Abstract

Abstract An "in-line" exhaust processor includes a housing (12) having an inlet (20) for introducing a combustion product (21) from an engine and an outlet (24) for exhausting filtered or otherwise treated combustion product from the housing. A first substrate (26) is situated in a forward or upstream position within the housing (12) to filter combustion product (21a) introduced into the housing through the inlet (20). A second substrate (28) is situated in an adjacent rearward or downstream position within the housing (12) to filter combustion product (21) from at least two sources in the manner explained below. Each substrate (26, 28) includes a cellular structure having opposite inlet and outlet ends and a longitudinal axis. The housing (12) includes a first clam shell portion (16) and a complementary second clam shell portion (14) joined to the first clam shell portion to surround and hold the substrate pair (26, 28) in series. The exhaust processor further includes a bypass channel (56) for diverting a selected portion of the combustion product introduced into the housing through the housing inlet (20) to the second substrate (28).
