ABSTRACT:
The so called air intake side secondary air supply system for an internal combustion engine, having first and second secondary air supply passages leading to an intake air passage on downstream side of a throttle valve is, provided with a delay device in the second secondary air supply passage on 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, and a pressure control means for supplying a pressure capable of reducing an opening degree of the air control valve into a part of the second secondary air supply passage between the open/close valve and the delay device in response to a predetermined operating condition of the engine. Thus, a range of the air-fuel ratio control is determined according to the operating condition of the engine.
