PROBLEM TO BE SOLVED: To provide an internal combustion engine control device capable of restraining an air-fuel ratio variation in an exhaust gas of flowing out to an exhaust passage caused by blow-by air.SOLUTION: An engine 10 is provided with a port injection valve 22 and a cylinder injection valve 24. An ECU 70 calculates a blow-by air quantity being a quantity of blow-by air uncontributing to combustion, and a cylinder inside air quantity filled in a cylinder out of suction air supplied in the cylinder 12 of the engine 10. The ECU 70 calculates an injection quantity A1 corresponding to a blow-by air quantity, and an injection quantity A2 corresponding to the cylinder inside air quantity. The ECU 70 controls the cylinder injection valve 24 so that the cylinder injection valve 24 performs fuel injection based on the injection quantity A1 in blow-by of the cylinder, and the cylinder injection valve 24 performs the fuel injection based on the injection quantity A2 after finishing the blow-by. |
