Abstract
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.
