ABSTRACT:
Air intake side secondary air supply system for an internal combustion engine includes first and second secondary air supply passages leading to an intake manifold in which an open/close valve and an air control valve are respectively provided for a proportional control and an integral control of secondary air. In order to improve a driveability of the engine during a transition period from a feedback control mode to an open loop control mode, pressure control device for controlling a supply of first and second control pressures respectively for opening and closing the air control valve is constructed to rapidly supply the second control pressure when a state of engine operation in which the feedback control mode is to be stopped is detected.
