Description

Diesel engine circulating cooling device for construction machinery

Technical Field

The invention relates to the field of diesel engines, in particular to a diesel engine circulating cooling device for construction machinery.

Background

The diesel engine has the advantages of high power and good economic performance. The working process of a diesel engine has many places same as that of a gasoline engine, and each working cycle also goes through four strokes of air intake, compression, work application and air exhaust. However, because the fuel used for diesel engine is diesel oil, its viscosity is greater than that of gasoline, it is not easy to evaporate, and its self-ignition temperature is lower than that of gasoline, so that the formation and ignition mode of combustible mixed gas are different from that of gasoline engine, and the difference is mainly that the mixed gas in the cylinder of diesel engine is compression-ignited, but not ignited. When the diesel engine works, air enters the cylinder, high temperature and high pressure are generated when the air in the cylinder is compressed to a terminal point, when the piston is close to a top dead center, a high-pressure pump on the engine sprays diesel into the cylinder at high pressure, the diesel forms fine oil particles and is mixed with the high-pressure and high-temperature air, the diesel mixed gas is combusted automatically, expands violently to generate explosive force to push the piston to do work downwards, and higher heat and air pressure are generated at the moment to generate great power. After the diesel engine operated for a period of time, whole device all can become very hot, consequently need carry out cooling to the diesel engine and handle, and current diesel engine cooling device is mostly through connecting a water jacket on the cylinder body, and the water jacket is connected with the water tank again and is cooled down, and such setting can not carry out comprehensive cooling to the diesel engine, makes the temperature difference on diesel engine surface great, has influenced diesel engine life.
