Abstract: The disclosure provides rotary machines that include, in one embodiment, a rotatable shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first hub disposed thereon with a plurality of cavities. At least one contour is slidably received into an arcuate cavity in an exterior surface of the hub. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume.

Abstract: An internal combustion engine includes a solid ring having a central plane bisecting the ring into a first side and a second side. A first pair of diametrically opposed pistons is located on the first side. A second pair of diametrically opposed pistons are located on the second side. The first pair of diametrically opposed pistons are offset from the second pair of diametrically opposed pistons by 90 degrees.

Abstract: A rotary engine has a rotor with a rotor pocket for receiving air-fuel mixture that is combusted therein to propel the rotor within the housing. The rotary engine may have one or more intake spray injectors that spray fuel into the rotor pocket and onto the rotor face within the intake chamber to effectively cool the rotor pocket and rotor face. An air channel extension of the rotor pocket may be configured in the housing and/or in the rotor to extend from the compression chamber into the ignition-combustion chamber to relieve some pressure in the trailing compression chamber of a rotor face to minimize negative work. A supplemental air-fuel conduit may be configured to supply high-pressure gas from the compression chamber to an ignition injector(s). A thrust nozzle may be configured within the rotor pocket to direct combustion gases therethrough to propel the rotor and increase efficiency.

Abstract: A rotary internal combustion engine having a cover plate, and stator plate having a bore with teeth and a primary cog that is larger than the teeth. A main rotor having a partially-circular cut-out. A gear rotor is disposed within the cut-out, having teeth that engage the teeth of the stator ring. A base plate has inlet ports for receiving fuel, air, and spark, where an ignition of the fuel and air by the spark creates a high pressure zone that drives the main rotor and the gear rotor rotationally within the stator ring, and an outlet port for exhausting spent fuel and air.

Abstract: A rotary engine, parts thereof, and methods associated therewith is provided. The engine is modular and adjustable to accommodate a variety of requirements and preferences. The system includes a combustion assembly having a housing and a power rotor positioned therein. The power rotor rotates in a first direction from the beginning of each combustion process through the end of each exhaust process. The system also includes a compression assembly linked to the combustion assembly such that the compression rotor rotates in the first direction from the beginning of each intake process through the end of each compression process. A tank assembly in fluid communication with the compression assembly and the combustion assembly provides stability to the system while eliminating or otherwise reducing transitional loses.

Abstract: The invention comprises a rotary engine apparatus and method of use thereof, where the rotary engine comprises multiple injection ports. Optional injection ports include a first port in an expansion chamber, a second port in the expansion chamber after a first rotation of the rotor, a third port into the expansion chamber after a second rotation of the rotor, a fourth port from a fuel path through a shaft of the rotary engine, and/or a fifth port into a rotor-vane chamber between the rotor and a vane. Optionally, one or more of the injection ports are controlled through mechanical valving and/or through electronic and/or computer control.
