Abstract

Systems and methods for operating a thermodynamic engine are disclosed. The systems and methods may effect cyclic motion of a working fluid between hot and cold regions of a thermodynamic engine and inject a dispersible material into the working fluid at the hot or cold region during a heat-addition or heat-rejection process. The system and methods may also evacuate the dispersible material from the hot or cold region.
