Phenomenon and causes of cylinder failure

This problem occurs in actual engine failures, mostly because one cylinder does not work, and sometimes there may be multiple cylinders that do not work. If only one cylinder does not work, the more the total number of engine cylinders, the less obvious the performance.

The main performance is:

First of all, the engine vibration amplitude increases, accompanied by abnormal sound, weak acceleration, obvious exhaust pipe jitter, and obvious intermittent feeling when exhausting. When the accelerator is in neutral, the amplitude will decrease.

Because of the lack of cylinder, the oil content in the exhaust gas seriously exceeds the standard, and the three-way catalyst will burn the oily exhaust gas, which will inevitably accelerate the deterioration of the catalyst.
