    Abstract: An internal combustion engine system includes an engine and an aftertreatment system that is connected to the engine to receive exhaust flow from the engine. The aftertreatment system includes a passive storage device for passively storing NOx and/or hydrocarbons produced by the engine during cold start and low temperature operating conditions, and a NOx reduction catalyst downstream of the passive storage device for receiving the NOx released from the passive storage device when temperature conditions in the exhaust flow and/or NOx reduction catalyst are above an effective temperature for NOx reduction. Diagnostics of the passive storage device and/or a sensor downstream of the passive storage device are contemplated that are based at least in part on an expected sensor output in response to a storage mode of operation or a release mode of operation of the passive storage device. Furthermore, reductant injection control is provided in response to a NOx amount released from the passive storage device.

    Abstract: A vehicle system includes an engine, a transmission, a differential, and a waste heat recovery (WHR) drive that converts thermal energy into mechanical and electrical energy. The WHR drive can include a WHR power unit structured to convert thermal energy into rotation of a WHR drive shaft. A motor/generator having a motor/generator shaft can selectively operate as a motor or a generator. A mechanical linkage is structured to selectively link an output shaft to one of the WHR drive shaft and the motor/generator drive shaft independently of the other of the WHR drive shaft and the motor/generator drive shaft. The output shaft is selectively coupled to one of the engine, the transmission, or the differential. The vehicle system may also include a traction motor to provide drive to the vehicle. The output shaft can be selectively coupled to the traction motor or the engine.

    Abstract: A method of calibrating a control system based on a parametric value of a component. The method includes receiving a current from a component of the control system. The component is communicatively coupled to a controller and has a parametric resistor with a parametric resistance value correlating to a parametric value associated with the component. The method further includes determining the resistance value of the parametric resistor by measuring a parametric voltage rating from the current. The method further includes mapping the resistance value to the parametric value associated with the component. The method further includes generating a calibration data set. The calibration data set is based on calibrating the control system to calibrate for the parametric value. The method further includes transmitting a signal to the component. The signal is based on the calibration data set and is configured to calibrate operation of the component.
