How to deal with the tempering of automobile exhaust pipe?

1, the engine runs normally, divided into four steps: intake, compression, work and exhaust. Tempering;

2. Generally speaking, in the cylinder, after the piston does a good job, the burnt exhaust gas should be discharged from the exhaust pipe, but due to some fault, the exhaust valve has been closed, so it is impossible to discharge the exhaust gas, or it is too late to discharge the exhaust gas;

3. Then the exhaust gas will be discharged from individual cylinders in the cylinder head, crankcase, carburetor, throttle and other places, which is what we often call "backward flow", that is, engine tempering. When the throttle is released to slow down, tempering is more frequent.

Oil circuit failure is mainly caused by too little fuel injection from the injector, which is mainly caused by the following reasons: the oil pressure is too low; The fuel injector is blocked. The fault of the air intake system is mainly caused by the excessive air intake, which is mainly caused by the fault of the sensor controlling the air intake; Air leakage in the intake manifold.
