PURPOSE:To perform fuel injection as much as the required quantity in an accurate manner, by setting the value made up of subtracting the injection quantity calculated at the last time from that calculated this time down to a final injection quantity, while compensating the injection quantity in a direction where the final injection quantities between injections of two times continued accord with each other. CONSTITUTION:In case of a device which sprays fuel to an internal-combustion engine A from a fuel injection device B, there is provided with a device C generating a timing signal synchronously with the specified internal of a crankshaft. And, also there is provided with an operational device D calculating a fuel quantity for a series of injections corresponding to an engine running condition, whereby the fundamental fuel quantity calculated by the said device D when there was the last timing signal is stored in a memory device E. And, the fundamental fuel quantity calculated by the operational device D and a final injection quantity as a difference in the last fundamental injection quantity stored both are calculated by another operational device F, whereby the injection quantity is constituted so as to be compensated in a direction where the actual injection quantities between injections of two times continued accord with each other by a compensating device G.
