Abstract:
A rotary internal combustion engine includes an outer housing and an inner housing and an enclosure defined therebetween. At least one of the outer and inner housings is rotatable relative to the other and at least two barriers are disposed in the enclosure and divide the enclosure into a combustion chamber and an exhaust chamber. At least one barrier is rotatable relative to at least one other barrier and at least one barrier comprises a retractable barrier mounted along a pivot axis and is pivotable between an extended position and a retracted position. An intake port, exhaust port, and ignition source are also provided. A method of combusting a fuel comprises rotating a drive member to expand a combustion chamber and substantially isolate the combustion chamber from an exhaust chamber, and introducing and combusting a combustion fluid and a fuel in the combustion chamber as the combustion chamber is expanding.
Abstract:
A power supply system comprises an internal combustion engine (100) and an electric motor-generator arrangement that is coupled to the internal combustion engine. The internal combustion engine (100) has a piston-cylinder assembly in which the toroidal section-shaped piston (122) and cylinder (120) are each arranged to rotate, in use, about a common axis of rotation B with respect to a stator arrangement (129) of the associated motor-generator arrangement so as to generate an electric output. The piston (122) and cylinder (120) are also arranged to form a mass-elastic system that is capable of resonance and further arranged such that combustion in the combustion chamber (121) formed between the cylinder (120) and piston (122) can cause the piston (122) and cylinder (120) to oscillate relative to each other about their common rotational axis B.
Abstract:
The invention relates to positive-displacement free-piston heat machines with variable working chambers, which could be applied as an internal or external combustion engine, compressor, pump. The machine comprises two analogous assemblies of pistons, each consisting of two or more vanes having form of symmetrical star and attached to the hub. The assemblies of pistons are placed in the cylindrical cavity that is limited by two concentric cylindrical surfaces and two planes at the ends. The vanes the different assemblies are alternately displaced in the cavity. When the assemblies of pistons swing in opposite directions, variable working chambers are got between the adjacent vanes. The external loading or driving devices are connected directly to the assemblies of pistons either by coaxial shafts, radial junctions, planar or cylindrical rings. The machine with two bodies swinging in opposite direction presents well-balanced mechanical system, and vibration of the frame is avoided.
