Abstract
Star Engine is a four stroke internal combustion engine, which converts the eccentric motion of the center of the rotor directly to a rotary motion of a main shaft. This engine is formed by the principle a small circle rolling inside a larger one (FIG. 1). The star shape of both the rotor and stator are formed by the ratio between them (FIG. 2).
Claims15
A twin rotor star engine comprising:
- an eccentric shaft rotating about a central axis of the engine wherein its front main journal is mounted on a front rotor cover and its rear main journal is mounted on a rear rotor cover;
- a pair of front and rear rotors driven eccentricly by the eccentric motion of the eccentric shaft;
- a pair of front and rear stators housing for the front and rear rotor;
- an intermediate rotor cover attached to the front and rear stator housing for the back of the front rotor and the back of the rear rotor;
- a pair of balance weights attached to the front and the rear ends of the eccentric shaft balancing the rotation of the shaft;
- a pair of planetary gearsets mounted to the front and rear rotor cover housing for the eccentric shaft front and rear main journals;
- a pair of ring gears attached to the balance weights driving the planetary gearsets;
- a pair of rotor ring gears attached to the front of the front rotor and the front of the rear rotor rotating the rotors eccentrically and driven by a pair of sun gears;
- six sets of removable intake and exhaust valves, wherein each two sets of valves are driven by a camshaft mounted above them;
- a set of three camchain sprockets attached on the front end of each camshaft and linked to a eccentric shaft chain sprocket with a chain;
