PURPOSE:To prevent the generation of a surge, by measuring a duration time, in which a throttle valve is continuouly opened above an idling opening, before the throttle valve is placed to the idling opening and changing a level of a deceleration excess in accordance with the duration time, in a fuel injection device performing the deceleration excess. CONSTITUTION:If a throttle valve placed to an idling opening is detected in a step 70b, a process for determining a deceleration excess is performed. A time, in which an intake system throttle valve is continuously opened to above the idling opening, is read. Whether an idling time is above 0.5sec or not is decided in a step 72b, if the idling time is below 0.5sec, it is not considered as the deceleration. An excess of fuel injection quantity is performed in a step 76. In this way, the generation of a surge due to an excess can be prevented. |
