Although diesel generator sets have lower power, they are widely used in mining, railways, field construction sites, road traffic maintenance, as well as factories, enterprises, hospitals and other departments due to their small size, flexibility, lightness, complete supporting facilities, and ease of operation and maintenance. Diesel generator sets are used in places where there is no connection to the grid, or as emergency power sources in the event of grid failures, as well as for more complex applications such as peak tripping, grid support, and grid output.

Diesel generator is a small power generation equipment that refers to a power machinery that uses diesel as fuel and diesel engine as the prime mover to drive the generator to generate electricity. The entire unit is generally composed of diesel engine, generator, control box, fuel tank, starting and control battery, protection device, emergency cabinet and other components. It can be used for daily power generation and emergency power generation in various households, offices, large, medium and small enterprises.

In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injector. Under the upward compression of the piston, the volume shrinks and the temperature rapidly increases, reaching the ignition point of the diesel. After diesel is ignited, the mixed gas burns violently, expands rapidly, and pushes the piston down. This process is called "doing work". The mechanical energy generated by doing work is transmitted to the generator through the crankshaft. The generator uses the principle of "electromagnetic induction" to output induced electromotive force, which can generate current through a closed load circuit.

A diesel generator is a small power generation equipment that uses diesel and other fuels as fuel, and drives the generator to generate electricity through the diesel engine as the prime mover. The entire unit is generally composed of diesel engine, generator, control box, fuel tank, starting and control battery, protection device, emergency cabinet and other components. When using diesel generators, it is also necessary to pay attention to regular maintenance, fuel management, and safe operation to ensure their normal and safe operation.

The diesel generator adopts advanced combustion technology and efficient energy conversion system, which can efficiently convert the chemical energy in diesel into electrical energy, reduce energy consumption, and improve economic benefits. Diesel generators have the characteristics of compact structure, stable operation, and low failure rate, which can operate stably for a long time in harsh environments, ensuring the continuity of power supply.
