PURPOSE:To improve accelerating performance of an engine, by performing a plurality of non-synchronous injections in addition to synchronous injections at the instant when an acceleration signal is produced. CONSTITUTION:At the time of accelerating an engine, such an amount of fuel as required by each cylinder at each time instant is supplied smoothly to each cylinder. That is, a plurality of non-synchronous injections of fuel is caused in addition to synchronous injections. Non-synchronous injection may be performed, for instance, once between synchronous pulses 1a and 1b when an acceleration signal is produced just before the suction stroke of a cylinder, #3 and then another injection between synchronous pulses 1b and 1c, as shown by 2a, 2b in the drawing. By thus improving response of the engine, it is enabled to improve the accelerating performance of the same. |
