PROBLEM TO BE SOLVED: To appropriately reflect the temperature of a combustion chamber in a fuel injection quantity and accurately execute a fuel injection control during warm-up or after warm-up.SOLUTION: An engine 10 includes a cylinder block 12; a cylinder head 14; combustion chambers 16; a fuel injection valve 18; an upstream cooling water passage 20; a downstream cooling water passage 22; a water pump 24; a flow regulation valve 26; an outlet water temperature sensor 30; a head water temperature sensor 32; an ECU 40, and the like. The ECU 40 executes a fuel injection control to set a fuel injection quantity on the basis of a control water temperature and the like. A head water temperature is adopted as the control water temperature during warm-up. Furthermore, after warm-up, the higher temperature out of the head temperature at a time of finishing the warm-up and a latest outlet water temperature is adopted as the control water temperature. It is thereby possible to appropriately reflect a temperature of each combustion chamber 16 in the fuel injection quantity. |
