Diesel engine steel cover convenient to dismouting

Technical Field

The utility model relates to a diesel engine protection technical field specifically is a diesel engine steel casing convenient to dismouting.

Background

The diesel 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 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, the diesel oil forms fine oil particles, the fine oil particles are mixed with high-pressure and high-temperature air, the combustible mixed gas is combusted by itself and expands violently to generate explosive force to push the piston to do work downwards, the temperature can reach 1900-2000 ℃, the pressure can reach 60-100 atmospheric pressures, and the generated torque is very large, so that the diesel engine is widely applied to large-scale diesel equipment.
