CA488系列汽油机冷却系为强制循环液冷封闭式,采用管带式散热器、扭矩型硅油风扇离合器、后弯冲压式叶轮水泵与蜡式节温器;设有进气管预热腔,当节温器温度低于83℃时,冷却液流经预热腔升温,使发动机保持在85～98℃温度下工作冷却系设膨胀水箱,能接受散热器中受热膨胀而需放出的冷却液和空气,或提供受冷收缩而需补充的冷却液,使散热器始终充满冷却液.冷却系装机试验表明,冷却、水阻与热量分配等各项特性均达到汽油车的设计指标;部件台架试验表明,各部件经历500小时可靠性试验,均未出现任何损坏,达到设计使用要求.
CA488 series gasoline engine cooling system is a forced circulation liquid-cooled closed tube-type radiator, torque-type silicone oil fan clutch, backward bending impeller pump and wax thermostat; with intake manifold preheating chamber, when the junction temperature When the temperature is lower than 83 ℃, the cooling liquid flows through the preheating chamber to heat up, keeping the engine working at the temperature of 85-98 ℃. The cooling system is equipped with an expansion tank, capable of receiving the coolant and air to be released by the heat expansion in the radiator, Or to provide cold shrinkage to be supplemented by the coolant, so that the radiator is always filled with coolant. Cooling system installed test showed that the cooling, water resistance and heat all the characteristics of gasoline engines meet the design specifications; parts bench test shows , Each component experienced 500 hours reliability test, did not appear any damage, to meet the design requirements.
