摘要： The present invention provides an exhaust gas purification device for an internal combustion engine, comprising an exhaust passage including a catalyst for conveying exhaust gas discharged from the engine to the outside, and a bend formed by bending a portion of the exhaust passage directly upstream of the catalyst, the bend causing exhaust gas discharged from the engine to collide against a corner portion between an inlet end face of the catalyst and such portion of a wall of the exhaust passage that follows the outside of the bend, thereby increasing pressure at the corner portion, compared with the other portion of the inlet end face, and an additive injection valve fitted to the outside of the bend of the exhaust passage to inject an additive in such manner that the injected additive passes just above the corner portion and falls on the inlet end face of the catalytic converter.
