防冻液(anti-freeze solution)是一种加入冷却水中以防止水结冰的溶液。防冻液,又称不冻液或防冻抗沸冷却液作为一种发动机冷却系统的冷却介质。因为水结冰时,其体积膨胀原体积之9%,故发动机内冷却水结冰时,膨胀力足使气缸体与水箱破裂,所以在冬天时,在冷却水中加防冻液在汽车所遭遇的最低温度时,仍能保持水循环自如,而且对冷却系能防过热、结垢与无腐蚀作用,经使用相当时期,仍不失其防冻能力。如何正确使用防冻液对发动机能否保持正常的工作和良
Anti-freeze solution is a solution that is added to cooling water to prevent it from freezing. Antifreeze, also known as antifreeze or antifreeze anti boiling oil as a cooling medium for the engine cooling system. Because water ice, its volume expansion of the original volume of 9%, so the engine cooling water freezing, the expansion force enough to make the cylinder block and tank rupture, so in winter, add antifreeze in the cooling water encountered in the car The lowest temperature, still able to maintain water cycle freely, and the cooling system to prevent overheating, scaling and non-corrosive effect, the use of a considerable period of time, still without losing its antifreeze ability. How to properly use antifreeze on the engine can maintain normal work and good
