FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: invention relates to internal combustion piston engines with rotary working members, and it can be used in power engineering industry, as hydraulic motor, pump and internal combustion engine in watercraft and road vehicles. According to proposed invention, engine has housing with nozzles, intake and exhaust ports and rotor with sliders fitted in its slots and hinge-connected with pistons. Working surface of housing is formed by movement of center of part of circumference along guide contour consisting of two aemicircumferences conjugated by parallel straight lines forming toroidal cylindrical surface, or in form of surface formed by movement of center of part of circumference along guide0ellipse, or in form of surface formed by movement of center of part of circumference along guide - cassinian oval at where a is constant value; c is distance from center of Cassinian oval to its foci. According to invention, chamber to prepare fuel for self-ignition is made in housing at butts of compression and expansions sectors, and combustion chamber is made on toroidal surface of rotor in each working chamber. ^ EFFECT: improved specific mass-dimensional characteristics and economy of engine.
