节温器的功用节温器的作用是调整发动机水温，特别是在车辆启动的过程中，它能使发动机温度迅速升高，以减少气缸的磨损。其工作原理是：当冷却水处于低温时，节温器阀门关闭，气缸盖出水全部从节温器旁路流入水泵，当水温高达７０±２℃时，节温器阀门开始张开，此时部分... Thermostat function Thermostat’s role is to adjust the engine water temperature, especially in the process of starting the vehicle, it can make the engine temperature rapidly increased to reduce cylinder wear and tear. Its working principle is: when the cooling water is in low temperature, the thermostat valve is closed, and all the water in the cylinder head cover flows into the water pump from the thermostat bypass. When the water temperature reaches 70 ± 2 ℃, the thermostat valve starts to open, section...
