A heat-insulating resilient supporting and sealing member inserted in a monolithic type catalytic exhaust gas purifier of generally elliptical cross section between an inner wall of a casing and the outer periphery of a monolithic catalyst housed in the casing such that a thicker portion of the supporting and sealing member is disposed at a smallest cross dimension region of the casing, and a thinner portion of the supporting and sealing member is disposed at a largest cross dimension region of the casing, so that the bulk density of the member at the operating temperature of the catalytic purifier is approximately constant around the periphery of the member.

Exhaust gas purifier with resistant circumferential sealing member

A catalytic converter in which at least two catalyst units are arranged within a casing in the direction of exhaust gas flow, with a space between the units transverse to the exhaust gas flow direction. A secondary air supply pipe is inserted into this space in such a manner that a base portion of the inserted pipe is sealingly secured to the casing, while the downstream end of the inserted pipe is supported by a resilient strap or leaf member, one end of which is secured to the downstream end of the inserted pipe and the other end is secured to the casing.
