Abstract
A secondary intake air supply system for internal combustion engines having two vacuum operated air control valves in parallel in a single secondary air supply line to the intake manifold. One of the air control valves is controlled by a vacuum control valve to open and close gradually to avoid abrupt changes in the air fuel mixture to the engine, upon changes in vehicle operation. Electromagnetic valves operated by a control circuit responsive to both an exhaust gas sensor and a throttle position also control the secondary air supplied through the two air control valves.
