Exhaust gas purifier
Automotive gas purifiers having a tubular core for conveying hot exhaust gases from an entrant opening to an exit opening in a hollow casing which surrounds the core, a plurality of transversely louvered openings in said tubular core and providing a plurality of small passages in said core means for passage of exhaust gases into and out of the annular space, a transverse wall dividing said annular space into an upstream segment and a downstream segment, a body of small catalyst particles for purifying said hot exhaust gases in said annular space of said upstream segment and surrounding said passages within said upstream segment, wrappings of fiberglass substantially filling the downstream segment of said annular space, said tubular core being a one-piece tube or a two-piece tube in which tubular core is divided into an upstream part extending from the gas entrant end of said casing to one side of said transverse wall and a downstream part extending from the opposite side of said transverse wall to the gas exit end of said casing, said upstream and downstream parts being divided by a part of said transverse wall, which part has a plurality of small passages for passage of part of the exhaust gases through from said upstream part directly into said downstream part, and said transverse wall having a plurality of small apertures therein and through which said exhaust gases can flow from said annular space of said upstream segment to the downstream segment.
