Exhaust gas purifier system for internal combustion engine
A catalytic converter is mounted within an exhaust gas passage formed by a pair of tubular members each having an outwardly extending flange at their one end and connected together in tandem and in a concentric manner by means of mounting means which cooperate with the flanges. The catalytic converter includes a cylindrical, metallic shell having a pair of flanges at its opposite ends which extend radially inward and which define a gas inlet and a gas outlet, a catalyst carrier formed by a monolithic, porous ceramic body having a coating of catalyst, and elastic support means for supporting the catalyst carrier within the shell. The shell is provided with an annular rib having a pair of side surfaces which project outwardly from its cylindrical surface, the annular rib defining a pair of cylindrical portions of the shell which are contiguous with the respective side surfaces. The catalytic converter is disposed within the pair of tubular members by locating each of the cylindrical portions within the associated tubular member. By connecting the pair of tubular members together by the mounting means, the respective side surfaces of the annular rib engage the associated flanges on the tubular members, thereby supporting the catalytic converter within the gas passage.
