Honeycomb body and catalyst converter having catalyst carrier configured of the honeycomb

摘要

In a metal catalyst converter (1) configured of the metal catalyst carrier (10) that holds the catalyst into the honeycomb body created by alternately winding flat sheet (2) and corrugated sheet (3), a plurality of slits (4) matrix that extend in the direction perpendicular to the exhaust gas direction are arranged on at least one part of the upstream side of the exhaust gas passage. By that a low heat capacity and high heat transfer area in regard to the downstream side of the exhaust gas passage was formed. The upstream portion of the metal catalyst converter (1) on which slit matrix (4) was formed is configured to be covered by outer casing (8) providing an air insulation layer (S). The upstream side of this outer casing (8) is held by and fixed to the exhaust gas passage.
