摘要： An exhaust system may include a canister that is disposed downstream from an engine. A particulate filter (PF) is disposed within the canister and filters particulates within an exhaust from the engine. A reducing catalyst is disposed within the canister, is on the PF, and promotes reaction of a liquid reductant in the exhaust after reception by the PF. A heating element is disposed within the canister and heats particulate matter in the PF.

摘要： A control system comprises an exhaust treatment system, an electric heating module, and an exhaust heating module. The exhaust treatment system comprises a particulate matter (PM) filter and an electric heater. The PM filter includes M zones that receive exhaust gas of an engine and filter PM from the exhaust gas. The electric heater heats exhaust gas input to N of the M zones, wherein M is an integer greater than one and N is an integer less than M. The electric heating module activates the electric heater to heat exhaust gas input to the N zones to regenerate the N zones. The exhaust heating module heats exhaust gas input to the M zones by controlling an air-fuel ratio of the exhaust gas after the N zones regenerate.

摘要： A system comprises a particulate matter (PM) filter that comprises an upstream end for receiving exhaust gas and a downstream end. A zoned heater is arranged spaced from the upstream end and comprises N zones, where N is an integer greater than one, wherein each of the N zones comprises M sub-zones, where M is an integer greater than one. A control module selectively activates at least a selected one of the N zones to initiate regeneration in downstream portions of the PM filter from the one of the N zones and deactivates non-selected ones of the N zones.

摘要： A system includes a particulate matter (PM) filter with multiple zones, an electric heater and a control module. The electrical heater includes heater segments, which each correspond with a respective one of the zones. The electrical heater is arranged upstream from and is proximate with the PM filter. The control module selectively applies a first energy level to a first one of the zones via a first one of the heater segments to initiate regeneration in the first zone. The control module also selectively applies a second energy level that is less than the first energy level to a second one of the zones via a second one of the heater segments to initiate regeneration in the second zone.
