Abstract

A fuel injection control apparatus for an internal com­ bustion engine for supplying an additional amount of fuel in addition to a basic amount of fuel when an acceleration condition is detected in accordance with a throttle opening change rate.
The apparatus stops the injection of the additional amount of fuel when a deceleration state is detected in a state where both of the basic and additional amount of fuel are injected.
