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 NOand other gaseous emissions.
