converter unlimited are important parts of the exhaust system. converter unlimited have two functions:
to purify exhaust gases before being emitted into the atmosphere and to reduce additional resistance. The converter unlimited is located on the underbody of a vehicle between the muffler and exhaust manifold. converter unlimitedis installed on both gasoline and diesel engines. That means a catalytic converter is used for each type of transport with internal combustion. Drivers must control the work of the converter unlimited since motor power depends on it. Bad converter unlimited leads to increased fuel consumption and lower vehicle dynamics. The damaged and old converter unlimited has to be professionally recycled by specialized companies
What are the symptoms of a bad converter unlimited?
At first symptoms, accurate converter unlimited check can be done independently or in the care service. Drivers, even with little experience, will be able to easily determine if there is a malfunction in the exhaust system, which is most often associated with the converter unlimited.
- If exhaust gas began to pass poorly into the tube, this will affect the “behavior” of the auto. It will hardly gain speed due to problems with the converter unlimited. In this case, the problem is felt up to a certain point, which depends on the degree of contamination of the converter unlimited .
- When accelerating along a suburban highway, transport will slowly increase speed in low gears, and when shifting to higher, it will start working as usual. A good reason to check catalytic converter.
- There may be a feeling that there is a heavy load in the back of a car (catalyst location), which is why acceleration is slow. This is the converter unlimited that tries to show drivers important signs.
- Check Engine light is on. If a converter unlimited is bad, some electronic control units light a lamp with a request to check so that the driver understands that there is a malfunction.
- An error message P0420 may light upon the onboard computer(typical catalytic converter sign) when the catalyst goes bad. A problem with the efficiency of the motor.
- Increased fuel consumption, caused by the converter unlimited. A bad converter unlimited may increase fuel consumption. Please note that an increase in consumption indicates a malfunction in the exhaust system only if there is a problem with slow speed gain. If the converter unlimited is badly damaged or clogged, the car may not start. Or the motor will start, but stall after a few seconds of operation.
Why do converter unlimiteds get bad?
If there are problems with a converter unlimited, it is covered with dirt or deformed. Most often, the following reasons lead to failure of the converter unlimited and urgent need to get rid of the old catalyst.
Remember about things that cause problems with the converter unlimited
- Low-quality fuel. If the fuel-air mixture does not have time to completely burn out in the combustion chamber, it burns out in the manifold or converter unlimited. This leads to the fusion of elements of the exhaust system. As result combustion products get stuck in theconverter unlimited , thereby preventing air from passing at the required speed;
- Bad converter unlimited. If a non-original converter unlimited is used, then there is a great risk of acquiring a model where cells have a small diameter, because they quickly clog by combustion products. Such a problem can be observed with catalysts in cars designed for the American market, where fuel quality is higher and fewer combustion products are left from it. converter unlimited with small “cells” are installed in such vehicles.
- Problems in motor. It leads to an increase in products of combustion in the exhaust. In this case, only professional diagnostics of the catalytic converter is needed. Because a clogged converter unlimited is often a symptom of a malfunction.
- Driving bad roads. With regular driving on bad roads, converter unlimited can get mechanical damage. The impact will lead to the destruction of converter unlimited’ honeycombs or their deformation. Also, such a problem can be observed after an unsuccessful attempt to overcome an obstacle.
- Engine overheating. Many drivers, especially in summer, allow driving overheated. During motor overheating, exhaust gases reach extreme temperatures, as a result very high-temperature flow through the catalyst. Melting and destruction of honeycombs of a converter unlimited is guaranteed.
- Increased oil consumption. Drivers who allow increased oil consumption destroy the catalyst. Due to increased oil consumption, converter unlimited cells are coated with a thick layer of soot. Under the influence of high temperatures, soot starts burning and the honeycomb of a converter unlimited melts.
- Faulty lambda sensor causes malfunction of the control unit.
Problems with converter unlimited can lead to the failure of expensive components. It is recommended to eliminate the problem as soon as possible after having a previously diagnosed catalytic converter. Choose a way to evaluate old catalyst and sell It to obtain a good money bonus.
Absence of bad converter unlimited symptoms will provide:
- Increased service life of gasoline and diesel vehicles, thanks to healthy catalyst.
- Extension of resource and normal operation of motors.
- Exclusion of dry start motors with the help of a good converter unlimited.
- Reduction of CO, CH, smoke, vibration, inner noise.
- Increased power and efficiency with clean catalyst.
- Magnitude of octane number of gasoline by 3-5 units.
- Cleaning of soot from candles in presence of defects.
- Improved launch in winter, owing to hardworking converter unlimited
