Diesel Generator


The diesel generator is composed of a diesel engine and a generator, and the diesel engine is used as the power to drive the generator to generate electricity.


A diesel generator consists of cylinders, pistons, cylinder heads, intake valves, exhaust valves, piston pins, connecting rods, crankshafts, bearings, and flywheels. The diesel engine of the diesel generator is generally a single-cylinder or multi-cylinder four-stroke diesel engine.

Working Principle

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 squeeze of the piston, the volume is reduced and the temperature rises rapidly, reaching the ignition point of diesel. The diesel is ignited, the mixed gas burns violently, and its volume expands rapidly, pushing the piston down, which is called ‘work’. Each cylinder performs work in a certain order, and the thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. Install the brushless synchronous alternator coaxially with the crankshaft of the diesel generator, and then 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 induced electromotive force through a closed load circuit. Can produce an electric current. In short, the diesel generator drives the generator.
