Abstract

Official abstract text for this publication.

A catalyst unit may include a carrier that channels may be formed from a front surface thereof to a rear surface thereof, and plugs that closes the channels that may be formed along an edge portion of the front surface except a central portion of the front surface, wherein a coating layer may be not formed in the channels that the plugs may be disposed and a coating layer may be formed along the remaining opened channels.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing a catalyst unit, comprising: extruding a carrier wherein the carrier includes open channels formed in the carrier from a front surface to a rear surface of the carrier; plugging a subset of the open channels formed along an outer edge portion of the front surface of the carrier by plugs, forming closed channels; and coating catalyst along remaining open channels not plugged by the plugs, wherein the front surface of the carrier is dipped into a catalyst solution, which is wash coat, and the catalyst solution is configured to be pulled from the rear surface of the carrier through a front surface of the remaining open channels by a suction force applied to the rear surface of the carrier such that the catalyst solution is coated along an interior surface of the remaining open channels.
