汽车散热器水垢对发动机的正常工作有如下影响: ①水垢过多,会减少冷却系的容积,影响冷却水的循环量; ②水垢的导热系数低,散热效果差,水垢过多会使发动机温度升高,能诱发表面点火和爆震燃烧等故障; ③水垢脱落物,随冷却水流动时,进入水泵会影响水泵正常运转,甚至卡住水泵叶轮; Car radiator scale on the normal work of the engine has the following effects: ① too much scale, will reduce the cooling system volume, affecting the cooling water circulation; ② scale thermal conductivity is low, the cooling effect is poor, too much scale will make the engine temperature Rise, can trigger surface ignition and knock combustion and other failures; ③ scale off objects, with the cooling water flowing into the water pump will affect the normal operation of the pump, and even stuck pump impeller;
