Diesel generator set?


The diesel generator set is a kind of power generation equipment based on diesel fuel. The diesel engine is used as the motive power to drive the generator to generate electricity.

A mechanical device that converts kinetic energy into electrical energy and thermal energy. The complete diesel generator set is mainly divided into three parts:


1 diesel engine.


2 generator (ie electric ball).


3 controller.
