FIELD: power engineering and mechanical engineering; engines operating at cycle process. SUBSTANCE: gas-liquid solution is used as working medium which features reverse solubility to temperature. During first phase of operation, volume expands, pressure drops and mechanical work is done at expansion. In process of volume increasing and pressure dropping gaseous is liberated accompanied by liberation of heat, so supplied heat can be lower. In process of compression gas is dissolved in liquid which is accompanied by consumption of heat which leads to reduction of compression work. EFFECT: enhanced thermodynamic efficiency of cycle. 4 dwg
