Abstract: The metal carrier for the exhaust gas purifying catalyst has durability that can endure the high-temperature and high-speed exhaust gas flow and that has anti-thermal-fatigue characteristics for withstanding rapid heating and cooling, and which excels in purifying performances. A metal carrier for an exhaust gas purifying catalyst is provided with a metal honeycomb member having a flat metal foil and a corrugate-processed metal foil piled and wound around in spiral form, and a metal outer tube surrounding this metal honeycomb member. A free-flat-foil is provided at the beginning of winding of the metal foil. And a tubular hollow portion of the honeycomb member in the radial or chord direction is processed either, or by pushing and pressurizing along the innermost circumference portion of the honeycomb member. When the outer diameter of the honeycomb member is ϕA, and the inner diameter thereof is ϕB, it is made to be ϕB ≤ 10/100 x ϕA.

Abstract: Improvement in the engine durability and in the solid phase diffusion connectability of the contact part of a metal flat foil and a metal corrugated film from which a catalyst converter metal honey comb applied to the exhaust gas cleaning is made, characterized in that at least one of the foils has a thickness less than 40 νm and an A1 content after connection is not less than 3 %, and that the surface states in the width directions of both the metal films are formed in a required surface roughnesses or surface patterns, and that the width of the connection part of both the metal foils is not less than 5 times of the thickness of the metal foil. For effective practice of the above improvement, both the surface roughness and the regulation of thickness or either of them have to be selected. In order to improve the engine durability further, a non-connection part is provided in the honey comb element as described above and/or a shell is provided around the outside circumference of the honey comb element.
