A combustion engine comprised of (i) at least one compression stage, (ii) at least one combustion unit, and (iii) at least one expansion stage is described. The compression and expansion stages include tongue and groove cylindrical rotors in sealing relation to one another for fluid volume displacement and transfer of rotational force from expansion of compressed fluid volumes following combustion. Related methods of providing a rotational force to a drive shaft are also described.
