通过观察发动机散热器(俗称水箱)的种种表现,不仅可以判断冷却系统的工作状况,而且可以分析、推断出发动机其他系统的工作状况。现举几个例子加以说明。 故障现象之一:冷却系统各部分温差较大 用手分别触摸水箱和发动机机体的温度,如果机体温度明显高于水箱,说明节温器有故障,水温达到85℃主阀门仍然打不开或开度很小,造成冷却水无法进行大循
By observing the performance of the engine radiator (commonly known as the water tank), not only can judge the working condition of the cooling system, but also analyze and deduce the working conditions of other engine systems. Here are a few examples to illustrate. Symptom one: the temperature difference between the various parts of the cooling system Touch the temperature of the water tank and the engine body, respectively, if the body temperature is significantly higher than the tank, indicating that the thermostat has a fault, the water temperature reaches 85 ℃ The main valve still can not open or open Degree is very small, resulting in large circulation of cooling water can not be
