METHOD FOR CONTROLLING AN EGR CIRCUIT IN A MOTOR VEHICLE ENGINE |
摘要 |
The invention relates to a method for controlling an exhaust gas recirculation circuit for an internal combustion engine of a motor vehicle. The engine is linked to an air intake circuit and to a gas exhaust circuit linked to the air intake circuit by the recirculation circuit. A first valve controls the flow of air upstream from the recirculation circuit, and a second valve controls the flow of exhaust gases that are recirculated within the recirculation circuit. The method comprises the following steps: a) the first valve is closed, and the second valve is gradually opened; b) if the second valve is opened at an angle greater than a value between 25° and 35°, the first valve is gradually opened concomitantly to the opening of the second valve. As a result of the invention, the EGR rate is easily controllable. |
