Is it easy to explode when the automobile exhaust system is blocked?

When the exhaust pipe is blocked, there will be poor exhaust at this time, which will lead to the decrease of intake air in the intake pipe. The decrease of intake air means that the automobile engine burns abnormally, which will lead to the decrease of engine power. If the owner of the car suddenly has an unstable idle speed of the engine and is unable to refuel in the middle of driving, the exhaust pipe is generally blocked, and of course it may be due to engine failure.

We already know that if the exhaust pipe is blocked, the engine power will drop to a certain extent, so the owner will choose to step on the accelerator deeply in order to have a higher speed. At this time, the throttle will open, and the ECU will detect the opening of the throttle and control the gearbox for forced downshift. Therefore, if the owner drives, it is usually because the exhaust pipe is blocked.

When the engine exhaust is not smooth, part of the exhaust gas will stay in the cylinder, diluting the mixed steam and slowing down the combustion speed. When the intake valve is opened, the mixed steam is still burning. Therefore, the mixed steam after combustion will flow back into the intake pipe through the open intake valve, causing tempering.

When the engine accelerates or closes the throttle, the owner will hear the noise of the exhaust pipe. When the owner hears the abnormal sound of the exhaust pipe, he should pay attention. This means that the three-way catalytic converter is damaged and the exhaust pipe is blocked, which will not only lead to excessive exhaust emissions, but also lead to other problems of the vehicle.
