Abstract
A rotary internal combustion engine comprises a cylindrical casing and a cylindrical rotor. Several stepped crankshafts rotatably connected to the rotor pass through the ends of the casing, thereby confining motion of the rotor to orbital motion. Radial vanes extend from an axial shaft in the casing to the inner surface of the casing wall and form seals against the casing. Combustion chambers are formed between adjacent vanes. Intake, exhaust, and ignition systems provide a combustion cycle for each chamber as the rotor orbits.
