DIESEL PARTICULATE FILTER REGENERATION CONTROL AND METHOD

摘要

An after-treatment device (202) that includes a diesel particulate filter (DPF) (206) requiring periodic regeneration includes a sensor (238) providing a signal (306) indicative of a soot accumulation and at least one device (240) providing an operating parameter (242) indicative of a work mode of the machine (100). A controller (222) determines a soot level (310) and a readiness level (312) based on the work mode of the machine (100), and further classifies the soot level (310) relative to a desired range for initiating a regeneration event and initiates the regeneration event when the soot level (310) falls within the desired range.
