ABSTRACT OF THE DISCLOSURE A pair of sealed engine rotors are connected by links and cranks to a single shaft for simultaneous operation one-quarter turn out of phase. The use of internal gears and eccentrics for driving the two rotors is avoided. The expanding charge in the chamber containing the second rotor is diverted back into the chamber for the first rotor whereby this charge may further expand and assist in driving the first stage rotor. The rotor chamber profiles are free of abrupt humps, thus avoiding seal shock and wear and chatter marks on chamber surfaces. Vaporized fuel is utilized to cool the engine by passage through the centers of the rotors. Increased compression, greater rotor speed and more usable power are fully-achieved features.
