Abstract:
A particulate filter assembly, an exhaust gas treatment system having a particulate filter assembly, and a control method for flow controlled zoned regeneration of the particulate filter assembly are provided. The particulate filter assembly is configured to receive an exhaust gas stream from an internal combustion engine and includes an inlet end configured to receive the exhaust gas stream, a filter configured to remove particulates from the exhaust gas stream, a heating device positioned upstream from the filter having a plurality of zones, each zone of the plurality of zones independently operable to heat a corresponding region of the filter and an exhaust flow valve positioned downstream from the filter configured to selectively restrict flow of the exhaust gas stream through the filter.
