ABSTRACT:
An internal combustion engine has an exhaust gas recirculation system to recirculate a portion of exhaust gases into an induction passage downstream of a throttle valve under the control of a valve device that is actuated by a vacuum in the induction passage and has a carburetor including a manifold vacuum responsive enriching system. The engine also has means detecting conditions where recirculation of exhaust gases is effected and valve means for controlling vacuum applied to a servo in the enriching system to render the enriching system in its operative condition. The enriching system may include a conventional power piston device which increases fuel flow during high power demanded conditions or a conventional air fuel mixture circuit system which supplies air fuel mixture to the induction passage downstream of the throttle valve during periods of deceleration.
