ABSTRACT:
A secondary intake gas control system for an internal combustion engine having a secondary intake gas supply means for supplying air or a lean mixture to a combustion chamber, comprising an air control valve means provided in a secondary intake passage means of the secondary intake gas supply means to control a supply of the air. The air control valve means comprises a valve member and actuating means therefor. The actuating means is operated by means for sensing a temperature of the engine and means for sensing an opening degree of a throttle valve to open the valve member to communicate the secondary intake passage means with atmosphere when the opening degree of the throttle valve is above predetermined value at a predetermined temperature range of the engine during warming-up thereof.
