Invention herewith described refers to the rotary four-cycle engine consisting of a cylindrical chamber (1) in the figure ‘’8’’ shape, single-wing rotors (2 and 3) with face surfaces in the shape of a mathematically defined curve that allow the rotors to bypass at a very close distance while the synchronous cinematic bond is realized through the shafts (6 and 7) containing a gearset (5) outside the chamber (1). The compression-expansion chamber (4) is located on the lateral face of the chamber (1), whereto it is attached by openings (10 and 11). Suction is performed through the opening (8), and exhaustion is performed through the opening (9).During the rotation of the rotors (2 and 3), for one revolution, varying capacities of four-stroke cycle are formed: suction, compression, expansion and exhaust.By mounting in series of one or more rotating blocks on the exhaust opening of the above mentioned engine, there is obtained multiple expansion rotary engine, which consequently leads to a significantly higher degree of transforming fuel energy into a mechanical operation.
