Abstract: 1485208 Regulating I C engine exhaust gas recirculation NISSAN MOTOR CO Ltd 11 June 1975 [11 June 1974] 24995/75 Heading F1B An exhaust gas recirculation system for an I.C. engine comprises a recirculation conduit 15 for delivering exhaust gas to the intake manifold 14, a first valve 20 operable to increase the effective open area of conduit 15 in response to increase in vacuum at a port 100 opening into the intake pipe near the throttle valve 13, and a second valve 40 operable to decrease the effective open area of conduit 15 in response to increase in intake manifold vacuum at a port 103. Servos 25, 45 containing spring-loaded diaphragms 27, 47 operate valves 20, 40 and communicate with ports 100, 103' via conduits 102, 104', the latter containing metering orifices 105, 106. Under light load with closed or partially closed throttle valve, valves 20 and 40 are closed respectively by low vacuum at port 100 and high vacuum at port 103', thereby preventing exhaust gas recirculation. As the throttle valve opens for normal running, the vacuum at port 100 rises, opening valve 20, whilst the vacuum in manifold 14 falls, opening valve 40, thereby permitting exhaust gas recirculation. Under full load operation with wide open throttle valve, low vacuum at ports 100 and 103' results in opening of valve 40 and closing of valve 20, effectively preventing exhaust gas recirculation. Abnormal pressure differences between the upstream and downstream ends of valve 40 are eliminated by a conduit 110 containing a metering orifice 111. A conduit 112 containing a checkvalve 113 and by-passing orifices 105, 106 may be included to allow slightly subatmospheric air to enter servo 45, upon sudden acceleration. In another embodiment, Fig. 1 (not shown) port 103' opens directly into the intake manifold and conduits 110, 112 are omitted.
