Exhaust treatment methods and systems |
摘要 |
A method of evaluating a particulate filter of an exhaust treatment system is provided. The method includes: selectively enabling at least one of data collection and resistance evaluation based on a particulate matter level in the particulate filter; when data collection is enabled, computing a particulate filter resistance based on a linear regression model; and when resistance evaluation is enabled, evaluating an efficiency of the particulate filter based on the particulate filter resistance.
