ABSTRACT:
An auxiliary air amount control system for an internal combustion engine has an auxiliary air passage bypassing a throttle valve arranged within the intake pipe of the engine, and a control valve controlling the amount of auxiliary air supplied to the engine through the auxiliary air passage by varying the opening of the passage. The opening of the control valve is set in response to the opening of the throttle valve, and is decreased progressively from the set value as an initial value when the engine is in a predetermined decelerating condition. The set control valve opening is varied to a larger value as the reduction ratio assumed by a transmission connected to the engine is larger. The minimum value of the throttle valve opening at which the control valve opening can be set to a value larger than zero is varied to a smaller value as the reduction ratio is larger. The rate at which the control valve opening is progressively decreased is varied to a smaller value as the reduction ratio is larger.
