What are the causes of engine backfire and ignition?

The cause of engine backfire and ignition in Pacific Auto Network may be the fault of oil circuit or air intake system. The oil circuit fault is mainly caused by too little fuel injection from the injector, mainly due to the low oil pressure and the blockage of the injector; 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.

Engine tempering: engine tempering, also known as? Countercurrent? . Simply put, the mixture after combustion failed to be discharged from the combustion chamber in time before and after the exhaust stroke, but ran to the intake pipe through the intake valve to ignite some fresh mixture, accompanied by? Bang bang? Fault phenomenon of abnormal sound.

Engine deflagration: when the mixture is too rich, a part of unburned or excess combustible mixture will be discharged into the exhaust pipe with the exhaust gas, and it will explode when it meets Mars or overheated exhaust gas in the exhaust pipe. Shoot? .

Hazards that may be caused by tempering:

1, Throttle damage: Throttle damage may lead to insufficient engine power, flameout during driving, idling, engine failure to start, and fault code will report throttle damage.

2. The connecting pipe breaks free (even bursts), which can be seen by naked eyes; The related fault phenomenon is that the vehicle has insufficient power or the vehicle cannot be started.
