| titleOfInvention | Method for monitoring soot mass in a particulate filter |
| abstract | A method of monitoring soot mass in a particulate filter (14) of an exhaust system (12), comprising: Predicting a soot mass (46) in the particulate filter (14) based at least in part on a pressure difference (42) between exhaust (20) flowing into the filter (14) and exhaust (20) flowing out of the filter (14); marked by Checking the predicted soot mass (46) based at least in part on measured operating parameters indicating a mass flow rate (32) of nitrogen oxides in the exhaust gas flow (20) of the exhaust system (12) and a temperature (38) of the particulate filter (14), the checking comprising: Estimating a deviation between the predicted soot mass (46) and the actual soot mass in the filter (14) by applying the measured operating parameters (32, 38) and the predicted soot mass (46) to a stored database (62, 66) of deviations (48 ) between predicted soot mass (46) and actual soot mass measured over a plurality of respective soot loading cycles of at least one particulate filter substantially identical to the particulate filter (14), each deviation (48) in the stored database (62, 66) stands for a respective average modeled filter temperature and a respective average measured mass flow rate of nitrogen oxides in a respective one of the soot loading cycles. |
