Diesel engine Deutz

The advantages of diesel engines are high torque and good economic performance. The working process of diesel engines has many similarities with gasoline engines, and each working cycle also goes through four strokes: intake, compression, work, and exhaust. However, because the fuel used in diesel engine is diesel, its viscosity is greater than that of gasoline, it is not easy to evaporate, and its spontaneous combustion temperature is lower than that of gasoline, so the formation and ignition method of combustible mixture are different from gasoline engines. The main difference is that the mixture in the cylinder of a diesel engine is compression-ignited, not ignited. When the diesel engine is working, it is air that enters the cylinder, and when the air in the cylinder is compressed to the end, the temperature can reach 500-700 °C, and the pressure can reach 40-50 atmospheres. When the piston is close to the dead center, the fuel injector of the oil supply system injects fuel into the cylinder combustion chamber in a very short time with extremely high pressure, the diesel forms fine oil particles, mixed with high-pressure and high-temperature air, the combustible mixture burns on its own, violently expands to produce explosive force, and pushes the piston downward to do work, at this time the temperature can reach 1900-2000 °C, the pressure can reach 60-100 atmospheres, and the torque generated is very large, so diesel engines are widely used in large diesel equipment.
