METHOD OF MONITORING SOOT MASS IN A PARTICULATE FILTER AND MONITORING SYSTEM FOR SAME |
摘要 |
A method of monitoring soot mass in a particulate filter of an exhaust system includes predicting soot mass in the particulate filter based at least partially on a pressure differential between exhaust flowing into the filter and exhaust flowing out of the filter. The predicted soot mass is then revised based at least partially on measured operating parameters indicative of mass flow rate of nitrogen oxides in exhaust flow of the exhaust system and temperature of the particulate filter. |
