About 30% to 33% of the heat released by fuel combustion in diesel engines is dispersed through cylinder, cylinder cover and piston components.In order to dissipate the heat, a sufficient amount of cooling medium is required to force continuous flow through the heated parts, and the normal stable temperature of the heated parts is ensured by cooling.Therefore, the cooling system is installed in most diesel engines to ensure sufficient and continuous cooling medium flow and proper cooling medium temperature.

The function and mode of cooling

From the perspective of energy utilization, the cooling of diesel engine is an energy loss that should be avoided, but it is necessary to ensure the normal operation of diesel engine.Diesel engine cooling has the following functions: first, cooling can keep the working temperature of the heated parts within the allowable limit of the material, thus ensuring sufficient strength of the heated parts at high temperature;Secondly, cooling can ensure the appropriate temperature difference between the inner and outer walls of the heated parts and reduce the thermal stress of the heated parts.In addition, cooling can also guarantee the proper clearance of moving parts such as piston and cylinder liner, and the normal working state of oil film of cylinder wall working face.These effects of cooling are achieved through the cooling system.In the management, both the cooling requirements of the diesel engine should be taken into account, so that the diesel engine is neither over-cooled nor overheating due to lack of cooling.In modern times, the research on adiabatic engine was carried out at home and abroad to minimize cooling loss and make full use of combustion energy.At present, the diesel engine cooling method is divided into forced liquid cooling and air cooling.Most diesel engines use the former.
