Title:

CARRIER FOR EXHAUST GAS PURIFYING CATALYST

Document Type and Number:

Japanese Patent JP2018008244

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a carrier for an exhaust gas purifying catalyst exhibiting high heat proof structure stability even if using a metallic honeycomb base material, and reduced in danger of generating defects such as breakage of the honeycomb base material, and dropout of the honeycomb base material from an outer cylinder even when high load operation.SOLUTION: A carrier 10 for an exhaust gas purifying catalyst includes a metallic honeycomb base material 1, and an outer cylinder 2 where an outer periphery of the honeycomb base material 1 has a region 11 surrounded by the outer cylinder 2, and a region 12 not surrounded by the outer cylinder 2, and connected to the outer cylinder 2 by a region 13 which is at least a part of the region 11 surrounded by the outer cylinder 2, the region 12 not surrounded by the outer cylinder 2 covers not less than 15% and not greater than 85% of a total length of the honeycomb base material 1 from an upstream end part of an exhaust gas flow, and the region 13 connected to the outer cylinder 2 covers not less than 10% and not greater than 85% of a total length of the honeycomb base material 1.SELECTED DRAWING: Figure 1
