    Abstract: Systems include a prime mover that generates power for a mobile vehicle; a power converter that receives a portion of the generated power, and provides configured electrical power to an aftertreatment heater device configured to selectively heat an exhaust fluid of the prime mover; at least one aftertreatment component positioned downstream of the aftertreatment heater device, and configured to treat a constituent of the exhaust fluid; and a controller including an operating conditions circuit structured to interpret an operating parameter of one of the power converter, the aftertreatment heater device, the prime mover, or the exhaust fluid; a heater management circuit that determines a heating power value in response to the operating parameter; and a heater control circuit that provides a heating command in response to the heating power value; and wherein the power converter is responsive to the heating command to heat the exhaust fluid of the prime mover.

    Abstract: A rocker arm assembly comprises a first arm, a second arm, and a latch assembly. The first arm comprises a main cam interface end, a body comprising a shaft port configured to pivot on a rocker shaft, and a valve end configured to lift and lower when the main cam interface end is acted on by a cam lobe. The second arm is overlaid on the first arm. The second arm comprises a secondary cam interface end, a latch lip end, and a shell connecting the latch lip end and the secondary cam interface end. The shell is configured to pivot relative to the first arm. The latch assembly is mounted to the body. The latch assembly is configured to selectively latch and unlatch the first arm with respect to the second arm.

    Abstract: A method for controlling vehicle speed comprises selecting an engine speed profile for a vehicle. Road grade data is received and processed to determine a road grade for the vehicle. Vehicle speed data is received and processed to determine a vehicle speed for the vehicle. A cylinder deactivation mode for a valvetrain of a multi-cylinder engine of the vehicle is selected. The cylinder deactivation mode comprises deactivating one or more intake valve, exhaust valve, and fuel injection for one or more cylinder of the multi-cylinder engine. The selected cylinder deactivation mode provides a controlled deviation from the selected engine speed profile at the road grade and vehicle speed.

    Abstract: A combined exhaust and engine brake rocker arm assembly configured to selectively open first and second exhaust valves, includes a rocker arm body, an exhaust rocker arm assembly formed in the rocker arm body, and an engine brake rocker arm assembly formed in the rocker arm body and configured to operate in a collapse mode and a rigid mode. The exhaust rocker arm assembly is configured to selectively engage a valve bridge to open the first and second exhaust valves, and the engine brake rocker arm assembly is configured to selectively engage the valve bridge to open only the first exhaust valve.
