Embodiment Construction

[0049] The best mode for carrying out the present invention is explained below with reference to the drawings. It is assumed that the drawings are viewed from the direction of the reference numerals.

[0050] Fig. 1 is a perspective view of a metal honeycomb catalyst carrier according to the present invention.

[0051] The metal honeycomb catalyst carrier 11 includes a wound honeycomb carrier body 12, a hollow cylindrical member 13 covering the wound honeycomb carrier body 12, and welding portions 14, 15 for fixing the wound honeycomb carrier body 12 to the hollow cylindrical member 13 .

[0052] Fig. 2 is a plan view of a metal honeycomb catalyst carrier according to the present invention. Referring to FIG. 2 and FIG. 1 , the wound honeycomb carrier body 12 has a honeycomb cross section. The wound honeycomb carrier body 12 includes a central cylindrical portion 17 formed in a central region 16, a honeycomb portion 18 communicating with the central cylindrical portion 17 ra...

Abstract

The present invention relates to a metal honeycomb catalyst carrier (11), wherein a waveform-like part (24) is formed on one side (33) of a metal thin strip (23) in the longitudinal direction (in the direction of an arrow a2). A plurality of these strips (23)... are alternately stacked on each other in such a manner that the other side (34) flat plate part (35) of the other strip (23) is placed on the waveform-like part (24) on the one side and wound up starting at the longitudinal center part (25) thereof to form a rolled honeycomb body (12) of honeycomb shape in cross section, and the rolled honeycomb body is fitted to a hollow cylindrical member (13). Where the diameter of the center cylindrical part (17) of the rolled honeycomb body (12) fitted to the hollow cylindrical member (13) is D, the longitudinal length Lm of the center flat part (25) of the rolled honeycomb body is set to at least 4.14D.

Description

technical field [0001] The present invention relates to a cylindrical metal honeycomb catalyst carrier for carrying a catalyst for purifying exhaust gas discharged from an internal combustion engine. Background technique [0002] There is known a metal honeycomb catalyst carrier in which each member is formed with a corrugated region on one side of a metal belt plate except for its central region and other portions remaining flat, and these members are stacked alternately so that the A corrugated region of a member is in mutual contact with a plate portion of another member, and these members are wound around their centers to form a cylindrical honeycomb body covered with an outer hollow cylindrical member (for example, see Patent Document 1). [0003] Patent Document 1: Japanese Patent Unexamined Publication JP-A-7-116758 (4-5 pages, Fig. 1 and Fig. 3 ) [0004] Patent Document 1 will be explained below with reference to the drawings. [0005] 6A to 6C are diagrams for ex...
