FIELD: engine manufacture. SUBSTANCE: internal combustion engine has body mounted for rotation and coupled fast to output shaft. Body includes chambers of variable volume with pistons placed in them and interconnected and discharge valves. Chambers communicate with atmosphere through nozzles. Chambers are connected by pairs to nozzle corresponding to given pair and oriented in opposition. Pistons are manufactured two-way and are rigidly intercoupled. Discharge valves are fabricated in the form of rotary control valves with centers of gravity displaced with reference to their axis and with two cylindrical parts which cylindrical surfaces are made with unequal radii.
