摘要: Particulate filters for reducing NOx and particulate matter in diesel exhaust methods forming the same are disclosed. In one embodiment, a filter may include honeycomb body with plurality of channel walls extending from an inlet end to outlet end. At least first set channels plugged proximate at or A zone extend axial direction filter. DeNOx be located downstream zone. The functional catalyst ratio permeability κfz κDz (κfz:κDz) is 2.
