PURPOSE:To keep responsiveness and exhaust emission at the time of transition so favorably, by installing a discriminating device discriminating a driven state, which makes the degree of smoothing differ, and a smoothing device smoothing an equilibrium quantity or an under-and-over quantity in an engine suction system holding fuel quantity. CONSTITUTION:A variation in a driving state is operated by an operational device 9, and the driving state that makes the degree of smoothing differ according to this variation is discriminated by a discriminating device 10. In response to this discriminated result, an equilibrium quantity MO or an under-and-over quantity DM in an engine suction system holding fuel quantity is smoothed by a smoothing device 11. In consequence, a signal waveform of the MO and the DM varied as receiving the influence of suction pulsation is made even by smoothing operation at time of steady driving, thus any influence on the suction pulsation is eliminated. Thus, drivability and exhaust emission at the time of transition is favorably keepable.
