为了控制冷却风扇的转速和百叶窗的开度来调节进入散热器的空气量 ,从而获得适当的机油和冷却水温度 ,保证柴油机正常工作 ,内燃机车上设置了温度调节器 (也称作温度控制阀 )。温度调节器一旦失效 ,就将引起润滑油和冷却水温度过高而导致温度继电器动作 ,让柴油机卸载 ,使机车 In order to control the cooling fan speed and shutter opening to adjust the amount of air into the radiator, so as to obtain the appropriate oil and cooling water temperature, to ensure the normal operation of the diesel engine, diesel locomotive set temperature regulator (also known as temperature control valve ). Once the thermostat fails, it will cause the temperature of the lubricating oil and cooling water to be too high, which will cause the temperature relay to operate and allow the diesel engine to unload so that the locomotive
