FIELD: engines and pumps. ^ SUBSTANCE: invention is related to internal combustion engines with uneven motion of working elements in working annular chamber. Multisectional rotary-vane engine comprises sections of two-stroke engines, every of which consists of annular working chamber, spark plug, two vane rotors arranged with the possibility of rotation relative to engine central axis, inlet and outlet valves and mechanism for periodical change of vane rotors speed, comprising crankshaft, axle of which has slider fixed to it, which slides along guide fixed on guide shaft. Vane rotors are arranged on bushings and/or disks, and every of them is rigidly fixed to crankshaft installed at section end. Guide shafts are connected to external shaft common for section vane rotors via gear transmission. Rotation axis of guide vanes is located between two opposite points on circle circumscribed with crankshaft axle, and is displaced from engine central axis, and crankshafts are in antiphase to each other. ^ EFFECT: increase of mechanism gears wear resistance, reduction of sluggishness in components that rotate with alternating acceleration, increase of engine operation resource, increase of engine capacity, reduction of body vibration resultant from vane rotors acceleration. ^ 5 cl, 4 dwg |
