PROBLEM TO BE SOLVED: To optimally control one cylinder by issuing control command based on a control value provided according to this time value of an engine parameter at that time, when a present stage count value matches an execution stage number to be controlled according to the engine parameter. SOLUTION: A cell changeover routine is executed for each coming of a timing pulse. First, when a stage counter value stg is equal to 4, engine rotation speed Ne and throttle valve openingθat this time are taken in (S1, S2). According to a map where a coordinate point in a system of longitudinal and transverse coordinates of respectively the rotation speed Ne (i) and the throttle valve openingθ(j) is set as a cell Cij, the Cij (4) of a fourth cylinder is determined (S3). Next, a calculated stage FISTG (4) of injection amount for the fourth cylinder is retrieved from the map. Similarly, first, third, and second cylinders can be retrieved. Thus, control operation can be executed.
