汽车发动机冷却系内加注或放出冷却水,看来是小事,但若加放冷却水不当,不仅影响冷却系本身的正常工作,而且还缩短发动机的使用寿命,严重时会造成事故。因此,必须引起重视。 (1)汽车发动机冷却系应加注软水。汽车发动机若长期使用硬水,冷却系内壁会形成水垢,水垢的导热能力是同样厚度的黄铜导热能力的1％,会严重妨碍发动机的散热。用来加注冷却
It seems a trivial matter to add or discharge cooling water into the cooling system of the automobile engine. However, improper cooling water will not only affect the normal operation of the cooling system itself, but also shorten the service life of the engine and cause serious accidents. Therefore, we must pay attention. (1) automobile engine cooling system should be filled with soft water. Long-term use of automotive engine hard water, the cooling system will form the inner wall scale, scale thermal conductivity is the same thickness of the brass thermal conductivity of 1%, will seriously hamper the engine cooling. Used to raise the cooling
