度制御装置。 Cooling water temperature control for an internal combustion engine, in which a first water temperature sensor and a second water temperature sensor are provided in a cooling water system of the internal combustion engine, and both water temperature monitors turn on and off a heater for heating the cooling water provided in the cooling water system. In the device, the first water temperature sensor acts on the side that conducts the power supply circuit of the heater for heating the cooling water when the temperature of the cooling water is equal to or lower than the lower limit of the control temperature range, and
The second water temperature sensor is a sensor having an on/off temperature difference smaller than at least the control temperature range, and the second water temperature sensor is on the side that cuts off the power supply circuit of the coolant heating heater when the coolant temperature is equal to or higher than the upper limit of the control temperature range. A cooling water temperature control device for an internal combustion engine, characterized in that the first water temperature sensor is a sensor that operates and maintains a state until the first water temperature sensor acts to cut off a power supply circuit of a heater.
