ABSTRACT:
A catalytic converter for treating exhaust gases includes a carrier and a casing. The carrier has an axis with respect to its contour and is of honeycomb structure. The carrier is made of metal and has catalyst on its surfaces. The casing houses the carrier. The casing is made of metal having a coefficient of thermal expansion relatively close to that of the metal constituting the carrier. The carrier has a tapered outer-surface which is oblique with respect to the axis of the carrier. The casing has a tapered inner-surface which matches the tapered surface of the carrier. The tapered surfaces of the carrier and the casing are substantially in contact with each other so that the casing may axially secure the carrier.
