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.
