    Abstract: An aftertreatment system comprises a first passageway having a first temperature and a second passageway having a second temperature different than the first temperature. A turbine is disposed downstream from the first passageway and upstream from the second passageway. The turbine is in fluidic communication with the first passageway and the second passageway. The turbine is structured to receive an exhaust gas from the first passageway, generate energy using the exhaust gas flowing through the turbine and communicate the exhaust gas to the second passageway. The aftertreatment system also includes an insertion device structured to insert an exhaust reductant into the first passageway. A selective catalytic reduction system is configured to receive the exhaust gas from the second passageway and treat the exhaust gas. The first temperature can be higher than the second temperature.

    Abstract: Systems, methods and apparatus are disclosed for disabling control of one or more outputs of an internal combustion engine system in response to an engine-out NOx sensor during a high frequency pressure pulsation associated with the exhaust gas at the engine-out NOx sensor. A high frequency pressure pulsation event may be determined in response to a pressure sensor measurement, or in response to operating parameters of one or more components of the system indicating high torque output conditions, and/or by a blade position of a turbine adjacent the NOx sensor indicating passage of the exhaust gas pressure pulsations to the NOx sensor.

    Abstract: An apparatus is disclosed, including an exhaust conditions module structured to interpret a diesel particulate filter (DPF) delta pressure value, a flow balance correlation, a NOx input value, and an exhaust flow rate value. A flow determination module is structured to determine a flow imbalance value in response to the DPF delta pressure value, the flow balance correlation, and the exhaust flow rate value. A reductant determination module is structured to determine a first reductant injection command and a second reductant injection command in response to the flow imbalance value and the NOx input value.
