A catalytic converter for treating pollutants contained in exhaust gas from an internal combustion engine, includes a chamber having an inlet disposed at a first end of the chamber for introduction of the exhaust gas and an outlet disposed at a second end of the chamber opposite the first end for discharge of the exhaust gas from the chamber after treatment; a front plate provided at the inlet of the chamber and having defined therein a plurality of openings; first, inner, and second, outer, fixed cones positioned within the chamber, disposed in a spaced apart and parallel relationship to one another, and having a plurality of spaced apart holes defined therein, wherein the plurality of holes defined in the first fixed cone are disposed in a staggered relationship to the plurality of holes of the second fixed cone, and wherein the first fixed cone defines with the front plate a first zone within the chamber; a catalyst bed which is disposed in the space defined between the first and second fixed cones, through which the exhaust gas entering the chamber through the inlet flows radially there through, and which contains catalyst in use; a diffuser section provided in the second end of the chamber, through which the outlet is provided, and within which is defined a second zone; a conical member extending from the first fixed cone into the diffuser section for providing a reduced jet effect of the exhaust gas entering the chamber; and a feeding zone for the catalyst defined by closure of a wall surface of the first and second fixed cones adjacent to the inlet.
