Under normal circumstances, the working cycle of the engine is four processes, namely, intake, compression, work and exhaust. In the compression process, the mixture of gasoline and air is ignited by the spark plug to form kinetic energy to push the piston. The reason for the fire of a cylinder of the engine is that the kinetic energy is not enough to push the piston due to the incorrect ignition in the compression process. Once the engine catches fire, the most intuitive feeling is that the engine shakes, the engine power is insufficient, the acceleration is weak, and it may even lead to flameout.
