Abstract
A fuel injection control device for an internal combustion engine in which a fundamental fuel injection amount is set according to suction air amount per one revolution of the engine Q/N. The fuel injection control device includes a transitional operation start timing detector for detecting an acceleration start timing or a deceleration start timing, an engine rotational number measurer for measuring a predetermined number of rotations of the engine from the acceleration start timing or the deceleration start timing, a throttle valve angle detector for detecting that a throttle valve angle is out of a set range, and apparatus for setting an upper limit value and/or a lower limit value of Q/N when the throttle valve angle detector generates a signal showing that the throttle valve angle is out of the set range until the engine rotational number measurer measures the predetermined number of rotations of the engine.
