ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F02B53/08 F01C1/356 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed rotary internal combustion engine consists of cylindrical stator divided into cross working zones with internal working surface in form of regular circumference, compression plates radially spring-loaded in stator, and rotors arranged concentrically on one shaft in working zones. Engine has two working zones and two rotors, first one with three working projections, and second one also with three working projections but differing on configuration from first one, working zones of stator are divided, each, into three sections through 120 degrees. Engine has first working zone in stator of which three compression plates, three compression chambers, three air suction ports, three electromagnetic nozzles of first circuit and three places of connection of electromagnetic nozzles of second circuit are found. Engine has also second working zone in stator of which three compression plates, three combustion chamber, three electromagnetic nozzles of second circuit, three igniters, three displacement chambers of working stroke of designed value and three combustion products discharge ports are found. Stator of second working zone is displaced relative to first one. Engine is provided with rotor of second working zone with three working projections providing timely closing of combustion chambers, compression of working mixture and its ignition. Processes of suction, preparation of working mixture, compression and delivery take place in separate working zone, and processes of ignition of fuel mixture, working stroke and exhaust take place in other working zone. Combustion chambers arranged in stator housing are igniter part of volume of working stroke and are not separated from the volume. Engine has two circuits of electromagnetic nozzles, 6 pcs. First circuit of electromagnetic nozzles, 3 pcs, provides delivery of fuel into compression space for preparation of working mixture, and second circuit of electromagnetic nozzles, 3 pcs, provides delivery of working mixture into combustion chambers. Electromagnetic nozzles of second circuit are adjusted for operation with delay of injection of working mixture into combustion chamber after its closing by working projection of rotor of second working zone.

EFFECT: increased efficiency of operation, simplified design and improved operation of rotary engines.
