Abstract: A rotary internal combustion engine that has a housing, main rotors with an external cylindrical surface with rigidly fixed gear wheels and blades in the form of gear ledges (protrusions), as well as additional rotors with an external cylindrical surface with rigidly fixed gear wheels and recesses corresponding to the size of the blades on the main rotors. Additionally, the engine includes a unit for preparing and igniting the working mixture and a unit for discharging exhaust gases. Moreover, the circumference values of the main and additional rotors do not match, and are multiples of the length L1 between the nearest points of tangency (physical contact) of the center of the surface of the gear ledge with the housing.
