PROBLEM TO BE SOLVED: To provide an internal combustion engine control device for well avoiding the worsening of combustion resulting from the back flow of exhaust gas in an internal combustion engine which has a fuel adding valve arranged in an exhaust passage near an exhaust valve. SOLUTION: In an exhaust port 20 of the exhaust passage 16 for a #4 cylinder, the fuel adding valve 26 is provided for adding fuel into the exhaust passage 16. An exhaust variable valve train 58 is provided for changing a valve timing for the exhaust valve 56 (Fig.2). When an execution request for fuel addition from the fuel adding valve 26 is detected and an execution request for exhaust valve early opening control using the exhaust variable valve train 58 is detected, exhaust valve early opening control is not performed for a cylinder located close to the fuel adding valve 26.
