Abstract

In a method for recovering energy from the heat dissipated by an internal combustion engine and to an internal combustion engine wherein the pressure and temperature of a liquid working medium are increased from a lower process pressure and a first temperature to an upper process pressure at which the working fluid is heated to a second temperature whereby it is converted to a gaseous phase; the working medium is then expanded back to the lower process pressure whereby mechanical power is generated and the working medium is converted back to a liquid phase, the upper process pressure being adjusted in such a way that the working medium is expanded into the wet steam area close to the saturated steam limit.
