<P>PROBLEM TO BE SOLVED: To solve a problem that the acceleration performance at engine acceleration degrades when a fuel amount increase rate is set to 1 (0% increase) in most of the engine operation region including a supercharging area. <P>SOLUTION: A device calculates a first fuel amount increase rate F1 corresponding to a current intake air amount (S11) and a second fuel amount increase rate F2 corresponding to an output mixture ration (S12), and determines whether or not an internal combustion engine is under an acceleration operation state (S14) on the basis of an intake air amount detected by an air flow meter and engine rotation speed. When the internal combustion engine is determined not to be under an acceleration operation state, the first fuel amount increase rate F1 is set to a fuel amount increase rate F0 (S17). When the engine internal combustion engine is determined to be under an acceleration operation state, the larger one of the first fuel amount increase rate F1 and second fuel amount increase rate F2 is set as the fuel amount increase rate F0 (S15-S17). Fuel injection control is executed on the basis of the set fuel amount increase rate F0. <P>COPYRIGHT: (C)2012,JPO&INPIT |
