Abstract (en)
First wings (111c) projecting in a first direction perpendicular to the flow direction of EGR gas and second wings (111c) projecting in a second direction perpendicular to the flow direction of the EGR gas and different from the first direction are provided on an inner fin (111). From a macroscopic viewpoint, the EGR gas collides with the wings (111c) and passes through the exhaust gas passage (110a) while meandering in the direction (D1) perpendicular to a longitudinal direction (D0) of the exhaust gas passage. Accordingly, the tendency that the EGR gas passes only along the portion that has no projection (111c) and that has a small flow resistance does not occur. Therefore, from the viewpoint of the entirety of the exhaust gas passage (110a), it can be considered that the EGR gas substantially uniformly collides with the projections (111c) to thereby enhance the heat transmissibility and prevent the deposition of particulate matters.
