FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, in particular to rotary-piston internal combustion engines operating on a two-stroke cycle; it can be used in various industries. An engine is proposed, consisting of a stator case with a cylindrical cavity, in which a rotor is eccentrically installed, in which longitudinal cylindrical grooves are formed, symmetrically arranged along the angle of rotation, forming working and non-working edges, and in the latter, semi-cylindrical grooves are formed, forming combustion chambers together with working chambers. Elastic elements and displacement pistons are non-pivotally installed in grooves, ribs of which constantly interact with a cavity wall, and inner cylindrical surfaces come into contact with working edges of the rotor, forming a working chamber and two compression chambers. A system for the intake of a fuel-air mixture and the exhaust of exhaust gases is made in the form of an intake and exhaust channels in the stator case, where a spark plug is also installed. When the semi-cylindrical groove is combined with the spark plug, the fuel-air mixture ignites, the pressure in the working chamber increases, the displacement piston acts on the working edge of the rotor, and the resulting torque leads to rotation of the rotor. When edges of displacement pistons are combined with edges of the exhaust and intake channels, exhaust gases are released and the “fresh” fuel-air mixture is taken, respectively. Then, the working chamber begins to act as a compression chamber, in which the fuel-air mixture is compressed and the described cycle is repeated. Three working two-stroke cycles occur during one rotation of the rotor.

EFFECT: hydraulic machine designed for use as a two-stroke rotary-piston internal combustion engine.
