This invention relates to the field of internal combustion engines and compressors in general and to linear compressors, in particular these used as in U.S. Pat. No. 8,056,527, by accurately controlling the pressure being delivered into the combustion chambers of said engine while returning unused energy of the compression phase into the motor for complete expansion.

Another improvement relates to a pressure compensated vane to be used inside grooves of the motor assembly rotor. This invention enables the vane to seal against the cavity of the housing tightly with minimal force.

This invention of a continuous motion revolving piston engine describes a machine comprising piston(s) fitted to rings that revolve around a stator circular base which has a cavity in which a disc fits to create a closed combustion compartment together with the casing. The disc has a disc cavity to allow the piston to pass. The rotation of the disc and piston are synchronized to allow the piston to pass through the disc cavity. As there are no reciprocating parts and optionally enables an oil free operation, it is more efficient and has cleaner exhaust than existing engines.

A composite intake system and method of operating a rotary engine with variable intake manifold is provided. The system includes two switching valves in a secondary intake switching tube to change the intake method. When the rotary engine works under low speed conditions, it adopts the long intake manifold and the side-intake mode. When the rotary engine works under medium and high speed conditions, it uses the short intake manifold and the composite-intake mode. When the rotary engine works under ultra high speed conditions, it takes the short intake manifold and the peripheral-intake mode.

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.
