FIELD: transport engineering; vehicle internal combustion engines.
SUBSTANCE: invention relates to engine exhaust systems. Proposed carrier of catalyst converter has honeycomb member made of metal sheets. Said honeycomb member is axially extended, and metal sheets, at least partially are either structurized or profiled to form passage channels for exhaust gases. Carrier is provided also with tubular casing with edge and axial extent. Axial extent of tubular casing is less than axial extent of honeycomb member, and tubular casing, at least on one separate axial section is nondetachably connected with honeycomb member. Carrier is provided with bushing whose axial length is less than axial extent of honeycomb member, said bushing is located on outer part of honeycomb member near its end face and it has inner side surface which is nondetachably connected from side of said end face with radially external end sections of metal sheets of honeycomb member. Said honeycomb member projects in axial direction beyond the edge of tubular casing, and said projecting part of honeycomb member is enclosed in bushing. Description of design of converter with such carrier is provided.
EFFECT: prevention of stresses between honeycomb member and tubular casing even at high thermal load on carrier.
