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.

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.
