This problem occurs during actual engine failures. Most of the time, one cylinder does not work. Sometimes several cylinders may not work. If only one cylinder is not working, the more cylinders there are in the engine, the less obvious this is. the problem will be.
The main manifestations are:
First, the engine vibration amplitude increases, accompanied by abnormal sound, poor acceleration, and the exhaust pipe vibrates obviously, and there is an obvious intermittent feeling as the exhaust gases are vented. Pressing the accelerator will reduce the amplitude.
The oil content in the exhaust gas caused by the lack of cylinders seriously exceeds the standard, and the three-way catalytic converter must burn the exhaust gas containing oil, which will inevitably accelerate the deterioration of the catalyst. converter.
