Disclosed is a rotary engine, comprising a stator and a rotor rotatably connected thereto. A stator holder with an annular recessed variable track guide groove is on each end of the stator. A sidewall, close to the rotor, of the stator is provided with an arc-shaped combustible gas groove, a combustible gas inlet, a ring-shape groove, a combustion chamber, a decompression device and an exhaust gas outlet. A compression-resistant element is provided in the ring-shape groove. The rotor is provided with a combustible gas piston chamber having a combustible gas piston, a slider slot having slider, and gas exchange channels. The sliders on the same generating line on the rotor and the combustible gas piston are connected fixedly to the same sliding rod in a sliding rod groove, and the two ends of the sliding rod extend into the annular recessed variable track guide groove of the corresponding stator holder.

A motor is configured to apply a rotational force to a wheel that includes a rim rotatably mounted to an axle about a first axis. The motor has a rotor coupled to the rim. The rotor has an interior cavity and a plurality of radial slots formed therein. A cylindrical stator is disposed within the cavity and has a second axis offset from the first axis. The stator is fixed in rotation relative to the axle. The motor further includes a plurality of vanes, each vane being slidably disposed within one of the plurality of radial slots. A compressed gas source is in fluid communication with the cavity and selectively provides compressed gas to the cavity to rotate the rotor.

An internal-combustion engine includes an engine housing having an interior space with an inner wall, which section-wise corresponds to a segment of a circular cylinder and a segment deviated from the circular cylinder, wherein a rotary disc is centrally rotatably mounted in the interior space around an axis, and an intake area, a compression area, an ignition area, a working area and an exhaust area are formed, wherein the rotary disc is a circular cylinder with two slots in the circumferential area, into each of which slots a sliding element is inserted, wherein each sliding element movable along the slot, and is moved along the slot on rotation of the rotary disc.
