  There are many kinds of marine engine s, such as marine diesel engines   and marine coal-fired generators, etc. FAW  will briefly introduce the working principle of marine diesel engines for you to have a deeper understanding of this kind of marine engine. 　　 As we all know, the main use of marine diesel engine is to provide power for ships, and its working principle is as follows. 　　 Fresh air is pumped into the pump and compressed by the piston through very high pressure, when the air is well compressed, as the temperature rises allowing it to ignite the atomised fuel in the cylinder. The combustion of the fuel adds heat to the air in the pump, which expands and allows the engine's pistons to do work on the crankshaft, which then drives the ship's propeller through the other shafts.   　　 A marine engine's operating cycle consists of two fuel injections. Some four-stroke diesel engines must be completed by four strokes of the piston, i.e. suction, compression, expansion
