PURPOSE:To enable excellent control of an increase in an injection amount over an entire operation range, by a method wherein, during restoration to fuel injection from the stop condition of fuel injection during deceleration, a control method for an increase in fuel during restoration to an acceleration range is different from that during restoration to an idle range. CONSTITUTION:When a deceleration operation state is detected by a deceleration detecting means 16, the output of a signal from an injection control means 20 is blocked by an injection stop means 21 to cut the supply of fuel. In which case, during a given period of time immediately after the operating state of an engine is restored from a deceleration fuel cut range of an acceleration range, based on the outputs of a deceleration restoration detecting means 18 and an acceleration detecting means 17, an increase in an amount of fuel injected from an injection valve 9 is controlled by temporary injection control means 22. Meanwhile, during a given period of time right after restoration from a deceleration fuel cut range to an idle range, an increase in an amount of fuel injected is controlled by a time width widening means 23 which widens the time width of an injection control signal from the injection control means 20. |
