In general, the engine is mainly composed of one component, that is, the body component, two major mechanisms (crank linkage mechanism and valve mechanism) and five major systems (fuel system, intake and exhaust system, cooling system, lubrication system and starting system).
Among them, the cooling system as an important part of the engine, play an irreplaceable role.
When the cooling capacity is poor, if the cooling system design is unreasonable, the engine can not be fully cooled and overheated, which will cause abnormal combustion, early ignition and deflagration. The overheating of parts will lead to the reduction of mechanical properties of materials and serious thermal stress, which will lead to deformation and cracks; Too high temperature will also make the oil deterioration, burning and coking, thereby losing lubrication performance, damage the lubricating oil film, resulting in increased friction and wear between parts, which will lead to the engine’s power, economy, reliability and durability. And when there’s too much cooling capacity,
If the cooling capacity of the cooling system is too strong, it will make the cylinder surface oil diluted by fuel resulting in increased cylinder wear, while the cooling temperature is too low, it will make the mixture formation and combustion deterioration, the diesel engine work becomes rough, increase the oil viscosity and friction power, resulting in increased wear between parts, and increase the heat dissipation loss, and then reduce the economy of the engine.
Shacman Automobile will design and optimize the cooling system, according to different engine models and application scenarios to ensure that the engine can maintain a suitable working temperature, under various working conditions and achieve a good balance of performance, reliability and economy.
