PURPOSE:To keep off any drop in output torque of an engine, by checking the performance of fuel increment compensation when a fundamental injection quantity of fuel is more than the specified value even in the case where a suction quantity detection value has varied in a suction reducing direction at more than the specified variation rate. CONSTITUTION:There is provided with a fundamental injection quantity setting device M5 which sets a section quantity Q to be detected by a suction quantity detecting device M14 installed at the upstream side of a throttle valve M3 inside a suction pipe M2 of an internal-combusion engine M1 and a fundamental injection quantity Tp according to engine load Q/N to be found out of an engine speed N. In addition, when the suction quantity Q has varied in a suction quantity reducing direction at more than the specified variation rate, there is provided with an injection quantity increment compensating device M6 which compensates the fundamental injection quantity Tp for increment. And, at the above-mentioned, additionally there is provided with a comparatively judging device M7 which judges whether the fundamental injection quantity Tp is more than the specified value or not, and when the Tp is more than the specified value, increment compensation for the injection quantity by the compensating device M6 is controlled so as not to be performed.
