A technical assessment is made of an automotive powerplant system using cryogenic liquid air or nitrogen as the working fluid in a powerplant operating on an open Rankine-type cycle. In this concept the cold fluid is pressurized, heat energy is added to form hot gas and then is effectively expanded to atmospheric conditions in the engine that drives the vehicle. A range of gas pressures and temperatures as well as different expansion stages and reheat configurations are evaluated. The thermodynamic results indicate that this powerplant concept can be competitive with a comparable gasoline engine to give a vehicle equal in performance, weight, range and operating cost without using imported fuel.
