調節装置。[Scope of Claim for Utility Model Registration] A circulation circuit for circulating cooling water of an internal combustion engine, a cooling device for cooling the cooling water provided in this circulation circuit, a rotation speed detector for detecting the rotation speed of the internal combustion engine, It is equipped with an inlet temperature detector that detects the temperature of the cooling water on the cooling water inlet side of the circulation circuit, and controls the cooling operation of the cooling system based on the rotation speed of the internal combustion engine and the temperature of the cooling water. A device for controlling temperature includes a bypass pipe that communicates between the cooling water inlet side and the cooling water outlet side of the circulation circuit, a cooling temperature detector that detects the temperature of the cooling water in the cooling device, and a cooling temperature sensor that detects the rotational speed of the internal combustion engine. A rotation speed high/low discrimination section that determines whether the rotation speed is high or low and selects and sets either high rotation mode or low rotation mode according to the discrimination result; A flow path switching section that controls the operation of the cooling device and switches to the cooling device side in high speed mode and switches to the bypass pipe side in low speed mode; An internal combustion engine characterized by comprising: a cooling control section that performs control based on the rotational speed of the internal combustion engine and the temperature detected by the inlet temperature detector, and performs control in a low rotation mode based on the temperature detected by the cooling temperature detector. Engine cooling water temperature control device.
