ABSTRACT:
A rotary internal combustion engine includes a block having a generally elliptically shaped bore and a substantially round rotor adapted to rotate on a straight shaft in the bore of the block. The rotor is provided with a pair of substantially diametrically mounted rotor segments, the rotor being provided with a pair of recesses for receiving the rotor segments and the rotor segments being pivotally mounted to the rotor such that a portion of each rotor segment tends to be forced outwardly by centrifugal force upon the rotation of the rotor. The block is provided with a charging and a combustion space formed in the space between the elliptical shaped bore and the round rotor. The combustion chamber is enlarged by the outward movement of an outer segment pivotally mounted on the block. A pair of vanes between the rotor segments are mounted in slots on the rotor for the forming of a seal between the rotor and the inner surface of the bore of the block. The engine may be operated on any type of gaseous fuel. The narrowing of the space between the round rotor and elliptically shaped bore functions to compress the air/fuel mixture enclosed between the vane and the rotor segment. The engine provides two combustions per revolution. Larger engines may be constructed coupling any number of rotors and blocks either in line or side by side with the rotors coupled together. A variable displacement engine is provided by varying the size of the combustion chamber by limiting the outward movement of the outer segment.
