ABSTRACT:
The cross-sectional area of a bypass passage around a throttle valve in an intake passage of an internal combustion engine is additionally increased by a predetermined value only when the throttle valve changes from an open position to the fully closed position during a heavy load condition or during a transitional condition from the heavy load condition to a light load condition. Therefore, the flow rate of the intake air at deceleration is not additionally increased during a light load condition, since that would cause the operation of the engine to be stable during deceleration.
