Abstract

An engine design of a rotating pistonless, non-reciprocating internal combustion engine having an engine block having a drive chamber formed in an interior combustion surface having a drive surface and a sloped transitionary portion, and a rotor rotatably supported within the engine block. The rotor having a radially extending disc portion having a plurality of rotor combustion chambers. Each of the rotor combustion chambers has a pyramidal-shaped volume having a driven surface and a sloped transitionary portion, wherein combustion pressure in the rotor combustion chamber and drive chamber is exerted upon the drive surface of the drive chamber and the driven surface of the rotor combustion chamber resulting in driven rotation of the rotor.
