Abstract
PURPOSE: To improve the drivability by effecting the exhaust gas recirculation at a higher recirculation rate during intermediate and high load running cinditions than that during a light load running condition.
CONSTITUTION: An exhaust gas recirculation device is composed: a recirculation control valve 1 which is mounted in a recirculation exhaust gas passage 13 such that its opening is controlled by a diaphragm 9; first and second ports 13 and 28 which are located upstream of a throttle valve 12 for taking out the intake vacuum established at the open position in accordance with the opening of the valve 12; first and second conduits 14 and 29 through which the respective ports 13 and 28 have communication with a diaphragm chamber 8; and a vacuum regulating valve 15 which is mounted midway of the first conduit 14 for regulating the intake vacuum in the first conduit 14 in accordance with the exhaust pressure. During the intermediate and high load running operations having the second port 28 opened, the intake vacuum is introduced directly into the diaphragm chamber 8 to increase the opening of the control valve 1 so that the exhaust gas recirculation may be accomplished at a higher recirculation rate than that during the light load running condition.
