CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To improve a combustion state of each of cylinders at the time of start of an engine even when fuel leaks from fuel injection valves at the time of stop of the engine and there are individual differences in fuel leak amount among the fuel injection valves. SOLUTION: An ECU 1A executes control in the internal combustion engine 50 having the plurality of cylinders and the fuel injection valve 57 provided for each cylinder. The ECU 1A includes a first leak amount calculation means for calculating an accumulated amount Mfof the fuel leaking from the fuel injection valve 57 for each cylinder after the stop of the engine, at least based on an opening gap area Ainjof the fuel injection valve 57, a start time cylinder fuel amount calculation means, a start time fuel injection amount calculation means, a start time air/fuel ratio calculation means for calculating an air/fuel ratio AFR for every cylinder at the time of start of the engine, a second leak amount calculation means for calculating an actual leak amount Mfcofor every cylinder, and an opening gap area updating means for calculating a new opening gap area Ainjcofor every cylinder and updating the opening gap area.
