HEAT ENGINE; METHOD OF OPERATION AND DESIGN VERSIONS Russian patent published in 2000 - IPC

FIELD: mechanical engineering; road, water and air transport, stationary ground and space power plants. SUBSTANCE: invention provides description of operation and design versions of heat engine with recuperation of heat of exhaust gases in process of compression. Designs of four-stroke and two-stroke piston engines and Wankel (rotory-piston) engines are considered. Engines can be made with external heating and closed cycle, or with internal combustion when heater is made in form of combustion chamber with fuel nozzle, and surrounding atmosphere is used as cooler. Different versions of heat exchange devices (regenerators, recuperators, heaters) are considered. EFFECT: increased fuel economy, provision of functioning of heat exchange devices as catalyst converter and muffler. 9 cl, 20 dwg
