ROTARY HEAT ENGINE, CONTROL METHOD THEREOF, AND SET OF ELEMENTS FOR FORMING SUCH A MOTOR BY TRANSFORMING AN EXISTING MOTOR

摘要

A rotary external combustion engine wherein energy is supplied to a working space of the engine by direct injection into the stator of liquid water at a high temperature and pressure. The water acts as a heat-transfer medium. Some of the liquid water spontaneously vaporizes on injection, during the rotor. Liquid water is exhausted from the working space and recycled to an external heat exchanger for reheating prior to reinjection. The engine is capable of a thermal efficiency greater than that of the Rankine cycle.
