PROBLEM TO BE SOLVED: To properly define a time for prohibiting reduction correction out of increase correction and the reduction correction corresponding to a change of a fuel amount adhering on a wall face of an intake pipe.SOLUTION: When an engine is non-load operated after an engine start, a prescribed time tb1 is set to a threshold tbref (S220), and when the engine is load-operated after the engine start, a prescribed time tb2 which is shorter than the prescribed time tb1 is set to the threshold tbref (S230). Then, when a time tb after the completion of the start-time injection of the engine is shorter than the threshold tbref, the reduction correction of wall-face adhesion correction is prohibited (S250, S260), and when the time tb reaches the threshold tbref or longer, the reduction corresponding of the wall-face adhesion correction is permitted (S270, S280).SELECTED DRAWING: Figure 4 |
