<p>Disclosed is an exhaust purification system (2) for an internal combustion engine (1), which comprises: a reduction catalyst (6) that is arranged in an exhaust pipe (exhaust passage) (3) of the internal combustion engine (1); and a reducing agent spraying device (4) for spraying a reducing agent within the exhaust pipe (3) in the upstream of the reduction catalyst (6). A dispersing member (member for promoting evaporation of the reducing agent) (5) is arranged at a position, which is in the upstream of the reduction catalyst (6) within the exhaust pipe (3), and to which the reducing agent is sprayed from the reducing agent spraying device (4). The dispersing member (5) is formed of a porous member and affixed within the exhaust pipe (3) such that the dispersing member (5) is parallel to the flowing direction of the exhaust gas.</p> |
