An engine of the internal combustion type having a plurality of cooperating adjacent parallel rotors of elliptical cross section having hollow interior flow passages communicating thru hollow supporting shafts forming a combustion chamber having a varying volume which depends upon the rotational position of the rotors. Each rotor has a second flow passage opening thru its interior surface communicating thru to slots at one apex of its major axis so as to provide valving for the combustion changer.
