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.
Claims20
An internal combustion engine, comprising:
- a housing having a central bore for a rotor and apertures for air intake, fuel delivery, and exhaust;
- a front cover having a fixed sun gear, a central bearing bore, and rigidly secured to said housing;
- a rear cover having a central bearing bore, and rigidly secured to said housing;
- a rotor having 2 or more pair of intermeshed synchronously geared crankshafts arranged such that their proximal axes are constrained to rotate equidistant about the central axis of said rotor and such that their distal ends rotate in an epicycle;
- wherein one in each pair of geared crankshafts has an extended proximal end configured to accept a timing gear, and wherein each said timing gear meshes with said fixed sun gear;
- a plurality of cylinder bores in said rotor, each with a piston and connecting rod operably connected to each said crankshaft distal end;
- an output shaft operably engaged with said rotor.
