摘要： A regeneration system includes a particulate matter (PM) filter with an upstream end for receiving exhaust gas and a downstream end. A control module determines a current soot loading level of the PM filter and compares the current soot loading level to a predetermined soot loading level. The control module permits regeneration of the PM filter when the current soot loading level is less than the predetermined soot loading level.

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.

摘要： An exhaust treatment system comprises a particulate matter filter, a first heater element, and a second heater element. The particulate matter (PM) filter filters PM from exhaust gas and includes N zones. Each of the N zones includes an inlet area that receives a portion of the exhaust gas. N is an integer greater than one. The first heater element includes a contact area that heats exhaust gas input to an inlet area of a first one of the N zones. The second heater element includes a second contact area that heats exhaust gas input to an inlet area of a second one of the N zones. A ratio of the contact area of the first heater element to the inlet area of the first zone is greater than a ratio of the contact area of the second heater element to the inlet area of the second zone.

摘要： A control system includes a heater control module and a particulate matter (PM) load module. The heater control module selectively activates an electric heater to initiate regeneration in a zone of a particulate filter and deactivates the electric heater after the regeneration is initiated. The regeneration continues along a length of the particulate filter after the electric heater is deactivated. The PM load module determines a PM load based on an outlet temperature of the particulate filter after the regeneration is initiated.

摘要： A system comprises an electrical heater and a particulate matter (PM) filter that is arranged one of adjacent to and in contact with the electrical heater. A control module selectively increases an exhaust gas temperature of an engine to a first temperature and that initiates regeneration of the PM filter using the electrical heater while the exhaust gas temperature is above the first temperature. The first temperature is greater than a maximum exhaust gas temperature at the PM filter during non-regeneration operation and is less than an oxidation temperature of the PM.

摘要： A method for controlling an engine includes receiving a request to regenerate a particulate matter filter and regulating, in response to the request, operation of the engine and an electric heater that heats an inlet surface of the filter such that for a first period, the heater maintains the inlet surface within a first temperature range above a regeneration temperature of the filter and combustion of a first mass of accumulated PM within the filter is initiated, for a second period following the first period, exhaust cools the inlet surface to within a second temperature range below the regeneration temperature and combustion of the first mass is inhibited, and for a third period following the second period, the inlet surface is maintained within a third temperature range above the regeneration temperature and a second mass of the accumulated PM is combusted. A related control system is also provided.
