Abstract
One embodiment relates to a waste heat recovery power drive system. The waste heat recovery power drive system includes a waste heat recovery system, which includes a heat exchanger operatively coupled to an engine so as to receive heat energy from the engine and transfer the heat energy to a working fluid. An expander is fluidly coupled to the heat exchanger to receive the working fluid from the heat exchanger. The expander is structured to convert heat energy from the working fluid to mechanical energy. A gearbox is operatively coupled to the expander. A front engine accessory drive includes a belt drive operatively coupling the gearbox to a crankshaft of the engine so as to transfer the mechanical energy from the gearbox to the crankshaft. A unitary assembly includes the front engine accessory drive, the gearbox, and the expander, and the unitary assembly is removable from the engine as a unitary component.
