Abstract (en)
An exhaust gas re-circulation device for an internal combustion engine comprises an intake air channel (10), an intake air control valve (24), an exhaust gas re-circulation valve (20) and an actuator (28). A first motion transmission mechanism is connected between the actuator (28) and the exhaust gas re-circulation valve (20). A second motion transmission mechanism connected between the actuator (28) and the intake air control valve (24). A sense of motion reversing mechanism is included in the first motion transmission mechanism, for reversing the sense of motion of the exhaust gas re-circulation valve (20). The actuator (28) enables, on the one hand, to control exhaust gas re-circulation rates, by simultaneously driving the two valves (20, 24) in opposite senses, and, on the other hand, to obtain a smooth engine shutoff, by simultaneously closing the two valves (20, 24). <IMAGE>
