<p>A rotary internal combustion engine includes a block (10) having a generally elliptically shaped bore and a substantially round rotor (12) 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 (50, 60), the rotor being provided with a pair of recesses (54, 64) for receiving the rotor segments and the rotor segments being pivotally mounted to the rotor. The block is provided with a charging and a combustion space (28) formed in the space between the elliptical shaped bore and the round rotor. The combustion chamber (44) is enlarged by the outward movement of an outer segment (32) pivotally mounted on the block. The engine provides two combustions per revolution. A variable displacement engine is provided by varying the size of the combustion chamber by limiting the outward movement of the outer segment.</p> |
