The generating process of piston knock noise is thoroughly analyzed by the study of pistonmotion state and knock process with the engine at the rated engine speed.
进一步分析了发动机额定转速下，活塞的运动姿态和敲击过程，揭示出活塞敲击噪声的产生过程。

The crankshaft, regarded as the "backbone" of the engine, serves to change the reciprocating motion of the piston into rotary motion and handles the entire power output.
Equivalent to sing the role of round piston reciprocating piston compressor, when the satellite gear shafts relative motion at the Beaufort, the closed volume decreases, the gas being compressed.
