Is there any danger of failure in the exhaust system?

The failure of the exhaust system is dangerous.

If it is a fuel problem, the catalyst will be poisoned and its activity will decrease, and sulfur, phosphorus and other substances will be produced in the three-way catalyst, which will lead to the decline of vehicle performance. It will also lead to poor combustion effect and serious carbon deposition in the engine, which will lead to a decrease in engine power and an increase in fuel consumption, and even an engine knock in severe cases.

Due to the use of fuel oil or lubricating oil, the catalytic converter is poisoned, the activity is reduced, and the catalytic conversion efficiency is affected. The complex and deposit of sulfur and phosphorus are produced in the three-way catalytic converter, which deteriorates the performance of the automobile, leading to the decline of power performance, the increase of fuel consumption and the deterioration of emissions.

Exhaust system failure will affect fuel consumption, and poor combustion effect for a long time will lead to excessive carbon deposition, which will directly lead to engine damage. The failure of engine exhaust system will affect the safety of the car during driving and reduce the service life of the engine.

Fault of engine exhaust system and its treatment method

1, there is serious carbon deposit inside the throttle or engine, and the engine computer will detect the signal and the fault light will be on. Clean the throttle or engine interior. If it's serious, you need to change the throttle.

2. The fuel used by the vehicle is of poor quality or deteriorated after being parked for a long time, so it needs to be replaced.

3. One of the oxygen sensors before and after the three-way catalytic converter is damaged, or the sulfur, phosphorus and other substances produced by the three-way catalytic converter are poisoned. You need to go to a 4s shop or a repair shop to find a professional to detect and repair.

4. If the exhaust fault light is on, the vehicle can't start when the engine is turned off, mostly because the fuel pump or ignition device is out of order, and it is necessary to replace the new fuel pump or accessories of ignition device such as spark plug and ignition coil.
