Background

A diesel engine is an engine that burns diesel fuel to obtain energy release, and the diesel engine sucks pure air in an intake stroke. When the compression stroke is close to the end, the oil pressure of the diesel oil is increased to more than 10MPa through an oil injection pump, the diesel oil is injected into the cylinder through an oil injector, and the diesel oil is mixed with the compressed high-temperature air in a short time to form combustible mixed gas. Because the compression ratio of the diesel engine is high (generally 16-22), the air pressure in the cylinder can reach 3.5-4.5MPa and the temperature can reach 750-1000K at the same time when the compression is finished (while the mixed air pressure of the gasoline engine at the moment can reach 0.6-1.2MPa and the temperature can reach 600-700K), which greatly exceeds the self-ignition temperature of the diesel oil. Therefore, after the diesel oil is injected into the cylinder, the diesel oil is mixed with the air in a short time and then is immediately ignited and combusted. The air pressure in the cylinder rises to 6-9MPa rapidly, and the temperature also rises to 2000-2500K. Under the push of high-pressure gas, the piston moves downwards and drives the crankshaft to rotate to do work, and the waste gas is exhausted into the atmosphere through the exhaust pipe.
