COMBINATION INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: combination internal combustion engine has supercharging compressor drive turbine and energy converter connected to gas outlet branch pipe of turbine. According to invention, energy converter is made in form of thermal compression compressor with inlet and outlet branch pipes and impeller with radial blades placed inside, and also stationary distributing member placed inside impeller. High-pressure inlet port and high- pressure outlet port are connected by main line accommodating recovery circuit heat exchanger. Compressed working medium takeoff branch pipe is arranged on section adjoining high-pressure outlet [port, said branch pipe connected with cylinder exhaust gases discharge main line. Energy converter makes it possible to increase flow of working medium through turbine owing to use of atmospheric air with supply of exhaust gas heat. EFFECT: increased engine efficiency owing to recovery of exhaust gas heat. 2 cl, 1 dwg
