PURPOSE:To prevent the back-fire of an internal combustion engine as well as to maintain good acceleration ability thereof, by restricting air-fuel mixture form becoming leaner at the acceleration of an engine, through a process of increasing for compensating the interrupt injection quantity in accordance with the volumetric quantity of the deposit which is stuck on the back surface of an intake valve. CONSTITUTION:A quantity of fuel determined by a means B in accordance with the engine driving condition detected by a means A is injected, at a preset interval, from a fuel injection valve D which is driven by an injection pulse signal from a means C. And, after the acceleration state is detected by the means A, a fuel quantity determined finally by a means H is injected interruptingly based upon the fundamental interrupting injection quantity set by a means E and the compensatory interrupting injection quantity from a means G searched by a means F immediately. Following this, when a lapsed time measured by a means I reaches the predetermined time, an air fuel ratio detected by a means J is compared with a reference value by a means K. When the detected value of the air fuel ratio is leaner than the reference value, the compensatory interrupting injection quantity stored in the means G is corrected in increasing compensation by a means L.
