冬季天气寒冷,为了减少天天放冷却水的麻烦和防止忘记放冷却水而冻坏机体,可在发动机的冷却系统加注防冻液。 目前,常用的防冻液主要有乙二醇、乙醇、甘油、甘油一乙醇等,由于这些防冻液的成分及配制比例不同,其凝点(凝固温度)也有所不同。因此,选用时应根据当地的气温条件、作业区域范围及环境条件等选用适宜的防 Winter cold weather, in order to reduce the daily chill water and prevent forgetting to put the cooling water to freeze the body, the engine cooling system can be antifreeze. At present, commonly used antifreeze mainly glycol, ethanol, glycerol, glycerol, such as ethanol, due to the composition of these antifreeze and the preparation of different proportions, the freezing point (freezing temperature) is also different. Therefore, the selection should be based on local temperature conditions, the scope of work area and environmental conditions, such as the selection of suitable anti-
