US Patent:

50482874, Sep 17, 1991

Filed:

Jun 19, 1990

Appl. No.:

7/541083

Inventors:

Michael G. Howe - Columbus IN
James C. Arthur - Columbus IN
Robert T. Usleman - Columbus IN

Assignee:

Arvin Industries, Inc. - Columbus IN

International Classification:

F01N 302

US Classification:

60288

Abstract:

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.

Assignee:

Arvin Industries, Inc. - Columbus IN

International Classification:

F01N 302

US Classification:

60288

Abstract:

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.

Abstract:

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.
