A metal support for exhaust gas cleaning has a metal honeycomb core body fabricated by laying a planar sheet on a corrugated sheet and rolling the laminated sheets into a cylindrical configuration. The corrugated sheet has sinusoidal shaped portions having a wave height which is sufficient to contact the adjacent planar sheet and square wave portions which have a wave height which is insufficient to enable contact with the adjacent sheets. The square wave portions have corners which project out beyond the sinusoidal shaped portions and produce agitation and disturb the flow of gas and to induce an increase in the contact efficiency between the gas and surfaces carrying catalytic material. The planar sheet is not limited to continuously flat sheets and can include flat surfaces formed by zigzag or square wave shaped members. These members can be perforate and or made of a mesh material.

1. Field of the Invention
This invention relates to a metal honeycomb core body having honeycomb structure that is the principal structural element of an exhaust gas cleaning metal carrier which is generally installed at an intermediate point of an exhaust system of a motor vehicle and used as a cleaning means of exhaust gas.
More particularly, this invention relates to a new structure of the above-mentioned metal honeycomb core body for a metal carrier for exhaust gas cleaning comprising a metal honeycomb comprising honeycomb structure for carrying exhaust gas cleaning catalyst and a metal-made casing for containing the metal honeycomb core body.
FIG. 1 is a perspective view of a metal support (MS) fabricated using a metal honeycomb core body (H) (rolling type) in accordance with the first embodiment of the present invention.
FIG. 2 is a front view of the metal support (MS) shown in FIG. 1.
FIG. 3 is a partial cross-sectional view along the axial center of the metal honeycomb core body (H) in accordance with the first embodiment of the present invention.
Technical structure and embodiments of the present invention will be described in detail hereinafter referring to the drawings.
Needless to say, this invention is by no means limited by the attached drawings.
FIG. 1 to FIG. 7 are figures for illustrating a metal honeycomb core body (H) according to the first embodiment of the present invention.
