    摘要： A method for controlling regeneration within an after-treatment component of a compression-ignition engine comprises calculating an initial estimate of accumulated particulate matter based on a pressure-based soot accumulation model and a pressure drop index indicative of a decrease in pressure across the component. An adjusted estimate of accumulated particulate matter in the component is calculated based on the initial estimate and a soot prediction error inherent in the soot model. The adjusted estimate is compared to a predetermined threshold associated with the after-treatment component, and a remedial action is initiated when the adjusted estimate of accumulated particulate matter in the after-treatment component exceeds the predetermined threshold. The pressure-based soot accumulation model may be configured to predict soot accumulation in the absence of passive regeneration, and an adjusted kinetic burn model may be used to estimate a quantity of soot disposed through passive regeneration.

    摘要： A treatment control system comprises a monitoring module and an injection control module. The monitoring module monitors an exhaust temperature and an exhaust flow rate in an exhaust system of a vehicle. The injection control module controls injection of a dosing agent into the exhaust system for first and second regeneration events of a diesel particulate filter (DPF) and selectively injects a predetermined amount of the dosing agent into the exhaust system between the first and second regeneration events when the exhaust temperature is greater than a predetermined temperature and the exhaust flow rate is greater than a predetermined flow rate.

    摘要： A method for monitoring a discrete substrate element from an ammonia-selective catalyst reduction device configured to treat an exhaust gas feedstream of an internal combustion engine includes monitoring amounts of ammonia that are adsorbed, desorbed, and oxidized and an amount of ammonia that is consumed in reducing NOx in the exhaust gas feedstream from the discrete substrate element. An amount of ammonia consumption for the discrete substrate element is determined based on the amount of ammonia that is oxidized and the amount of ammonia that is consumed in reducing NOx in the exhaust gas feedstream. The amount of ammonia that is adsorbed and the amount of ammonia that is desorbed for the discrete substrate element are compared and the amount of ammonia consumption for the discrete substrate element is adjusted when the amount of ammonia that is adsorbed is less than the amount of ammonia that is desorbed.

    摘要： A particulate estimation system is configured for estimating a mass of particulate matter accumulated in a particulate filter of an exhaust system. The system includes a memory device, an interface, and a controller. The memory device stores a plurality of modules. Each of the plurality of modules is configured to uniquely estimate an amount of the particulate matter accumulated within the particulate filter over a period of time. The interface receives a plurality of input signals. The plurality of input signals correspond to a plurality of modules that are stored in the memory device. The controller derives a hybrid model based on the input signals. The hybrid model is configured to provide an output that is an estimation of the amount of particulate matter accumulated within the particulate filter over the period of time as a function of the plurality of input signals.

    摘要： A method of monitoring soot mass in a particulate filter of an exhaust system includes determining a pressure differential across the filter, obtaining a first soot mass estimate by fitting the determined pressure differential to a first stored database of measured or modeled pressure differentials and corresponding measured soot masses taken during filter regeneration using a substantially similar filter previously loaded following a complete filter regeneration, and obtaining a second soot mass estimate by fitting the determined pressure differential to a second stored database of measured or modeled pressure differentials and corresponding measured soot masses taken during filter regeneration using a substantially similar filter loaded following an incomplete filter regeneration. Actual soot mass is estimated by calculating a weighted sum of the first and second soot mass estimates with weighting based on operating parameters indicative of regeneration efficiency. A monitoring system for a particulate filter is also provided.
