The exhaust gas removal system is responsible for ensuring that exhaust gases exit through the exhaust pipe in a single flow, quickly and without leaks. The exhaust system consists of several components, one of which is the catalytic converter. The condition in which exhaust gases enter the environment depends on how well the catalytic converter functions.
When the catalytic converter becomes clogged and fails, it creates inconvenience both for driving and for the car itself. The exhaust system can no longer expel gases by any other means. As a result, gases are only partially expelled, are not cleaned sufficiently, and pressure increases between the engine and the plug. Additionally, the system has special sensors that, when such a situation occurs, detect it as a malfunction and reduce engine power.
The catalytic converter can fail for various reasons: low-quality fuel, ignition system malfunctions, mechanical damage that leads to the destruction of the catalyst honeycomb. However, most often the unit breaks and fails to perform its functions due to natural wear, which occurs due to contamination of the honeycomb cavities.
In any case, regardless of the cause of the malfunction, the catalytic converter will have to be completely removed or taken off to install a new one.
How will the vehicle behave without a catalytic converter?
Complete removal of the unit and adaptation of the car to such a state by reflashing the ECU harms the atmosphere. But at the same time, removing this unit helps increase the engine power of the car, reduce fuel consumption, and regular error messages will not appear on the dashboard.
If a clogged or melted catalytic converter is not removed, the exhaust gas will not be able to exit normally and will return to the combustion chamber, which will negatively affect the operation of the engine and the entire exhaust system.
Positive aspects of complete removal:
- improvement of the car's dynamic characteristics;
- reduction in fuel consumption;
- the engine becomes less sensitive to fuel quality;
- the risk of ceramic dust entering the power unit is eliminated.
- negative consequences of complete removal:
- harm to the environment;
- problems with passing technical inspection in EU countries;
- unpleasant exhaust smell;
- loud exhaust system sounds (if the catalytic converter is removed improperly).
Weighing all the pros and cons, one can come to a decision on what to do after the catalytic converter becomes clogged: remove it permanently or replace it with a new one.
Whatever the decision, in any case, you will have to think about where to turn in the already non-working catalytic converter. This issue is easy to resolve by contacting companies that buy up parts that have already served their term, for example here https://autocatalystmarket.com/ua/ru. Buyers not only relieve the car owner of storing a non-working part, but also offer a monetary reward for it, since the catalyst honeycomb contains precious substances.
