PURPOSE:To improve the transition response performance on acceleration by calculating the corrected injection timing from the taking-in timing of the output signal of a throttle-valve opening-degree sensor and the taking-in timing of the fuel injection control signal and allowing each cylinder to perform transition correction according to the newest information. CONSTITUTION:A fuel injection valve 32 is opening/closing-controlled on the basis of the fuel injection amount obtained according to the data of an engine revolution-number sensor 10, air flow meter 12, etc. When the amount of variation of the opening degree of a throttle valve which is obtained by a throttle- valve opening-degree sensor 18 is over a prescribed value, it is judged as acceleration, and when the time point of transition from stationary state to acceleration state accords with the synchronous injection timing, the concerned cylinder is put into main increment. When the transition to acceleration state is performed after the completion of synchronous injection after synchronous injection timing, said cylinder is allowed to execute asynchronous injection. When acceleration state continues after the completion of the above-described acceleration increment process, the transition correction by main increment is performed by other cylinder. |
