ABSTRACT:
A fuel injection control apparatus is capable of supplying a proper amount of fuel by improving response when the throttle position is abruptly changed. The fuel injection control apparatus includes an electronic control unit for determining a fuel injection time period for a fuel injection system, based on the engine speed and the throttle position. The electronic control unit is operable to determine a base fuel injection time period based on engine speed and throttle position to start fuel injection, and adjusts the initial fuel injection time period thereafter, based on changes in the engine speed and the throttle position.
