More Information
Summary:An EGR passage 6 is connected with an intake passage (a bypass passage bypassing a supercharger) 25 of an engine. The EGR passage includes, in a position close to a connection port 69 to the intake passage 25, an expanding portion 95 in which a passage cross-sectional area expands and which lowers a flow speed of EGR gas so as to reduce an uneven flow, in the connection port 69, of the EGR gas flowing into the intake passage 25.
