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.

Diesel generators have many advantages, such as multiple capacity levels per unit, compact supporting equipment structure, flexible installation location, high thermal efficiency of the generator, low fuel consumption, fast starting, simple maintenance and operation, and low comprehensive cost. Therefore, they are widely used in various fields such as mines, marine ports, outdoor construction sites, municipal machinery, building construction, and aquaculture.

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.

As an efficient and reliable power generation equipment, diesel generators play an important role in various fields. We should fully understand its characteristics and working principle, use and maintain it correctly, to ensure its stable and safe power support for us. Diesel generators are widely used in factories, mines, docks and other places that require stable and reliable power supply. Diesel generators serve as backup or main power sources to ensure the normal operation of production activities.

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.
