Adaptive diesel particulate filter regeneration control and method |
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 loading of the DPF based least partially on the soot signal, and a readiness level based on the operating parameter. A soot level trigger is determined based on a time period since a regeneration was completed and the readiness level, and a debounce time period is determined based on the soot loading and the readiness level. The controller is configured to initiate a regeneration event of the DPF when the debounce time period has expired while the soot loading exceeds the soot level trigger.
