Abstract: Systems and methods for driving an accessory of a vehicle. The system includes a power take-off (PTO) device, a mechanically driven accessory, a battery, and power conversion circuitry electrically connected to the battery. The system also includes a first electric motor mechanically coupled to the PTO device and a second electric motor mechanically coupled to the mechanically driven accessory. The system further includes an engageable mechanical connector that, when engaged, mechanically couples the PTO device and the mechanically driven accessory.

Abstract: Methods of improving SCR performance in heavy duty vehicles may use multiple interdependent control techniques to increase engine exhaust temperatures in a fuel efficient manner. One method combines cylinder deactivation and mechanical loading of an engine by an electrical generator used to input energy into an exhaust stream to manipulate the exhaust temperature through the combined effect of modified air-to-fuel ratio and supplemental energy input. In particular, cylinder deactivation may be used to modify the engine air flowrate and the electric generator may be used to apply mechanical load on the engine to manipulate the engine fuel flow rate to control the engine air-to-fuel ratio and thereby increase exhaust temperatures. The exhaust temperatures may be further increased by using the electrical generator to add the energy generated as input energy to the exhaust stream.
