Rotary piston internal combustion engine

An internal combustion engine system that operates with high efficiency when providing power to a vehicle or accessory equipment, the internal combustion engine system comprising:

• an engine assembly with multiple combustion chambers arranged in a toroidal geometry, each combustion chamber being delimited by piston heads positioned on multiple primary members that move in opposite directions and by a cavity established within a cylinder liner;
• a plurality of crankshafts positioned within the diameter of the toroidal path of the primary members;
• an intermediate sub-assembly comprised of multiple sliding components that facilitates the movement of the primary members, a flywheel coupled to one crankshaft to force cooling air through the engine assembly;
• a pulley connected to another crankshaft for use in providing the power necessary to drive the vehicle or accessory equipment;
• and multiple injectors, each injector adapted to inject fuel into the combustion chamber;
• exhaust ducting coupled to each cylindrical liner for removing air from the engine assembly;
• inlet ducting coupled to each cylindrical liner for supplying air to the engine assembly;
• and
• a turbocharger connected to the exhaust ducting and the inlet ducting;
• the turbocharger capable of supplementing the air in the exhaust ducting to ensure that the air in the in-let ducting is at a constant pressure;
• wherein the intermediate sub-assembly further comprises a first intermediate member including multiple T-members and first upper and lower extensions, a second intermediate member comprising second upper and lower extensions that couple with the first upper and lower extensions, a halter sub-assembly including multiple planar bearings, and at least one slider sub-assembly;
• wherein the slider sub-assembly is adapted to slidably move within the intermediate sub-assembly with a low level of friction;
• and
• wherein the halter sub-assembly acts as a horizontal frictional bearing, and wherein the slider sub-assembly and the halter sub-assembly slide linearly along the multiple T-members.

An engine assembly for use in providing power to a vehicle or accessory equipment, the engine assembly comprising:

• a piston sub-assembly;
• the piston sub-assembly having an upper cylinder liner, a lower cylinder liner, a first primary member including a first and a second piston head, and a second primary member including a first and a second piston head;
• the upper and lower cylinder liners each having a cavity with a wall adapted to delimit a combustion chamber within the cylinder liner;
• each combustion chamber defining at least a section of a torus;
• the first piston head of both primary members adapted to be received by the cavity in the upper cylinder liner to further delimit said combustion chamber;
• the second piston head of both primary members adapted to be received by the cavity in the lower cylinder liner to further delimit said combustion chamber;
• an intermediate sub-assembly;
• the intermediate sub-assembly adapted to facilitate the movement of the first and second primary members in opposite directions along a predetermined toroidal path;
• a top plate having multiple openings;
• a first crank shaft having a central axis;
• a flywheel;
• the flywheel being supported by the top plate and rotatable by the first crank shaft in order to provide air flow through the engine;
• a base plate having multiple openings;
• a second crank shaft having a central axis;
• a pulley;
• the pulley being supported by the base plate and rotatable by the second crank;
• the pulley being adaptable to provide power to the accessory equipment;
• wherein the radial motion in the engine assembly is aligned with the central axis of the first or second crank shafts;
• wherein the intermediate sub-assembly further comprises a first intermediate member including multiple T-members and first upper and lower extensions, a second intermediate member comprising second upper and lower extensions that couple with the first upper and lower extensions, a halter sub-assembly including multiple planar bearings, and at least one slider sub-assembly;
• wherein the slider sub-assembly is adapted to slidably move within the intermediate sub-assembly with a low level of friction;
• and
• wherein the halter sub-assembly acts as a horizontal frictional bearing, and wherein the slider sub-assembly and the halter sub-assembly slide linearly along the multiple T-members.
