F01N 3/10

US Classification:

60286, 422168

Abstract:

Apparatuses described herein relate to a diesel particulate filter for use in a diesel engine exhaust system. The diesel particulate filter comprises a particulate filter having a plurality of filter flow channels configured to remove diesel exhaust particulates from a diesel exhaust stream. The plurality of filter flow channels are disposed for contact with the diesel exhaust stream and are coated with a three-way catalyst coating. The three-way catalyst coating may be configured to assist in soot oxidation during regeneration events as well as for the reduction of NOfrom the exhaust stream. The three-way catalyst coating may replace, or be used in addition to, a three-way catalyst of a diesel oxidation catalyst.

International Classification:

B01D 53/94

US Classification:

422170

Abstract:

A system for improving NOreduction by incorporating an upstream treatment housing having a dual functionality catalyst that includes a diesel oxidation catalyst and a three-way catalyst, and which is positioned upstream of a main exhaust gas treatment system. The upstream treatment housing is positioned in relative close proximity to an exhaust turbine to prevent or minimize a reduction in exhaust gas temperature as the exhaust gas travels between the outlet of the turbine and the upstream treatment housing. By preventing such a reduction in exhaust gas temperature, the three way catalyst in the upstream treatment housing may operate at exhaust gas temperatures higher than those in main exhaust gas treatment system, which may allow for NOconversion in the upstream treatment housing during certain cold operating or ambient conditions that is not typically attained in the main treatment system during such conditions.
