ABSTRACT:
Apparatus for controlling introduction of gas into a passage of an internal combustion engine employs a first control valve in a gas introduction passageway, a second control valve in an air conduit connecting the intake passage to atmosphere, and a regulating valve responsive to vacuum intensity in the intake passage. The regulating valve actuates vacuum responsive actuators for the control valves. This system is used for recirculating exhaust gases into the intake passage, for introducing supplementary atmospheric air into the intake passage to modifying the air-fuel ratio in accordance with atmospheric pressure reduction at high altitudes, and for controlling the introduction of atmospheric air into the exhaust passage upstream from a catalytic converter or reactor.
