Abstract
An engine intake air quantity control apparatus is provided with a throttle valve, a supercharger, a variable intake valve operating device and an intake air control device. The throttle valve varies an intake air flow passage area of an intake passage. The supercharger supercharges intake air. The variable intake valve operating device changes an intake valve timing of an intake valve in accordance with an engine operating state. The intake air control device increases an opening degree of the throttle valve in accordance with a detected increase of an accelerator pedal depression amount, and increases an intake air quantity by starting to supercharge the intake air with the supercharger upon a prescribed throttle valve opening degree having been reached. The intake air control device changes the prescribed throttle valve opening degree in accordance with the intake valve timing of the intake valve.
