Diesel engines are engines that burn diesel fuel to obtain energy release. The diesel engine is invented by German inventor Ludafu diesel in 1892, and in order to commemorate the inventor, the diesel is represented by his surname, and the diesel engine is also called as a diesel engine.
The oil engine has the advantages of large torque and good economic performance. The working process of a diesel engine is much the same as that of a gasoline engine, and each working cycle also goes through four strokes of intake, compression, power and exhaust. However, the fuel for diesel engine is diesel oil, which has higher viscosity than gasoline and is not easy to evaporate, and its self-ignition temperature is lower than gasoline, so the formation and ignition mode of combustible mixture are different from that of gasoline engine. The difference is mainly that the mixture in the cylinder of the diesel engine is compression ignited, not ignited. When the diesel engine works, air enters the cylinder, and when the air in the cylinder is compressed to the end point, the temperature can reach 500-700 ℃, and the pressure can reach 40-50 atmospheric pressures. When the piston is close to the top dead center, the fuel spray nozzle of the fuel supply system sprays fuel to the combustion chamber of the cylinder in a very short time at a very high pressure, diesel oil forms fine oil particles and is mixed with high-pressure and high-temperature air, combustible mixed gas is combusted automatically, and explosive force is generated by violent expansion to push the piston to do work downwards.
