Abstract: PURPOSE:To eliminate dispersion of a fuel supply control at the time of acceleration or the like by suspending only the thinning of the first fuel injection when it must be thinned, in the case of an operation parameter with its changing amount per unit time exceeding a predetermined value. CONSTITUTION:In a control unit 8, in accordance with a load condition of an engine 10 with signal data from various sensors serving as an operation parameter and in an operational region with a load exceeding a predetermined value, an injection pulse signal is generated in each reference signal from a reference angle sensor 6 similarly to an ignition signal to an ignition coil 9. While in an operational region with the load not more than the predetermined value, the reference signal is thinned by a predetermined quantity, for instance, an injection pulse signal is thinned by one time per two times. Now when the operation parameter is rapidly changed, immediately thereafter fuel is injected surely one time in the timing similar to when the thinning is not performed. Thus suppressing generation of dispersion and delay in the follow-up characteristic of fuel supply, fixed control responsiveness can be always held.
