A Diesel Generator Set (DGS) is a complete power equipment that uses diesel as fuel. It converts the chemical energy of diesel into mechanical energy through a diesel engine (compression-ignition internal combustion engine), which then drives a synchronous generator to convert mechanical energy into electrical energy.

Characterized by independent power supply, rapid startup, and stable operation, it can provide continuous or emergency electrical energy without relying on the power grid. As a critical power supply equipment for industrial production, emergency support, and outdoor operations, it is widely used in scenarios such as power outages, inadequate power grid coverage, or where high reliability of power supply is required.
