Basic structure and principle of diesel generator sets

The advantages of diesel engines are high torque and good economic performance. The working process of a diesel engine has many similarities with that of a gasoline engine. Each working cycle also undergoes four strokes of intake, compression, work, and exhaust. However, since the fuel for diesel engines is diesel, its viscosity is larger than that of gasoline, it is not easy to evaporate, and its auto-ignition temperature is lower than that of gasoline. Therefore, the formation and ignition of combustible mixture are different from those of gasoline engines. The main difference is that the mixture in the cylinder of a diesel engine is compression-ignited rather than ignited. When the diesel engine is working, the air entering the cylinder is air. When the air in the cylinder is compressed to the end point, the temperature can reach 500-700 ° C, and the pressure can reach 40-50 atmospheres. When the piston approaches the top dead center, the fuel injector of the fuel supply system injects fuel into the cylinder combustion chamber at a very high pressure in a very short time. The diesel fuel forms fine oil particles, which are mixed with high-pressure and high-temperature air, and the combustible mixture burns by itself. The violent expansion produces explosive power and pushes the piston down to work. At this time, the temperature can reach 1900 to 2000 ° C, the pressure can reach 60 to 100 atmospheres, and the generated torque is very large, so the diesel engine is widely used in large diesel equipment.
