What is the function of the damping pulley of the engine？

A. Since you also know that it is a "damping pulley", you should know its main function.

Vibration reduction: in order to reduce the impact and vibration caused by the operation of the engine, cut the middle ring into inner and outer parts on the ordinary all iron pulley, and fill the middle (GAP) of the inner and outer parts with rubber, that is, a rubber layer. In this way, the power of the engine is first transmitted to the inner ring of the pulley, then to the damping rubber in the middle layer, and then from the damping rubber to the outer ring. In this way, the vibration and sound of the engine will be reduced in the iron outer ring after the rubber "layer is slow". Thus, the noise is reduced and the vibration (impact force) is alleviated.

B. Transmission transmission power: the power output by the crankshaft is transmitted to the compressor, directional booster pump, water pump and generator.. Etc;

C. The timing belt transmits the power output by the crankshaft to the camshaft to drive the timing system. Some engines with a balance shaft also drive the balance shaft through a belt.
