PURPOSE:To carry out an interruption injection control at an optimum timing at accelerating from a low engine speed region to a high engine speed region, by varying a determination time from an accelerating operation start to an interruption injection start according to an engine speed. CONSTITUTION:A fuel quantity is set by a fuel quantity setting means C according to an output signal from an operational condition detecting means B for detecting at least an accelerating condition of an engine A. A driving pulse signal corresponding to the injection quantity set as above is outputted from an output means E to a fuel injection valve D. An acceleration increased fuel quantity is set by a setting means F upon detection of the accelerating condition. A determination time from an accelerating operation start to an interruption injection start is determined by a setting means H according to an output from an engine speed detecting means G. After a time counted by a timer means I becomes over the determination time, an interruption pulse signal corresponding to the acceleration increased fuel quantity is outputted from an output means J and is interrupted between the driving pulse signals. Then, the interruption pulse signal is fed to the fuel injection valve D.
