1. An internal combustion rotary engine, comprising:
a non-rotating outer housing;
a pair of counterrotating rotors within the non-rotating outer housing;
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; and
in which compressed air and fuel from external to the outer housing are:
introduced into the outer housing and then into chambers formed by the structured inner surfaces of the rotors;
mixed and ignited to expand in volume, causing the rotors to move and the power shaft to rotate about the axis; and
exhausted from between the inner surfaces and then from within the outer housing.
