Abstract: A method includes providing a zeolite material including a plurality of active sites. The plurality of active sites are bound to a plurality of hydrogen ions. The method includes exchanging at least a portion of the plurality of hydrogen ions with a plurality of copper ions, thereby forming a first amount of Z2Cu active sites that include copper (Cu2+) ions bound to the zeolite material and a first amount of ZCuOH active sites bound to copper hydroxide ions bound to the zeolite material. The method includes heating the zeolite material to a heat treatment temperature for a predefined time period to transform the zeolite material into a heat treated zeolite material. The heat treated zeolite material includes a second amount of Z2Cu active sites greater than the first amount of Z2Cu active sites and a second amount of ZCuOH active sites less than the first amount of ZCuOH active sites.

Abstract: Systems and methods for controlling and managing ammonia slip are provided. A method includes: receiving, by a controller, data regarding operation of an exhaust aftertreatment system; determining, by the controller, that a condition for ammonia slip is present based on the data regarding operation of the exhaust aftertreatment system; determining, by the controller, that a condition for ammonia storage is present based on the data regarding operation of the exhaust aftertreatment system; and, commanding, by the controller, a heater to activate and warm a component of the exhaust aftertreatment system to reduce the stored amount of ammonia.

Abstract: A system includes a catalyst for receiving and treating exhaust gas generated by an engine, a passive NOx adsorber (PNA) positioned upstream of the catalyst, a bypass valve positioned upstream of the catalyst and the PNA, and a controller. The controller is configured to: while controlling the bypass valve to direct exhaust gas to the PNA, detect a torque demand that is greater than a threshold value; responsive to detecting that the torque demand is greater than the threshold value, engage a motor, coupled with a battery system, with a drive shaft of the system to meet at least a portion of the torque demand; in response to the engagement of the motor with the drive shaft not meeting all of the torque demand, engage the engine with the drive shaft to meet a remainder of the torque demand.

Abstract: The enclosed disclosure relates to vehicle systems in which an engine, a particulate filter fluidly coupled with the engine, a selective catalytic reduction (SCR) system fluidly coupled with the engine downstream of the particulate filter, an electrical heating device implemented with the particulate filter, and a controller operatively coupled with the engine and the electrical heating device, are implemented. The controller can detect, when the engine is turned off, a condition for turning on the engine, detect a temperature of the particulate filter of the SCR system, activate the electrical heating device in response to the detected temperature being below a lower temperature threshold, and turn on the engine in response to the detected temperature being at or above the lower temperature threshold.

Abstract: Systems and methods for controlling a hybrid system. For example, a computer-implemented method includes determining a system temperature zone of the aftertreatment system as being in: a first temperature zone below a first temperature threshold, a second temperature zone from the first temperature threshold to a second temperature threshold, or a third temperature zone above the second temperature threshold; determining a power demand corresponding to the operation of the hybrid system as being in: a first power demand zone if the power demand is below a power threshold, or a second power demand zone if the power demand is equal to or greater than the power threshold; and determining a control strategy based at least in part on the determined system temperature zone and the determined power demand.

Abstract: A method includes determining, by a controller, that a transient event for a hybrid vehicle is occurring; determining, by the controller, an increase of power demand for the hybrid vehicle based on the determined transient event; directing, by the controller, an amount of power from an electric motor of the hybrid vehicle to a powertrain of the hybrid vehicle based on the increase in power demand, the amount of power from the electric motor determined based on at least one of a state of charge of a battery of the hybrid vehicle; and increasing, by the controller, an amount of power from an engine of the hybrid vehicle as a power output from the electric motor decays to avoid an engine power output spike from the engine based on the determined increase in power demand.

Abstract: A method of recovering selective catalytic reduction catalysts relates to metal-Zeolite based catalysts. A selective catalytic reduction catalyst service event where a metal-Zeolite based selective catalytic reduction catalyst of an exhaust aftertreatment system may perform below a threshold level of performance is determined. The selective catalytic reduction catalyst then exposed to a recovery fluid selected to facilitate movement of metal ions.
