KAZANTSEV PISTON ENGINE Russian patent published in 2011 - IPC F02G3/02 

FIELD: engines and pumps.

SUBSTANCE: piston engine includes converter for conversion of energy of working medium to mechanical energy, fuel pump; at that, hydraulic pump is equipped with external combustion chamber which is located outside the converter, steam generator and compressor; at that, compressor is pneumatically connected to external combustion chamber which is connected through steam generator to converter, and fuel pump is hydraulically connected to external combustion chamber, and hydraulic pump is hydraulically connected to steam generator. External combustion chamber is arranged in steam generator, equipped with gas chamber separating combustion products from steam. At that, gas chamber has the volume which is more than twenty cyclic volumes of converter. Steam generator has the volume which is more than twenty cyclic volumes of converter. Air cooler is installed between compression steps of compressed air. Engine is equipped with external liquid cooling system which is hydraulically connected to hydraulic pump, heat insulating jacket and turbo-compressor. Turbo-compressor is pneumatically connected to converter and compressor, which are combined into one unit. Converter has oil case which is separated from compressor and equipped with outlet openings. Engine has one external combustion chamber per several converters. Supply of fuel, cooling liquid and working medium is controlled. Converter is made in the form of Kazantsev pneumatic engine, or in the form of Kazantsev adiabatic engine, or in the form of Diesel engine, or in the form of Wankel engine, or in the form of rotary engine, and in the form of Stirling engine. Compressor is piston-type or turbine-type or centrifugal.

EFFECT: invention provides improvement of engine power and efficiency, fuel economy, and the design is simplified.
