Abstract
An air intake side secondary air supply system for an internal combustion engine equipped with an automatic choke valve and a fast idle system is provided with a detection means for detecting an operating condition of the engine in which the fast idle system is operated to open the throttle valve. The supply of the secondary air for the feedback control is stopped when a detection signal is produced by the detection means so that the feedback control of the air-fuel ratio is suspended when the throttle valve is opened by means of the fast idle system while the choke valve may be substantially closed. Thus, a hunting of the engine speed which might have occured after the start of the feedback control is prevented.
