Abstract: A diesel engine exhaust treatment system is provided which includes a diesel oxidation catalyst and a diesel particulate filter, where a first SCR catalyst is positioned at the inlet of the diesel particulate filter, and a second SCR catalyst is coated on the filter. The first and second SCR catalysts each have a low loading, such that a lower backpressure is achieved over the use of a single SCR-coated diesel particulate filter at higher catalyst loadings. The exhaust treatment system also provides effective catalyst efficiency for removal of NOx and other gaseous emissions.

Abstract: A diesel engine exhaust treatment system and method is provided which utilizes a diesel particulate filter positioned in the exhaust gas stream of a vehicle which includes an SCR catalyst, an ammonia oxidation catalyst, and/or a diesel oxidation catalyst. The system is capable of performing multiple functions including converting NOx to N2, converting HC and CO to H2O and CO2, trapping particulates, and minimizing ammonia emissions.
