What are the functions of the pulleys on the engine?

An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. For example, the internal combustion engine usually converts chemical energy into mechanical energy. Engines are suitable for both power generation units and can refer to the entire machine including power units (e.g. gasoline engines, aero engines). The pulley belongs to the disc hub parts, generally the relative size is relatively large, and the manufacturing process is generally based on casting and forging.

The role of the engine pulley is to transmit power, when there is an accessory belt, the power output of the crankshaft is transmitted to the air conditioning compressor, power steering pump, water pump, generator, etc.; Timing belt, which transmits the power output from the crankshaft to the camshaft and drives the timing system; There are some engines with a balance shaft, which is also driven by a belt.
