The principle of diesel generator
Dec 06,2022
The rotation of the crankshaft of the diesel engine will drive the generator to rotate and generate electricity. The generator has a DC generator and an AC generator.
In the cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel sprayed from the fuel injector. Under the upward extrusion of the piston, the volume shrinks and the temperature rises rapidly to reach the ignition point of diesel. When the diesel oil is ignited, the mixed gas burns violently, and the volume expands rapidly, pushing the piston down, which is called 'work'. The cylinders perform work in a certain order, and the thrust acting on the piston becomes the power to drive the crankshaft through the connecting rod, thereby driving the crankshaft to rotate. Install the brushless synchronous alternator coaxially with the crankshaft of the diesel generator, and the rotation of the diesel generator can be used to drive the rotor of the generator. Using the principle of 'electromagnetic induction', the generator will output an induced electromotive force, which is passed through the closed load circuit. current will be generated.
The package combination of diesel engine, generator and various auxiliary devices (such as base, roof, sound attenuation, control system, circuit breaker, jacketed water heater and starting system) is called "generator set".
