A hydrogen G-cycle rotary vane internal combustion engine has a sodium vapor chamber transferring excess combustion heat into combustion chambers. An active water cooling system captures heat from the engine housing stator, rotor, and sliding vanes and transfers it back into the combustion cycle by premixing it with hydrogen to reduce peak combustion temperature and with an early an late stage combustion chamber injection to help transfer heat from the sodium vapor chamber, to control chamber temperature, and to increase chamber vapor pressure. A combustion chamber sealing system includes axial seals between the rotor and the stator, vane face seals, and toggling split vane seals between the outer perimeters of the sliding vanes and the stator. Sliding vanes reciprocate laterally in and out of the rotor assisted by a vane belting system. A thermal barrier coating minimizes heat transfer and thermal deformation. Solid lubricants provide high temperature lubrication and durability.

ROTARY PISTON INTERNAL COMBUSTION ENGINE

Rotary internal combustion engine - has cam formed on surface of rotating piston to actuate sliding vanes

A rotary internal combustion engine has a cylinder (1) housing a rotating piston (2). The piston (2) has a cam (5) formed on its surface such that there is only a minimum clearance between the tip of the cam and the bore of the cylinder (1). As the piston (2) rotates, a mixture of air and fuel is drawn in through the port (12) and when the cam (5) has passed the port (12) the mixture is compressed and forced into the combustion chamber (6). The cam (5) operates the sliding vanes (8) which trap the mixture in the combustion chamber where it is ignited. The gas formed by combustion expands and exerts a force on the radial face of the cam (5) to drive the piston. The exhaust gases then pass out through the port (10).

Rotary Piston Engine with Solid Particle Fuel Capability

Axially protruding and centrally cool able pistons rotate within a cylindrical main chamber. Each piston is individually kinetically linked to a flywheel.

Augmented Compression Engine (ACE)

Unlike similar internal combustion engines that vary the fuel-air mixture, the Augmented Compression Engine (ACE) first and foremost sets and maintains an optimal stoichiometric fuel to air ratio, relying upon various implementations of Boyle's law to attain ignition of the stoichiometric fuel-air mixture in the combustion chamber while varying quantities of the fuel-air mixture to adjust output power. An ACE uses fuel-air mixed prior to attainment of auto-ignition temperatures in the combustion chamber, compresses it and achieves ignition by an ignition source or use of compression heating the fuel-air to its auto-ignition temperature. Since different quantities of the fuel-air mix are needed for different loads (power outputs), to maintain reliable ignition the ACE uses one or more of: varying intake pressure; valve timing; recycled exhaust or other implementations of Boyle's law for adjusting compression such as, injected matter, modifying fuel or changing of combustion chamber volume.

Separated rotary engine

PURPOSE: A separated rotary engine is provided to prevent the size and weight increase of an engine due to a diaphragm valve and a spring, by employing a diaphragm valve which moves around a hinge point within a housing. CONSTITUTION: A separated rotary engine comprises hinged vanes(9,9'). One ends of the hinged vanes are secured on a hinge point(20,20') inside of a housing(1,1') while the other sides contact rotor exteriors(4,4'). As the rotors rotate, the hinged vanes pivot around the respective hinge points within the gap between the housing interior and the rotor exterior. The pressure of combustion gas and compressed air act in the direction where one ends of the hinged vanes closely contact the rotor exterior.
