Abstract: A recycling loop configuration of an exhaust gas aftertreatment system decreases a level of system-out NOx emissions of an engine. An apparatus including the configuration has an exhaust gas recycling system having a closed gas recycling loop system configured to heat gas circulating within the loop, and a blower for circulating gas within the loop. A method for operating the engine includes preheating at least one aftertreatment component of an exhaust gas aftertreatment system of the engine by exposing the component to heated gas circulating in a closed gas recycling loop.

Abstract: A powertrain system includes an engine coupled to a turbocharger and a timer, a motor generator coupled to the engine and a battery, and a controller. The controller is structured to receive data indicative of a state of charge from the battery, determine whether the state of charge is at or below a high predefined threshold, modulate control on the engine and the timer in response to determining the state of charge is above the high predefined threshold, determine whether the state of charge is above a low predefined threshold in response to the state of charge being at or below the high predefined threshold, and modulate control of the engine and the timer in response to determining the state of charge is at or below the low predefined threshold.

Abstract: A method for managing emissions from a vehicle having an aftertreatment system is provided. The method includes: receiving, by a controller, information indicative of a temperature of an aftertreatment system of the vehicle and a power output of an engine of the vehicle; comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold; comparing, by the controller, the power output to a power output threshold; and responsive to the comparisons, commanding, by the controller, an aftertreatment system heater to selectively engage and disengage to warm the aftertreatment system of the vehicle.

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: A system and method used to predict the state of health of a battery in a powertrain of a vehicle including a vehicle route profile generator arranged to generate a vehicle specific rout profile based on historical vehicle driving information, are disclosed. In one example, the system and method also include a powertrain model to convert the vehicle specific route profile to a predicted battery demand profile, and a state of health profile generator to generate a predicted state of health profile of the battery based on the predicted battery demand. In another example, the system further includes a vehicle performance manager arranged to generate a command to modify operation of the powertrain to extend battery life based on the vehicle specific route profile.

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, determine that the catalyst is operating under cold start conditions, control the bypass valve to direct exhaust gas to the PNA, determine that the catalyst is no longer operating under cold start conditions and continue to control the bypass valve to direct exhaust gas to the PNA for a predetermined duration, and after the elapse of the predetermined duration, control the bypass valve to direct exhaust gas to the catalyst bypassing the PNA. The controller is also configured to detect a high transient torque demand while the exhaust gas is provided to the PNA, and split the torque demand between the engine and an electric motor.
