Abstract: An arc turbine system includes an elliptical housing, a rotor having two sliding channels positioned centrically to the housing, and two sliding arcs disposed within the rotor sliding channels and slide therein. The sliding arcs are engaging the housing simultaneously at both ends in a near friction-free environment supported by repulsion force of like-pole magnets. Four chambers disposed within two static chambers between the rotor and the long-axis of said housing, the two static chambers further include proper inlet and outlet ports configured to allow fluid and gas flow into and flow out of the static chambers. The system configured in two distinct settings for two distinct uses.

Abstract: A Turbocombustion engine for conversation of combustible fuel to rotating energy includes a cylinder, piston, connecting rod and crankshaft system for suction and compression and a rotor for expansion and exhaust. Combustible fuel is compressed within a combustion chamber separate from the cylinder and the combustion force applied directly to the rim of the rotor as in turbines with much larger capacity than the cylinder, converting the entire combustion force at maximum torque to rotating energy. The combustion chamber also includes a variable compression ratio system that constantly adjusts the compression ratio within the combustion chamber for optimum performance of the engine under all variables.
