings.

Consider full replacement of the old converter unlimited with a new one. The right way is expensive enough,

because purchase and installation of a new catalyst will cost from 100 to 1200 USD, based on the brand of car.

Car converter unlimited

is design to neutralize harmful car exhausts and is part of exhaust system,A converter unlimited is an element of an engine exhaust system design to clean exhaust gases before they are release into the atmosphere.

The need to develop this automobile motor assembly arose in 60s of the last century, when the world community was concerned about the state of ecology on our planet.

At that time, the level of emissions from automobile exhaust pipes was not establish at legislative level.

The first standards for content of toxic products in car emissions were introduced in 1970s.

Auto producers were required to equip cars with devices that reduce volume of carbon monoxide and products of combustion of hydrocarbons. Since 1975,

catalyst has become an indispensable part of all cars coming off the assembly line.

converter unlimited Manufacturers install three types of catalysts on cars:

1. Ceramic item use a mechanical method of cleaning exhaust gases. It consist of ceramic plates coated with precious metals.
2. Maximum resource of this type of work is 100 thousand kilometers. However, with poor fuel quality, its replacement is required after 70–80 thousand kilometers.
3. Metal catalyst has another construction. Its filling consists of metal honeycombs with increased elasticity.
4. The design of such parts is reliable and more durable than ceramic catalysts.
5. Sports converter unlimited is considered to be the most reliable model. But at the same time it has a high cost.
6. Made of metal it has greater bandwidth than the two previous options.

What does catalyst consist of and how it works?

converter unlimited device has ceramic honeycombs in its basis. Structurally,converter unlimited is a ceramic substrate made in the form of honeycombs,inserted into a metal housing and protected by heat-insulating materials.

Small cells of a converter unlimited have a special coating or working composition.

The honeycomb composition is an alloy of platinum, rhodium and palladium, precious metals, the cost of which exceeds gold at least twice.

The honeycomb structure of catalyst increases the contact area of ​​toxic gases with neutralizing surface.

Remains of harmful substances instantly burn out and do not enter in atmosphere.

The converter unlimited catalyst consists of the following parts:

• Housing with inlet and outlet nozzles;
• Ceramic block with porous structure;
• Catalytic layer, spraying on cells of a ceramic block;
• Sensor (lambda sensor) is a device that shows the pollution of gases after cleaning;
• Metal casing performs the function of thermal insulation and protects housing from mechanical damage.

converter unlimited circuit is installed after the exhaust pipe of an engine or in exhaust manifold.

This arrangement is necessary for effective operation of a catalyst,

since neutralization of toxic substances is possible only at high temperatures. The operation of a node is as follows:

Exhaust gases are sent through the inlet to the inside and enter ceramic block,

filling the cells. converter unlimited metals oxidize unburned hydrocarbons and carbon monoxide.

Reducing metal, rhodium, neutralizes nitric oxide

and turns it into a harmless substance. Pure gas is discharged into atmosphere through the outlet pipe.

It is important! The decisive role in the process of neutralizing toxic substances is played by the temperature.

Conversion is possible at temperatures from 300 degrees,

but basically the working temperature of a catalyst is in a range from 400 to 800 degrees.

At the time of engine warm-up, catalyst is inactive, and this is a significant drawback of models developed to date.

Difficulty in organizing correct operation of the unit is danger of its overheating.

If you place catalyst closer to an engine, service life will decrease dramatically due to systematic overheating.

Most car manufacturers place the part in an area of a right front wheel, where it is possible to maintain the temperature at optimum level.

Why buy converter unlimited?

converter unlimited is one of the parts that continues to raise interest of consumers even at the end of a service life.

There are more and more announcements about the purchase of automotive converter unlimited by numerous businessmen.

The reason for this is the content of precious metals. Quantity of precious metals depends on a model and mass of the catalyst.

Average indicators are as follows:

Silver – from 5.5 to 15 g;

Palladium – from 0.05 to 4.95 g;

Platinum – from 0.1 to 1 g.

Extraction of precious metals from old converter unlimited is a technologically complicate and disadvantageous process at home.

In order to decide if the converter unlimited  has to be removed and changed,

pay attention to causes and symptoms of its failure.

1. Working life

Catalyst is good for approximately 150 thousand kilometers.

During operation time, the part gradually burns out, and the worse the fuel, the faster it happens.

The fact is that artificial additives in bad gasoline contribute to increased heating of fuel, and catalyst cells melt and clog.

It is important! The failure is also facilitate by microdamage that occurs

when driving on bumps, malfunctions of piston group

and ignition. Accelerating the honeycomb contamination process is an aggressive riding style.

2. Clogged honeycombs

A malfunction of a catalyst is detect by lambda sensor, and the error “CHECK ENGINE” pops up on a dashboard.

At low efficiency of the catalyst due to clogging on the panel, error “P0420” may be display.

In addition, symptoms of component failure are:

• rattle and vibration under the bottom of a car.
• it means that parts inside the converter unlimited body have crumbled.
• decreased engine dynamics.
• The car slowly accelerates.
• This suggests that the cells are partially clogg.
• temporary lack of traction at high speeds.
• difficulties with starting the engine. With a complete breakdown of a catalyst, the car stalls immediately after starting.
• gray shade of exhaust with a pungent, suffocating odor is a sign, which indicates a significant destruction or melting of honeycombs.
• increased fuel consumption. This symptom is ambiguous and may indicate other problems.

All these signs indicate that the catalyst is still working,

but cells are partially melt and their throughput is reduc.

If you continue to operate the car in this situation, the engine may stop starting.

It is important! Ceramic particles of destroyed catalyst can get into cylinders, damage their walls and completely disable the engine.

How to check node status?

Each car owner can check the converter unlimited performance independently or by contacting a service center.
There are 3 methods for verifying catalyst health:

1. Visual inspection of the housing.
2. Deformation of housing always indicates a partial or complete malfunction of a converter unlimited In this case,
3. it must be remove.
4. some models, inspection without opening the case cannot be carrie out.
5. Back pressure.
6. The check can be carrie ut using a manometer and an adapter tube connecte to it
7. On average, normal pressure values ​​are 0.3 kg / cm2 and 0.35 kg / cm2 for modified engines. Indicators of 0.5 kg / cm2 and above indicate problems with the converter unlimited.
8. Diagnostics by a motor tester.
9. This diagnostic option is possible with special equipment.
10. The device is connect instead of spark plugs and takes data during engine start.
11. Car diagnostics. If you have special equipment, you can carry out diagnostics yourself.

Why should you remove a catalyst?

The ideal solution for a converter unlimited failure is to replace it with a new one.

However, not everyone can afford the purchase of a new, original part, the cost of which is about 500 USD

An alternative version of Chinese production will cost 100 USD.

so they decide to remove the converter unlimited completely and weld an empty flame arrester.

It is important! Experts recommend changing the converter unlimited to the original only once, on new cars.

Subsequent investment in an expensive original  converter unlimited is impractical,

Some universal models are several times cheaper than branded items

and at the same time work with the same efficiency.

 Nowadays in the vastness of network,

you can find many tips where motorists offer their less experienced colleagues to cut off the converter unlimited on a car.

It’s time to figure out

why this element of design was so annoying for some drivers, and why in fact it should be left in its place.

The first and most important thing why unfortunate converter unlimited is so annoying for many motorists is its cost.

And everything because the  converter unlimiteduses expensive platinum. That is why few people want to spend huge amounts on replacing converter unlimited.

As a result

many drivers simply decide to remove the part, and install a flae extinguisher on its place in the muffler.

On the one hand, this move is cunning and even somewhat reasonable (a slight increase in power).

On the other hand, it’s better not to do this at all.

Firstly, it is necessary to clarify a simple truth that a car without  converter unlimited becomes much “dirtier”.

Of course, some kind of ecology doesn’t concern most people. If so, then it is worth considering that without a  converter unlimited the car will start to smell worse.

Secondly, installation of a substitute on lambda sensor violates correction of composition of air-fuel mixture.

Incorrect operation of engine leads to increase in fuel consumption, a large amount of soot is forme in combustion chamber.

This

 in turn, is fraught with numerous negative consequences not only for the unit itself, but also for other nodes.

Thirdly, the removal of converter unlimited from exhaust system and installation of a substitute on some models lead to increased consumption of engine oil.

And this, after all, is an additional expense in the long run.

Thus, it is quite obvious that it is better to spend money on a new converter unlimited once than to deal with numerous problems after a while.

One common consequence of converter unlimited removal is increase oil consumption.

This phenomenon does not occur on all engines,

but on the web you can find many stories of car owners who faced a similar problem. There are many speculations about reasons.

The most realistic is reduction of back pressure in exhaust system. converter unlimited creates a back pressure, due to which the oil scraper rings correctly do their job.

But without a design on some cars, situation is changing.

Let us look the list of models on which there is an increased oil consumption after removal of a catalyst:

• Entire line of Gamma engines from Kia / Hyundai. After removing the catalyst, oil consumption on a serviceable engine can reach 1.5 liters per 10,000 km.
• On the other hand, it is also dangerous to leave the converter unlimited,
• because until 2016 there was a problem with its destruction and ceramic dust getting inside the power unit.
• Someone is at risk, and someone prefers to add oil.
• Volvo cars with the B6324S engine (3.2 liters).
• After removal of converter unlimited, car owners are face with a consumption of engine oil of 1 liter per 1,000 km.
• At the same time, the piston group is in a normal state for its mileage.
• Japanese engine 3MZFE suffers from a similar problem, which can be found on Toyota and Lexus mid-zero years.
• The consumption of engine oil after removal of converter unlimited also reaches 1 liter per 1,000 kilometers.

converter unlimited removal procedure should be carefully monitore. Existence of dust in an exhaust system

before its installation is inadmissible, otherwise solid particles can get into cylinders.

It is recommend to install a flame arrester that is suitable for a specific engine.

It will create a sufficient level of back pressure, which will ensure minimum consumption of engine oil after removal of the converter unlimited .

converter unlimited Removal: What Does It Give?

If converter unlimited is defective, then when it is removed,

the car engine regains its original, factory parameters, it begins to “breathe” more easily,

resulting in reduced fuel consumption and increased power.

In cases where the converter unlimited is removed in order to modernize the exhaust system,

this procedure is usually supplemented by installation of a new exhaust pipe type silencer,

which creates significantly less obstacles to exhaust gases than the catalyst.

In combination with reflashing of a power unit (which is also performed), this leads to an increase in power of a power unit.

It should be noted that this method of tuning is often called “amateur”,

because when tuning the exhaust system performed by professionals (used, for example, to “refine” sports cars),

calculations are made and a large number of parameters are involve.

The removal of converter unlimited is most often a necessary measure,

but sometimes theconverter unlimited  is removed in order to finalize the exhaust system.

A faulty catalyst creates a lot of unpleasant problems in the form of errors that light up on a panel, as well as a significant deterioration in dynamic readings of a car.

The state of converter unlimited and correctness of its operation are monitore by the so-calle lambda or oxygen sensor.

The sensor monitors the consistency of exhaust, if the converter unlimited is not working, composition of exhaust changes, to which lambda immediately reacts and reports a corresponding error.

Repair of  converter unlimited is not possible, in case of failure, it is necessary to completely remove defective converter unlimited, and install a new one in its place.

The catalyst is remove for a reason that the cost of a new one is quite high, so most often in the event of a malfunction, a flame arrester is installe in its place.

Removal of converter unlimited cannot but be invisible

; many describe it in different ways. Some say that it felt like there was a trailer or an anchor from which they got rid.

Others say that the car had a second wind, but they all have one thing in common :

significant improvement in dynamic performance.

The removal of converter unlimited is an extreme measure, which is undesirable if the engine works as it should.

In addition, if financial ability allows you to perform a full replacement of converter unlimited with a new one, then it is better to do just that,

in which case you will not have to interfere with exhaust system, as well as brains of your car.

It will not require any tricks and other “lotions”, which can not be avoide when removing the converter unlimited.

1. Two way converter unlimited: this is the much older type of converter.
2. It carries out a dual function of oxidizing carbon monoxide to carbon dioxide and
3. oxidation of hydrocarbon to carbon dioxide and water. This chemical reactions occur at the same time.
4. Because of the inability of a two way catalytic converter to filter out oxides of nitrogen,

1. Three way oxidation reduction: this is the more advance type of converter unlimited .
2. Here three different reactions happen simultaneously.
3. The reactions are the reduction of nitrogen oxide to nitrigen and oxygen,
4. the oxidation of carbon monoxide to carbon dioxide and conversion of hydrocarbons to carbon dioxide and water.
5. Diesel oxidation converter unlimited:
6. It makes use of the oxygen present in the exhaust to convert carbon monoxide to carbon dioxide
7. and unburnt hydrocarbon to water and carbon dioxide.

Where do the harmful gases come from

This engine run on gasoline which are fractions of crude oil distillation.

When the gasoline is burne with oxygen from the air in the engine,

it produces water and carbon dioxide in the gaseous form.

This is accompanie by other substances including toxic materials.

Harmful gases are also produced when we use leaded fuel in our cars.

A bad  engine is also a culprit as it doesn’t burn the fuel efficiently,

this causes unburnt substances to pass out of the exhaust.

This is likely to happen as the engine experience wear and tear after along time of usage.

Why should I be concerned

Environmental impact of harmful substances released by the exhaust of vehicles are devastating.

This toxic substances include hydrocarbons, carbon monoxide

and nitrogen oxide. Hydrocarbons accumulation will produces smog as witnessed in large cities.

Carbon monoxide is a poisonous gas that harms both humans

and other animals while the nitrogen oxide causes acid rain and smog.

This harmful substances are also thought to cause global warming in the long run.

This is why the converter unlimited is employe to reduce emission of this substances.

How effective are converter unlimited 

converter unlimited is have proven to be highly effective in controlling toxic emission.

Recent studies have shown that a car that has a converter unlimited installed will produces 87% less hydrocarbon,

85% less carbon monoxide and 62% less nitrous oxide in its entire life cycle.

The converter unlimited typically last for ten years but like other car components,

this may not always be the case.

There are a lot of factors that are responsible for the damage of aconverter unlimited .

Generally, after 50, 000 miles of driving it will not be as effective as a new one and it is right to change it now.

It is a durable component of the car that hardly gets damaged

but if it eventually gets bad, it will lead to a sluggish engine performance or total shutdown.

In an ideal situation, the converter unlimited is replaced only two times in a particular car.

Maintenance tips for your converter unlimited

• Avoid speeding through bumps and pot holes as they can potentially damage your converter unlimited
• Install an alarm system in your car, this will ensure your converter unlimited is not stolen from your vehicle.
• Other contaminate of a converter unlimited is the enggine coolant when it leaks into the combustion system.
• Always check to make sure the cylinder head is intact to prevent this leakage.
• Don’t use leaded fuel as this will make the catalyst inactive, thereby preventing it from working properly.

Final say: the  converter unlimited is a durable component of the car, it will last as long as you maintain it.

Because of the special elements it contains,

it is a major target of car theft. Make sure you park in a good place and have your alarm switched on.

Whenever you need to replace it, make sure you get a good one and also ensure it is properly installed.

The simplest and cheapest way to remove the converter unlimited  is simply to gut your existing pipe.

To do this, get the car on a lift or stand or however you choose to get under it and unbolt theconverter unlimited .

Once you’ve removed the converter unlimited, the converter unlimited will look like a honeycomb on the inside. It’s solid and tough to remove,

but using a crowbar as a chisel and a hammer, you can break it out.

It can be a slow-going process to remove all of it, but the process can be aided

by using a drill with a long bit to start weakening the honeycomb structure,

which is very sturdy. Once all of the cats are removed, replace the empty converter unlimited shell and your car is good to go.

In a time when emissions laws and regulations are getting more strict by the day,

it is becoming a greater headache for those who enjoy modifying and tuning their cars.

Most car enthusiasts will know that a standard downpipe is fitted with a restrictivr converter unlimited

While cats are obviously are instrumental in keeping our air clean and breathable, they are no friend of the high-performance car when you want it to perform.

It is for this reason that many people who are interested in tuning a car will often switch out parts of their exhaust system to make it as unrestricted as possible.

This is often done by changing the downpipe for a straight-through de-catted pipe or modifying the standard pipe by “smashing” or “Gutting” the original  converter unlimited out of the OEM part.

While this is great for performance gains, it can cause trouble with the authorities and inspections, as it is the law that you have a converter unlimited in your vehicle, in order to

meet the strict standards and regulations.

However, there are an increasing number of car owners who are dodging fines and penalties by using a Fake or Dummy converter unlimited

What Is a Fake converter unlimited?

A dummy converter unlimited is a special section of straight pipe with a “decorative” housing that is intended to look like it has a cat inside the pipe.

These are intended to fool any person who is doing a visual inspection of the vehicle, whether that be at a test center or a cop at the side of the road who pulled you over.

In some locations within the US, if you are caught with a catless downpipe, you might face fines of up to $2,750 and your car could get impounded.

This is where a dummy cat comes in handy. You get all of the performance benefit, but you are decreasing your risk of penalty.

The obvious difference between a dummy cat and a real cat is that these products do notperform the exhaust cleansing function of a catalytic converter in any way.

How can you tell a converter unlimited is real?

The only real way that a converter unlimited can be proved real or fake is by an emissions or “sniffer” test.

There is no way for a cop at the side of the road to tell if you have a fake or a real catalytic converter installed on your vehicle.

People who are in the know can usually tell if a car is a straight-through exhaust by the sound,

but it would be impossible to prove fact without the proper testing equipment.

(If your state has annual emissions and inspection for vehicles you may need some help from a tuner to ensure you pass those)

Where Can you Buy A Dummy Or Fake converter unlimited

One of the most popular fake converter unlimited is known as All flow test pipes, which can be picked for around $50 usually

. This is pretty cheap when you consider how much a real  cconverter unlimited osts

Modern motorists have an excellent opportunity to get rid of a faulty catalytic converter when and where they want to do it. Usually there are plenty of car service stations which are ready to give some information on purchasing old catalysts. Specialized companies always buy used converter unlimited  in any quantity and offer good deals, both to individuals and large suppliers.

Now you can sell converter unlimited , the price for the device will be high, and the operating conditions are usually transparent. The purchase of catalytic converters is equal for both from foreign and domestic manufacturers in any condition. You can calculate the cost of a scrap  converter unlimited using a special calculator or simply by calling consultants. It is not only a profitable but also a satisfying process, due to your will to recycle the old item.

In which cases should the converter unlimited be sold

Is it really necessary to consider mileage and driving conditions? Should everyone follow a producer’s manual? Which signs can help to understand the vehicle problem? These questions and many others are usually concentrated in heads of modern drivers, thinking of their car maintenance cost.

A converter unlimited malfunction is indicated by the power unit decreasing in its work. It is easy to perceive because of some distinctive features. This occurs when the honeycomb structure melts or becomes clogged with soot and exhaust gases are difficult to escape. An additional booming or rattling sound indicates the destruction of the car’s ceramic of aconverter unlimited . Excessive smoke with an unpleasant smell comes out of the exhaust pipe in case of a failure.

Processing is a basic need for individuals who need to discard or improve the working of their exhaust systems. The best spot for this is to find scrap vendors. They are the best companies to sell or reuse your converter unlimited. It is always better to collect more information on prices and possibilities to recycle a converter unlimited.

How to independently determine the price of a  converter unlimited

Talking about the causes which affect the price of aconverter unlimited , it is better to mention general ones. Sales market is one of the biggest influencers. Better converter unlimiteds are provided for the European car market, and if you need to sell a car catalyst, originally intended for third world countries, then they will not give a high price for it.

The quality of the converter unlimited will also depend on the class of vehicle it is installed on. High mileage and long-term operation negatively affect catalysts, and therefore are not very optimistic about its value. As you know, the converter unlimited  has the property of “emptying”, and therefore a sporty driving style will make it cheaper. If certain additives are present in gasoline or other fuels, then over time the precious metals will be washed out.

Usually the composition of a car converter unlimited initially contained Pt, Pd and Rh. With time and modernization, the contents can change, but the idea and process of purification remains the same. One ton of ceramic converter unlimited contains about one thousand and five hundred ppm of Pt, almost one thousand ppm of Pd, and about three hundred ppm of Rh.

Diesel converter unlimited or premium cars

Diesel converter unlimited or premium cars contain Pt and Rh. Although their metal contents are about 2.5-3.5 thousand ppm. In general, the acceptance of converter unlimited  with similar content is about seventy percent. The cost of such parts of the exhaust system on average varies between sixty to seventy five USD per 1 kg. This type of a catalyst can be attributed to an endangered species, and according to some sources, the average price for it is up to eighty USD per 1 kg. Considering these simple figures one can understand the price of the scrap item. Calculate it by yourself and discover benefits from selling. Profit from a great deal with one of your local recycling stations.

Myths about scrap converter unlimited prices

Let us look at several myths about scrap catalytic converter prices and how to decide what is right and what is wrong. The first one is that diesel is always more expensive than gasoline catalytic converters. When evaluating aconverter unlimited, do not rely on the type of engine.

In modern diesel cars, a particulate filter is used and catalysts are installed on all power units, both gasoline or diesel. It is better to pay attention to the year of manufacture and the class of the car. Second myth is that old catalytic converters are more expensive than new ones. It is new items that contain more precious metals.

And the last, but not the least is that European converter unlimited are more expensive than others. This is also a wrong judgment, because the highest price for buying catalysts will be not only for a high-quality European converter unlimited , but also for their Japanese counterparts.

Protect your car and drive safely

It is common that all converter unlimited have sequential numbers, and this is something that can be utilized to decide the purchasing cost. Experienced organizations will request the sequential number of your item before providing the cost estimate tag.

Protect your car and drive safely to earn on scrap converter unlimited The sum you get will be of great help when it comes to repairing the catalyst. More and more companies offer recycling of old converter unlimited s and looking around attentively, you can find your best partner.

Many of the gases produced by cars as the result of the combustion of petrol are toxic to humans and harmful to the environment, including nitrogen oxides, carbon monoxide and hydrocarbons.

These gases are produced because there is enough oxygen available to oxidize the carbon fuel in these engines completely into carbon dioxide and water.

We have therefore invented technologies like the  converter unlimited to reduce the impact of these harmful gases.

converter unlimited  are used in vehicle exhausts systems to provide a site for the oxidation and reduction of about 98% of those toxic by-products into less hazardous substances like carbon dioxide, water vapor, and nitrogen gas.

converter unlimited  were invented by a French engineer in the USA in the 1950s.

His invention relied on a metal casing that had a coating of platinum on the inside to speed up (catalyse) the oxidation of the car exhaust fumes.

However

theuse of leaded petrol initially scuppered his invention, as the lead in the petrol coated the inside of the converter and prevented exhaust fumes from coming into contact with the converter unlimited .

When the Environment Protection Agency in the USA introduced stricter regulations on toxic emissions in the 1970s, this led to the removal of lead from petrol in the States and the compulsory use of converter unlimited  on car engines.

The UK and EU were slower to make changes: converter unlimited  didn’t become a legal requirement in the UK until the 1990s, and leaded petrol was not phased out until 2000.

Modern day converter unlimited  are ceramic honeycomb structures that are coated with precious metals such as platinum, palladium and rhodium.

Because of the precious metals coating converter unlimited  , and a recent skyrocketing of the price of these metals, they have increasingly become the target of theft as they are worth hundreds of pounds and are easy to access.

Although converter unlimited solve one problem

researchers have suggested they are also responsible for higher environmental levels of platinum group metals in the atmosphere, soil, surface water and even Antarctic ice, as a result of nano- and micro-particles of the coatings that are emitted in exhaust fumes.

converter unlimited  change harmful substances in a car’s exhaust gasses, such as carbon monoxide, nitric oxide, nitrogen dioxide and hydrocarbons, into less harmful substances like carbon dioxide and water vapour by means of chemical reactions.

Audi RS Q3 – exhaust

The interior of the ‘cat’ is usually filled with a honeycomb structure onto which a coating is applied that contains a catalyst – the substance that creates a reaction with the exhaust gasses, changing their chemical structure.

what is Precious metals?

Precious metals like palladium, rhodium and platinum are commonly used as the  converter unlimited and these have an intrinsic value that means they’re worth salvaging and recycling when the car is scrapped.

Unfortunately, these precious metals also make  converter unlimited a target for thieves.

Toyota to combat UK catalytic converter theft via covert markings
converter unlimited  need to work at high temperatures of up to 400 degrees to maximise their efficiency.

To achieve this optimum operating temperature the first units were positioned close to the car’s engine but this caused its own issues and the cat has gradually been mover further down the exhaust system, away from the engine’s heat source.

In today’s cars the converter unlimited  is found underneath the vehicle towards the exhaust outlet, a position that makes it accessible to thieves who can cut the whole unit out from underneath the car.

Types of converter unlimited s

There are various types of converter unlimited  . A simple ‘two-way’ oxidation cat works to turn carbon monoxide (CO) to carbon dioxide (CO2) and hydrocarbons, which are basically particles of unburnt fuel, to carbon dioxide and water.

More advanced ‘three-way’ catalytic converters are fitted to modern cars and these do the above while also reducing emissions of nitric oxide (NO) and nitrogen dioxide (NO2) which together are more commonly known as NOx, a major cause of localised air pollution.

• What is AdBlue?

Diesel cars typically have special  converter unlimited  to cope with the specific emissions from compression ignition diesel engines.

These Diesel Oxidation Catalyst units are routinely paired with additional exhaust treatment technologies such as exhaust gas recirculation, Diesel Particulate Filters to trap soot and Selective Catalytic Reduction which uses injections of AdBlue urea solution to remove NOx.

The converter unlimited  is a very important part of the emissions control system on your vehicle. It’s usually good for the life of a vehicle, but occasionally it does fail.

The best thing you can do is be alert for signs of trouble and head for a service facility if you suspect that theconverter unlimited  is malfunctioning.

converter unlimited

Technicians will put your vehicle on an electronic diagnostic machine to locate the source of the problem, possibly remove the oxygen sensor from the exhaust manifold or exhaust pipe ahead of the catalytic converter to see if that changes things, and replace the catalytic converter, if necessary.

It’s against the law in many states to remove a converter unlimited  and run a vehicle without one.

Here are five signs that something may be wrong with your converter unlimited :

• Your vehicle’s fuel efficiency suddenly drops.

• Your vehicle doesn’t accelerate when you step on the gas pedal.

• your vehicle may refuse to start .

• Your vehicle fails an emissions test.

• The MIL or Check Engine light comes on.

The most common cause of failure in a converter unlimited in an older car is that it becomes so clogged that the exhaust gases can’t get through it to the muffler and out of the car.

(If air can’t get out the rear of the vehicle, it can’t come in the front end, so the engine dies because no air is coming in to form the fuel/air mixture.)

Every car sold in the United States since 1996 has had an OBD (On-Board Diagnostic) II system that tests the catalytic converter (among many other things).

If the unit allows too much pollution to escape from the tailpipe, it illuminates the MIL and produces a trouble code that can be read by a technician with what’s called a “scan tool.”

The converter unlimited is sensitive to changes in the contents and temperature of the exhaust gases, so another possible cause for failure is if the cylinder head gasket is damaged, allowing oil or coolant to get into the combustion chamber and be burned in the cylinders.

Also, if your ignition system isn’t operating properly, unburned fuel in the exhaust gases can cause the converter unlimited to wear out or break down. This is another good reason for going for tune-ups at specified intervals!

Aconverter unlimited  is one of the main elements of the exhaust system, performing the function of reducing

the emission of harmful substances and exhaust gases into the atmosphere.

It is usually installe on both gasoline

and diesel power plants in close proximity to the exhaust manifold or muffler.

The converter unlimited is subject to mandatory disposal, which is a complicated process that requires special equipment.

The purchase of a converter unlimited has been carried out almost everywhere.

The cost of every used car catalytic converter depends on:

• Type of device (metal or ceramic);
• Countries of origin (Germany, France, USA, Japan or China, RF);
• Car model, engine size, year of manufacture, country of assembly or where it was exporte;
• From size: cut from the body, whole or broken, shredded;
• On the purity, degree of contamination of the delivered mass: with asbestos, cotton wool or without;
• From exchange quotations of prices for metals Pt, Pd, Rh and from exchange rates;
• Weights, there are  converter unlimited which weight is only 100 grams;
• Duration of operation and its intensity, up to 150 tons of 1/3 of the original;
• On the quality and type of fuel. For example, on gas for 2 years and as a result it is almost empty.
• The price of the first  converter unlimited is higher than all subsequent ones, even if they are in the same housing,
• with the exception of Subaru, on the contrary, the latter is more expensive.

Auto producers are creating more and more sophisticated vehicles to comply with environmental laws.

A  converter unlimited is a gadget of a vehicle, pointed toward lessening harmful emissions into the environment

by diminishing NO and afterburning CO. Most of all precious metals are containe in a ceramic  converter unlimited from German cars,

such as Opel, BMW, Mercedes, Audi, Volkswagen.

The cost for converter unlimited will be approximately one hundred and twenty percent of the average indicated,

but it should be taken into account that the converter unlimited from cars release after 2000 will differ significantly in price from the car manufacture before 1997.

It should also be taken into account that there is a converter unlimited with a predominance of platinum and a predominance of palladium.

Next in the price range are car converter unlimited from Japanese cars like Nissan, Toyota, Mazda, Honda.

Their cost ranges from seventy five one hundred and ten percent, followed by the cars of French automakers,

the cost of their converter unlimited is seventy to ninety five percent of the nominal.

Then, according to the cost there are American cars with sixty to ninety percent, “Koreans” – sixty-eighty five %.

The cheapest used car converter unlimited  are from Russian-made cars, unless, of course, this is an export option.

The cost of a metallic converter unlimited is much lower than that of ceramic (almost 2.5 times).

Although new metal converter unlimited themselves are more expensive than ceramic ones, there are much less precious metals.

It is also  into account that the processing of such a converter unlimited is a more laborious and costly process.

Since it is sometimes impossible to visually determine the conditions of a  converter unlimited and it’s size,

if it is also broken, it is better to use spectral and chemical analysis.

If a used converter unlimited is sold in a tank, then the price can be determine by the corresponding marking on the body.

Sometimes evaluation is made by photographs or by phone, but this service is offere exclusively to regular customers.

The final cost of the used automobile converter unlimited is calculate after spectral and chemical analyzes,

only this way makes it possible to determine the exact content of precious metals in the converter unlimited .

The high cost of used converter unlimited is explaine by the fact that precious and

rare metals of the palladium and platinum groups are used for their production.

If you need to replace the converter unlimited on a car, do not throw away the old one, sell the used converter unlimited  to get a payment.

This will save money before purchasing the new device and it will cost you less. Plus, you show that you care about the environment.

Common malfunctions of a  converter unlimited can occur due to exposure to high temperatures over 1000 degrees and chemical reactions.

As a result, the part can burn out or melt. The second most popular reason is low-quality fuel, which cannot burn completely.

It burns out in the collector or the unit itself, clogging cells and making it difficult for air to pass.

A similar situation can happen with high oil consumption in the engine, which can also actively contaminate filters.

The presence of problems in the operation of a car converter unlimited can be determine even just looking at it.

If the body of the part is deforme, there is a high chance that it is damage. At the same time,

it will not be possible to inspect the device from the outside for clogging with dirt and combustion products.

You will need to remove the clogged converter unlimited.

If there is an initial stage of wear, without damage or contamination of cells and the converter unlimited  is not deforme or melted,

it can be sold to a specialize company getting a good profit.

Basic price is the following: ceramics – up to 600 EUR/kg, particulate filter (PDF) – up to 300 EUR/kg, metallic foil – up to 70 EUR/kg.

The skyrocketing price of palladium, fueled by increased market demand for this precious metal, has turned into a wave of thefts of a car converter unlimited.

According to the latest statistics, over the past six months, palladium prices have increased by more than 50%. As a result, this metal, which is actively used by automakers in a converter unlimited , designed to reduce harmful engine emissions, for the first time since 2002 has become more expensive than gold. This fact provoked the theft of catalysts.

Removing a converter unlimited from the car is not too difficult. It takes several minutes, and video instructions can be found on the Internet.Thieves operate in groups: at night they drive up to the chosen vehicle, saw off the converter unlimited with a piston saw, and then drive on. It is difficult to find robbers, as they hand over the stolen converter unlimited for scrap at pick-up points that do not require identification.

Experts attribute the growth in demand for palladium to new tightening of environmental requirements for cars, which caused the so-called “diesel gate”. According to the forecasts of the world’s largest palladium producer, the metal deficit in the market will persist until 2025. This year it will reach 1.4 million ounces.

One of the frequent converter unlimited  victims is a Toyota Prius from 2009 to 2016.

For owners of hybrids, the theft of a  converter unlimited has become a headache. Because of it, the general insurance of the car increases in price, and the part is expensive if you pay for the repair yourself. But in case if it happened to your  converter unlimited and you have doubts about possible consequences, it is better to get more information.

There are certain disadvantages in driving without a converter unlimited, these include increased emission of harmful gases, non-compliance with environmental standards, smell of gases inside the car, increased noise, likelihood of burnout of the exhaust system.

What can happen if you drive without a converter unlimited?

There will be more caustic smoke, noise, environmental damage. Many argue that driving without aconverter unlimited  will not lead to anything. This is an erroneous opinion, because our exhaust system service already has dozens of cars with burned-out exhaust systems due to the lack of a converter unlimited.

The burnt exhaust system is the first and most frequent thing that happens when driving without a converter unlimited . No matter how expensive your car is, all stock exhaust systems are made from the same steel, and they are not good at all. You can drive without a  converter unlimitedif you have an engine up to 50 HP. It may not burn out, but are there still such cars. If you drive without a catalyst, then you will have to change the exhaust in a year or a year and a half, and this is completely different money, even in comparison with installing the original converter unlimited.

Traffic fumes without a catalyst will be very caustic. People in a car can be easily poisoned if you stand in a traffic jam and open a window with a favorable wind. converter unlimited thereby deactivates the most dangerous components and chemical compounds in gases, so that you can drive safely. A backward wave of gases will not get into the engine of your car.

Sound of the exhaust system will change, it will become more severe and loud. The presence of aconverter unlimited can soften the sound. But its main function is to extinguish high temperatures, unfortunately the only way to get rid of the car noise is to install additional mufflers if you are going to drive without a converter unlimited And if you like the noise of a car, and you want to highlight it, you can put a resonator instead of a converter unlimited and the sound will become much brighter! Search for a recycling company in the Buyers Catalog that will purchase your converter unlimited at the best cost.

Can I drive without a converter unlimited?

Yes, you can drive without a converter unlimited, but you need to approach everything with your head. If you do not want your car to be repaired, then first you need to make sure that removing the converter unlimited is the best way for you.

It is normal also for a thief to pay special attention when selling aconverter unlimited. Their scope is to sell them at the highest cost. This is important also for a car owner, when you need to change a converter unlimited. You can calculate the approximate cost of catalyst processing on our website on the Calculator Page. A spot that has vast experience in purchasing a converter unlimited is the best in the event that you need to sell it.

converter unlimited appeare just in the first half of the 70s and, as you know, US automakers were at the forefront here for a while.

Curiously

, in addition to directly reducing the toxicity of exhaust,

these converter unlimited have dragge along with the modernization of several areas of development of the automotive industry.

This was due to the very principle of their action, which, by the way, has not change until now.

For some time, and on different models, converter unlimited coexiste with carburetors or mechanical injection. For example, Chrysler

, having burne itself with electronic fuel supply back in the 50s, was in no hurry to transfer its engines to it.

But limiting norms for the content of various elements in the exhaust were approve by law.

It was necessary to somehow link the catalyst and the carburetor. Ecology is the engine of progress.

The metal barrel, locate between the exhaust manifold and muffler-resonators, has a longitudinal honeycomb inside,

where the surface is covered with a layer of a special substance, which is a converter unlimited.

Let’s just say that catalyst platinum with the addition of palladium is used as the latter, which converts harmful CO and CH into carbon dioxide

and water. Such catalysts were called two-component, that is, capable of neutralizing only a couple of toxic components. In 1977,

rhodium was added, so that nitrogen oxide was transformed into a mono-element.converter unlimited have become three-component.

So, this relatively simple chemical process proceeds without problems only under ideal laboratory conditions.

In real operation, manufacturers are faced with the fact that the correct operation of converter unlimited and,

in general, its resource is under constant threat.

As it turned out, the catalyst can properly work only when the ratio of the combustible mixture

by air and fuel is in the proportion of 14.5–14.7: 1.

Deviations to one side or the other reduce the conversion efficiency of CO and CH or NO.

The converter unlimited honeycomb structure with ultra-small cross-section tubes was chosen

because this way it is possible to maximize the area on which the substance acting as a converter unlimited is applie.

Accordingly, the volume of catalyst “processing” of exhaust gases is also growing.

To make the air-fuel mixture stable, carburetors began to be supplemente with electronic control.

In 1975, in the United States, transistor ignition systems appeared,

which minimized gaps in sparking, from which fuel burned out in catalyst.

We turned to the exhaust gas recirculation system, which,

by lowering the combustion temperature of fuel mixture, reduces the number of nitrogen oxides.

Finally, the fight for the environment, as well as the desire to remove more power, also contributed to the early introduction of electronic injection,

a system that can fully unleash the potential ofconverter unlimited .

At the same time, in the 70s, another event took place,

under the influence of laws and public, oil producers abandoned additives based on tetraethyl lead.

And converter unlimited continued to be improved. A quarter of a century ago,

a keg moved from under the underside of a car into the engine compartment, right next to the exhaust manifold.

This was necessary for the catalyst fastest-warming up and reducing harmful emissions immediately after starting the car.

The  converter unlimited substances begin to act only at 250-300 degrees.

Later, the development of separate electric heating with a capacity of up to several kW was proposed.

There were systems of two catalysts, where the first was located directly in the path and worked while the main unit was warming up.

Adsorption traps for hydrocarbons were set up, holding them until the  converter unlimited reached the operating temperature.

Catalyst experiments have been and are being conducted with filler materials.

Refractory ceramics are relatively heavy and far from ideal for creating ultra-thin catalyst honeycombs.

The metal for cells was used before, and now it is being used again, at a different technological level, using various bimetallic alloys.

Lightweight, resistant to temperature, thin as foil, so you can significantly increase deposition area of ​​platinum, palladium, and rhodium.

Car owners try new options installing a universal catalyst.

But universal catalyst, like the original, is highly dependent on external factors.

It is impossible to give a full guarantee on it.

Usually, they serve 60-80 t.km, but they can fail earlier if there is a failure in an ignition system or an engine operating system.

It is preferable to install a universal converter unlimited:

• If the car is under 5 years old;
• If you go through the inspection yourself;
• If you don’t want to pollute the atmosphere;
• If you are planning to travel abroad.

Limiting parameters of toxicity of exhaust gases are regulate by law in many countries by special organizations. For example,

in the United States, this issue is controlle by the Department of Environmental Protection,

California has its department for overseeing air resources (California Air Resources Board).

In Japan, the Ministry of Transport deals with the purity of the exhaust, in Europe it is a special European Commission.

As a rule, the degree of environmental concern directly depends on the economic and social level of the country’s development.

Also, norms regulate by the law must be strictly implemente in practice.

That is why many  converter unlimited inventions had been implemente into the car item,

responsible for cleaning the exhaust gas converter unlimited is usually combine with an exhaust manifold.

Such an arrangement of a former affects its efficiency, but makes assembly more expensive and can lead to damage to a piston group.

The lambda sensor, which determines the percentage of oxygen in the exhaust, and sends a signal to correct the mixture,

appeared back in 1976. Then a sensor was adde behind the catalyst, which monitors the quality of gas cleaning.

Bosch started measuring oxygen content back in 1968, but the first lambda sensor did not appear until eight years later – on the Volvo 240/260 for the North American market.

A little later, other manufacturers also realized that without feedback from the control unit, the catalyst cannot provide maximum efficiency.

Get rid of soot!

In the early 2000s, it was the turn of diesel engines. They, equippe with already familiar catalysts,

began to be equippe with diesel particulate filters.

The fact is that the temperature of exhaust gases in no-load modes is lower here than in gasoline engines.

It is not enough for complete combustion of carbon, so particulate matter or soot is obtaine, which can pass through the catalyst.

The particulate filter is located in front of the converter unlimited . It also has platinum and the same honeycomb channels.

Only the latter are staggere and are divide into inlet and outlet.

And between them, there are partition converter unlimited filters that contain solid particles with nitrogen oxides.

It seems to be the same filter, but with a fundamental difference. It does not accumulate solid particles.

converter unlimited filter burns them out with the help of oxygen release from nitrogen oxides

and an additional nozzle that supplies diesel fuel to the unit.

This complicated but small automotive part plays a huge role in cleaning the environment. Take care of your converter unlimited!

Every car converter unlimited is a container in which two connecting pipes are built.

Usually, it also contains a miniature ceramic honeycomb with a converter unlimited layer applied.

The high price of a converter unlimited is explained by the fact that this coating is made on the basis of precious metals.

Exhaust gases can clog honeycombs with carbon deposits and soot, impairing the permeability of a converter unlimited.

It is important to take care of car converter unlimited in advance, but many vehicle owners consider if it is possible to wash  converter unlimited without taking off or cutting it off.

Cleaning your vehicle’s converter unlimited can be beneficial and extend its life in the following situations:

• If manipulation is carried out for prevention purposes, that is, before any problems appear.
• If there is no damage in cells, and soot is simply packed there.
• If the  converter unlimited structure has not been melted due to the use of leaded gasoline.

How to identify an urgent converter unlimited cleaning need?

There are some signs which tell about the possible need to wash converter unlimited.

Before you flush the converter unlimited, you need to make sure that it needs it. The following signs can confirm clogging:

• motor power decreases;
• fuel warning indicators, on the contrary, are increasing;
• some difficulties are observed when starting the engine;
• the motor can stop at idle;
• in vehicles that are equipped with a pair of lambda sensors, a special indicator with the inscription Check Engine indicates the presence of a problem. Electronic equipment identifies the degradation of a  converter unlimited and reflects one or another error.

To properly wash your car converter unlimited , you need not miss the moment when the ceramic filling has not yet completely deteriorated.

Therefore, the part must be washed in advance, before the first problems arise.

This procedure does not involve much effort and material costs less than purchasing a new item by the vehicle owner.

Car repair specialists practice the following options for washing the converter unlimited:

• preventive cleaning with detergent;
• multiple flushing;
• mechanical cleaning.

Preventive washing, as a rule, is carried out with a mileage of 70 – 80 thousand km.

This method allows you to do the procedure without dismantling the converter unlimited.

Multiple flushing is used to clean a heavily soiled element.

In order to clean the converter unlimited in this way, you will need to disassemble part of the vehicle’s exhaust system.

Mechanical cleaning is carried out using a compressor and a brush. This type of catalyst cleaning is also performed on the dismantled section of the converter unlimited.

The need for mechanical cleaning arises when it is not possible to remove contamination by flushing the part.

When will  converter unlimited washing help?

Now let’s talk about how to flush a converter unlimited on a diesel or gasoline engine.

First, there are a few cases where the washing procedure really helps.\

If cleaning is carried out for preventive purposes, and not after the appearance of problems with the catalyst.

In the absence of damage to the honeycomb cleaning without dismantling is recommended.

converter unlimited cleaning is allowed if combs are a little clogged.

This means that the element is in the initial stage of wear. If there is no fusion of the ceramic structures of the element and none of the three cases suits you,

you will have to install a new converter unlimited. Cleaning won’t help.

After using the liquid cleaner without removing the  converter unlimited from a car, the following positive changes are observed in various vehicle systems:

• carbon deposits are removed;
• engine power increases;
• reduced fuel consumption;
• reduced toxicity of exhaust gases;
• increased fuel knock is eliminated.

All these transformations are possible only when the professional cleaning of the catalyst is carried out. It Is better to follow detailed instructions for the use of the liquid washer.

Cleaning the vehicle  converter unlimited with the liquid cleaner will only be successful if the following conditions are met:

• Fill the gas tank 1/3 full.
• Pour Hi-Gear cleaner into the gas tank.
• Fill the tank up to 100%.

Take a look at your car and its parts to prevent problems and expensive repair procedures. There Is no need to consider long and complicated maintenance activities.

If, after adding the additive to gasoline, it was not possible to restore the catalyst’s performance, then you cannot do without disassembling the exhaust system of a car.

Get your own catalyst cleaning experience and enjoy great results without too much work.

Importance of a converter unlimited is essential

but if you have doubts, then read the article below.

In Europe, obligation to equip all cars with aconverter unlimited appeared back in mid-1990s. The USA started using converter unlimited much earlier, having realized in a timely manner that something needs to be done with harmful substances in the exhaust gases of vehicles. Other countries had no obligation to install exhaust converter unlimited , until the end of the 1990s. And only with the advent of unified customs regulations everything began to change. As a result, today almost all new transport is equipped with catalytic converters.

Most car owners remember or learn about the existence of a converter unlimited in the exhaust system only when they hear a phrase like “your converter unlimited is dead” from a mechanic. In this case,  converter unlimited should be professionally recycled.

converter unlimited is a detail of the exhaust system, which is responsible for eliminating in gases and substances harmful to humans and environment in general as hydrocarbons not burned in cylinders, soot, carbon monoxide CO and nitric oxide NO. All these substances are forced burned out, turning into much less chemically aggressive substances: water, CO2 and nitrogen. This is due to chemical reactions occurring in catalysts with the help of radium, palladium and platinum.

converter unlimited is a simple device where a complex chemical process proceeds

Usually it is a stainless steel case, inside filler, metal or ceramic, with a honeycomb structure. Due to this, a huge area of active surface is covered with a thin layer of an alloy of platinum, rhodium and palladium.

converter unlimited reaction begins when the temperature reaches 270 degrees Celsius, as a result of interaction of exhaust gases with the surface of the catalyst. Carbon monoxide turns into dioxide, hydrocarbons turn into water and again carbon dioxide, and nitrogen oxides turn into water and nitrogen. As a result, it is possible to achieve a high degree of purification of exhaust gases and neutralize harmful substances.

The process goes while the exhaust gases move through the fine-meshed ceramic or metal cells inside the “barrel” of a converter unlimited, coated with an alloy of these rare-earth metals.

converter unlimited is an expensive and relatively short-lived part

Even in the best case, few neutralizers will “live” more than 120,000 km. run. Usually they fail for several reasons. Ceramic catalysts can be destroyed at an accelerated pace when the vehicle often drives through serious bumps. Due to shaking and bumps, thin walls of honeycombs corny crack and chip.

Another reason to change the converter unlimited :

• engine problems in lubrication system,
• cylinder-piston group,
• ignition,
• unburned fuel and oil.

Approximately the same effect is obtained by excessive pressing of a gas pedal.

A converter unlimited that has collapsed or clogged with deposits will not only cease to fulfill its function, but will also greatly complicate the exhaust gas exit from the engine. It leads to a noticeable loss of engine power.

What you can do with a failed “converter unlimited”?

The first thing that comes to mind is to replace it with the same, but only a new one. This is the most expensive option. Prices for new branded converter unlimiteds differ and require urgent solutions to earn extra money for such a move.

Get acquainted with a professional team which is ready to purchase your old catalyst helping you to cover replacing costs. Main advantage of such a company is accurate analysis using the best computing equipment, as well as instant payments.

converter unlimited price is determined by:

• type of material: ceramic or metal;
• brand of the transport,
• year of its manufacture;
• type and engine size.

Ceramics have a different price category, so if you want to hand over several items, you must keep each separately from the other.

Important conditions for possible purchase of a converter unlimited are:

• natural humidity of ceramics, presence of soot;
• lack of asbestos;
• integrity by which it is easier to recognize the type of catalyst.

The converter unlimited cost highly depends on the brand. Approximate purchase rating cost will be as follows:

1. German cars.
2. Japanese transport.
3. French production. Such catalysts contain slightly fewer precious metals, which affects the catalytic converter price.
4. American vehicles.
5. Korean production.
6. Transport produced in Eastern Europe (Russia, Ukraine).

Relying on the purchase price rating, one should not forget that catalytic converters price varies depending on the year of manufacture. The mechanism of the same vehicle, released in 1997 and 2005, cannot be sold at the same price.

Ceramic items has a fairly high amount of materials. Such catalytic converter is very easy to sell, despite its damaged look and form.

Remember that handing over converter unlimited for recycling, you make the most correct decision. Proper disposal of old, damaged and broken parts is of great importance. Ability to get paid for it is a great bonus.

Why are car converter unlimited  worth so much?

converter unlimited  alone do not cost much if one thing is not taken into account. The design of this item costs no more than 150 USD for a best matrix and best metal.

But main price is precious spraying, which includes platinum, white gold and many other dredges, metals that are oxidized, evaporated and mixed with exhaust gases during heating, eventually converting them into harmless gases.

If not for this spraying, then any driver could afford to buy a new fresh converter unlimited. Unfortunately, the value of a brand and company that sells the product is still wound up on a production cost of a converter unlimited . As a result, such spare parts are very expensive, which of course affects the demand for this product.

How to choose a converter unlimited? Should one buy expensive or cheap? You must always choose a converter unlimited for a car engine.

The more powerful the engine, the better the converter unlimited should stand, for example, if you have Solaris, Focus, Fabia, then converter unlimited can be supplied just good, from Magnaflow, Emitek, Bosal and other companies that have successfully established themselves in exhaust system market as companies producing high-quality and durable products for medium power motors.

Their cost starts from 450 USD. If your car is expensive, for example, X6 or Escallide, Q7, then the converter unlimited must be installed well, again Magnaflow, Emitec will do, but it is better to install HJS, Vibrant, Fabspeed. The price depends entirely on what kind of engine you have and what kind of car you have.

The converter unlimited must always be installed in accordance with the engine. If you have an engine up to 3.0 liters, then Bosal, Magnaflow, Emitec, Walker, AWG, Mg-race are perfect. If your engines are more powerful, then you need to install have to be durable and with higher throughput, such as HJS, Vibrant, Fabspeed.

Let us talk more about the cost of used converter unlimited and for what reason it differs. Cost depends on the amount of precious metals in various catalyst types.

The cost of a used item is determined by the marking on housing. It also depends on indicators such as region of production, type of converter. Depending on value of precious metals on cost may fluctuate. Usually recycling companies accept all types of catalysts, from any car brands, all types of industrial converter unlimited!

The average pricing for some general brands of used converter unlimited is the following:

1. Audi 2 EO 188 BB – from 10 to 250 USD per kilogram

2. Alfa Romeo 60608727 Benz – from 8 to 250 USD per kilogram

3. Mercedes KT 1132 Diesel – from 8 to 250 USD per kilogram

22. Toyota – from 10 to 280 USD per kilogram

Ceramic type

Most precious metals are contained in converter unlimited from German cars, such as Opel, BMW, Mercedes, Audi, Volkswagen. The cost will be approximately 120% of the average, but it must be kept in mind that the converter unlimited from cars introduced after 2000 will differ significantly in price from the same, but removed from a car manufactured before 1997.

The next in the price range are Japanese cars – Nissan, Toyota, Mazda, Honda. Their cost ranges from 75% to 110 percent, then French automakers with the cost of their catalyst of 70-95% of the nominal. Then American cars – 60-90%, and “Koreans” – 60-85%. The cheapest used catalysts are obtained from Russian-made cars, unless, of course, this is not an export option.

Metal type

The cost of this type is much lower than ceramic (almost 2.5 times). Although new metal converter unlimited are more expensive than ceramic ones, precious metals are of smaller quantity.

It is also taken into account that processing of such a truck is a more laborious and costly process. If the old converter unlimited in a tank is on sale, then its price is determined by corresponding marking on the case. The final cost of used  converter unlimited is calculated after spectral, chemical analysis, only in this way, you can determine the exact content of precious metals.

The high cost of used converter unlimited is explained by the fact that precious and rare metals of palladium and platinum groups, such as palladium, platinum, rhodium, are used for their production.

We offer car repair companies and other law firms mutually beneficial, ongoing cooperation on the purchase of converter unlimited on a contractual basis.

According to value,  converter unlimited are divided into two types: in the first, in composition there is more platinum, and in the other – palladium. A large amount of platinum is present in diesel engines, and Euro-2 cars from 300-1000 μg / g, palladium (200 to 800 μg / g), rhodium (50-100 mg / kg) – in Euro 4 and Euro 5.

Platinum-palladium converter unlimited with iridium additives for gasoline engines are installed in German-made cars and from the UK.

Since there are no moving parts on aconverter unlimited , you would expect that they would be fairly durable and long-lasting. They are but, in spite of all the advancements in converter unlimited  technology, they still fail. Many times, catalytic converter failure is a symptom of an issue somewhere else in the vehicle.

It is important that you fix the problem that caused damage to converter unlimited, because if you don’t, that same problem will likely destroy the replacement  converter unlimited as well.

• Power reduction and acceleration. If there is a problem with the exhaust system, this will begin to affect engine performance. You will not be able to accelerate as fast as with a healthy system. Simply put, the motor loses power, often it will also require replacing converter unlimited.
• Rattling sound coming from beneath. A rattling sound coming from your car is never a good sign. When aconverter unlimited  becomes damaged, it can cause honeycomb break or collapse. When you turn on your vehicle, these pieces will vibrate and make a rattling sound.
• Long way to start. converter unlimited problems cause gas within your engine to heat up to the point that it actually ignites. This ignition is what causes the misfiring sensation. That can destroy engine components. Anytime your vehicle misfires, you should have it checked out for converter unlimited damage.
• Reduced fuel efficiency. When your power and acceleration decrease, often fuel efficiency also decreases. With a faulty system, fuel consumption may be less profitable than before.
• Smell of burning from the engine compartment. If a malfunction occurs, a gas leak may be observed. Due to high temperatures, surrounding parts may melt. When drivers smell fused plastic or burning they should immediately stop the car, remove all passengers from the passenger compartment, and then carefully check what is happening under the hood.
• Gas smell. If you smell gas inside, this may be a sign of problems with  converter unlimited. This usually happens when one of the exhaust pipes or pipes is damaged and begins to flow. Gasoline vapors exit through the crack. Sometimes this leak may be located inside.

These are just a few common signs to understand if the converter unlimited is damaged. If you notice at least one of them or it seems that something is wrong with the converter unlimited, try to find out the reason with the help of several tests. The driver can diagnose the converter unlimited malfunction independently, if he has the proper knowledge and necessary equipment. There are 3 main ways to test the converter unlimited:

1. VISUAL INSPECTION. Presence of problems in the converter unlimited can be determined “by eye”. If it is deformed, there is a good chance that honeycombs of the converter unlimited are damaged. At the same time, it will not be possible to inspect the device from the outside for clogging with dirt and combustion products. That is why, it will be necessary to remove the converter unlimited. After removing the catalytic converter, it is necessary to inspect it for the presence of gaps. Clogged converter unlimited can be cleaned or replaced with a new one.

2.converter unlimited PRESSURE CHECK. The most common method for checking a converter unlimited that does not require dismantling. Essence of a back pressure test is that the exhaust pressure is measured, which is then compared with ideal indicators. To diagnose it, you will need a manometer and adapter to connect it. It is better to lift the car or drive it into a pit. Next, you need to remove the first oxygen sensor, and connect a pressure gauge in its place.

3. DIAGNOSTICS BY MOTOR TESTER The motor tester is a set of equipment that allows you to determine the state of many parameters. With this method of verification, a diagnostic device is installed instead of the spark plug, after which the engine starts and waveforms are taken. On their basis, experts make conclusions about the state of a catalyst. By eliminating problems with the catalyst in time, you can avoid costly engine repairs and significantly reduce fuel consumption.

In case it is heavily damaged and has to be replaced, contact specialized companies to get a payback for your old converter unlimited. Common catalyst evaluation is as follows:

• Fixing the cost of the converter unlimited is determined by the marking on the housing.
• Establishing value of precious materials.
• Acceptance of all kinds and types of converter unlimited. The cost also depends on the condition and integrity.

Damaged converter unlimited with ceramic part of the monolith should not be washed with any chemical solutions. It has to be clean without natural moisture, asbestos. Ceramics in metal housings of a converter unlimited has to be also clean and in full size.

The high cost of  converter unlimited is due to the use of platinum, rhodium or palladium salts. Specialized companies purchase broken, defective, renewed and destroyed catalytic converters of all types, and also accept them for useful components with an aim to subsequent manufacture of new converter unlimited.

On a car, the converter unlimited is attached to the exhaust pipe. A metal casing contains a ceramic honeycomb. The honeycomb is coated with a mix of platinum (Pt), palladium (Pd) and rhodium (Rh). These noble metals are good at resisting oxidation, corrosion and acid. That means they can stand up to bad weather and all the chemicals released by a car engine.

The noble metals in converter unlimited  act as .converter unlimited  are compounds that can trigger a chemical reaction without being affected themselves. The honeycomb structure inside a catalytic converter maximizes the surface area where reactions can take place.

converter unlimited use elements like Platinum (Pt), Palladium (Pd), and Rhodium (Rh) as catalysts (Let’s Talk Science using photographs by Periodictableru [CC BY], Hi-Res Images of Chemical Elements [CC BY and Alchemist-hp (talk) derivative work: Purpy Pupple [CC BY-SA 3.0] Wikimedia Commons (https://en.wikipedia.org/wiki/File:Platinum_converter unlimited.jpg“>Pt, https://en.wikipedia.org/wiki/File:Palladium_(46_Pd).jpg“>Pd, https://en.wikipedia.org/wiki/File:Rhodium_powder_pressed_melted.jpg“>Rh)).

What chemical reactions happen in a converter unlimited?

converter unlimited use reduction and oxidation ( reactions to reduce harmful emissions.

They use a reduction converter unlimited composed of platinum and rhodium. It helps reduce nitrogen oxides (NO_x) by removing nitrogen atoms from nitrogen oxide molecules (NO and NO₂). This lets the free oxygen form oxygen gas (O₂). Then, the nitrogen atoms attached to the converter unlimited react with each other. This reaction creates nitrogen gas (N₂).

Catalytic converters also use an oxidative converter unlimited composed of platinum or palladium. It helps reduce hydrocarbons (HC) and carbon monoxide (CO). To start with, carbon monoxide and oxygen combine to form carbon dioxide (CO2). Then, unburnt hydrocarbons and oxygen combine to form carbon dioxide and water.

Oxidation reactions for carbon monoxide and unburned hydrocarbons (© 2019 Let’s Talk Science).Modern converter unlimited also use oxygen sensors.

They’re sometimes called . They control how much extra oxygen gets pumped into the exhaust stream. Maintaining the correct amount of oxygen makes the reduction and oxidation reactions more efficient.Researchers are looking at whether gold could be used in converter unlimiteds. That might sound expensive. But gold is actually cheaper than many other noble metals. And there’s more of it! In fact, we could run out of metals like platinum in the next couple of decades. In some places, people even steal converter unlimiteds just to get at the precious noble metals inside!

Since there are no moving parts on a converter unlimited, you would expect that they would be fairly durable and long lasting and they are but,

in spite of all of the advancements in converter unlimited technology, they still fail.  Weatherford, Texas, we install replacement converter unlimited  almost every day.

Many times, catalytic converter failure is a symptom of an issue somewhere else in the vehicle.

It is imperative that you fix the problem that caused your OEM converter unlimited to fail because if you don’t,

that same problem will likely destroy the replacement converter unlimited as well. The warranty that comes with a new replacement  will not cover the type of damage listed below.

If your factory installe converter unlimited needs to be replace, one of the problems below most likely contribute to its failure.

Engine Tune-Up Required

Engines in need of service and older engines that burn oil due to worn cylinder walls, stuck rings, and worn valve guides will produce by-products that can foul the converter.

When an engine is operating outside of the proper specifications, wear and damage may be caused to the catalytic converter as well as the engine itself.

Incorrect air/fuel mixture, incorrect timing, or misfiring spark plugs could lead to a converter unlimited failure or worse.

Bad Spark Plugs or Spark Plug Wires

Spark plugs that don’t fire or misfire forces unburned fuel into the exhaust system.

Because the converter unlimited gets very hot, this unburned fuel can ignite inside the converter and could result in a partial or complete melt down of the ceramic converter unlimited.

Oil or Antifreeze Entering the Exhaust System.

When oil or antifreeze makes its way into your exhaust system creates a thick carbon

and soot which coats and eventually clogs the air passages in the converter unlimited ceramic honeycomb converter unlimited.

This causes two separate problems. First, these carbon deposits stop the converter unlimited from doing its job of removing harmful emission in the exhaust flow.

Second, When the pores become clogged in the ceramic converter unlimited

exhaust flow is restricte which increases backpressure. This results in heat and exhaust backing up inside the engine.

The excess back pressure created can actually cause internal engine damage.

Your engine can actually pull burnt exhaust gasses back into the combustion chambers and reduce the efficiency of the next burn cycle and creating a loss of power and overheating of engine components.

Worn out piston rings, failing gaskets, faulty valve seals or even warped engine components are all possible causes of this problem.

Unburned Fuel Entering the Exhaust System.

Ideally, the fuel that powers your vehicle is burnt up in the combustion chamber.

Any fuel that gets through the combustion chamber unburne enters the exhaust system and can ignite once it reaches the converter unlimited.

This can over-heat the converter unlimited far beyond its normal operating limit. and cause a Melt Down.

Possible causes are an improper fuel mixture, incorrect timing, bad spark plugs, a malfunctioning oxygen sensor, sticking float, defective fuel injector or a faulty check valve.

1. Two way converter unlimited : this is the much older type of converter unlimited. It carries out a dual function of oxidizing carbon monoxide to carbon dioxide and oxidation of hydrocarbon to carbon dioxide and water. This chemical reactions occur at the same time. Because of the inability of a two way converter unlimited to filter out oxides of nitrogen, they are no longer used in most countries today.
2. Three way oxidation reduction: this is the more advance type of converter unlimited. Here three different reactions happen simultaneously. The reactions are the reduction of nitrogen oxide to nitrigen and oxygen, the oxidation of carbon monoxide to carbon dioxide and conversion of hydrocarbons to carbon dioxide and water.
3. Diesel oxidation converter unlimited: this type is used on a diesel engine as the name implies. It makes use of the oxygen present in the exhaust to convert carbon monoxide to carbon dioxide and unburnt hydrocarbon to water and carbon dioxide

Where do the harmful gases come from

The engine  used in a car is known as an internal  combustion engine. This engine run on gasoline which are fractions of crude oil distillation. When the gasoline is burned with oxygen from the air in the engine, it produces water and carbon dioxide in the gaseous form. This is accompanied by other substances including toxic materials.

Harmful gases are also produced when we use leaded fuel in our cars. A bad  engine is also a culprit as it doesn’t burn the fuel efficiently, this causes unburnt substances to pass out of the exhaust. This is likely to happen as the engine experience wear and tear after along time of usage.

Why should I be concerned

Environmental impact of harmful substances released by the exhaust of vehicles are devastating. This toxic substances include hydrocarbons, carbon monoxide and nitrogen oxide. Hydrocarbons accumulation will produces smog as witnessed in large cities. Carbon monoxide is a poisonous gas that harms both humans and other animals while the nitrogen oxide causes acid rain and smog. This harmful substances are also thought to cause global warming in the long run. This is why the converter unlimited is employed to reduce emission of this substances.

How effective are converter unlimited

converter unlimited have proven to be highly effective in controlling toxic emission. Recent studies have shown that a car that has a converter unlimited installed will produces 87% less hydrocarbon, 85% less carbon monoxide and 62% less nitrous oxide in its entire life cycle.

The converter unlimited typically last for ten years but like other car components, this may not always be the case. There are a lot of factors that are responsible for the damage of aconverter unlimited . Generally, after 50, 000 miles of driving it will not be as effective as a new one and it is right to change it now. It is a durable component of the car that hardly gets damaged but if it eventually gets bad, it will lead to a sluggish engine performance or total shutdown. In an ideal situation, the converter unlimited is replaced only two times in a particular car.

Maintenance tips for your converter unlimited

• Avoid speeding through bumps and pot holes as they can potentially damage your converter unlimited . Remember they are installed under the car.
• Install an alarm system in your car, this will ensure your converter unlimited is not stolen from your vehicle.
• Other contaminate of a converter unlimited is the enggine coolant when it leaks into the combustion system. Always check to make sure the cylinder head is intact to prevent this leakage.
• Don’t use leaded fuel as this will make the converter unlimited inactive, thereby preventing it from working properly.

Final say: the converter unlimited is a durable component of the car, it will last as long as you maintain it. Because of the special elements it contains, it is a major target of car theft. Make sure you park in a good place and have your alarm switched on. Whenever you need to replace it, make sure you get a good one and also ensure it is properly installed.

converter unlimited in all modern vehicle exhaust systems

A converters unlimited will last for ten years or more on a routine basis if well maintained. The truth, however, is that they can become polluted, clogged, overheated, or physically damaged, resulting in slow engine output. Car engines need a lot of oxygen, which means that less air will enter the system if the exhaust flow is limited and efficiency suffers.

Because of excessive quantities of unburned gas caused by a misfiring spark plug or a leaky exhaust valve, converter unlimited may overheat. A malfunctioning oxygen sensor can also cause overheating. It may also be damaged by road debris or driving over a curb, like other parts of the exhaust system.

How a converter unlimited Works

The toxic gases created by the car’s engine pass through a converter unlimited after a vehicle is started. A honeycomb pattern composed of precious metals such as platinum, palladium, and rhodium consists of the converter unlimited’s internal structure.

The converter unlimited is usually built to operate at a high temperature of around 800 ° F. A chemical reaction occurs, resulting in safer components, such as oxygen, water, and carbon dioxide, coming from your mufflers.

Causes of a Bad converter unlimited

Most converter unlimited can last a vehicle’s lifetime, as described earlier. But a converter unlimited  can go wrong in some situations and needs to be replaced.

Almost all converter unlimited issues are due to a problem with the engine. It is most frequently caused by excess fuel entering the exhaust system owing to an inaccurate air/fuel combination, bad spark plugs, wrong engine timing, failed oxygen sensor, or other problems where fuel exits the engine’s combustion chamber unburned.

The converters unlimited reaches a temperature that is too high

h when this occurs and starts melting the inside or tearing the honeycomb material apart. This will then make the  converter unlimited from not working correctly.

Failed gaskets, lousy valve seals, or worn piston rings may also trigger oil or antifreeze to enter the exhaust system and coat thick carbon soot on the ceramic converter unlimited inside the converter unlimited .

If this is allowed to go on long enough, the converter unlimited would be clogged by these carbon deposits, so it can’t do its job. In this case, the exhaust flow is blocked entirely, and the backpressure builds back to the engine, which can cause overheating and other problems.

Lastly, there can be physical harm to the converter unlimited. Rocks, road debris, or potholes can get or break the outer shell of a converter unlimited or the hangers that protect it, but it’s not common.

Repairing a Bad converters unlimited

If you think you have a bad or clogged converter unlimited, you can remove the clog by adding a catalytic converter cleaner to your gas.

More than one use might be appropriate. Removing the cat and soaking it in a citric acid solution for 6-8 hours is an alternative and very sturdy way of cleaning a converter unlimited. Using sodium hydroxide is another choice.

If the catalytic converter is broken, including parts of the honeycomb breaking off inside, attempting some repair is not fee-sable, even though you can see some people claiming otherwise. Repairing it is your only choice in these situations.

How to Prevent the converters unlimited From Clogging

The chance of your  converter unlimited failing before it’s due will be reduced by having your exhaust, emissions, and combustion systems in the right conditions. The critical problems of acid rain and smog are these extremely hazardous substances, especially in low-lying valleys and critical metropolitan areas.

If you travel short distances with your car regularly, the hydrocarbons will not be burnt away because the converter unlimited does not get the chance to get hot enough. Try driving your car on the highway now and then for about 10 to 15 minutes to minimize the chances of getting a clogged converter unlimited.

To effectively burn off these hydrocarbon deposits, the requisite heat will be produced inside the converter unlimited, so it needs to run as efficiently as possible.

Final Words converters unlimited

A vital component of your car that needs to be maintained is the converter unlimited. Once the converter unlimited of your car goes terrible, other parts of your vehicle will be affected.

First of all let us tell a few raw prices of

converter unlimited

to answer the key question on the converter unlimited cost. After that we will have a detailed talk on pros and cons.

If the vehicle was produced before 80s then the converter unlimited will cost up to eight hundred dollars. The cost of aconverter unlimited  is about six hundred, but a labor cost will be added. So keep it in mind that the older is the car the bigger sum you have to spend to race old catalyst. Newer cars request even more money to replace converter unlimited which will go even further to 2500 dollars. If there is a chance to remove catalyst at home with proper tools, than there will be a way to save money, but sometimes there is no way to purchase converter unlimited if you are not authorized for it.

In a meanwhile, one might think that to remove catalyst means to harm the environment. On the other hand, this slightly increases power of motor, reduces fuel consumption, gets rid of regular alerts about problems. The fused or clogged converter unlimited leads to the fact that exhaust gases cannot go outside and return to combustion chamber. Combustible mixture that enters there becomes less efficient, and this negatively affects operation of motor.

Pros and Cons of converter unlimited removal with its following replacement

Why is it necessary to remove the converter unlimited?

Together with above mentioned dynamic characteristics of a car, as a bonus, the engine will become less sensitive to fuel quality, and you also eliminate the risk of ceramic dust getting inside the power plant. Old catalyst can be sold to recycling companies.

There are some negative consequences of converter unlimited removal:

• environmental factor;
• problems during car inspection;
• foul odor;
• extraneous sounds in exhaust system (if not removed correctly);
• errors on the display.

Consider important role of oxygen sensors cooperating with converter unlimited.

Their second name is lambda sensors. Usually they are installed in two places: one before and one after the converter unlimited. When the second sensor determines that the amount of harmful exhaust gases has increased to a critical level, it gives a signal that  converter unlimited has not worked or is functioning inefficient. Some modern car models in this situation may not start.

The second lambda sensor carefully monitors harmful emissions, and their allowable amount is regulated by the EU. These are standards known as “EURO” (Euro-2, Euro-3, Euro-4, Euro-5). The EURO-5 standard is currently in operation, its emission standards are up to 0.05 g / km, CO – up to 0.8 g / km and NO – up to 0.06 g / km.

When the exhaust system is without a converter unlimited, oxygen sensors will detect more harmful emissions. Accordingly, you need to make sure that you do not feel the absence of this important detail.

There are various ways to repair of converter unlimited:

in some cases, the repair of converter unlimited is carried out, according to regulations, to a new catalyst. We tried to briefly outline the main pros and cons of various types of repair of catalytic converters.

Diagnostics of converter unlimited. In many cases, correct diagnosis of a catalyst allows you to understand the real cause of breakdown and not just change the catalyst. Usually  converter unlimited error can catch fire literally from scratch. For example, a catalyst error can catch fire from damage or other part of exhaust system. It could just “shut down” the wiring or computer. Types of diagnostics that are offered: computer diagnostics (reading all errors and their analysis), endoscopy of catalytic converter (examination of the state of a catalyst), physical examination of exhaust system, measurement of purity of exhaust gases for compliance with EURO4, EURO5, EURO6 standards.

1. Replacing converter unlimited with a new one. If you need a replacement of a catalyst, then it is a due time to sell the old one. You can choose a catalyst that suits you with its cost and its properties. This repair path is undeniably most correct, but the most unreliable in the long term, because after two thousand kilometers converter unlimited will again need to be replaced. The main advantage is that exhaust gases will be clean.

2. Replacing the converter unlimited with a flame arrester. This procedure has two popular names, one of them is “replacing catalyst with a flame arrester,” and the other is “removing the catalyst”. In this case, you get rid of converter unlimited and everything that is connected with it. But having removed it you will gain following consequences: exhaust sound will become loud, exhaust system will easily burn out.

3. Rinsing, cleaning converter unlimited. In case of catalyst error has arisen due to the fact that the catalyst is clogged with combustion products, and this is the only reason why catalyst does not work. It is necessary to clean it and thereby remove any deposits. But if functional converter unlimited deposition layer has lost its properties, then this does not make sense, and replacement of catalyst by one of methods is required. Only diagnostics and inspection of the car can tell which is the best option for a catalytic converter.

Service stations, will carry out exhaust system diagnostics in order to 100% determine whether it is worth cutting out the catalyst or, possibly to clean it. It is difficult to determine the cause of failure yourself.

One way is to dismantle part of exhaust system, including the converter unlimited and remove contents of converter unlimited. Usually several holes with a diameter of 20 mm are made using a punch. This method has disadvantages: holes quickly become clogged again. But there are also positive aspects, since you do not have to cut metal and do welding.

Why one should remove and replace the converter unlimited?

If you need to cut out the converter unlimited , the price will depend on what you want to get on as a result. For those who are confused with a choice, experts can advise the best repair option.

Take a look at general figures and prices of a converter unlimited repair and replacement cost for some common vehicle models. Find a way to save money, selling your old converter unlimited to a specialized recycling organization and gain a good

Very often, car owners are faced with the fact that vibration is felt in a car cabin, and often this is due to the exhaust system. Almost all cars have parts or connections that compensate for the vibrations of the engine, respectively so that they are not transmitted to the exhaust system and car body. This is either a damper connection or a muffler. Any inexperienced driver can easily identify a malfunction in the exhaust pipe, often associated with a catalyst.

Signs of a clogged or destroyed converter unlimited malfunction

1. The car does not start or stalls instantly. The converter unlimited indicates a complete breakdown. Solution: Unscrew oxygen sensor (located in front of the converter unlimited). Start the engine, if the car is working, then the catalyst barrel is faulty. It needs to be replaced with a new one or an analog.
2. The car accelerates poorly and the engine picks up speed slowly. When driving, it seems that the car is being held from behind. So catalyst cells are partially clogged.
3. Fuel consumption has increased. This is also a symptom of a catalyst malfunction, but not always, it may indicate another malfunction, such as fuel injectors.
4. Exhaust comes out weakly from a pipe, honeycombs are clogged.
5. Exhaust has a bluish tint and a pungent, unpleasant smell. It means that the converter unlimited is destroyed or melted.
6. When accelerating, a metallic sound is heard (as if gravel was poured) – the catalyst is half destroyed, the block is clogged, or perhaps catalyst barrels have moved from a designated place.
7. “Check Engine” light comes on, low efficiency (code P0420). It may arise in case of other problems, but also signals a possible malfunction of aconverter unlimited .

How to diagnose a converter unlimited malfunction?

You can make sure that the catalyst is working on your own. In extreme cases, car services make paid diagnostics. Let’s highlight 3 main methods of checking the converter unlimited , which can cause different problems, including shaking.

When housing is deformed, converter unlimited honeycomb is likely to be damaged. In this case, an external examination will not give an understanding of contamination; it will be necessary to remove the catalytic converter from a vehicle.

The problem lies in a very difficult removal of a catalytic converter, it is not uncommon to “stick”, in which case it has to be cut off with a grinder. Having removed the converter unlimited, all the underparts of a car have to be carefully examined for gaps. If combs are clogged with dirt, they are cleaned or replaced with a new one. But the design does not always allow for an internal inspection without opening converter unlimited housing.

Clogged  converter unlimited symptoms

How does a clogged converter unlimited affect engine performance?

Contrary to various rumors, there are no eternal converter unlimiteds. This is the same part as many others, so it has its own operational life. How to check the converter unlimited, as well as what to do in case of breakdowns. It would seem that catalyst design is very simple. But in fact, it has its characteristics that you need to know. So, in its body, there are bobbins, which are most often ceramic and less often metal. Hazardous substances pass through the honeycomb of bobbins. But it is not the material of a converter unlimited that is responsible for clogging, but the noble metals that are deposited on a surface of bobbins. It’s about platinum and iridium.

During operation, the  converter unlimited may become hot enough to ignite. To prevent this from happening, there is a special heat-insulating layer inside the part. Exhausts are best neutralized at temperatures from three hundred degrees. And due to various processes, the converter unlimited  loses its performance after 100,000 km of the car’s path.

Signs of a clogged converter unlimited

Many diseases have their symptoms. Likewise, the converter unlimited has certain symptoms that indicate that something is wrong with it. When the service life of aconverter unlimited comes to an end, you can see the inscription “Check Engine” on an instrument scale, and the car will start working in emergency mode.

It is important to pay attention to the fact that the signal will light up instantly only if the part was physically damaged or electrical wiring was cut off. And therefore, the converter unlimited may stop correctly performing its tasks, but the lamp will still not burn.

As soon as the converter unlimited starts to fail, you will notice that car’s power has dropped sharply, and also that it has become much more difficult to start. It is almost always to blame for this clogging of a catalyst honeycomb with soot particles. As a result, the exhaust simply does not pass through the filter media. Gases that have not gone anywhere begin to put pressure on an engine. And it cannot endure such pressure for a long time, and therefore begins to fail.

Fails and car shaking can also occur when the filter coating of platinum and iridium has worn off. You can see that the flow of gases from a converter unlimited has become weak. And this will just mean that the period of validity has come to an end because under normal conditions emissions are large.

How to independently check the clogged converter unlimited?

If you do not plan to take the car to a service station for various reasons, you can check the efficiency of a converter unlimited yourself. And the first thing to do is to take a flashlight and shine into this part. If necessary and possible, you can remove the converter unlimited. But it often happens that it sticks to the base of a car. Better use the bracket to raise your car.

The second way to test the converter unlimited is to smell it. It can be completely atypical and unpleasant if the catalyst is out of order. And finally, the third method is to put your hand to the exhaust pipe. If the converter unlimited  is functioning properly, you will be able to experience a big exhaust emission. But if it is hammered, you will not notice any resistance.

What can be the main consequence of a clogged catalyst?

After all, it all depends on the strength of the breakage of your converter unlimited. So, if the converter unlimited is clogged with soot, it is enough to clean it so that it starts working correctly again. But if something more serious happened, consequences could be much worse. For example, if the inside of a part is melted, you will not be able to use the car. And the catalyst will have to be changed completely.

It is worth knowing about other even worse consequences. If gases do not pass through the device, they will return to the cylinder, but with particles of soot, ceramics, etc. A cylinder is a very fragile element of a car, and the smallest break can render the entire cylinder-piston system unusable. And if this happens to your car, then only the replacement of specific parts and the catalytic converter will help, which will be done at a service station.

Learning more about cars and spare parts, one may face names and terms, which can seem new or even unknown. A  converter unlimited in a vehicle or a car converter unlimited is an important part of the whole exhaust system. Its role is to serve to reduce the emission of harmful combustion products into the atmosphere. Talking about chemistry, the term catalyst is described as a substance, which can accelerate or cause a chemical reaction without participation in such a complex reaction itself. It is guaranteed by such substances as copper, nickel, gold, palladium, rhodium, chromium. The principle of operation of a car catalyst is precisely based on the ability of substances to accelerate the reaction. Most often, it is located immediately after the front pipe, but sometimes it is installed directly on a front pipe. They do this for faster warming up since it works effectively only at temperatures above 300 ° C.

If you check exhaust gases that come out of a crankcase of the engine of any car, you can observe a fairly high level of concentration of harmful chemical compounds that enter the environment and pollute it. It is to combat such emissions that a converter unlimited, or as it is also called, a car catalyst, was invented and designed. The main task of a catalyst is to oxidize hazardous harmful compounds, turning them into relatively safe for the environment. That Is why its presence in all vehicles is essential for health and nature.

Nowadays it is difficult to imagine any modern car, the exhaust system of which is not equipped with a converter unlimited even from an assembly line. Some people still do not imagine where it is located and how to find it by yourself. There are several ways to detect this car part if you know where to look. The converter unlimited car part is not that small to be lost, because its function is to reduce air pollution.

1. A converter unlimited as a part of a muffler

It should be noted that the  converter unlimited should be looked for in a muffler. It is designed to clean the exhaust, and therefore it is ALWAYS located at the beginning of a car muffler, where hot, often unburned gases come out. This catalyst is called upon to burn and clean gas, for this, it has a special mesh – a honeycomb structure, which is often made using noble metals.

2. converter unlimited next to the exhaust manifold

In 70% of cases, a simple and useful catalyst is located just behind an exhaust manifold, in the engine compartment of a car. That is, gases are collected from all 4 cylinders and enter the catalyst for cleaning. You will not confuse it with any muffler knee. The thing is that this is a thick “cistern”, surpassing other parts in size.

3.  converter unlimited is connected to a muffler

Such amount was dictated by the experience of operating cars. Previously, a common  was converter unlimited often attached under the bottom of a car, that is, not in the engine compartment, but under the bottom. However, protruding a large tank, the converter unlimited  was simply cut off! This item is not cheap, it’s not just a pipe or a resonator. Therefore, now almost all manufacturers are switching to fastening catalyst just next to the collector, it is more practical. Although, it is worth noting that some manufacturers still install catalysts under the bottom of a car. This is due to a narrow engine compartment.

If you open the hood, then you will not always be able to determine its location. Often the converter unlimited is covered with a protective metal casing so that there is just a sheet on top and catalyst is already under it. If you lift the car on lifts or drive into a hole, it is much easier to see it.

4. Catalyst sensors

Where are the sensors? Many people think that converter unlimited sensors are screwed into it! But this is wrong. There should not be sensors in a catalyst. But before and after the catalyst, two oxygen sensors are installed. The task is not only to measure the oxygen content before and after the catalyst but also to see excessive fuel consumption in a system. According to data from these sensors, the work of fuel supply can be automatically adjusted to avoid overflows.

Also, sensors signal catalyst failure. If the data before and after  converter unlimited does not differ much, this indicates that cleaning does not occur – perhaps “honeycomb” has collapsed or melted. This is where CHECK ENGINE error comes out.

Why it is better to leave the  converter unlimited where it is?

There are plenty of pros and cons for a catalyst here! Of negative aspects, one can be named: exhaust will come out directly without purification, and this is bad for the environment because every year environmental background only gets worse. Also, you will not pass control as converter unlimited measures CO emissions from the muffler. And if you remove this important car part from the system, then you need to flash the ECU, because oxygen sensors will just go crazy.

Do not try to change the structure of your vehicle or its parts. Every item Is created for its purpose, calculated by professional and experienced engineers. Just take care of your car and keep it clean and fresh day after day. This will guarantee a long and happy life for both the car owner and the vehicle.

The Waco Police Department issued a warning about the increase in catalytic converter thefts statewide.

Waco detectives were working on more than 100 active cases of catalytic converter thefts, according to their Facebook post.

Here’s some information on converter unlimited s and what to do if you become a victim.

Why would thieves target converter unlimited?

converter unlimited contain platinum, rhodium and palladium. The metals are expensive, and thieves sell the converters to scrap yards for $150 to $200 per piece depending on the size of the converter and the current rate on the metals inside it, according to The Spruce.

The rate of converter unlimited theft varies depending on the current prices of the metals inside it.

The price increase of the metals typically result in an increase in thefts.

Thieves often target taller vehicles like pickup trucks or SUVs because they can easily fit under the vehicle to access the converter unlimited, according to The Spruce.

How do you know if your converter unlimited was stolen?

It’s hard to tell if your converter unlimited was stolen just by looking at your vehicle. However, you’ll know when you start the engine.

Your vehicle may make a loud rumbling sound when you turn on the engine that gets louder when you hit the gas if your catalytic converter is missing, according to The Spruce.

“The exhaust is not working properly, so the vehicle also drives rougher than usual, often with a sense of sputtering as you change speed,” The Spruce said.

If you suspect your converter unlimited is stolen, go to the back of your vehicle and look underneath.

“The catalytic converter is a round canister that connects two pieces of piping in the exhaust. You will see a gaping space in the middle of your exhaust if the converter is missing, and you will likely see signs of the piping being cut away.”

Toxic fumes will likely be easy to smell without it, too, according to the Balance.

How can you prevent converter unlimited theft?

Try to make it a habit to park in well-lit areas.

Keep your car in a garage with the door closed when the vehicle is not in use if possible.

Parking close to a building entrance when parking in a public lot may also help prevent thefts as there is more pedestrian traffic in that area.

Remember that the location of your car may also be a factor.

If you are regularly parking in one area for a long period of time, such as a shopping mall or mass commuter parking lot, thieves have more time to access your vehicle and steal the , converter unlimited according to the Balance.

You can consider engraving your vehicle identification number (VIN) on the  converter unlimited which may help alert a scrap dealer that it was stolen and make it easier to identify the owner, according to The Spruce.

Another tip is to try calibrating your car’s alarm to set off when it detects vibration.

What do you do if your converter unlimited has been stolen?

If you are a victim of this type of theft, immediately notify the police department so the case can be documented.

If you have your VIN number engraved on the device, give them that number as well.

The Spruce recommends calling local scrap yards to inform them of the theft, especially if there is an engraved number on the converter that they can verify.

You can also give them your phone number so you are notified in case your converter unlimited shows up at a scrap shop.

converter unlimited appeared just in the first half of the 70s and, as you know, US automakers were at the forefront here for a while. Curiously, in addition to directly reducing the toxicity of exhaust, these converter unlimited have dragged along with the modernization of several areas of development of the automotive industry.

This was due to the very principle of their action, which, by the way, has not changed until now.

For some time

on different models, converter unlimited coexisted with carburetors or mechanical injection. For example, Chrysler, having burned itself with electronic fuel supply back in the 50s, was in no hurry to transfer its engines to it. But limiting norms for the content of various elements in the exhaust were approved by law.

It was necessary to somehow link the catalyst and the carburetor. Ecology is the engine of progress.

The metal barrel, located between the exhaust manifold and muffler-resonators, has a longitudinal honeycomb inside, where the surface is covered with a layer of a special substance, which is a converter unlimited.

Let’s just say that catalyst platinum with the addition of palladium is used as the latter, which converts harmful CO and CH into carbon dioxide and water. Such catalysts were called two-component, that is, capable of neutralizing only a couple of toxic components.

In 1977, rhodium was added, so that nitrogen oxide was transformed into a mono-element.converter unlimited have become three-component. So, this relatively simple chemical process proceeds without problems only under ideal laboratory conditions. In real operation, manufacturers are faced with the fact that the correct operation of converter unlimited and, in general, its resource is under constant threat.

As it turned out

the catalyst can properly work only when the ratio of the combustible mixture by air and fuel is in the proportion of 14.5–14.7: 1. Deviations to one side or the other reduce the conversion efficiency of CO and CH or NO.

The converter unlimited honeycomb structure with ultra-small cross-section tubes was chosen because this way it is possible to maximize the area on which the substance acting as a converter unlimited is applied. Accordingly, the volume of catalyst “processing” of exhaust gases is also growing.

To make the air-fuel mixture stable, carburetors began to be supplemented with electronic control. In 1975, in the United States, transistor ignition systems appeared, which minimized gaps in sparking, from which fuel burned out in catalyst.

We turned to the exhaust gas recirculation system

which, by lowering the combustion temperature of fuel mixture, reduces the number of nitrogen oxides. Finally, the fight for the environment, as well as the desire to remove more power, also contributed to the early introduction of electronic injection, a system that can fully unleash the potential ofconverter unlimited . At the same time, in the 70s, another event took place, under the influence of laws and public, oil producers abandoned additives based on tetraethyl lead.

And converter unlimited continued to be improved

. A quarter of a century ago, a keg moved from under the underside of a car into the engine compartment, right next to the exhaust manifold.

This was necessary for the catalyst fastest-warming up and reducing harmful emissions immediately after starting the car. The  converter unlimited substances begin to act only at 250-300 degrees. Later, the development of separate electric heating with a capacity of up to several kW was proposed.

There were systems of two catalysts

where the first was located directly in the path and worked while the main unit was warming up. Adsorption traps for hydrocarbons were set up, holding them until the  converter unlimited reached the operating temperature. Catalyst experiments have been and are being conducted with filler materials.

Refractory ceramics are relatively heavy and far from ideal for creating ultra-thin catalyst honeycombs. The metal for cells was used before, and now it is being used again, at a different technological level, using various bimetallic alloys. Lightweight, resistant to temperature, thin as foil, so you can significantly increase deposition area of ​​platinum, palladium, and rhodium.

Car owners try new options installing a universal catalyst

But universal catalyst, like the original, is highly dependent on external factors. It is impossible to give a full guarantee on it. Usually, they serve 60-80 t.km, but they can fail earlier if there is a failure in an ignition system or an engine operating system.

It is preferable to install a universal converter unlimited:

• If the car is under 5 years old;
• If you go through the inspection yourself;
• If you don’t want to pollute the atmosphere;
• If you are planning to travel abroad.

Limiting parameters of toxicity of exhaust gases are regulated by law in many countries by special organizations. For example, in the United States, this issue is controlled by the Department of Environmental Protection, and California has its department for overseeing air resources (California Air Resources Board). In Japan, the Ministry of Transport deals with the purity of the exhaust, in Europe it is a special European Commission.

As a rule

the degree of environmental concern directly depends on the economic and social level of the country’s development. Also, norms regulated by the law must be strictly implemented in practice.

That is why many  converter unlimited inventions had been implemented into the car item, responsible for cleaning the exhaust gas converter unlimited is usually combined with an exhaust manifold.

Such an arrangement of a former affects its efficiency, but makes assembly more expensive and can lead to damage to a piston group.

The lambda sensor

which determines the percentage of oxygen in the exhaust, and sends a signal to correct the mixture, appeared back in 1976. Then a sensor was added behind the catalyst, which monitors the quality of gas cleaning.

Bosch started measuring oxygen content back in 1968, but the first lambda sensor did not appear until eight years later – on the Volvo 240/260 for the North American market. A little later, other manufacturers also realized that without feedback from the control unit, the catalyst cannot provide maximum efficiency.

Get rid of soot!

In the early 2000s, it was the turn of diesel engines. They, equipped with already familiar catalysts, began to be equipped with diesel particulate filters. The fact is that the temperature of exhaust gases in no-load modes is lower here than in gasoline engines.

It is not enough for complete combustion of carbon, so particulate matter or soot is obtained, which can pass through the catalyst.

The particulate filter is located in front of the converter unlimited . It also has platinum and the same honeycomb channels. Only the latter are staggered and are divided into inlet and outlet.

And between them

there are partition converter unlimited filters that contain solid particles with nitrogen oxides. It seems to be the same filter, but with a fundamental difference. It does not accumulate solid particles. converter unlimited filter burns them out with the help of oxygen released from nitrogen oxides and an additional nozzle that supplies diesel fuel to the unit.

This complicated but small automotive part plays a huge role in cleaning the environment. Take care of your converter unlimited!

converter unlimited is part of the exhaust system and is located in the immediate vicinity of a vehicle’s exhaust manifold. Catalyst enters into that incandescent exhaust manifold, and after that, significantly slowed down, cooled and cleaned of harmful substances, it appears in a resonator and in a muffler.

The principle of operation of a converter unlimited is based on chemical reactions that neutralize harmful emissions of nitrogen oxide, carbon, and all kinds of hydrocarbon groups. The main element of a catalyst is made in a form of a massive ceramic or metal block with small honeycombs, on walls of which precious metals are applied: an alloy of iridium and platinum, as well as rhodium and palladium.

When touching chemically active surfaces

harmful compounds are burned and removed from the exhaust pipe in the form of harmless N2 and CO2. Platinum and palladium act as oxidants in a converter unlimited and greatly accelerate the combustion of hydrocarbons. The active element is placed in a metal casing and provided with a layer of thermal insulation.

converter unlimited not only traps and neutralizes harmful compounds but also directly affects the operation of an engine. Signals from sensors located at the input and output of a  converter unlimited are constantly read by the “brains” of a car and help to optimize working mixture in the best way. It is better to know in advance all possible reasons for a malfunction to avoid engine and vehicle damage.

converter unlimited malfunction symptoms

The service life of an expensive  converter unlimited is usually about the same as the service life of the entire car, but it often breaks down much faster than it should be and can pull the engine with it. It is important to remember that a  converter unlimited does not fail for no reason. Its breakdown is a sign of improper operation of the ignition system, incomplete combustion of a mixture in cylinders, severe engine wear, or prolonged use of low-quality fuel.

You can understand that your converter unlimited is being scrapped by several characteristic symptoms:

– the decrease in motor performance;

The most common symptom of a converter unlimited failure is a severe decrease in engine power. The car starts to lose momentum and accelerates poorly. Engine runs unstable, overheats, and stops. This happens when the throughput of a catalyst is greatly reduced: the honeycomb is destroyed, melted and sintered, clogging the hole and interfering with the free passage of exhaust gases. At the initial stage of such converter unlimited  malfunction, the car will accelerate to a relatively low speed, the engine starts hard, and then “suffocate” and stall. Fuel efficiency also deteriorates markedly. Also, during a cold start, a strong unpleasant odor appears.

– rumble under the bottom;

A loud rumble under the underside of a car indicates that the active element of a  converter unlimited has begun to deteriorate and fall apart. Ceramic catalyst fragments affected by exhaust gas flow randomly beat against walls of a casing and create an unpleasant rumble. As a rule, this is most clearly manifested at increased engine speeds and during start-up.

– low pressure of exhaust gases from a muffler

If you bring your hand to an exhaust pipe, you can feel a pulsation. Exhaust valves of cylinders work alternately. If the exhaust flow is even and constant at idle, this is a sure sign of a clogged catalyst. If you increase the speed and then turn off the engine, exhaust gases will continue to build up pressure for a short time, gases accumulated in the clogged converter unlimited pipe come out.

– activation of Check Engine icon on a dashboard

The most common symptom of a catalyst failure is a system error that activates the engine trouble icon on a dashboard. If this symptom appears, you need to immediately read the error code with a diagnostic scanner and fix the problem. If car “brains” detects incorrect readings on oxygen sensors, they immediately notify the driver of this, and at the same time put the engine control system into emergency mode. This is often accompanied by a deterioration in dynamics and increased fuel consumption. Computer diagnostics in this case often detects errors P0420 (low catalyst throughput) or P0430.

Causes and consequences of  converter unlimited failure for the engine

Failure of a  converter unlimited does not occur suddenly and without reason. With the correct operation of all other systems, it faithfully serves for many years until the moment the vehicle is scrapped (and often survives it). If the  breaks down on your car, melts, or crumbles, you will almost certainly have to diagnose and repair the ignition or power system.

As a rule, the converter unlimited is damaged precisely due to the incorrect operation of these two systems. With a faulty ignition system, fuel in one or more cylinders does not burn out completely but enters the exhaust system. The second catalyst is forced to burn off increased volumes of hydrocarbons, which heat the honeycomb to ultra-high temperatures, which leads to their sintering. Spark plugs, coils, or high-voltage wires can cause major trouble. A malfunction of injectors, which begin to pour fuel, leads to similar breakdowns. Worn or stuck oil scraper rings of cylinder-piston group or failure of oil scraper seals lead to the same result, only engine oil burns out in a converter unlimited.

Another common cause of converter unlimited failure is severe mechanical damage leading to the deformation of the housing. It is important to remember that thin-walled combs can easily crumble even with minor physical exertion. Leaving off-road, it will be useful to attend to the installation of additional protection for underbody as well as your car  converter unlimited .

Failure to repair the converter unlimited is dangerous because small particles of ceramics can get through the exhaust tract straight into the engine cylinders. Once there, they instantly scratch the cylinder walls and completely disable the engine. Suffering from ceramic debris and turbine (if any). Additional heating of the exhaust tract leads to deformations of the cylinder head and greatly reduces the resource of a power unit.

To avoid critical breakdown, do not bring your car to a deplorable state and fix the converter unlimited malfunction in time. Fortunately, it is quite possible to do this even on your own.

Car converter unlimited is designed to neutralize harmful car exhausts and is part of exhaust system.

A converter unlimited is an element of an engine exhaust system designed to clean exhaust gases before they are released into the atmosphere. The need to develop this automobile motor assembly arose in 60s of the last century, when the world community was concerned about the state of ecology on our planet. At that time, the level of emissions from automobile exhaust pipes was not established at legislative level.

The first standards for content of toxic products in car emissions were introduced in 1970s. Auto producers were required to equip cars with devices that reduce volume of carbon monoxide and products of combustion of hydrocarbons. Since 1975, catalyst has become an indispensable part of all cars coming off the assembly line.

Manufacturers install three types of converter unlimited on cars:

1. Ceramic item use a mechanical method of cleaning exhaust gases. It consist of ceramic plates coated with precious metals.
2. Maximum resource of this type of work is 100 thousand kilometers. However, with poor fuel quality, its replacement is required after 70–80 thousand kilometers.
3. Metal converter unlimited has another construction. Its filling consists of metal honeycombs with increased elasticity. The design of such parts is reliable and more durable than ceramic converter unlimited.
4. Sports converter unlimited is considered to be the most reliable model. But at the same time it has a high cost. Made of metal it has greater bandwidth than the two previous options.

What does catalyst consist of and how it works?

converter unlimited device has ceramic honeycombs in its basis

Structurally, converter unlimited  is a ceramic substrate made in the form of honeycombs, inserted into a metal housing and protected by heat-insulating materials. Small cells of a catalyst have a special coating or working composition.

The honeycomb composition is an alloy of platinum, rhodium and palladium, precious metals, the cost of which exceeds gold at least twice. The honeycomb structure of converter unlimited increases the contact area of ​​toxic gases with neutralizing surface. Remains of harmful substances instantly burn out and do not enter in atmosphere.

The converter unlimited consists of the following parts:

• Housing with inlet and outlet nozzles;
• Ceramic block with porous structure;
• Catalytic layer, spraying on cells of a ceramic block;
• Sensor (lambda sensor) is a device that shows the pollution of gases after cleaning;
• Metal casing performs the function of thermal insulation and protects housing from mechanical damage.

converter unlimited circuit is installed after the exhaust pipe of an engine or in exhaust manifold. This arrangement is necessary for effective operation of a converter unlimited, since neutralization of toxic substances is possible only at high temperatures. The operation of a node is as follows:

Exhaust gases are sent through the inlet to the inside and enter ceramic block, filling the cells.

converter unlimitedmetals oxidize unburned hydrocarbons and carbon monoxide. Reducing metal, rhodium, neutralizes nitric oxide and turns it into a harmless substance. Pure gas is discharged into atmosphere through the outlet pipe.

It is important! The decisive role in the process of neutralizing toxic substances is played by the temperature. Conversion is possible at temperatures from 300 degrees, but basically the working temperature of a  converter unlimited is in a range from 400 to 800 degrees.

At the time of engine warm-up, converter unlimited is inactive, and this is a significant drawback of models developed to date.

Difficulty in organizing correct operation of the unit is danger of its overheating. If you place converter unlimited closer to an engine, service life will decrease dramatically due to systematic overheating. Most car manufacturers place the part in an area of a right front wheel, where it is possible to maintain the temperature at optimum level.

Nowadays in the vastness of network

you can find many tips where motorists offer their less experienced colleagues to cut off the converter unlimited on a car.

It’s time to figure out why this element of design was so annoying for some drivers,

and why in fact it should be left in its place.The first and most important thing why unfortunate converter unlimited is so annoying for many motorists is its cost.

And everything because the catalyst uses expensive platinum. That is why few people want to spend huge amounts on replacing catalyst.

As a result, many drivers simply decide to remove the part, and install a flame extinguisher on its place in the muffler.

On the one hand

this move is cunning and even somewhat reasonable (a slight increase in power).

because if nothing is done with problematic element immediately, then it will be worse. On the other hand, it’s better not to do this at all.

Firstly

it is necessary to clarify a simple truth that a car without converter unlimited becomes much “dirtier”.

Of course, some kind of ecology doesn’t concern most people. If so, then it is worth considering that without a converter unlimited the car will start to smell worse.

Secondly

installation of a substitute on lambda sensor violates correction of composition of air-fuel mixture.

Incorrect operation of engine leads to increase in fuel consumption, a large amount of soot is forme in combustion chamber.

This, in turn, is fraught with numerous negative consequences not only for the unit itself, but also for other nodes.

Thirdly

the removal of catalyst from exhaust system and installation of a substitute on some models lead to increased consumption of engine oil.

And this, after all, is an additional expense in the long run. Thus,

it is quite obvious that it is better to spend money on a new converter unlimited once than to deal with numerous problems after a while.

One common consequence of  converter unlimited removal is increased oil consumption.

This phenomenon does not occur on all engines, but on the web you can find many stories of car owners who faced a similar problem.

There are many speculations about reasons. The most realistic is reduction of back pressure in exhaust system.

converter unlimited creates a back pressure, due to which the oil scraper rings correctly do their job. But without a design on some cars, situation is changing.

Let us look the list of models on which there is an increased oil consumption after removal of a converter unlimited

• Entire line of Gamma engines from Kia / Hyundai. After removing the converter unlimited, oil consumption on a serviceable engine can reach 1.5 liters per 10,000 km.
• On the other hand, it is also dangerous to leave the catalyst, because until 2016 there was a problem with its destruction and
• ceramic dust getting inside the power unit. Someone is at risk, and someone prefers to add oil.
• Volvo cars with the B6324S engine (3.2 liters). After removal of catalysts, car owners are faced with a consumption of engine oil of 1 liter per 1,000 km.
• At the same time, the piston group is in a normal state for its mileage.
• Japanese engine 3MZFE suffers from a similar problem, which can be found on Toyota and Lexus mid-zero years. The consumption of engine oil after removal of converter unlimited also reaches 1 liter per 1,000 kilometers.

converter unlimited removal procedure should be carefully monitore

Existence of dust in an exhaust system before its installation is inadmissible, otherwise solid particles can get into cylinders.

It is recommende to install a flame arrester that is suitable for a specific engine.

will create a sufficient level of back pressure, which will ensure minimum consumption of engine oil after removal of the converter unlimited.

Failure of a converter unlimited does not occur suddenly and without reason.

With the correct operation of all other systems, it faithfully serves for many years until the moment the vehicle is scrappe (and often survives it).

If the converter unlimited breaks down on your car, melts, or crumbles, you will almost certainly have to diagnose and repair the ignition or power system.

As a rule, the converter unlimited is damage precisely due to the incorrect operation of these two systems.

a faulty ignition system, fuel in one or more cylinders does not burn out completely but enters the exhaust system. The second converter unlimited is force to burn off increase volumes of hydrocarbons,  which leads to their sintering. Spark plugs, coils, or high-voltage wires can cause major trouble.

A malfunction of injectors, which begin to pour fuel, leads to similar breakdowns.

Another common cause of converter unlimited failure is severe mechanical damage leading to the deformation of the housing. It is important to remember that thin-walled combs can easily crumble even with minor physical exertion. Leaving off-road, it will be useful to attend to the installation of additional protection for underbody as well as your car converter unlimited.

Failure to repair the converter unlimited is dangerous because small particles of ceramics can get through the exhaust tract straight into the engine cylinders.

Once there, they instantly scratch the cylinder walls and completely disable the engine. Suffering from ceramic debris and turbine (if any).

Additional heating of the exhaust tract leads to deformations of the cylinder head and greatly reduces the resource of a power unit.

To avoid critical breakdown, do not bring your car to a deplorable state and fix the converter unlimited malfunction in time. Fortunately, it is quite possible to do this even on your own.

 activation of Check Engine icon on a dashboard

The most common symptom of a converter unlimited failure is a system error that activates the engine trouble icon on a dashboard.

If this symptom appears, you need to immediately read the error code with a diagnostic scanner and fix the problem. If car “brains” detects incorrect readings on oxygen sensors,

they immediately notify the driver of this, and at the same time put the engine control system into emergency mode. This is often accompanied by a deterioration in dynamics and increased fuel consumption. Computer diagnostics in this case often detects errors P0420 (low catalyst throughput) or P0430.

converter unlimited engine is part of the exhaust system and is located in the immediate vicinity of a vehicle’s exhaust manifold.

converter unlimited enters into that incandescent exhaust manifold, and after that, significantly slowed down,

cooled and cleaned of harmful substances, it appears in a resonator and in a muffler.

The principle of operation of a catalyst is based on chemical reactions that neutralize harmful emissions of nitrogen oxide, carbon,

and all kinds of hydrocarbon groups.

main element of a converter unlimited

The main element of a converter unlimited is made in a form of a massive ceramic or metal block with small honeycombs,

on walls of which precious metals are applie:

an alloy of iridium and platinum, as well as rhodium and palladium.

When touching chemically active surfaces, harmful compounds are burne and remove from the exhaust pipe in the form of harmless N2 and CO2.

Platinum and palladium act as oxidants in a catalyst and greatly accelerate the combustion of hydrocarbons.

The active element is place in a metal casing and provide with a layer of thermal insulation.

converter unlimite not only traps and neutralizes harmful compounds but also directly affects the operation of an engine.

Signals from sensors locate at the input and output of a catalyst are constantly read by the “brains” of a car and help to optimize working mixture in the best way.

It is better to know in advance all possible reasons for a malfunction to avoid engine and vehicle damage.

converter unlimited malfunction symptoms

The service life of an expensive converter unlimited is usually about the same as the service life of the entire car,

but it often breaks down much faster than it should be and can pull the engine with it.

It is important to remember that a converter unlimited does not fail for no reason.

Its breakdown is a sign of improper operation of the ignition system, incomplete combustion of a mixture in cylinders, severe engine wear, or prolonged use of low-quality fuel.

You can understand that your converter unlimite is being scrappe by several characteristic symptoms:

– the decrease in motor performance;

The most common symptom of a catalyst failure is a severe decrease in engine power. The car starts to lose momentum and accelerates poorly.

Engine runs unstable, overheats, and stops. This happens when the throughput of a converter unlimite is greatly reduced:

the honeycomb is destroye, melte and sintere, clogging the hole and interfering with the free passage of exhaust gases.

At the initial stage of such converter unlimited malfunction, the car will accelerate to a relatively low speed, the engine starts hard,

and then “suffocate” and stall. Fuel efficiency also deteriorates markedly. Also, during a cold start, a strong unpleasant odor appears.

– rumble under the bottom;

A loud rumble under the underside of a car indicates that the active element of a catalyst has begun to deteriorate and fall apart.

Ceramic converter unlimited fragments affected by exhaust gas flow randomly beat against walls of a casing and create an unpleasant rumble.

As a rule, this is most clearly manifested at increased engine speeds and during start-up.

– low pressure of exhaust gases from a muffler

If you bring your hand to an exhaust pipe, you can feel a pulsation. Exhaust valves of cylinders work alternately.

If the exhaust flow is even and constant at idle, this is a sure sign of a clogged converter unlimited.

If you increase the speed and then turn off the engine, exhaust gases will continue to build up pressure for a short time,

gases accumulated in the clogged converter unlimited pipe come out.

Platinum, rhodium, palladium and even gold can act as a perfect  the converters unlimited. Without them, the process would have been impossible.The entire filling of the  converter unlimited looks like a layer of precious metals deposited on ceramic honeycomb. And the converter unlimited is not only a unit, but also a housing, and lambda sensors, and a heat insulator casing.It is the ceramic block that is the converter unlimited of the reaction, and not the entire item assembly that is “dusting” into the cylinders, so they usually talk about removing the catalytic converter, sometimes replacing it with other parts.

The first converter unlimited was install in 1975. But there were no big problems from them then, and until recently no one could have thought that the catalytic converter could cause scuffing and oil scrapes. The converter unlimited was located far from the cylinder block, in the exhaust system somewhere under the bottom of the car. Yes, the converter unlimited can die there too: clog up and fall apart. And this is very important for all car owners, not only unique vehicle fans.

The suffering is insignificant: the car pulls worse, but the motor remains intact. The error of the lambda sensors that do not understand what is happening with the amount of oxygen can also be annoying. The solution to the problem is elementary, a converter unlimited is change.

The situation become much worse when a converter unlimited was place close to the unit. In case of destruction of the base, ceramic dust begin to enter the cylinders. There are still people who are convince that dust from the exhaust can not get into the intake.

When the converter unlimited needs to be replaced

Engineers under the guarantee are partly to blame for the disbelief in the possibility of ceramic dust entering cylinders. They at one time convinced the victims of a converter unlimited  that the destruction of this wonderful element could not happen. Although, at the same time, the guarantee for the converter unlimited was only a thousand kilometers, and it was proposed to change the killed engine at your own expense. Ceramic dust can get into the cylinders.

Pay attention to this essential vehicle part, because there is nothing to do when the converter unlimited  has to be changed. Cleaning the  converter unlimited will help to prolong the life of your car and motor itself without much time and efforts.

A ceramic converter unlimited will eventually fail on any vehicle. But the danger is primarily those that stand on the exhaust manifold at a distance of 15-20 cm from the cylinder head. In addition, there are motors, where the  converter unlimited was installed in the exhaust manifold, built directly into the cylinder head. Over time, there are more and more motors with collectors and the problem is more and more widespread.

converter unlimited failure: causes and consequences

The converter unlimited turns out to be really clogged to a brick state. It is removed, ideally with a firmware correction. And the car starts to go. And after a while, its owner returns with a complaint about the oil consumption that has appeared. In most cases, the reason is very simple: the ceramic chips have already got into the engine and have done their dirty work.

The driver of the car must control the converter unlimited by himself if it is possible, as the engine power depends on it. A dirty device will result in increased fuel consumption and reduced vehicle dynamics. which can be done even in the garage or in a car service. Importance of this device for a car is essential not only for nature, but for laws of different countries. Strict rules request many vehicle control services.

The engine has to respond better to the gas pedal. And the oil consumption of a scuffed engine is very dependent on the crankshaft speed. So there is a feeling that the “oil grub” appeared just after the removal of the converter unlimited. Although almost always it was in this case before: the piston was already ruine by dust.

converter unlimited removing

remove converter unlimited after it is already severely damage. It is worth checking cylinders with an endoscope. If there are bullies, active driving will only increase the already existing oil consumption. In addition, the present oil burner itself is capable of killing a normal  converter unlimited. The oil mist with additives will clog it quickly enough due to an increase in pressure in the crankcase. In this case, the increase in oil consumption with the removal of the converter unlimited is very, very indirect. But there is a situation when the oil burner starts precisely because of the

The cost of a metallic converter unlimited is much lower than that of ceramic (almost 2.5 times).

Although new metal converter unlimited themselves are more expensive than ceramic ones, there are much less precious metals.

It is also taken into account that the processing of such a converter unlimited is a more laborious and costly process

Since it is sometimes impossible to visually determine the conditions of a converter unlimited and it’s size, if it is also broken, it is better to use spectral and chemical analysis.

If a used converter unlimited is sold in a tank

then the price can be determined by the corresponding marking on the body. Sometimes evaluation is made by photographs or by phone, but this service is offered exclusively to regular customers.

The final cost of the used automobile converter unlimited is calculated after spectral and chemical analyzes, only this way makes it possible to determine the exact content of precious metals in the catalytic converter.

The high cost of used converter unlimited is explained by the fact that precious and rare metals of the palladium and platinum groups are used for their production.

If you need to replace the converter unlimited on a car, do not throw away the old one, sell the used converter unlimited to get a payment.

This will save money before purchasing the new device and it will cost you less. Plus, you show that you care about the environment.

Common malfunctions of a converter unlimited can occur due to exposure to high temperatures over 1000 degrees and chemical reactions. As a result, the part can burn out or melt.

The second most popular reason is low-quality fuel, which cannot burn completely.

It burns out in the collector or the unit itself, clogging cells and making it difficult for air to pass. A similar situation can happen with high oil consumption in the engine, which can also actively contaminate filters.

The presence of problems in the operation of a car converter unlimited can be determined even just looking at it.

If the body of the part is deformed, there is a high chance that it is damaged. At the same time, it will not be possible to inspect the device from the outside for clogging with dirt and combustion products.

You will need to remove the clogged converter unlimited.

If there is an initial stage of wea

without damage or contamination of cells and the converter unlimited is not deforme or melted,

it can be sold to a specialize company getting a good profit.

Basic price is the following: ceramics – up to 600 EUR/kg,

particulate filter (PDF) – up to 300 EUR/kg, metallic foil – up to 70 EUR/kg.

A converter unlimited is one of the main elements of the exhaust system

, performing the function of reducing the emission of harmful substances and exhaust gases into the atmosphere. It is usually installed on both gasoline and diesel power plants in close proximity to the exhaust manifold or muffler.

The converter unlimited is subject to mandatory disposal, which is a complicated process that requires special equipment. The purchase of a converter unlimited has been carried out almost everywhere.

The cost of every used car converter unlimited depends on:

• Type of device (metal or ceramic);
• Countries of origin (Germany, France, USA, Japan or China, RF);
• Car model, engine size, year of manufacture, country of assembly or where it was exported;
• From size: cut from the body, whole or broken, shredded;
• On the purity, degree of contamination of the delivered mass: with asbestos, cotton wool or without;
• From exchange quotations of prices for metals Pt, Pd, Rh and from exchange rates;
• Weights, there are catalytic converters which weight is only 100 grams;
• Duration of operation and its intensity, up to 150 tons of 1/3 of the original;
• On the quality and type of fuel. For example, on gas for 2 years and as a result it is almost empty.
• The price of the first  converter unlimited is higher than all subsequent ones, even if they are in the same housing, with the exception of Subaru, on the contrary, the latter is more expensive.

Auto producers are creating more and more sophisticated vehicles to comply with environmental laws. A  converter unlimited is a gadget of a vehicle, pointed toward lessening harmful emissions into the environment by diminishing NO and afterburning CO. Most of all precious metals are contained in a ceramic  converter unlimited from German cars, such as Opel, BMW, Mercedes, Audi, Volkswagen.

The cost for converter unlimited will be approximately one hundred and twenty percent of the average indicated, but it should be taken into account that the converter unlimited  from cars released after 2000 will differ significantly in price from the car manufactured before 1997. It should also be taken into account that there is a catalytic converter with a predominance of platinum and a predominance of palladium.

Next in the price range are car  converter unlimited from Japanese cars like Nissan, Toyota, Mazda, Honda.

Their cost ranges from seventy five one hundred and ten percent, followed by the cars of French automakers, the cost of their catalytic converter is seventy to ninety five percent of the nominal.

Then, according to the cost there are American cars with sixty to ninety percent, “Koreans” – sixty-eighty five %. The cheapest used car catalytic converters are from Russian-made cars, unless, of course, this is an export option.

Yes, you can drive without a converter unlimited, but you need to approach everything with your head

If you do not want your car to be repaired, then first you need to make sure that removing the converter unlimited is the best way for you.

It is normal also for a thief to pay special attention when selling a converter unlimited.

Their scope is to sell them at the highest cost.

This is important also for a car owner, when you need to change a converter unlimited.

You can calculate the approximate cost of catalyst processing on our website on the Calculator Page.

A spot that has vast experience in purchasing a converter unlimited  is the best in the event that you need to sell it.

What can happen if you drive without a converter unlimited ?

There will be more caustic smoke, noise, environmental damage.

Many argue that driving without a converter unlimited will not lead to anything.

This is an erroneous opinion,

because our exhaust system service already has dozens of cars with burned-out exhaust systems due to the lack of a converter unlimited.

The burnt exhaust system is the first and most frequent thing that happens when driving without a converter unlimited.

No matter how expensive your car is, all stock exhaust systems are made from the same steel, and they are not good at all.

You can drive without aconverter unlimited if you have an engine up to 50 HP.

It may not burn out, but are there still such cars.

If you drive without a catalyst, then you will have to change the exhaust in a year or a year

and a half, and this is completely different money, even in comparison with installing the original converter unlimited.

Traffic fumes without a converter unlimited will be very caustic.

People in a car can be easily poisoned if you stand in a traffic jam and open a window with a favorable wind.

converter unlimited thereby deactivates the most dangerous components and chemical compounds in gases, so that you can drive safely.

A backward wave of gases will not get into the engine of your car.

Sound of the exhaust system will change,

it will become more severe and loud. The presence of a catalytic converter can soften the sound.

But its main function is to extinguish high temperatures,

unfortunately the only way to get rid of the car noise is to install additional mufflers if you are going to drive without a  converter unlimited

. And if you like the noise of a car, and you want to highlight it, you can put a resonator instead of a converter unlimited and the sound will become much brighter!

Search for a recycling company in the Buyers Catalog that will purchase your  converter unlimited at the best cost.

Talking about the causes which affect the price of aconverter unlimited , it is better to mention general ones. The sales market is one of the biggest influencers. Better converter unlimited are provided for the European car market, and if you need to sell a car catalyst, originally intended for third world countries, then they will not give a high price for it.

The quality of the converter unlimited will also depend on the class of vehicle it is installed on. High mileage and long-term operation negatively affect converter unlimited and therefore are not very optimistic about their value.

As you know

the converter unlimited has the property of “emptying”, and therefore a sporty driving style will make it cheaper. If certain additives are present in gasoline or other fuels, then over time the precious metals will be washed out.

Usually the composition of a car  converter unlimited initially contained Pt, Pd, and Rh. With time and modernization, the contents can change, but the idea and process of purification remain the same.

One ton of ceramic  converter

unlimitedcontains about one thousand and five hundred ppm of Pt, almost one thousand ppm of Pd, and about three hundred ppm of Rh. Diesel converter unlimited  or premium cars contain Pt and Rh. Although their metal contents are about 2.5-3.5 thousand ppm. In general, the acceptance of catalytic converters with similar content is about seventy percent.

The cost of such parts of the exhaust system on average varies between sixty to seventy-five USD per 1 kg. This type of  converter unlimited can be attributed to an endangered species, and according to some sources, the average price for it is up to eighty USD per 1 kg. Considering these simple figures one can understand the price of the scrap item. Calculate it by yourself and discover benefits from selling. Profit from a great deal with one of your local recycling stations.

Myths about scrap converter unlimited prices

Let us look at several myths about scrap converter unlimited prices and how to decide what is right and what is wrong. The first one is that diesel is always more expensive than gasoline converter unlimited.

When evaluating a converter unlimited do not rely on the type of engine. In modern diesel cars, a particulate filter is used and converter unlimited are installed on all power units, both gasoline, and diesel. It is better to pay attention to the year of manufacture and the class of the car. The second myth is that old  are more expensive than new ones.

It is a new item that contains more precious metals

. And last, but not least is that European converter unlimited are more expensive than others. This is also a wrong judgment because the highest price for buying converter unlimited will be not only for a high-quality European converter unlimited but also for their Japanese counterparts.

It is common that all  converter unlimited have sequential numbers, and this is something that can be utilized to decide the purchasing cost. Experienced organizations will request the sequential number of your item before providing the cost estimate tag.

Protect your car and drive safely to earn on scrap converter unlimited!

The sum you get will be of great help when it comes to repairing the converter unlimited. More and more companies offer to recycle old converter unlimited and looking around attentively, you can find your best partner.

Modern motorists have an excellent opportunity to get rid of a faulty converter unlimited when and where they want to do it. Usually, there are plenty of car service stations that are ready to give some information on purchasing old catalysts.

Specialized companies always buy used converter unlimited in any quantity and offer good deals, both to individuals and large suppliers. Now you can sell converter unlimited, the price for the device will be high, and the operating conditions are usually transparent.

The purchase of catalytic converters is equal for both foreign and domestic manufacturers in any condition. You can calculate the cost of a scrap catalytic converter using a special calculator or simply by calling consultants. It is not only a profitable but also a satisfying process, due to your will to recycle the old item.

In which cases should the  converter unlimited be sold

Is it really necessary to consider mileage and driving conditions? Should everyone follow a producer’s manual? Which signs can help to understand the vehicle problem? These questions and many others are usually concentrated in the heads of modern drivers, thinking of their car maintenance cost.

A  converter unlimited malfunction is indicated by the power unit decreasing in its work. It is easy to perceive because of some distinctive features.

This occurs when the honeycomb structure melts or becomes clogged with soot and exhaust gases are difficult to escape. An additional booming or rattling sound indicates the destruction of the car’s ceramic of a converter unlimited. Excessive smoke with an unpleasant smell comes out of the exhaust pipe in case of a failure.

Processing is a basic need for individuals who need to discard or improve the working of their exhaust systems. The best spot for this is to find scrap vendors.

They are the best companies to sell or reuse your converter unlimited. It is always better to collect more information on prices and possibilities to recycle a converter unlimited.

First of all let us tell a few raw prices of converter unlimited to answer the key question on the converter unlimited cost.

After that we will have a detailed talk on pros and cons

If the vehicle was produed before 80s then the converter unlimited will cost up to eight hundred dollars. The cost of a converter unlimited is about six hundred, but a labor cost will be added.

So keep it in mind that the older is the car the bigger sum you have to spend to race old catalyst.

Newer cars request even more money to replace converter unlimited , which will go even further to 2500 dollars. If there is a chance to remove converter unlimited at home with proper tools, than there will be a way to save money, but sometimes there is no way to purchase a converter unlimited if you are not authorized for it.

In a meanwhile, one might think that to remove converter unlimited  means to harm the environment.

On the other hand, this slightly increases power of motor, reduces fuel consumption, gets rid of regular alerts about problems. The fused or cloggedconverter unlimited  leads to the fact that exhaust gases cannot go outside and return to combustion chamber.

Combustible mixture that enters there becomes less efficient, and this negatively affects operation of motor.

Pros and Cons of converter unlimited removal with its following replacement

Why is it necessary to remove the converter unlimited Together with above mentioned dynamic characteristics of a car, as a bonus, the engine will become less sensitive to fuel quality, and you also eliminate the risk of ceramic dust getting inside the power plant. Old converter unlimited can be sold to recycling companies.

There are some negative consequences of converter unlimited removal:

• environmental factor;
• problems during car inspection;
• foul odor;
• extraneous sounds in exhaust system (if not removed correctly);
• errors on the display.

Consider important role of oxygen sensors cooperating with converter unlimited .

Their second name is lambda sensors. Usually they are installed in two places: one before and one after the converter unlimited.

When the second sensor determines that the amount of harmful exhaust gases has increased to a critical level, it gives a signal that  converter unlimited has not worked or is functioning inefficient. Some modern car models in this situation may not start.

The second lambda sensor carefully monitors harmful emissions, and their allowable amount is regulated by the EU.

These are standards known as “EURO” (Euro-2, Euro-3, Euro-4, Euro-5). The EURO-5 standard is currently in operation, its emission standards are up to 0.05 g / km, CO – up to 0.8 g / km and NO – up to 0.06 g / km.

When the exhaust system is without a catalyst, oxygen sensors will detect more harmful emissions. Accordingly, you need to make sure that you do not feel the absence of this important detail.

There are various ways to repair of converter unlimited st. We tried to briefly outline the main pros and cons of various types of repair of converter unlimited .

Diagnostics of converter unlimited

In many cases, correct diagnosis of a catalyst allows you to understand the real cause of breakdown and not just change the converter unlimited. Usually  converter unlimited error can catch fire literally from scratch. For example, a catalyst error can catch fire from damage or other part of exhaust system. It could just “shut down” the wiring or computer.

Types of diagnostics that are offered:

computer diagnostics (reading all errors and their analysis), endoscopy of converter unlimited (examination of the state of a catalyst), physical examination of exhaust system, measurement of purity of exhaust gases for compliance with EURO4, EURO5, EURO6 standards.

1. Replacing converter unlimited with a new one. If you need a replacement of a catalyst, then it is a due time to sell the old one. You can choose a converter unlimited that suits you with its cost and its properties.
2. This repair path is undeniably most correct, but the most unreliable in the long term, because after two thousand kilometers  converter unlimited will again need to be replaced. The main advantage is that exhaust gases will be clean.

2. Replacing the converter unlimited with a flame arrester. This procedure has two popular names, one of them is “replacing catalyst with a flame arrester,” and the other is “removing theconverter unlimited ”.
3. In this case, you get rid of catalyst and everything that is connected with it. But having removed it you will gain following consequences: exhaust sound will become loud, exhaust system will easily burn out.

3. Rinsing, cleaning catalytic converter. In case of catalyst error has arisen due to the fact that the catalyst is clogged with combustion products, and this is the only reason why catalyst does not work. It is necessary to clean it and thereby remove any deposits.
4. But if functional catalyst deposition layer has lost its properties, then this does not make sense, and replacement of catalyst by one of methods is required. Only diagnostics and inspection of the car can tell which is the best option for a catalytic converter.

Service stations

will carry out exhaust system diagnostics in order to 100% determine whether it is worth cutting out the converter unlimited or, possibly to clean it. It is difficult to determine the cause of failure yourself.

One way is to dismantle part of exhaust system, including the catalytic converter and remove contents of catalyst. Usually several holes with a diameter of 20 mm are made using a punch.

This method has disadvantages: holes quickly become clogged again. But there are also positive aspects, since you do not have to cut metal and do welding.

Why one should remove and replace the converter unlimited?

If you need to cut out the catalyst, the price will depend on what you want to get on as a result. For those who are confused with a choice, experts can advise the best repair option.

Take a look at general figures and prices of a converter unlimited repair and replacement cost for some common vehicle models. Find a way to save money, selling your old catalyst to a specialized recycling organization and gain a good money bonus for future investments.

Old converter unlimited

can be sold to a number of companies associate with refineries with contracts for the recycling of their enriche raw materials.

The scope of activity of such companies includes the purchase of spent converter unlimited  from private and legal entities.

concluding a contract of sale, the company analyzes the converter unlimited which valuable element it contains, and in what quantity.

Based on the analysis, the transaction value is determine.

On average, for foreign cars prices are per 1 kg of catalyst vary from 50 to 150 USD, depending on the car brand.

converter unlimited from Hummer

, Land Rover, Infiniti, Jeep GrandCherokee, Lexus, Mercedes-Benz reach the highest costs.

Prescious metals in a converter unlimited

In the modern cars there are a lot of interesting things.

It turns out that there are even noble metals in it and the car owner hims

Not everyone knows that the so-called exhaust system converter unlimited or rather, an exhaust gas converter unlimited contains precious metals of the platinum group.

First of all, it is actually platinum, as well as noble metals palladium and rhodium.

Therefore, after the automotive  converter unlimited fails and this usually happens after 150-200 thousand kilometers,

you can take it to special processing companies, which are able to extract precious metal for recycling.

The main nuance of this procedure is that platinum metals are in a form of a very thin layer spraye onto porous ceramic cells.

In fact, the device is conceive as such, so that the contact surface of exhaust gases with metal catalyst is as wide as possible.

Therefore

, collecting spraye platinum from 20 thousand square meters of the inner surface of the honeycomb is not so simple.

To do this, it is necessary to “rinse” converter unlimited ceramics with acids, heat, galvanize, crush… But this, in fact, is a problem not of a motorist, but of other people.

How to determine the profit which a converter unlimited can bring to a driver owing to this?

To determine the number of platinoids, an RF spectrometer is used, it is also an X-ray fluorescence analyzer.

But first of all

, you need to see the catalyst case, pull out the ceramic filler and grind it. Then, correlating the data of spectrometer and mass of ground filling, the receiver determines the price.

The average price of a  converter unlimited that has worke out is from 20 to 150 USD, and you can get them just passing an unnecessary converter unlimited at the pick-up point.

It is interesting that evaluators take into account the current quotations on world exchanges when evaluating.

And this figure relative to platinum can experience significant fluctuations, for example: depending on the situation, one ounce in different periods can cost several hundred dollars and one and a half thousand dollars.

The content of precious metals in a catalyst is determined using a spectrometer. Incidentally, it is able to distinguish platinum substitute.

To understand:

the content of pure platinum or other platinoids is tenths and hundredths of a percent of the total mass of converter unlimited filling.

handing over the old for recycling will be the most rational step.

And even if you  want to buy a new catalyst and intend to replace it with a substitute, you should still think about recycling.

The price is worth the time spent on the delivery of precious recycle materials.

The platinum content in Japanese and Chinese cars is 15% less than in Europe, in catalysts of Russian cars 40% less than rhodium in Europe.

In American catalysts, precious metals are half as much as in European ones.

To solve the problems of processing converter unlimited, hydrometallurgical and pyrometallurgical methods are used.

The source for processing contains a large amount of ceramic carrier and an insignificant concentration of precious metals.

When processing waste electronics, the source is scrap parts that contain, as a rule, plastic particles in their composition.

Classic symptoms of a malfunction are a decrease in dynamics of a car and a noticeable cut in engine power. As a result, the level of maximum speed decreases; the car accelerates sluggishly during overtaking or when starting at a traffic light. Additional signs which shows that  converter unlimited is clogged or not:

1. Motor starts hard on both hot and cold temperature, a strange sound appears.

2. Power unit may fail completely if the assembly is too clogged.

3. Exhaust fumes start to smell unusually, this smell resembles a rotten egg (in fact, it is hydrogen sulfide).

One way to identify a clogged catalyst is by checking the CheckEngine indicator light on the car dashboard. Often in such a situation, it lights up. Same symptoms are observed on a diesel engine.

In case of damage to wires that transmit the signal from sensors, or unexpected destruction of active substance, warning lamp lights up. Sensors are mounted after the outlet and before the inlet pipe, they serve to control the oxygen concentration. When converter unlimited clogging occurs gradually, the bulb does not let you know that a system problem has occurred.

The reason for this may be poor ventilation of cylinders. When it weakens, the power unit cannot capture enough air the increased back pressure of catalyst interferes. The exhaust partially remains inside cylinders and does not allow the air-fuel mixture to properly fill the combustion chamber. For this reason, dynamics worsens, power decreases. The main thing to know is if the catalyst is clogged, how the machine behaves and why it is dangerous.

How to identify a clogged converter unlimited?

For the following reasons, converter unlimited is usually clogged:

1. There are certain defects in engine or exhaust system. For example, the increased oil content in exhaust and its increased consumption.

2. Low-quality fuel that does not completely burn out in cylinders and burns out already in exhaust manifold. converter unlimited may melt or simply overheat.

3. Too small throughput cells of a converter unlimited . They quickly clog, and even small droplets stick because of heat.

4. Poor quality pavement affects catalyst clogging. From constant mechanical shocks about bumps, speed bumps, mounds suffer from its internal components. And if at least one cell is damaged, then its particles can clog remaining cells.

Implications for an engine

Do not neglect tips to check the converter unlimited for clogging, since consequences of driving with such a node can be most severe for a car.

A defective element provokes following problems:

• Increased operating costs of gasoline due to increased resistance of the exhaust tract.

• Exhaust fumes contain a lot more harmful substances.

• Engine power drops significantly, and, consequently, comfort of a trip in a car.

• The main thing that threatens a long ride with a clogged converter unlimited is a complete breakdown of gasoline engine. At one point, it will stall right in the process of movement, or it won’t start at all.

It is especially dangerous for motor if the internal filling of a catalyst is destroye.

In this case, solid particles are forme that penetrate the cylinder and become clogge between the piston and the inner surface. Because of them, damage is forme on the mirror, and they can be remove only by grinding.

How to check the converter unlimited for clogging without removing it?

Three most common methods to find out that a converter unlimited is clogge:

1. Complete dismantling of working unit and its external inspection for signs of clogging. Removing the  converter unlimited is sometimes problematic because it tightly sticks. In this case, the specialist uses a grinder. Also, some cars have such complicated designs of exhaust systems that it is generally impossible to remove catalyst or it takes several days.

2. Measurement of pressure in exhaust system. To measure it, it is necessary to install the pressure gauge in place of the 1st oxygen sensor, and then take readings at different engine operating modes. The pressure is considere correct at level of 0.3 kgf / cm², at 2.5 thousand rpm.

3. It is often difficult to remove sensors.

4. Back pressure measurement with a special tester.

5. A pressure sensor is mounte in a place of the spark plug in the engine cylinder, after which an oscillogram is analyze at increase speeds.

The replacement or repair of the converter unlimited is definitely require in a situation where the pressure in exhaust system is more than 200 kPa (almost 2 kgf / cm²).

converter unlimited

If converter unlimited is defective, then when it is remove, the car engine regains its original,

factory parameters, it begins to “breathe” more easily, resulting in reduce fuel consumption and increase power.

In cases where the converter unlimited is removed in order to modernize the exhaust system, this procedure is usually supplemente

by installation of a new exhaust pipe type silencer, which creates significantly less obstacles to exhaust gases than the catalyst.

In combination with reflashing of a power unit

(which is also performe), this leads to an increase in power of a power unit

. It should be note that this method of tuning is often calle “amateur”, because when tuning the exhaust system performe

by professionals (used, for example, to “refine” sports cars),

Professional tuning is done only by highly qualifie specialists and costs considerable amounts.

Modern motorists have an excellent opportunity to get rid of a faulty converter unlimited when and where they want to do it. Usually there are plenty of car service stations which are ready to give some information on purchasing old catalysts. Specialized companies always buy used converter unlimited in any quantity and offer good deals, both to individuals and large suppliers.

Now you can sell converter unlimited, the price for the device will be high, and the operating conditions are usually transparent. The purchase of converter unlimited is equal for both from foreign and domestic manufacturers in any condition. You can calculate the cost of a scrap converter unlimited using a special calculator or simply by calling consultants. It is not only a profitable but also a satisfying process, due to your will to recycle the old item.

In which cases should the converter unlimited be sold

Is it really necessary to consider mileage and driving conditions? Should everyone follow a producer’s manual? Which signs can help to understand the vehicle problem? These questions and many others are usually concentrated in heads of modern drivers, thinking of their car maintenance cost.

A converter unlimited malfunction is indicated by the power unit decreasing in its work. It is easy to perceive because of some distinctive features. This occurs when the honeycomb structure melts or becomes clogged with soot and exhaust gases are difficult to escape. An additional booming or rattling sound indicates the destruction of the car’s ceramic of a converter unlimited. Excessive smoke with an unpleasant smell comes out of the exhaust pipe in case of a failure.

Processing is a basic need for individuals who need to discard or improve the working of their exhaust systems. The best spot for this is to find scrap vendors. They are the best companies to sell or reuse your converter unlimited. It is always better to collect more information on prices and possibilities to recycle a converter unlimited.

How to independently determine the price of a converter unlimited

Talking about the causes which affect the price of a converter unlimited, it is better to mention general ones. Sales market is one of the biggest influencers. Better converter unlimited are provided for the European car market, and if you need to sell a car catalyst, originally intended for third world countries, then they will not give a high price for it.

The quality of the converter unlimited  will also depend on the class of vehicle it is installed on. High mileage and long-term operation negatively affect converter unlimited, and therefore are not very optimistic about its value. As you know, the converter unlimited  has the property of “emptying”, and therefore a sporty driving style will make it cheaper. If certain additives are present in gasoline or other fuels, then over time the precious metals will be washed out.

Usually the composition of a car  converter unlimited initially contained Pt, Pd and Rh. With time and modernization, the contents can change, but the idea and process of purification remains the same. One ton of ceramic converter unlimited contains about one thousand and five hundred ppm of Pt, almost one thousand ppm of Pd, and about three hundred ppm of Rh.

Diesel converter unlimited or premium cars

Diesel converter unlimited or premium cars contain Pt and Rh. Although their metal contents are about 2.5-3.5 thousand ppm. In general, the acceptance of converter unlimited with similar content is about seventy percent. The cost of such parts of the exhaust system on average varies between sixty to seventy five USD per 1 kg. This type of a catalyst can be attributed to an endangered species, and according to some sources, the average price for it is up to eighty USD per 1 kg. Considering these simple figures one can understand the price of the scrap item. Calculate it by yourself and discover benefits from selling. Profit from a great deal with one of your local recycling stations.

Myths about scrap converter unlimited prices

Let us look at several myths about scrap  converter unlimited prices and how to decide what is right and what is wrong. The first one is that diesel is always more expensive than gasoline catalytic converters. When evaluating a converter unlimited, do not rely on the type of engine.

In modern diesel cars, a particulate filter is used and catalysts are installed on all power units, both gasoline or diesel. It is better to pay attention to the year of manufacture and the class of the car. Second myth is that old  converter unlimited are more expensive than new ones. It is new items that contain more precious metals.

And the last, but not the least is that European converter unlimited are more expensive than others. This is also a wrong judgment, because the highest price for buying catalysts will be not only for a high-quality European converter unlimited, but also for their Japanese counterparts.

Protect your car and drive safely

It is common that all converter unlimited have sequential numbers, and this is something that can be utilized to decide the purchasing cost. Experienced organizations will request the sequential number of your item before providing the cost estimate tag.

Protect your car and drive safely to earn on scrap converter unlimited! The sum you get will be of great help when it comes to repairing the catalyst. More and more companies offer recycling of old converter unlimited and looking around attentively, you can find your best partner.

Since there are no moving parts on a converter unlimited, you would expect that they would be fairly durable and long-lasting. They are but, in spite of all the advancements in converter unlimited  technology, they still fail. Many times, catalytic converter failure is a symptom of an issue somewhere else in the vehicle.

It is important that you fix the problem that caused damage to converter unlimited, because if you don’t, that same problem will likely destroy the replacement converter as well.

• Power reduction and acceleration.

• If there is a problem with the exhaust system, this will begin to affect engine performance. You will not be able to accelerate as fast as with a healthy system. Simply put, the motor loses power, often it will also require replacing converter unlimited.
• Rattling sound coming from beneath. A rattling sound coming from your car is never a good sign. When a catalytic converter becomes damaged, it can cause honeycomb break or collapse. When you turn on your vehicle, these pieces will vibrate and make a rattling sound.
• Long way to start.  converter unlimited problems cause gas within your engine to heat up to the point that it actually ignites. This ignition is what causes the misfiring sensation. That can destroy engine components. Anytime your vehicle misfires, you should have it checked out for converter unlimited damage.
• Reduced fuel efficiency.
• When your power and acceleration decrease, often fuel efficiency also decreases. With a faulty system, fuel consumption may be less profitable than before.
• Smell of burning from the engine compartment. If a malfunction occurs, a gas leak may be observe. Due to high temperatures, surrounding parts may melt. When drivers smell fused plastic or burning they should immediately stop the car, remove all passengers from the passenger compartment, and then carefully check what is happening under the hood.
• Gas smell. If you smell gas inside, this may be a sign of problems with converter unlimited . This usually happens when one of the exhaust pipes or pipes is damage and begins to flow. Gasoline vapors exit through the crack. Sometimes this leak may be located inside.

These are just a few common signs to understand if the converter unlimited is damaged. If you notice at least one of them or it seems that something is wrong with the catalyst, try to find out the reason with the help of several tests. The driver can diagnose the converter unlimited malfunction independently, if he has the proper knowledge and necessary equipment. There are 3 main ways to test the converter unlimited

1. VISUAL INSPECTION.

Presence of problems in the converter unlimited can be determined “by eye”. If it is deformed, there is a good chance that honeycombs of the converter unlimited are damaged. At the same time, it will not be possible to inspect the device from the outside for clogging with dirt and combustion products. That is why, it will be necessary to remove the catalyst. After removing the converter unlimited, it is necessary to inspect it for the presence of gaps. Clogged converter unlimited can be cleaned or replaced with a new one.

2. converter unlimited PRESSURE CHECK.

The most common method for checking a converter unlimited that does not require dismantling. Essence of a back pressure test is that the exhaust pressure is measure, which is then compare with ideal indicators. To diagnose it, you will need a manometer and adapter to connect it. It is better to lift the car or drive it into a pit. Next, you need to remove the first oxygen sensor, and connect a pressure gauge in its place.

3. DIAGNOSTICS BY MOTOR TESTER

The motor tester is a set of equipment that allows you to determine the state of many parameters. With this method of verification, a diagnostic device is installed instead of the spark plug, after which the engine starts and waveforms are taken. On their basis, experts make conclusions about the state of a converter unlimited. By eliminating problems with the converter unlimited in time, you can avoid costly engine repairs and significantly reduce fuel consumption.

In case it is heavily damaged and has to be replaced, contact specialized companies to get a payback for your old converter unlimited.

Common converter unlimited evaluation is as follows:

• Fixing the cost of the converter unlimited is determined by the marking on the housing.
• Establishing value of precious materials.
• Acceptance of all kinds and types of converter unlimiteds. The cost also depends on the condition and integrity.

Damaged converter unlimited with ceramic part of the monolith should not be washed with any chemical solutions. It has to be clean without natural moisture, asbestos. Ceramics in metal housings of aconverter unlimited  has to be also clean and in full size.

The high cost of converter unlimited is due to the use of platinum, rhodium or palladium salts. Specialized companies purchase broken, defective, renewed and destroyed  converter unlimited of all types, and also accept them for useful components with an aim to subsequent manufacture of new converter unlimited.

“They’re going after the solid raw materials,” he said.

“They cook it down to the point where no one’s going to put the effort in to find where it came from.”

“I’m pretty sure most of it goes out of the country so no one asks any questions,” he said.

Sawyers thinks the materials aren’t being sold to auto shops, necessarily, but pawn shops,

who’ll buy the solid metals and ask few questions.

He also suggeste that there are organize groups running converter unlimited schemes,

a theory he came to by identifying the methods by which the parts were remove.

He said one presumed group uses a specific tool that “makes a very clean, straight cut. It’s very identifiable.”

Another presumed group appears to use a different sort of tool that “can go through a chunk of exhaust pipe in 10 seconds.”

“If they spend five minutes doing this,” he said, “they’re lazy. It’s so stupid easy to do. I think that’s part of why it became such an issue, the catalytic converters are just hanging there. It’s literally two bolts and one cut.”

the wholesale parts manager at a San Francisco Toyota dealership, estimated that there was a period when the dealer was selling

“a couple hundred catalytic converters a month.”

He said the most common vehicles that thieves hit are 2004 to 2009 Toyota Priuses, which he thinks are easier to steal from. The Prius catalytic converters are also known to contain a higher volume of precious metals.

“It’s sad,” he said. “I’ve seen customers pick their car up after getting the part replaced, and literally within the same day, it’s stolen again.”

When asked about the rash of Prius catalytic converter thefts

, and whether they’re planning to design vehicles that are more difficult to steal from, Toyota headquarters offered the following statement: “Catalytic converter theft is an industry-wide challenge

We want to remind drivers to follow the basics to protect their vehicles against theft – such as parking as close to entrances as possible in well-lit areas.

While not the solution to the problem as a whole, taking preventative measures like smart parking and adding the Vehicle Identification Number (VIN) to the catalytic converter can help protect drivers from theft.”

Everyone interviewed for this story agreed the best way to protect your vehicle from theft is to park in a well-lit garage — an expensive commodity often hard to come by in San Francisco and neighboring cities.

The police spokespeople also stressed the importance of providing investigators with photos and video footage, if possible.

“Video cameras, pictures, anything that you can do that you think might help, submit what you have, file a report,” Lobsinger said. “A report does two things: It gives us more to look into. And it shows us where there’s been a rash of thefts.

The more we’re aware of these incidents, the better we can deploy our resources and tailor our investigations.”

Sawyers had other suggestions. He said the cages and plates sometimes work to deter theft, but only if “somebody with less of a hassle is parked next to you and they go after that one instead.

“It only works if there is lower-hanging fruit nearby,” he said.

I got $200 for it.

I bought a used Prius, perhaps despite my best judgment, upgrade my car insurance to cover catalytic converter thefts and, in the meantime, am hoping for the best.

There is a converter unlimited in all modern vehicle exhaust systems. A converter unlimited will last for ten years or more on a routine basis if well maintained.

The truth, however, is that they can become polluted, clogged, overheated, or physically damaged, resulting in slow engine output.

Car engines need a lot of oxygen, which means that less air will enter the system if the exhaust flow is limite and efficiency suffers.

If the engine responds sluggishly or stops after running for a while, it could trigger a clogged converter unlimited.

Because of excessive quantities of unburned gas caused by a misfiring spark plug or a leaky exhaust valve, converter unlimited may overheat.

A malfunctioning oxygen sensor can also cause overheating. It may also be damage by road debris or driving over a curb, like other parts of the exhaust system.

How a converter unlimited Works

The toxic gases created by the car’s engine pass through a converter unlimited after a vehicle is starte.

A honeycomb pattern composed of precious metals such as platinum, palladium, and rhodium consists of the converter unlimited’s internal structure.

The converter unlimited is usually built to operate at a high temperature of around 800 ° F. A chemical reaction occurs,

resulting in safer components, such as oxygen, water, and carbon dioxide, coming from your mufflers.

Causes of a Bad converter unlimited

Most converter unlimited can last a vehicle’s lifetime, as described earlier. But a converter unlimited  can go wrong in some situations and needs to be replace.

Almost all converter unlimited issues are due to a problem with the engine. It is most frequently cause by excess fuel entering the exhaust system owing to an inaccurate air/fuel combination,

bad spark plugs, wrong engine timing, failed oxygen sensor, or other problems where fuel exits the engine’s combustion chamber unburned.

The converter unlimited reaches a temperature that is too high when this occurs and starts melting the inside or tearing the honeycomb material apart.

This will then make the  converter unlimited from not working correctly.

Failed gaskets, lousy valve seals, or worn piston rings may also trigger oil or antifreeze to enter the exhaust system and coat thick carbon soot on the ceramic converter unlimited inside theconverter unlimited .

If this is allowe to go on long enough, the converter unlimited would be clogge by these carbon deposits, so it can’t do its job.

In this case, the exhaust flow is blocke entirely, and the backpressure builds back to the engine, which can cause overheating and other problems.

Lastly, there can be physical harm to the converter unlimited. Rocks, road debris,

or potholes can get or break the outer shell of a converter unlimited or the hangers that protect it, but it’s not common.

Repairing a Bad converter unlimited

If you think you have a bad or clogge converter unlimited,

you can remove the clog by adding a catalytic converter cleaner to your gas. More than one use might be appropriate.

Removing the cat and soaking it in a citric acid solution for 6-8 hours is an alternative and very sturdy way of cleaning a converter unlimited.

Using sodium hydroxide is another choice. If the catalytic converter is broken, including parts of the honeycomb breaking off inside,

attempting some repair is not fee-sable, even though you can see some people claiming otherwise. Repairing it is your only choice in these situations.

How to Prevent the converter unlimited From Clogging

The chance of your  converter unlimited failing before it’s due will be reduced by having your exhaust,

emissions, and combustion systems in the right conditions. The critical problems of acid rain and smog are these extremely hazardous substances,

especially in low-lying valleys and critical metropolitan areas.

If you travel short distances with your car regularly, the hydrocarbons will not be burnt away because the converter unlimited does not get the chance to get hot enough.

Try driving your car on the highway now and then for about 10 to 15 minutes to minimize the chances of getting a clogged converter unlimited.

To effectively burn off these hydrocarbon deposits, the requisite heat will be produced inside the converter unlimited, so it needs to run as efficiently as possible.

Final Words

A vital component of your car that needs to be maintaine is theconverter unlimited.

Once the converter unlimited of your car goes terrible, other parts of your vehicle will be affecte.

Some would say, however, that you can still drive while the catalytic converter is defective, but it is not advisable to do so.

If well maintaine, the converter unlimited  lasts for a long time, but if you notice that your catalytic converter is wrong, fix it or get a new one to prevent other parts of your car from being damage.

1. Two way converter unlimited : this is the much older type of converter unlimited. It carries out a dual function of oxidizing carbon monoxide to carbon dioxide and oxidation of hydrocarbon to carbon dioxide and water. This chemical reactions occur at the same time.
2. Because of the inability of a two way converter unlimited to filter out oxides of nitrogen, they are no longer use in most countries today.
3. Three way oxidation reduction: this is the more advance type of converter unlimited. Here three different reactions happen simultaneously. The reactions are the reduction of nitrogen oxide to nitrigen and oxygen, the oxidation of carbon monoxide to carbon dioxide and conversion of hydrocarbons to carbon dioxide and water.
4. Diesel oxidation converter unlimited: this type is used on a diesel engine as the name implies. It makes use of the oxygen present in the exhaust to convert carbon monoxide to carbon dioxide and unburnt hydrocarbon to water and carbon dioxide.

Where do the harmful gases come from

The engine  used in a car is known as an internal  combustion engine. This engine run on gasoline which are fractions of crude oil distillation.

When the gasoline is burne with oxygen from the air in the engine, it produces water and carbon dioxide in the gaseous form. This is accompanied by other substances including toxic materials.

Harmful gases are also produce when we use leade fuel in our cars.

A bad  engine is also a culprit as it doesn’t burn the fuel efficiently, this causes unburnt substances to pass out of the exhaust. This is likely to happen as the engine experience wear and tear after along time of usage.

Why should I be concerned

Environmental impact of harmful substances released by the exhaust of vehicles are devastating. This toxic substances include hydrocarbons, carbon monoxide and nitrogen oxide. Hydrocarbons accumulation will produces smog as witnessed in large cities. Carbon monoxide is a poisonous gas that harms both humans and other animals while the nitrogen oxide causes acid rain and smog.

This harmful substanc

es are also thought to cause global warming in the long run.

This is why the converter unlimited is employe to reduce emission of this substances.

How effective are converter unlimited

converter unlimited have proven to be highly effective in controlling toxic emission. Recent studies have shown that a car that has a converter unlimited installed will produces 87% less hydrocarbon, 85% less carbon monoxide and 62% less nitrous oxide in its entire life cycle.

The converter unlimited typically last for ten years but like other car components, this may not always be the case. There are a lot of factors that are responsible for the damage of aconverter unlimited . Generally, after 50, 000 miles of driving it will not be as effective as a new one and it is right to change it now.

It is a durable component of the car that hardly gets damage but if it eventually gets bad, it will lead to a sluggish engine performance or total shutdown.

In an ideal situation, the converter unlimited is replace only two times in a particular car.

Maintenance tips for your converter unlimited

• Avoid speeding through bumps and pot holes as they can potentially damage your converter unlimited .
• Remember they are installe under the car.
• Install an alarm system in your car, this will ensure your converter unlimited is not stolen from your vehicle.
• Other contaminate of a converter unlimited is the enggine coolant when it leaks into the combustion system. Always check to make sure the cylinder head is intact to prevent this leakage.
• Don’t use leaded fuel as this will make the converter unlimited inactive, thereby preventing it from working properly.

Final say: the converter unlimited is a durable component of the car, it will last as long as you maintain it. Because of the special elements it contains, it is a major target of car theft. Make sure you park in a good place and have your alarm switched on.

Whenever you need to replace it, make sure you get a good one and also ensure it is properly installe.

Since there are no moving parts on a converter unlimited,

you would expect that they would be fairly durable and long lasting and they are but,

in spite of all of the advancements in converter unlimited technology, they still fail.

Weatherford

, Texas, we install replacement converter unlimited  almost every day. Many times,

catalytic converter failure is a symptom of an issue somewhere else in the vehicle.

It is imperative that you fix the problem that cause your OEM converter unlimite to fail because if you don’t,

that same problem will likely destroy the replacement converter unlimited as well.

The warranty that comes with a new replacement  will not cover the type of damage listed below.

If your factory installe converter unlimited needs to be replace, one of the problems below most likely contribute to its failure.

Engine Tune-Up Required
Engines in need of service and older engines that burn oil due to worn cylinder walls, stuck rings, and worn valve guides will produce by-products that can foul the converter.

When an engine is operating outside of the proper specifications, wear and damage may be cause to the catalytic converter as well as the engine itself.

Incorrect air/fuel mixture, incorrect timing, or misfiring spark plugs could lead to a converter unlimited failure or worse.

Bad Spark Plugs or Spark Plug Wires
Spark plugs that don’t fire or misfire forces unburned fuel into the exhaust system.

Because the converter unlimited gets very hot,

this unburne fuel can ignite inside the converter and could result in a partial or complete melt down of the ceramic converter unlimited.

Oil or Antifreeze Entering the Exhaust System.
When oil or antifreeze makes its way into your exhaust system creates a thick carbon

and soot which coats and eventually clogs the air passages in the converter unlimited ceramic honeycomb converter unlimited.

This causes two separate problems.

First, these carbon deposits stop the converter unlimited from doing its job of removing harmful emission in the exhaust flow. Second,

When the pores become clogged in the ceramic converter unlimited, exhaust flow is restricted which increases backpressure.

This results in heat and exhaust backing up inside the engine. The excess back pressure created can actually cause internal engine damage. Your engine can actually pull burnt exhaust gasses back into the combustion chambers

and reduce the efficiency of the next burn cycle and creating a loss of power and overheating of engine components.

Worn out piston rings, failing gaskets,

faulty valve seals or even warpe engine components are all possible causes of this problem.

Unburned Fuel Entering the Exhaust System.
Ideally, the fuel that powers your vehicle is burnt up in the combustion chamber.

Any fuel that gets through the combustion chamber unburne enters the exhaust system and can ignite once it reaches the converter unlimited.

This can over-heat the converter unlimited far beyond its normal operating limit. and cause a Melt Down.

Possible causes are an improper fuel mixture, incorrect timing, bad spark plugs, a malfunctioning oxygen sensor, sticking float, defective fuel injector or a faulty check valve.

converter unlimited engine is part of the exhaust system and is located in the immediate vicinity of a vehicle’s exhaust manifold.

converter unlimited enters into that incandescent exhaust manifold, and after that, significantly slowed down, cooled and cleaned of harmful substances, it appears in a resonator and in a muffler.

The principle of operation of a catalyst is based on chemical reactions that neutralize harmful emissions of nitrogen oxide, carbon, and all kinds of hydrocarbon groups.

main element of a converter unlimited

The main element of a converter unlimited is made in a form of a massive ceramic or metal block with small honeycombs, on walls of which precious metals are applied:

an alloy of iridium and platinum, as well as rhodium and palladium. When touching chemically active surfaces, harmful compounds are burned and removed from the exhaust pipe in the form of harmless N2 and CO2

.Platinum and palladium act as oxidants in a catalyst and greatly accelerate the combustion of hydrocarbons.

active element is placed in a metal casing and provided with a layer of thermal insulation.

converter unlimited not only traps and neutralizes harmful compounds but also directly affects the operation of an engine.

Signals from sensors located at the input and output of a converter unlimited are constantly read by the “brains” of a car and help to optimize working mixture in the best way.

It is better to know in advance all possible reasons for a malfunction to avoid engine and vehicle damage.

converter unlimited malfunction symptoms

The service life of an expensive converter unlimited is usually about the same as the service life of the entire car, but it often breaks down much faster than it should be and can pull the engine with it.

It is important to remember that a converter unlimited does not fail for no reason. Its breakdown is a sign of improper operation of the ignition system, incomplete combustion of a mixture in cylinders, severe engine wear, or prolonged use of low-quality fuel.

You can understand that your catalyst is being scrapped by several characteristic symptoms:

– the decrease in motor performance;

The most common symptom of a catalyst failure is a severe decrease in engine power.

The car starts to lose momentum and accelerates poorly. Engine runs unstable, overheats, and stops.

This happens when the throughput of a converter unlimited is greatly reduce:

the honeycomb is destroye, melted and sintere, clogging the hole and interfering with the free passage of exhaust gases.

At the initial stage of such converter unlimited malfunction, the car will accelerate to a relatively low speed,

the engine starts hard, and then “suffocate” and stall. Fuel efficiency also deteriorates markedly. Also, during a cold start, a strong unpleasant odor appears.

– rumble under the bottom;

A loud rumble under the underside of a car indicates that the active element of a catalyst has begun to deteriorate and fall apart.

Ceramic converter unlimited fragments affected by exhaust gas flow randomly beat against walls of a casing and create an unpleasant rumble. As a rule, this is most clearly manifested at increased engine speeds and during start-up.

– low pressure of exhaust gases from a muffler

If you bring your hand to an exhaust pipe, you can feel a pulsation. Exhaust valves of cylinders work alternately. If the exhaust flow is even and constant at idle, this is a sure sign of a clogged catalyst.

If you increase the speed and then turn off the engine, exhaust gases will continue to build up pressure for a short time, gases accumulated in the clogged converter unlimited pipe come out.

– activation of Check Engine icon on a dashboard

The most common symptom of a catalyst failure is a system error that activates the engine trouble icon on a dashboard.

If this symptom appears, you need to immediately read the error code with a diagnostic scanner and fix the problem. If car “brains” detects incorrect readings on oxygen sensors,

they immediately notify the driver of this, and at the same time put the engine control system into emergency mode. This is often accompanied by a deterioration in dynamics and increased fuel consumption.

Computer diagnostics in this case often detects errors P0420 (low catalyst throughput) or P0430.

Causes and consequences of converter unlimited failure for the engine

Failure of a converter unlimited does not occur

suddenly and without reason. With the correct operation of all other systems, it faithfully serves for many years until the moment

the vehicle is scrappe (and often survives it). If the catalyst breaks down on your car, melts, or crumbles, you will almost certainly have to diagnose and repair the ignition or power system.

As a rule, the converter unlimited is damage precisely due to the incorrect operation of these two systems.

With a faulty ignition system, fuel in one or more cylinders does not burn out completely but enters the exhaust system.

The second catalyst is force to burn off increase volumes of hydrocarbons,  which leads to their sintering. Spark plugs, coils, or high-voltage wires can cause major trouble.

A malfunction of injectors, which begin to pour fuel, leads to similar breakdowns.

Worn or stuck oil scraper rings of cylinder-piston group or failure of oil scraper seals lead to the same result, only engine oil burns out in a converter unlimited.

Another common cause of converter unlimited failure is severe mechanical damage leading to the deformation of the housing.

It is important to remember that thin-walled combs can easily crumble even with minor physical exertion. Leaving off-road, it will be useful to attend to the installation of additional protection for underbody as well as your car converter unlimited.

Failure to repair the converter unlimited is dangerous because small particles of ceramics can get through the exhaust tract straight into the engine cylinders.

Once there

, they instantly scratch the cylinder walls and completely disable the engine. Suffering from ceramic debris and turbine (if any).

Additional heating of the exhaust tract leads to deformations of the cylinder head and greatly reduces the resource of a power unit.

avoid critical breakdown, do not bring your car to a deplorable state and fix the catalyst malfunction in time. Fortunately, it is quite possible to do this even on your own.

Platinum, rhodium, palladium and even gold can act as a perfect  converter unlimited in the converter unlimited . Without them, the process would have been impossible.The entire filling of the converter unlimited looks like a layer of precious metals deposited on ceramic honeycomb. And the converter unlimited is not only a unit, but also a housing, and lambda sensors, and a heat insulator casing.It is the ceramic block that is the converter unlimited of the reaction, and not the entire item assembly that is “dusting” into the cylinders, so they usually talk about removing the converter unlimited , sometimes replacing it with other parts.

The first converter unlimited was install in 1975. But there were no big problems from them then, and until recently no one could have thought that the converter unlimited could cause scuffing and oil scrapes. The converter unlimited was located far from the cylinder block, in the exhaust system somewhere under the bottom of the car. Yes, the converter unlimited can die there too: clog up and fall apart. And this is very important for all car owners, not only unique vehicle fans.

The suffering is insignificant: the car pulls worse, but the motor remains intact. The error of the lambda sensors that do not understand what is happening with the amount of oxygen can also be annoying. The solution to the problem is elementary, a catalytic converter is change.

The situation become much worse when a  converter unlimited was place close to the unit. In case of destruction of the base, ceramic dust begin to enter the cylinders. There are still people who are convince that dust from the exhaust can not get into the intake.

At the time of valve overlap, when the piston approaches the top dead center,

when the intake valve is already open, and the exhaust valve is not close yet.

When the converter unlimited needs to be replaced

Engineers under the guarantee are partly to blame for the disbelief in the possibility of ceramic dust entering cylinders. They at one time convinced the victims of a converter unlimited that the destruction of this wonderful element could not happen.

Although, at the same time, the guarantee for the catalytic converter was only a thousand kilometers, and it was proposed to change the killed engine at your own expense. Ceramic dust can get into the cylinders.

Pay attention to this essential vehicle part, because there is nothing to do when the converter unlimited has to be changed. Cleaning theconverter unlimited  will help to prolong the life of your car and motor itself without much time and efforts.

A ceramic  converter unlimited will eventually fail on any vehicle. But the danger is primarily those that stand on the exhaust manifold at a distance of 15-20 cm from the cylinder head.

In addition, there are motors, where the converter unlimited was installe in the exhaust manifold, built directly into the cylinder head. Over time, there are more and more motors with collectors and the problem is more and more widespread.

converter unlimited failure: causes and consequences

The converter unlimited turns out to be really clogge to a brick state.

It is remove, ideally with a firmware correction. And the car starts to go. And after a while, its owner returns with a complaint about the oil consumption that has appeared. In most cases, the reason is very simple: the ceramic chips have already got into the engine and have done their dirty work.

The driver of the car must control the converter unlimited  by himself if it is possible, as the engine power depends on it. A dirty device will result in increased fuel consumption and reduced vehicle dynamics.

At first symptoms, you need to check the converter unlimited, which can be done even in the garage or in a car service.

Importance of this device for a car is essential not only for nature, but for laws of different countries. Strict rules request many vehicle control services.

Get everything is done in time and without drastic methods to avoid problems in future.

The engine has to respond better to the gas pedal. And the oil consumption of a scuffed engine is very dependent on the crankshaft speed. So there is a feeling that the “oil grub” appeared just after the removal of the converter unlimited. Although almost always it was in this case before: the piston was already ruine by dust.

converter unlimited removing

remove converter unlimited after it is already severely damage. It is worth checking cylinders with an endoscope. If there are bullies, active driving will only increase the already existing oil consumption. In addition, the present oil burner itself is capable of killing a normal catalytic converter. The oil mist with additives will clog it quickly enough due to an increase in pressure in the crankcase. In this case, the increase in oil consumption with the removal of the converter unlimited is very, very indirect. But there is a situation when the oil burner starts precisely because of the removal of the converter unlimited.

What is a converter unlimited? The converter unlimitedor ‘Cat-Con’ is a mechanical device. It reduces the harmful emissions created in the exhaust system of an engine. It is an important device as it works …

The converter unlimited or ‘Cat-Con’ is a mechanical device. It reduces the harmful emissions created in the exhaust system of an engine. It is an important device as it works with the harmful gases, which the engine creates during combustion of fuel. The main purpose of a  converter unlimited is to reduce exhaust emissions.

The Cat-Con reduces the harmful exhaust gases through chemical reactions. It reacts with the harmful pollutants in the exhaust gases and turns them into lesser harmful gases. The converter unlimited consists of a special catalyst. It is made of platinum and palladium which carries out the chemical reactions.

Construction of converter unlimited:

The converter unlimited housing consists of a honeycomb core from inside. It is coated with precious metals such as platinum and rhodium. These metals react with the engine’s exhaust gases. They reduce the toxic contents of the gases and turn them into carbon dioxide and water.

At first, it reacts with the carbon monoxide generated by the combustion of gasoline. It also reacts with the hydrocarbons formed by unburned fuel and other nitrogen oxide emissions. Thus, the cat-con converts these gases into less harmful by-products which are the carbon-di-oxide, water vapor, and nitrous emissions.

Types of converter unlimited:

There are three different Types of Cat-Cons. The first type is the oxidation converter unlimited. It reduces harmful pollutants such as the carbon monoxide (CO) and fuel hydrocarbons (HC) in the exhaust. Simultaneously, it often uses a secondary air injection. However, the oxidation converter unlimited only reduces a portion of the pollutants.

Dual-bed:

The second type is the dual-bed converter unlimited which offers more perfection. It works in two stages. There are two elements which are situated one behind the other. The first stage helps in reducing the amount of nitrogen oxide emissions. The second stage reacts with the hydrocarbons created by unburned fuel and carbon mono oxide. The manufacturers also provide the secondary air injection in the two-stage type cat-con.

Three-Way converter unlimited:

The last type is the Three Way converter unlimited. The Three-way converter unlimited helps in converting the harmful gases exhausted from the engine into harmless gases. The engine exhaust gases contain hazardous substances that cause damage to the environment. These include the oxides of nitrogen, hydrocarbons and carbon monoxide. The three-way  converter unlimited them into less harmful carbon-di-oxide, water, and nitrogen.

The three-way cat-con is the only device which reduces all the three pollutants in one go. It functions most economically. Thus, most manufacturers employ a three-way type in their vehicles which need to meet stringent emission standards.

Working of the Three-Way converter unlimited:

Furthermore, the three-way  uses two converter unlimited; namely reduction converter unlimited  and an oxidation catalyst. The oxidation  converter unlimited is made of palladium and platinum whereas reduction catalyst is of rhodium and platinum. However, both of them come with a ceramic honeycomb structure. Besides, it is placed in a muffler like a compact unit which fits onto the exhaust pipe. Mainly, the automotive industry uses the Three-way Cat-con. This is because the vehicles have to pass many regulations for emission control.

Thus, the converter unlimited plays an important role in reducing the amount of pollution created. It also reduces the harmful emissions and gases created in the engine and the exhaust systems of all the cars across the globe.

Here are five signs that something may be wrong with your converter unlimited :

• Your vehicle’s fuel efficiency suddenly drops.

• Your vehicle doesn’t accelerate when you step on the gas pedal.

• Your vehicle may refuse to start.

• Your vehicle fails an emissions test.

• The MIL or Check Engine light comes on.

The most common cause of failure in a converter unlimited in an older car is that it becomes so clogged that the exhaust gases can’t get through it to the muffler and out of the car.

(If air can’t get out the rear of the vehicle, it can’t come in the front end, so the engine dies because no air is coming in to form the fuel/air mixture.)

Every car sold in the United States since 1996 has had an OBD (On-Board Diagnostic) II system that tests the converter unlimited  (among many other things).

If the unit allows too much pollution to escape from the tailpipe, it illuminates the MIL and produces a trouble code that can be read by a technician with what’s called a “scan tool.”

The converter unlimited is sensitive to changes in the contents and temperature of the exhaust gases,

so another possible cause for failure is if the cylinder head gasket is damaged, allowing oil or coolant to get into the combustion chamber and be burned in the cylinders. Also,

if your ignition system isn’t operating properly, unburned fuel in the exhaust gases can cause the converter unlimited  to wear out or break down. This is another good reason for going for tune-ups at specified intervals!

The critical reason that people hear more and more about stolen converter unlimited is that these parts are moneymakers. They consist of platinum, rhodium, and palladium, all of which are precious metals. Because of this, a converter unlimited scrap value can yield well over $200 per piece, and some larger, rare converters can even fetch over $1000, based on the metal’s current scrap rate.

Since 1975,r—however, some converter unlimited interest crooks more than others. For instance, trucks and SUVs are effortless to get under, which makes them an excellent target. The higher up your vehicle sits, the easier it is to steal the converter unlimited. And, usually a larger engine will have a larger converter with more metal content inside.

From 2019-2020, Los Angeles County reported a  In the state of California, there was over an 85% increase in converter replacement service.

WHY WOULD SOMEONE STEAL A CAT converter unlimited?

Crooks love converter unlimiteds because they contain precious metals they can sell. Scrap yards offer around $200 for catalytic converters and more for bigger, heavier ones. How, then, does a thief remove a catalytic converter?

Criminals usually use a portable reciprocating saw to remove it, aiming to take the converter unlimited  off in less than a few minutes.

You might not be able to know that your converter unlimited was taken by looking at your vehicle, but once you start it, the sound of gargling open exhaust (think massive muffler leak) will immediately make it apparent. It will be loud – very loud, and louder when you accelerate and get on the road.

HOW MUCH IS A STOLEN converter unlimited WORTH?

Depending on the precious metal, thieves could sell a  converter unlimitedto a metal recycler for around $200. The recycler then removes the metal and resells it for over $5,000 per ounce. While there is no official record of catalytic converter thefts nationwide, crime is rising dramatically, increasing metal costs.

The unlucky auto owner will need to shell out $1,000 or more for a converter unlimited installation. If the thief breaks any additional exhaust components, such as cutting the oxygen sensors or destroying other exhaust work, expect the to go up.

HOW TO PREVENT CATALYTIC CONVERTER THEFT

Preventing converter unlimited theft can be difficult. One thing to keep in mind is that the process of sawing a  off is not quiet. Most thieves choose to do these in open parking lots at night, away from close detection. Fleet vehicles or trucks parked in open lots are often prime targets. Some thieves have become bolden though and have begun attacking neighborhoods. Use these tips to help prevent converter theft:

• Park close to entrances and in well-lit areas. If you need to park your car in an open lot, choose an area close to the main road where passers-by might see thieves trying to steal it. If you notice cameras in the lot, park near them
• Park your vehicle inside your garage, making sure to shut and lock the garage doors. If this cannot be done, avoid parking your truck or SUV especially farther away from the house – keep it close
• Install an aftermarket alarm that can sense vibration
• Install one of many available outdoor and night-vision security cameras and aim the camera at your parking area. While this may not prevent a thief from trying (no different than package thieves) it will give authorities video evidence that could help them find the perpetrator
• Use your landscaping and other lower-riding vehicles to your advantage. Remember, a thief has to be able to easy get under more-desireable vehicles like SUV’s and Trucks. These thieves do not have time to jack a car up. For instance, if you have Truck and a lower car, and one side of your driveway has a retaining way, or hedge bushes, park your truck as close to that side as possible, and the car as close to the truck at the side. While they may not prevent theft, generally thieves are going to choose easy targets. You have to out-strategize the thief!

On a car, the converter unlimited is attache to the exhaust pipe.

A metal casing contains a ceramic honeycomb.

The honeycomb is coate with a mix of platinum (Pt), palladium (Pd) and rhodium (Rh). These noble metals are good at resisting oxidation, corrosion and acid. That means they can stand up to bad weather and all the chemicals released by a car engine.

The noble metals in converter unlimited  act as .converter unlimited  are compounds that can trigger a chemical reaction without being affected themselves. The honeycomb structure inside a catalytic converter maximizes the surface area where reactions can take place.

converter unlimited use elements like Platinum (Pt), Palladium (Pd), and Rhodium (Rh) as catalysts (Let’s Talk Science using photographs by Periodictableru [CC BY], Hi-Res Images of Chemical Elements [CC BY and Alchemist-hp (talk) derivative work: Purpy Pupple [CC BY-SA 3.0] Wikimedia Commons (https://en.wikipedia.org/wiki/File:Platinum_converter unlimited.jpg“>Pt, https://en.wikipedia.org/wiki/File:Palladium_(46_Pd).jpg“>Pd, https://en.wikipedia.org/wiki/File:Rhodium_powder_pressed_melted.jpg“>Rh)).

What chemical reactions happen in a converter unlimited?

converter unlimited use reduction and oxidation ( reactions to reduce harmful emissions.

They use a reduction converter unlimited composed of platinum and rhodium. It helps reduce nitrogen oxides (NO_x) by removing nitrogen atoms from nitrogen oxide molecules (NO and NO₂). This lets the free oxygen form oxygen gas (O₂). Then, the nitrogen atoms attached to the converter unlimited react with each other. This reaction creates nitrogen gas (N₂).

Catalytic converters also use an oxidative converter unlimited composed of platinum or palladium. It helps reduce hydrocarbons (HC) and carbon monoxide (CO). To start with, carbon monoxide and oxygen combine to form carbon dioxide (CO2). Then, unburnt hydrocarbons and oxygen combine to form carbon dioxide and water.

Oxidation reactions for carbon monoxide and unburned hydrocarbons (© 2019 Let’s Talk Science).Modern converter unlimited also use oxygen sensors. They’re sometimes calle . They control how much extra oxygen gets pumpe into the exhaust stream.

Maintaining the correct amount of oxygen makes the reduction and oxidation reactions more efficient.

Researchers are looking at whether gold could be used in converter unlimiteds. That might sound expensive. But gold is actually cheaper than many other noble metals. And there’s more of it! In fact, we could run out of metals like platinum in the next couple of decades. In some places, people even steal converter unlimiteds just to get at the precious noble metals inside!

Some petrolheads see them as a nuisance, but cats are a vital component for your vehicle’s emissions control

What is a converter unlimited and what does it do?

The cat sits around a third of the way down the exhaust system and resembles a small metal chamber that receives exhaust gasses

and changes the chemical nature of them to reduce the volume of nasty emissions fresh from the exhaust manifold.

Within the cat

Within the cat housing is a ceramic-based honeycomb structure that is line with extremely precious metals, with each metal having a specific job in emission-reduction.

There are three main emissions produce by car engines: nitrogen gas (N2), carbon dioxide (CO2) and water vapour (H2O).

The catalytic converter however is mostly use to tackle the smaller,

more-harmful products that are produce due to the naturally-imperfect combustion process of the IC engine.

These are carbon monoxide, hydrocarbons and nitrogen oxides. Most cats these days are therefore calle three-way catalytic converters due to the three main types of emission that they manage to tackle.

A ‘’converter unlimited is a substance that accelerates a chemical reaction, and within a catalytic converter,

there are two types of catalyst. The first is a reduction catalyst which uses platinum and rhodium within the honeycomb to reduce NOx emissions.

NOx is produced by nitrogen oxide and nitrogen dioxide within the exhaust gasses.

The nitrogen gasses come into contact with the converter unlimitedmetals which rip the nitrogen atoms out of the molecules which in-turn releases cleaner oxygen to continue down the exhaust system.

The second converter unlimited type

The second converter unlimited type is an oxidisation catalyst which uses Platinum and Palladium to complete the job.

These catalysts oxidise or burn the carbon monoxide and hydrocarbons lingering within the incoming gas,

helping reduce the amount of smog produced by evaporated, unburnt fuel.

The final stage of emission control comes in the shape of an O2 sensor found just upstream from the cat.

with the on-board computer then able to adjust the air/fuel ratio to allow the engine

to run as close to the Stoichiometric point as possible.

This is the point at which – theoretically – all of the fuel entering the combustion chamber will use all of the oxygen provide to complete the combustion process.

Not only does this last stage help the engine’s overall efficiency,

it also allows the engine to provide the cat with enough oxygen to effectively complete the oxidisation process with the second catalyst.

The struggle of automotive engineers for environment has led to appearance of units that are not used for movement, but reduction of air pollution. converter unlimited is one of them.

A metal can with a ceramic honeycomb system “burns” exhaust gases inside and reduces the harmfulness of car exhaust. According to experts, you need to get rid of a  converter unlimited after 150-200 thousand kilometers.

It is for such a run that this node is designed. It’s better to do it as soon as fuel consumption starts to increase and the car starts to accelerate worse.

Removing converter unlimited and installing a flame arrester will cost much less than replacing converter unlimited itself.

But removing of catalyst will increase toxicity of emissions, so this option is not suitable for people concerne about environmental safety of our planet.

But converter unlimited is not eternal, sooner or later the converter unlimited is clogged, its cells are destroye, and it not only

ceases to fulfill its functions, but also prevents the engine from working. So which are the options for a car owner regarding replacement?

It is possible to replace a faulty converter unlimited with a new one, however such a replacement will cost a good sum of money.

Such converter unlimiteds are very expensive.

cost goes up to a quarter of market value of a used car.

there are models where several catalysts are installed, and each should be changed in case of breakdown.

Naturally, the majority of car owners prefer a more economic resolution, like installation of a flame arrester instead of a converter unlimited.

The advantages of this approach are the following:

1. Lower price. Replacing the converter unlimited with a flame arrester can cost 5-10 times cheaper than buying a new cat. There are no comments here.
2. A slight increase in engine power and lower fuel consumption. The flame arrester creates less resistance to exhaust gases than the converter unlimited, engine “breathes” better, which means it adds to the power. The increase, as well as fuel economy, is not very large, about 5-10%. Most drivers will not feel it. It is not worth it to specially remove the cataly converter unlimited sture, improving engine performance is a small bonus.
3. Reduced fuel quality requirements. converter unlimited react most sharply to bad quality gasoline and often it is because of that quality, catalyst fails. The flame arrester does not cope with such work.
4. This does not mean that after replacing a converter unlimited, refueling at cheap gas stations will be a good idea, but you don’t have to worry about an expensive and fragile part when using unfamiliar gas stations.
