<p>A rotary engine having an outer rotor (50, 52, 54) on outer rotor bearings (62, 64) and an inner rotor (30) within the outer rotor mounted on inner rotor bearings (34, 36) the outer rotor axis being offset relative to the inner rotor axis, a housing (12, 14) enclosing the inner and outer rotors, generally radial arms (38) formed on the inner rotor, and recesses (44) defined between them, inwardly projecting lobes (66) defined by the outer rotor, spaced apart, and defining outer rotor chambers (76), the inner rotor arms extending into the outer rotor chambers, at least around a portion of the rotational path of the rotors, a fresh air intake port (88) for inducting fresh air into the outer rotor chambers in sequence at a predetermined point in the rotational path of the outer rotor, a fuel/air intake port (90) for inducting burning fuel/air into the outer rotor chambers in sequence at a second predetermined point, and an exhaust port (86) for exhausting gases from the outer rotor chambers in sequence at a third predetermined point. The invention also relates to a method of converting fuel energy into rotary force by a rotary engine.</p> |
