ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: rotary internal combustion engine has stationary housing with working chamber provided with dominating cylindrical surface with shaped projection. Cylindrical rotor installed on output shaft partially interacts with shaped projection. Cutoff is mounted on rotor. Combustion chamber and exhaust port are made in housing. Surface of projection engaging with rotor is made cylindrical, mating with surface of rotor, and it is arranged direct before combustion chamber.
