An exhaust gas recirculation system including an intake passage, an exhaust passage joining the intake passage at a junction and in fluid communication with the intake passage, and a closing member having a first position and a second position. When in the first position, the closing member blocks fluid communication between the intake passage and the exhaust passage. When in the second position, the closing member permits fluid communication between the intake passage and the exhaust passage and creates a pressure differential across the junction so that the fluid is either drawn or forced into the intake passage. |
