      CONSTITUTION: At a step 302, the sum total S=ΣQi of injection quantity correction items Qi for each cylinder is calculated. Next, at a step 303, if an absolute value |S| is smaller than a threshold value δ, a process comes to an end without doing nothing as it is. If the absolute value is larger than the threshold value δ, it goes forward to the next step 304 in order to add a compensation value to the injection quantity correction item Qi. At steps 304W306, according to positive and negative codes of the said sum total S, a fixed compensation value Δ is added or subtracted to or from each injection quantity correction item Qi. As a result, the absolute value |S| of the sum total S of injection quantity correction items Qi is compensated so as to be reduced. Thus, an uncomfortable variation in engine revolution is checked.
