Claim 30:
31. A method of internally combusting gases within a rotary engine, comprising:
a) providing an internal combustion rotary engine which comprises a non-rotating outer housing, a pair of counterrotating rotors within the non-rotating outer housing, and a power shaft, having an axis, to which each of the rotors is coupled, one rotor coupled directly and the other rotor coupled through a reversing gear arrangement; in which each rotor has a structured inner surface perpendicular to the power shaft axis, and each inner surface counterrotates past the other;
b) introducing compressed air and fuel into the outer housing of the engine;
c) mixing the compressed air and the fuel together; and
d) igniting the mixed compressed air and the fuel within chambers formed by structured inner surfaces of the rotors, causing the rotors to move and the power shaft to rotate about the axis.
