The temperature of the generator set rapidly increases when the volume of the diesel generator set decreases, reaching the ignition point of the diesel. Diesel fuel is ignited, the mixture of gases burns violently, the volume expands rapidly, and the piston is pushed downwards, which is called 'work done'.
Each cylinder works in a certain order, and the thrust acting on the piston is converted into the force that drives the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. Using the principle of 'electromagnetic induction', the generator will output induced electromotive force, which can generate current through a closed load circuit. This only describes the most basic working principle of the generator set. To obtain a usable and stable power output, a series of diesel engine and generator control, protection devices, and circuits are also required.
