ABSTRACT:
An exhaust-gas purifier comprising a monolithic catalyst which is disposed in an exhaust passage of an engine proper provided with a plurality of cylinders, and which has a plurality of paths running in the direction of the exhaust-gas stream, wherein the exhaust passage is divided into a plurality of passageways opening close to the upstream end of the monolithic catalyst, the passageways being independent from each other or combined with proper others so as to form compound passageways. The part of the independent exhaust passageways corresponding to each cylinder or compound passageways is extended to the downstream end of the monolithic catalyst, substantially separated from each other, thus lowering the interference of each cylinder due to fluctuation of the exhaust pressure exerting adverse effects on each other.
