Abstract:
To provide a recirculation mechanism of exhaust recirculation gas capable of preventing condensed water.SOLUTION: The mechanism comprises: a suction passage 4 for feeding intake air to an engine 1; an exhaust passage 6 for feeding exhaust air from the engine 1; an exhaust recirculation passage 20 for returning one part of exhaust air from the exhaust passage 6 as recirculation gas to the suction passage 4; and a block wall 24 formed in an extension direction of the suction passage 4 and blocking a downstream side of the suction passage 4 near a connection part of the suction passage 4 and the exhaust recirculation passage 20 and than the connection part into a first passage 25 for flowing only intake air and a second passage 26 for flowing mixed gas of suction air and recirculation gas. A passage cross section area of the exhaust recirculation passage 20 at the connection part is larger than the passage cross section area of the second passage 26 at the connection part.SELECTED DRAWING: Figure 2
