Abstract

PURPOSE: To perform the recirculation control corresponding to the running condition of an internal combustion engine by providing a regulator valve and air valve for adjusting negative pressure amount in an exhaust gas recirculation control for the engine.
CONSTITUTION: Intake and exhaust paths Mi, Me of an engine E are in communication with each other through an exhaust recirculation path 5 having a recirculation amount controlling valve 6 to return a portion of the exhaust gas to the intake path. Negative intake pressure is introduced into a negative pressure chamber 9 of the controlling valve 6 near a throttle valve 3 through an electromagnetic valve 11 for stopping the recirculation if not needed. Also, to the negative pressure chamber 9 communicates to a regulator valve V1 for changing over and introducing negative pressure in a Venturi-pipe 1a and the atmosphere by change-over of an electro magnetic valve 41 to vary the negative pressure amount transmitted to the chamber 9 depending on the running condition of the engine. Further, to a negative pressure chamber 22 of the regulator valve V1 communicates an air valve V2 controlled by negative pressure transmitted to the negative pressure chamber 9 of the controlling valve 6 to transmit the negative pressure amount in the intake path Mi depending on said negative pressure amount for correcting the opening of the regulator valve V1.
