ABSTRACT:
A forced air control valve for an air injection system in an internal combustion engine is shifted during cold engine operation to divert air flow to the exhaust manifold upstream of a catalytic converter bed to supply air to the exhaust gases for further combustion prior to entry in the catalytic converter. A diaphragm operated main valve is responsive to a vacuum from the intake manifold for diverting air to the exhaust manifold and a temperature activated vacuum switch shuts off the vacuum when the engine warms up. Upon deceleration during cold engine operation the control valve is shifted to divert air away from the exhaust manifold.
