制御装置。[Claim for Utility Model Registration] A radiator is interposed in the cooling water passage that communicates the inlet and outlet of the water jacket formed in the engine body, and a radiator is provided between the radiator and the inlet of the water jacket. In an engine equipped with a water pump, a low-temperature thermostat is interposed between the radiator of the cooling water passage and the water pump, and a low-temperature thermostat is installed between the water jacket of the cooling water passage and the radiator. A high-temperature thermostat is interposed between the two, and a radiator bypass passage is connected to the cooling water passage, and the outflow side of the radiator bypass passage is connected to the water pump via the temperature sensing section of the low-temperature thermostat. A thermo-bypass passage that communicates with the suction side, and an engine bypass passage that communicates with the inlet side of the radiator with the discharge side of the water pump of the cooling water passage, and that bypasses the high-temperature thermostat with the cooling water passage. A cooling water temperature load control device for an engine, further comprising a negative pressure control valve that opens when intake pipe negative pressure is below a set value.
