FIELD: mechanical engineering; turbocharged engines.
SUBSTANCE: proposed internal combustion engine with gas turbine supercharging has heat exchanger, piston engine with gas turbocharger, turbine and compressor of which are installed on one shaft and connected by pipelines to intake and exhaust ducts of engine, respectively. Gas turbocharger has turbogas expansion machine with additional compressor. Additional heat exchanger for cooling exhaust gases is installed at inlet of compressor coupled with exhaust ducts of turbine of turbogas-expansion machine.
EFFECT: increased efficiency of gas turbo charger and efficiency of engine.
