PURPOSE:To suitably control air-fuel ratio at the acceleration time and improve the acceleration performance by when the acceleration state of an internal combustion engine is detected, supplying fuel of quantity set for acceleration mode for internal combustion engine after the sequential controlled regular fuel injection is completed. CONSTITUTION:A sequential control means B independently drives fuel injection valves A (A1 to An) assigned to each of a plurality of cylinders, at the individually set fuel injection timings, whereby performing regular fuel injection at the points coinciding to the respective intake strokes of those cylinders. In such case, a means C detects the internal combustion engine for its acceleration mode and based on the detected acceleration mode and a means D sets the quantity of fuel injected for acceleration mode. Furthermore, a means E detects whether the regular injection is completed at a fuel injection valve A just prior to or detecting an acceleration operation, or not. And if the regular fuel injection has been completed, a means F generates an injection command signal of indicating injection of fuel set for acceleration mode to at least the fuel injection valve A whose cylinder is determined as one in which injection is completed.
