Marine diesel engines are generally divided into high-speed, medium-speed, and low-speed diesel engines, and can be divided into the main engine and auxiliary engine according to their role in ships. The main engine is used as the propulsion power of the ship, and the auxiliary engine is used to drive the generator, air compressor or water pump, etc.
