Abstract: A system and method of operating a waste heat recovery system for a vehicle is provided. The system includes an expander/compressor portion mechanically linked to wheels of the vehicle, the expander/compressor portion including an inlet valve and an exhaust valve. A combustion engine is provided having an exhaust portion. A working fluid path is thermally coupled between the combustion engine and a working fluid, the working fluid path being fluidly coupled to the expander/compressor portion. A boiler portion is fluidly coupled to the working fluid path, the boiler portion further being thermally coupled to the exhaust portion. An accumulator tank portion having a cavity is operative to receive and store the working fluid, the accumulator tank portion fluidly coupled to the inlet valve and the exhaust valve. A condenser is fluidly coupled to the working fluid path and the exhaust valve.
