Basic principles
In the cylinder of a diesel engine, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected from the fuel injector. Under the upward pressure of the piston, the volume shrinks and the temperature rises, reaching the ignition point of diesel. Diesel is ignited, and the mixed gas burns violently, rapidly expanding in volume and pushing the piston downwards, which is called work. Each cylinder works in a certain order, and the thrust acting on the piston is converted into a force that drives the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate.
