A rotary device which can be an internal combustion engine, and methods, for receiving fluid input including fuel and air, and generating a fluid discharge. The rotary device includes a stationary outer housing, a rotatable cylinder housing, and a rotatable star-wheel, the star-wheel preferably having a central wheel body, and a plurality of radial arms extending outwardly from the star-wheel body, with pistons connected to the radial arms. The star-wheel, pistons, and cylinder housing are cooperatively designed and configured to rotate substantially in unison within the outer housing whereby the pistons move in reciprocating paths along axes of the cylinders, preferably defining variable angles of about 10 degrees to about 30 degrees, at the piston heads between the longitudinal axes of the cylinders and radians extending from the star-wheel axis of rotation to the head of the respective piston. The housing axis of rotation is preferably displaced from the star-wheel axis of rotation, and the magnitude of displacement between the axes preferably determines compression ratios in the cylinders. The rotary star-wheel preferably defines therein a central body portion and radial arms extending therefrom, the pistons being slidably connected to the radial arms, and received in the cylinders. |
