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 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 at low temperature, the thermostat valve is closed, the cylinder cover water all from the thermostat bypass into the pump, when the water temperature up to 70
