ABSTRACT:
Addition air is admitted into a fuel passage of a carburetor through an open electromagnetic valve which is electronically controlled between the open and closed position in accordance with an oxygen sensor signal indicating the oxygen concentration in the engine exhaust gases. The amount of the additional air being supplied to the fuel passage is reduced at the rate proportional to the vacuum created by operation of the engine in a venturi section, choke section and/or intake manifold.
