    摘要： Various embodiments of an apparatus, system, and method are disclosed for reducing NOx emissions on an SCR catalyst. For example, according to one representative embodiment, an apparatus for reducing NOx emissions in an engine exhaust includes a NOx reduction target module that is configured to determine a NOx reduction requirement that includes an amount of NOx in the exhaust gas stream to be reduced on a selective catalytic reduction (SCR) catalyst. The apparatus also includes an ammonia target module that is configured to determine an ammonia addition requirement that includes an amount of ammonia added to the exhaust gas stream to achieve the NOx reduction requirement. The apparatus also includes a reductant target module that is configured to determine a reductant injection requirement that includes an amount of reductant added to the exhaust gas stream to achieve the ammonia addition requirement. The apparatus further includes a reductant limiting module that is configured to determine at least one reductant limiting condition and to limit the amount of reductant added in response to the reductant limiting condition.

    摘要： A system includes an internal combustion engine producing an exhaust stream, a particulate filtering device that treats the exhaust stream, a particulate sensor operatively coupled to the exhaust stream at a position downstream of the particulate filtering device, and a temperature sensor operatively coupled to the exhaust stream. The system includes a controller that interprets a particulate sensor particulate stability condition, interprets a particulate sensor input value and a particulate sensor temperature, compensates the particulate sensor input value in response to the particulate sensor temperature, and filters the compensated particulate sensor input value. The controller determines a soot accumulation value in response to the filtered compensated particulate sensor input value, interprets a diagnostic enable condition, and determines a particulate filter diagnostic value in response to the active diagnostic enable condition and the soot accumulation value. The controller provides the particulate filter diagnostic value to an output device.

    摘要： A system, method, and software for regenerating an adsorber connected with a flow of exhaust from an engine. An open-loop control module for ramping up and maintaining a temperature value of an adsorber to a regeneration temperature value by controlling an air fuel ratio value of an engine to operate at an open-loop controlled variable duty cycle. A closed-loop control module is operable to take control from the open-loop control module to maintain the adsorber at the regeneration temperature value if the temperature value of the adsorber deviates from the regeneration temperature value by controlling the air fuel ratio value of the engine to operate at a closed-loop controlled variable duty cycle.

    摘要： A system, method, and software for controlling regeneration and desulfurization of a NOx adsorber is disclosed. An electronic control unit is connected with an engine for selectively controlling operation of the engine between a rich operating mode and a lean operating mode. A NOx adsorber is in fluid communication with a flow of exhaust from the engine. A NOx adsorber manager module is executable by the electronic control unit to determine the need to operate in a de-NOx mode or a de-SOx mode. If the NOx adsorber manager module determines a need exists to operate in the de-NOx mode and the de-SOx mode at the same time, the NOx adsorber manager module executes the de-SOx mode.
