Abstract: The disclosure provides rotary machines that include, in one embodiment, a shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first gearbox disposed thereon defining one or more cavities therein. At least one contour is slidably received into an arcuate cavity in an exterior surface of the gearbox. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume. A gearbox mechanism consisting of gears, crankshafts, bearings and connecting rod creates an oscillatory motion 2 times per revolution such that the contour can navigate about the arcuate cavity without contacting the cavity at a high rate of rotating speed. Thus, said working volume can expand and compresses twice per rotatable shaft revolution.

Abstract: A rotary engine includes an insert having a pilot subchamber defined therein and communicating with the internal cavity of the engine. A pilot fuel injector has a tip in communication with the pilot subchamber. An ignition element extends into an element cavity defined through the insert adjacent the pilot subchamber. The element cavity is in communication with the pilot subchamber through a communication opening defined in the insert between the element cavity and the pilot subchamber. The communication opening is smaller than a portion of the ignition element adjacent the communication opening such as to prevent the portion of the ignition element from completely passing through the communication opening upon breaking off of the portion of the ignition element from a remainder of the ignition element. An outer body for a rotary engine and a method of combusting fuel in a rotary engine are also provided.

Abstract: Aspects of the present disclosure are directed to apparatuses and methods involving an engine and/or motor having piston lobes that rotate with a drive shaft or shafts, which may be implemented with a toroidal-based engine housing. As may be implemented with some embodiments, an apparatus includes drive shafts having a common axis of rotation, with each drive shaft operable to rotate independently of the other drive shaft. The housing extends around the drive shafts, and defines a sidewall of a chamber having inlet and exhaust ports. Clutch bearings limit rotation of the drive shafts to a common rotational direction. One or more piston lobes are connected to each drive shaft, with each piston lobe being disposed within the chamber and operable to move circumferentially within the chamber about the axis of rotation, with the drive shaft to which it is coupled.

Abstract: A guided-vane rotary internal combustion engine including a plurality of working chambers which are separated from one another by way of vane assemblies which rotate with a rotor assembly about an axis employs a rotor assembly having a plurality of sectors wherein each sector is associated with a corresponding working chamber and a plurality of spark plugs wherein each spark plug is mounted within a corresponding sector for igniting an air/fuel mixture contained within a corresponding working chamber. A rotor disk is mounted upon the rotor assembly for rotation therewith and acts as a distributor through which energizing charges are conducted to the spark plugs. In addition, a controller is utilized for selectively activating or de-activating the working chambers of the engine upon the occurrence of a predetermined event.
