converter unlimited began to be installed in order to reduce the harmful effects on environment of exhaust gases that are generated during the operation. However, not all drivers approve installation of converter unlimited, because the cost of this unit is quite high. In addition, due to low quality of gas, it is necessary to repair converter unlimited regularly. Specialized companies purchase used converter unlimited offering good money bonus.
What does the converter unlimited do in a car?
converter unlimited is one of components of exhaust system. Why is there aconverter unlimited in a car? converter unlimited helps to reduce the percentage of harmful substances in exhaust fumes. These include carbon monoxide, nitrogen oxides and hydrocarbons.
Today, vehicles are equipped with converter unlimited, which are made of noble metals.
When the engine is running, exhaust gas heat up the converter unlimited. Temperature of catalyst becomes quite high. As a result, noble metals burn out harmful substances, percentage of which decreases.
What does a converter unlimited consist of?
From the case with a base in form of ceramic or metal honeycombs. It is coated with a platinum-iridium alloy coating.
Due to honeycomb structure, contact area of exhaust gas and surface of catalytic converter layer increases. An oxidizing reaction of carbon monoxide and hydrocarbon proceeds in a converter unlimited. As a result, relatively harmless substances nitrogen and carbon dioxide come out of exhaust pipe.
Vehicle can run without a converter unlimited, but experts recommend mounting it when:
- Car age up to 5 years;
- Auto inspection is coming;
- Planning a trip abroad;
- Make exhaust less harmful to environment.
Types of converter unlimited .
All exhaust system converter unlimited are divide into the following types:
Bilateral
Carbon monoxide is oxidize to carbon dioxide, as well as fuel that has not burn or burne out, to water and carbon dioxide due to the combustion reaction.
Typically, these two-way converter unlimited are installe on cars with diesel engines.
Three way converter unlimited
Such a converter unlimited was developed back in 1981. Its main goal is to reduce the amount of harmful substances that enter the environment.
The trilateral type converter unlimited dioxide, as well as hydrocarbons that are not burnt, into water and carbon dioxide. It is also able to convert nitric oxide to oxygen and nitrogen.
converter unlimited are divided into types depending on material of the cartridge. These types are distinguished:
converter unlimited
Ceramic
A design resembling a honeycomb is installe. Neutralizing element made of ceramic is protecte by a platinum-iridium alloy.
What are disadvantages of a ceramic unit?
car owners believe that such a device is too fragile. For example, honeycomb will deteriorate if a converter unlimited hits during riding.
In addition, if you drive through a puddle in a warmed-up car, water droplets will fall onto a red-hot converter unlimited , and it will become worthless. Ceramic dust accumulates inside the device.
It penetrates not only the combustion chamber, but sometimes into the cylinders of the engine. The main advantage of a converter unlimited made of ceramic is its cost.
Metal
The design of such converter unlimited is quite strong and reliable. Metal catalyst is not afraid of mechanical stress.
Made from metal, the shape of a spiral resembling a honeycomb is more elastic. But even such a reliable metal unit has its drawbacks:
- Dot use low quality or leaded fuel.
- Oils and antifreeze can enter the combustion chamber.
- Technical fluids may only be use to flush systems from a reliable manufacturer.
- Re-enriched fuel mixture may cause damage.
- Continuous idling of engine can also lead to malfunction.
Sports converter unlimited
These are metal products with increase throughput compare to conventional metal or ceramic converter unlimited.
Sports catalysts make a car 7–20% more powerful, of course, if a direct-flow exhaust system is mounte on vehicle.
Sports catalysts comply with the environmental requirements of Euro 4 and 5.
Such models have increased reliability.
However, if you intend to purchase such a converter unlimited for a car, the price will be quite high.
What happens to a converter unlimited with time?
Companies claim that they can be use for 100,000-150,000 kilometers. However, in reality, this unit can fail much earlier, especially if you live in a metropolis and constantly stay in traffic jams.
Why may converter unlimited become unusable? The fact is that the vehicle’s catalyst device is a filter. And the filter needs to be change regularly.
The life of term of a converter unlimited will become shorter if ignition system is malfunctioning.
If ignition is set incorrectly, misfires will occur.
As a result, the fuel mixture burns only partially. A huge amount of soot is forme, which accumulates in a catalytic converter. The best solution is to clean it. But this will not help if honeycombs are melte. You can always sell old catalytic converter obtaining substantial price.
Among common causes of catalyst malfunction is damage. If catalytic converter has to deal with low quality fuel, It will not completely burn out. Afterburning process will occur in collector and directly in converter unlimited.
The microparticles clog the filter and air cannot pass through it.
Pay attention to the quality of driving and keep contacts of reliable converter unlimited recycling companies in your phone contacts.
