Method for converting thermal energy into mechanical work or vice versa in e.g. internal combustion engine, involves guiding thermodynamic machine to initial condition during conversion of mechanical work into thermal energy

摘要

The method involves causing temperature difference between a primary working medium and a secondary working medium of a thermodynamic machine (1) i.e. heat engine. Heat is transferred to the working media e.g. nitrogen, carbon dioxide and saturated steam, for compensating the temperature difference, and thermal energy is supplied to the media from surroundings. The machine is guided to an initial condition during the conversion of mechanical work into thermal energy with the output of the thermal energy, where the media is in equilibrium with the surroundings of the machine in the condition. An independent claim is also included for a thermodynamic machine for converting thermal energy into mechanical work comprising a chamber with primary working media.
