[Claims for Utility Model Registration] An internal combustion engine in which a pump circulates a refrigerant between a refrigerant jacket around a cylinder wall and a radiator, and the radiator is bypassed when the temperature of the refrigerant is lower than a predetermined temperature. In the engine cooling device, the refrigerant jacket is divided into an upper part and a lower part by a partition wall, a communicating passage is formed in the partition wall, and the communicating passage is filled only when the temperature of the refrigerant is lower than a predetermined temperature. Cooling of an internal combustion engine, characterized in that an on-off valve is provided to keep the internal combustion engine in a closed state, and the refrigerant bypassed from the radiator is circulated only to the upper refrigerant jacket when the internal combustion engine is warmed up. Device.
