ABSTRACT:
The present invention relates to an emission control system for reducing gases from the exhaust of a combustion engine. In at least one embodiment, the emission control system includes an exhaust passage for transporting the exhaust from the combustion engine, and a particulate filter and selective catalytic reduction (SCR/PF) unit disposed within the passage, with the unit having a plurality of spaced filter walls extending axially along the passage and selective catalytic reduction catalyst variably loaded on the unit to provide a more uniform pressure drop relative to a unit having uniformly loaded catalyst.
