ABSTRACT:
A rotatably alternating air or water cooled two-stroke internal combustion engine comprising a cylindrical casing, and a rotor comprising two radially extending vanes affixed to a shaft rotatably mounted within the casing upon two end plates. Two longitudinally extending walls affixed to the casing. Sealing strips provided between said walls, the shaft, the vanes, the casing and the end plates respectively. Working and supercharging interior chambers between the vanes and the walls. The casing and/or the end plates equipped with ports which communicate with the interior chambers, allowing for intake of combustible air-fuel mixture and exhaust thereafter. Ignition means delivering a spark at the end of each working cycle. An extendable and adjustable connecting rod assembly converting the oscillating bi-directional rotary motion of the output shaft into a continuous unidirectional motion of the main shaft. A self lubricating mechanism incorporated into the engine.
