摘要： An exhaust processor is provided for filtering particulate matter from a combustion product. The exhaust processor includes a partition situated inside a housing to form a filtering region and a bypass region in an upstream portion of the housing. A substrate is mounted in the filtering region for solid particle filtration. A muffler is situated in a downstream portion of the housing spaced apart from the partition so that the entire spacial volume of the muffler can be utilized by combustion product passing through either the filtering region or the bypass region.

摘要： An exhaust processor is provided for filtering particulate matter from a combustion product. The exhaust processor includes a housing providing a main passageway having a substrate mounted therein for solid particle filtration. The housing also provides an auxiliary passageway containing a muffler for attenuating noise of combustion product. Combustion product is diverted through the auxiliary passageway after the substrate collects a predetermined amount of solid particles from combustion product to permit regeneration of the substrate by a burner.

摘要： An exhaust processor is provided for filtering particulate matter from a combustion product. The exhaust processor includes a partition situated inside a housing to form a first flow passage and a second flow passage in an upstream portion of the housing. A main substrate is mounted in the first flow passage for solid particle filtration. An auxiliary substrate is situated in the second flow passage to filter combustion product passing through the second flow passage during regeneration of the main substrate. A muffler is situated in a downstream portion of the housing and is arranged so that the entire spacial volume of the muffler can be utilized by combustion product passing through either the first or second flow passages.

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

摘要： An exhaust processor assembly includes an exhaust pipe and a substrate for treating emissions contained in combustion product emitted from an engine exhaust. The assembly also includes a second pipe for providing a passageway receiving combustion product and the substrate means is positioned in the passageway to treat emissions passed therethrough. The assembly further includes an apparatus for positioning the second pipe in the interior region of the exhaust pipe so that thermal transfer between the substrate and the second pipe is minimized in order to maximize retention of thermal energy by the substrate resulting from the combustion product traveling through the passageway.
