Diesel Generator Sets refers to a power generation device that uses diesel as the main fuel and a diesel engine as the primary power source to drive an AC generator, converting mechanical energy into electrical energy. Composed of a diesel engine, an AC generator, and a control system.

Classification of Diesel Generator Sets:

1. The units can be classified according to their different purposes, including fixed diesel generator sets, marine diesel generator sets, and special diesel generator sets; Among them, special diesel generator sets can be divided into closed diesel generator sets, mobile diesel generator sets, and emergency diesel generator sets, etc; Mobile diesel generator sets can be further divided into trailer mounted diesel generator sets, vehicle mounted diesel generator sets, manual diesel generator sets, etc;

2. According to the engine speed, the units can be classified into high-speed diesel generator sets (speed greater than 1200r/min, four stroke), medium speed diesel generator sets (speed 400-1000r/min, four stroke), and low-speed diesel generator sets (speed less than 400r/min, two-stroke, commonly used in large power plants).
