EMISSION CONTROL CATALYST ASSEMBLY FOR ENGINE OF VEHICLE

摘要

PURPOSE: An emission control catalyst assembly for an engine of a vehicle is provided to form the shorter small container, and to fill the shorter small container with more catalyst material without lowering of the capacity by minimizing the pressure deviation with forming the ends through computational hydromechanics. CONSTITUTION: An emission control catalyst assembly(10) for an engine includes a container(12) surrounding a catalyst substrate. The catalyst substrate substantially fills an enlarged diameter section(18) of the container. The catalyst substrate has end faces axially intruding into interiors of tapered sections(20,22) of the container. The small container is formed with the catalyst substrate to fill the small container with more catalyst material.
