A method of operating an internal combustion rotary engine having three volume variable subchambers progressively defined by a rotor rotating in a chamber and opposed crank plate faces where intake and exhaust crank plates are journaled in said chamber, said intake and exhaust crank plates being drivingly connected to said rotor, including successively in each one of said three subchambers in time-offset relation passing a fuel mixture from a supply through a rotating said intake crank plate to the respective one of said crank plate faces, intaking said fuel mixture into said rotor and thence into the corresponding one of said three subchambers from said respective one of said crank plate faces, compressing said fuel mixture in said respective one of said three subchambers, transferring the compressed fuel mixture past said rotor into a fuel lock open in each one of said three subchambers during fuel mixture compression, returning said compressed fuel mixture to said respective one of said three subchambers, igniting said compressed and transferred fuel mixture with a spark communicated to said respective one of said three subchambers through said rotor to drive said rotor and said intake and exhaust crank plates angularly, passing said fuel mixture combustion products through said rotor from said respective one of said three subchambers and thence through a rotating said exhaust crank plate via a respective one of said crank plate faces to a region beyond said chamber, and driving an output shaft with said intake and exhaust crank plates.
