This patent discloses thrust vectoring ignition chamber engine in which ignition chamber is an annular cylinder having nozzles mounted such that during fuel suction phase they are sealed and during ignition of fuel they are unsealed so that hot jets of ignited fuel escaping through nozzles cause coupled rotatory motion on the ignition chamber. Engine uses specially designed dwell barrel cam mechanism for two phase suction and compression of fuel which facilitates the separation of fuel valve from ignition chamber. Flywheel mounted on extension of ignition chamber functions as output of the engine. Timing of electrically controlled nozzle seal and fuel valve can be adjusted so that each half rotation of flywheel completes three phases namely fuel/air suction, compression and combustion, instead of two rotations as required in engine according to prior art. This engine can give improved power boost by firing for every half revolution.

An engine includes a housing defining an annular bore and a piston assembly disposed within the annular bore. The engine also includes a rotary valve comprising a circular faceplate and a wall structure disposed at an outer periphery of the faceplate, a portion of the at least one rotary valve disposed within the annular bore, and a rotary drive mechanism connected to the rotary valve and configured to rotate the rotary valve between a first position to align an opening of the wall structure with the annular bore to allow the piston of the piston assembly to travel within the annular bore from a first location relative to the rotary valve to a second location relative to the rotary valve and a second position to define a chamber relative to the piston of the piston assembly at the second location.

A rotary roller motor is disclosed herein. The rotary roller motor is a four-stroke internal combustion engine, wherein the rotor “rolls” around the inside of the engine block. The rotor is a two-part rotor having an inner part with a shaft and an offset circular lobe, and an outer rotor fit around the lobe. Two barriers are provided around the rotor chamber, a compression/power barrier and an exhaust/intake barrier. The combustion chamber has a non-reversing compression barrier and a compression hold barrier regulating the combustion of gas.
