METHOD OF OPERATION OF VOLUME DISPLACEMENT HEAT ENGINE AND DESIGN OF VOLUME DISPLACEMENT HEAT ENGINE Russian patent published in 2004 - IPC

FIELD: power engineering. SUBSTANCE: according to invention internal energy of compressed gaseous working medium is increased owing to received heat and it is converted into useful work by cyclic action of expanding gaseous working medium in working chamber onto movable energy converter. Internal energy of compressed gaseous working medium is increased by communicating working chamber at internal: end of compression stroke - beginning of expansion stroke, with container with gaseous heat carrier whose temperature and pressure exceed temperature and pressure of gaseous working medium in working chamber, in combination with supply of heat to gaseous heat carrier in container to restore said excess before subsequent communication of working chamber with container. EFFECT: reduced consumption of fuel in engine with external supply of heat. 4 cl, 1 dwg
