ABSTRACT:
The so called air intake side secondary air supply system for an internal combustion engine includes first and second secondary air supply passages leading to an intake air passage on a downstream side of a throttle valve. The system is provided with a delay device in the second secondary air supply passage on an upstream side of an open/close valve disposed in the second secondary air supply passage, a pressure supply passage which provides communication between a pressure chamber of an air control valve disposed in the first secondary air supply passage and a part of the second secondary air supply passage between the delay device and the open/close valve, a second air supply delay means disposed in said pressure supply passage and a pressure control means for supplying a pressure for reducing the opening degree of the air control valve into said pressure supply passage during a predetermined operating condition of the engine.
