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.

摘要： An amount of particulate matter accumulated in a particulate filter of an exhaust system is estimated by preloading a memory location with a plurality of hybrid models. Each hybrid model estimates an amount of particulate matter accumulated in the particulate filter between a pair of operating points. An estimated amount of particulate matter accumulated in the particulate filter is stored in the memory location for each hybrid model. Each hybrid model is ranked based on estimation accuracy during operating conditions and the highest ranked hybrid model is selected. The estimated amount of particulate matter accumulated in the particulate filter corresponding to the highest ranked hybrid model is added to the soot estimation value stored in the memory location that corresponds to a ranked hybrid model to provide a soot estimation value of a cumulative estimated amount of particulate matter contained in the particulate filter for the ranked hybrid model.

摘要： An exhaust diagnostic system comprises a selective catalyst reduction (SCR) component testing module, an exhaust stream temperature management module, and a test enabling module. The component testing module executes an SCR component efficiency test. The exhaust stream temperature management module adjusts a temperature of the SCR component to a predetermined temperature range. The test enabling module executes a process for depleting a reductant load and subsequently initiates an SCR component efficiency test while the temperature of the SCR catalyst is within the predetermined temperature range. A method for diagnosing an exhaust system comprises determining an efficiency of an SCR component and selectively adjusting a temperature of the SCR component to a predetermined temperature range. The method also includes executing a process for depleting a reductant load and initiating an SCR component efficiency test while the temperature of the SCR component is within the predetermined temperature range.

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 system for the treatment of exhaust gases includes an engine, an exhaust system, and a controller. The exhaust aftertreatment system is configured to accept exhaust gas from the engine and includes a particulate filter configured to filter particulate matter from the exhaust gas. A controller is configured to determine an actual temperature of the particulate filter during a regeneration process and analyze the actual temperature relative to a temperature deviation threshold. The controller is configured to adjust the temperature deviation threshold in real time based, at least in part, on an operating condition of the engine and a mass flow of the exhaust gas.
