Abstract
A rotary internal combustion engine includes a housing, a front cover, a rear cover, and a rotor. The rotor contains 2 or more pair of radially arranged, synchronously geared, crank shafts. The main journal of every other crankshaft has a timing gear at one end and a drive gear at the other. The timing gears mesh with a stationary sun gear fixed to the front cover. The rotor contains radial cylinder bores, each with a piston and connecting rod operably connected to each crankshaft. An output shaft with a sun gear pierces the center of the rotor and meshes with the drive gears. The rotor revolves around the output shaft within the housing which contains ports for intake, fuel delivery, spark, and exhaust. The crankshafts rotate at twice the rate of the rotor, thus producing four piston strokes per revolution of the rotor.
