At present, the general diesel generator set is powered by a four-stroke reciprocating piston diesel engine. The function of the diesel engine fuel supply and speed control system is to inject a certain amount of diesel into the combustion chamber at a certain pressure for a certain period of time and mix with air. In order to burn to do work. It is mainly composed of diesel tank, fuel transfer pump, diesel filter, fuel injection pump (high pressure fuel pump), fuel injector, governor, etc.

The function of the lubrication system is to deliver the lubricating oil to the friction surface of the moving parts of the diesel generator set, which plays the role of anti-friction, cooling, purification, sealing and rust prevention to reduce frictional resistance and wear and take away the heat generated by friction , So as to ensure the normal operation of the diesel engine. It is mainly composed of an oil pump, an oil filter, an oil radiator, various valves and lubricating oil passages.

The function of the cooling system is to transfer the heat of the heated parts of the diesel engine to keep the diesel engine working at the most suitable temperature to obtain good economy, power and durability. The cooling system is divided into water cooling and air cooling. Most diesel engines use water cooling systems, which use water as the cooling medium. There are also a few diesel engines using air-cooled systems. Air cooling is also called air cooling. It uses air as a cooling medium to transfer the heat from the heated parts of the diesel engine. This cooling method is composed of a fan and a wind deflector. In order to increase the heat dissipation area, cooling fins are usually cast on the cylinder head and cylinder block.

Diesel engines cannot start on their own, and must use external force to make them run on fire and burn to achieve self-operation. Therefore, the diesel engine is equipped with a dedicated starting device. Diesel engines started by hand crank have starting claws; those started by motors are equipped with starting motors. The compressed air starting device is equipped with compressed air starting device.
