PURPOSE:To enhance the output power of an engine, by juxtaposing a first auxiliary cylindrical rotor, a main cylindrical rotor and a second auxiliary cylindrical rotor in contact with each other, and noneccentrically rotating the main rotor to reduce an energy loss. CONSTITUTION:In an internal-combustion engine 1, a main cylindrical rotor 2 and a first and a second auxiliary cylindrical rotors 3, 4 are rotatably supported in contact with each other in a housing 17. The auxiliary rotors 3, 4 have recesses 3b, 4b, into which a rotor body 6 provided on the main rotor 2 to divide a main rotation chamber 10 is moved. An intake port 8 and an exhaust port 9 are provided for a rotation chamber 7 in which the second auxiliary rotor 4 is housed. A mixture in a working chamber 13 is ignited and burned by a spark plug 25 so that the rotor body 6 receives the explosion pressure of the mixture to rotate the main rotor 2. |
