How does a diesel engine work?

The working principle of a diesel engine is based on the combustion process of diesel fuel, which is divided into several important steps: 1.Intake process: When a diesel engine is in operation, air is first drawn in through the intake valve. At this time, no fuel is added, only pure air into the cylinder. 2.Compression: The air entering the cylinder is compressed by the piston moving upwards. The compression ratio is usually high, which causes the temperature inside the cylinder to rise...
