1. An internal combustion engine, comprising a pair of counterrotating rotors 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 shaped inner surface perpendicular to the power shaft axis, the shapes of both rotors defining at least one combustion chamber within which combustible gases are combusted and expand to counterrotate the rotors relative to each other to rotate the power shaft around the power shaft axis.
