摘要： PROBLEM TO BE SOLVED: To provide an engine cooling device capable of warming up an engine main body satisfactorily.
SOLUTION: A cooling circuit R in which cooling water for cooling an engine 1 circulates is provided with a flow-in passage 7 for letting cooling water flow in from one side in the direction of cylinder arrangement in a water jacket 4 of a cylinder head 2 and a flow-out passage 8 for letting cooling water in the water jacket 4 flow out from the other side in the direction of cylinder arrangement. Warm cooling water in the cooling circuit R is stored in a heat storage vessel 14 by keeping it warm and flows into the water jacket 4 of the cylinder head 2 through supply passages 15 provided by corresponding to each cylinder when starting the engine from a cold condition. An opening and closing valve 17 closed to shut off the flow-out passage 8 when cooling water in the heat storage vessel 14 flows into the water jacket 4 is provided in the flow-out passage 8. For this reason, cooling water flowing into the water jacket 4 from each supply passage 15 remains easily in the water jacket 4.

摘要： PROBLEM TO BE SOLVED: To provide a cooling device for an internal combustion engine capable of suppressing the reduction of controllability when controlling a temperature of cooling water to a target value during feedback control of a flow rate control valve.
SOLUTION: During the feedback control of the flow rate control valve 7, lower limit guard is performed concerning a degree of opening of the valve 7. Consequently, the adjustment of degree of opening of the flow rate control valve 7 is not performed in an opening degree region in the vicinity of full closing where change of a water temperature at an engine exit becomes excessively great or little for change of degree of opening. Moreover, when the tendency of the water temperature at the engine exit is inverted between ascent tendency and descent tendency during the feedback control, a degree of opening of the flow rate control valve 7 is changed by a skip amount S so that water temperature at the engine exit approaches the target value.
