ABSTRACT:
An electronic fuel injection control apparatus for an internal combustion engine mounted on an automotive vehicle. In a vehicle system where the amount of fuel injected to the engine is electronically calculated from the rotation speed and the amount of sucked air at every rotation of the engine, the operating condition of the engine is monitored and discriminated as to whether the monitored operating condition is in a predetermined operating range where the surge of the automotive vehicle is apt to occur due to the resonance between the change in the output torque of the engine and the vehicle mechanical structure. The amount of fuel is calculated from the currently measured value of the amount of sucked air and the currently measured value of the rotation speed in response to the discrimination result indicating little potential for the occurrence of surge, whereas it is calculated from the currently measured value of the amount of sucked air and a corrected value of the rotation speed in response to the discrimination result indicating high potential for the occurrence of surge. The corrected value of the rotation speed is calculated from the currently measured value of the rotation speed so that the corrected value changes less from the precedingly measured value of the rotation speed than the currently measured value of the rotation speed.
