摘要： An after-treatment device that includes a diesel particulate filter (DPF) requiring periodic regeneration includes a sensor providing a signal indicative of a soot accumulation and at least one device providing an operating parameter indicative of a work mode of the machine. A controller determines a soot level and a readiness level based on the work mode of the machine, and further classifies the soot level relative to a desired range for initiating a regeneration event and initiates the regeneration event when the soot level falls within the desired range.

摘要： An exhaust system for use with a combustion engine is disclosed. The exhaust system may have an exhaust passage, a particulate filter located within the exhaust passage, and a heating device located to selectively heat matter collected within the particulate filter. The exhaust system may also have a controller configured to determine an amount of matter collected within the particulate filter exceeding a threshold amount, and to activate the heating device in a first operating mode to regenerate the particulate filter based on the amount of collected matter. The controller may be further configured to detect a temperature constraining condition of the combustion engine, to determine an amount of oxygen within the flow of exhaust during the temperature constraining condition, and to activate the heating device in a second operating mode to constrain a regeneration temperature of the particulate filter based on the amount of oxygen within the flow of exhaust.
