Rotary-vane internal combustion engine.
Rotary-vane internal combustion engine compared to a modern piston engines has thermal efficiency up to 60%. Its effective efficiency by 10-12% higher than that of contemporary piston engines. In all modes of operation rotary vane engine lower fuel consumption than the reciprocating engine. Uses almost all types of fossil fuels.
Technology is in the process of development and is awaiting funding!

Design features of rotary vane machine
Rotary-vane internal combustion engine consists of two module with a shared output shaft. Each module consists of a rotary vane group and the motion converting mechanism. In the case of rotary vane group provides a window for connection pipe with heater and cooler. The conversion mechanism of the movement converts oscillatory rotational motion of the rotors with blades rotated by the output shaft.
Maintaining the frequency of rotation is provided by the automatic control system controls pressure of the working fluid in a rotary vane group.
The motion converting mechanism converts the vibrational-rotational motion of the rotors with blades rotated by the output shaft. The mechanism provides the required law of change of working volume.
Both modules are filled with a working medium (gas) under the initial pressure. The working volume of the modules are connected by system of pipelinespassing through the heater and cooler.
In four working volumes of each module simultaneously carried out the thermodynamic cycles of a Stirling cycle: intake, compression, heat supply, stroke, release, dissipation. Due to the angular shift of the modules relative to each other pumping the working fluid through the heater and cooler, which allows the conversion of thermal energy into mechanical work.
The diagram of the blade counterclockwise unevenly, then accelerating, then slowing down. As a result, in the lower right quadrant is the intake stroke, in the upper right quadrant – the compression stroke in the “top dead point” – ignition of the mixture, in the upper left sector working stroke, in the lower left sector – the exhaust stroke. This sequence of cycles is repeated for each full revolution of the rotor. Thus, the entire four-stroke cycle is performed during one revolution of the rotor shaft.
The advantages compared to contemporary piston engines:
– thermal efficiency is up to 60%,
– effective efficiency 10-12% higher than current reciprocating engines,
– for all operating modes fuel consumption is less than the piston engine,
– the use of virtually all fossil fuels,
– power control by varying the pressure of the working fluid and temperature
– easy starting in any temperature environment,
– high service life,
– small number of parts,
– simplicity of construction. No complicated timing mechanism. More sophisticated
efficient gas exchange promotes better fuel combustion and less toxicity
– good balance,
– several times better specific weight and dimensions,
– incomparably low consumption of lubricants,
significantly below the cost of production.
Design features of rotary-vane machine:
– contains 60% fewer parts than the connecting rod-piston engine,
– no complicated parts such as the crankshaft and camshafts
– does not contain valves, springs, tappets, rods,
– has a symmetrical design, thus the engine is balanced,
– two rotor blades have the same combustion chamber and carry out work equivalent to work an 8-cylinder engine
– has a simple cylindrical shape.
