PROBLEM TO BE SOLVED: To provide an engine control device capable of controlling the optimum state of air-fuel ratio by each cylinder. SOLUTION: An abnormal cylinder determining part 51 determines an abnormal cylinder wherein the fluctuation in the rotation of an engine 1 occurs, on the basis of a rotating angle signal from a rotating angle sensor 26. A rich/lean determining part 52 determines whether an air/fuel ratio is shifted to a rich or lean side with respect to a target air/fuel ratio on the basis of the air/fuel ratio signal from the air/fuel ratio sensor 24. A shift level calculating part 53 calculates the shift level of each cylinder on the basis of the information on abnormal cylinder and the rich/lean information. Each cylinder injection valve correction amount calculating part 54 calculates the amount of correction to the fuel injection amount of a fuel injection valve 9 of each cylinder on the basis of the shift level information of each cylinder, input from the shift level calculating part 53.
