<p>An emission treatment system and method for simultaneously remediating the nitrogen oxides (NOx), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The emission treatment system includes a catalyzed soot filter comprising a wall flow monolith and a catalyst comprising support particles. The wall flow monolith may be washcoated with a slurry comprising catalytic support particles without applying a passivation layer to the wall flow monolith.</p> |
