Exhaust gas recirculation system
Patent
·
OSTI ID:5532658
An exhaust gas recirculation system comprises a valve assembly for controlling the recirculation of exhaust gases in such a manner as to maintain a difference between a first and second pressure at a predetermined value. The first pressure is a pressure in a zone in an air induction passage between a throttle valve therein and a flow restrictor disposed therein downstream of the throttle valve, while the second pressure is a pressure in a zone in an exhaust gas recirculation passage between an exhaust gas recirculation flow control valve member and a second flow restrictor disposed therein downstream of the valve member.
