PURPOSE:To improve the response performance in acceleration by controlling the apparatus so that asynchronous fuel injection in accordance with the variation of increase of the intake air amount can be carried-out several times when said variation of increase is over a prescribed value. CONSTITUTION:During engine operation, an electronic control circuit 30 calculates fuel injection amount according to each output of an air flow meter 22, revolution angle sensor 28, and other operation state detection sensor, and in case of ordinary traveling, synchronous fuel injection is carried-out for at least two cylinders in synchronization with the engine revolution. Further, asynchronous injection in the amount corresponding to the variation of increase of the intake air amount is carried-out for at least two cylinders in acceleration. In this case, the speed of increase of the amount of intake air is detected, and it is judged that the detected value is over a prescribed value or not, and in case of YES, asynchronous injection in accordance with the speed of increase of the intake air amount is carried-out several times. Thus, the response performance in acceleration is improved, and fuel consumption is improved, and the amount of uncombusted waste can be reduced. |
