Abstract:
1. A rotary engine including: a rotatable member; two or more cylinders spaced circumferentially of said rotatable member, respective longitudinal axes of said two or more cylinders being located adjacent an outer region of said rotatable member and extending tangentially to a rotational path thereof; and, two or more pistons, each piston being associated with a respective cylinder, each said piston being associated with a respective piston lever pivoted on said rotatable member at a fulcrum point eccentrically to a rotational axis of said rotatable member and wherein movement of each said piston between top and bottom dead centres is controlled such that combustion energy is transmitted to said rotatable member by said two or more cylinders moving away from said respective two or more pistons, said engine characterized in that movement of each said piston is controlled by a piston controller disposed adjacent a proximal end of a respective piston lever, the proximal end of each said piston lever being coupled with said piston controller to communicate movement to a respective piston lever; said controller comprising a link arm pivotally coupled at opposite ends thereof to proximal ends of piston levers of respective pistons of diametrically opposed cylinders whereby the excursion of one piston on a compression stroke is assisted by excursion of a diametrically opposed piston on a combustion stroke.
