Exhaust gas recirculation regulating system

Patent ·
OSTI ID:6540032
A system 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. The regulating valve in combination with a restricted orifice for the actuator of the second control valve act to rapidly stop exhaust gas recirculation when the operator decelerates the engine.
