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 into three cross working zones with internal working surface of in form of regular circumference, compression plates radially spring-loaded and arranged in stator and three rotors arranged concentrically on one shaft in working zones. Two extreme rotors are of similar shape, being provided with two working projections, and middle rotor is provided with four working projections. Extreme working zones of stator are identical, being displaced through 90 degrees relative to each other. Each zone is divided into two sections through 180 degrees by spring-loaded compression plates. Middle working zone of stator is divided by spring-loaded compression plates into four equal compression section through 90 degrees. Engine has one middle working zones in stator of which four compression plates, four compression chambers, four air suction ports, four electromagnetic nozzles of first circuit and four places of connection of electromagnetic nozzles of second circuit are found. Engine has two extreme working zone in stator of each of said zones two compression plates, two combustion chamber, two electromagnetic nozzles of second circuit two igniters, two displacement chambers of working stroke of designed value, two combustion products discharge ports are found. Processes of suction, preparation of working mixture, compression and delivery take place in separate middle working zone, and processes of ignition of working mixture, working stroke and exhaust take place in two extreme working zones. Combustion chambers arranged in stator housing are integral part of volume of working stroke and are not separated from the latter. Engine contains two circuits of electromagnetic nozzles, 8 pcs. First circuit of electromagnetic nozzles, 4 pcs, provides of fuel into compression space where working mixture is prepared. Second circuit of electromagnetic nozzles, 4 pcs, provides delivery of working mixture into combustion chambers. Electromagnetic nozzles of first circuit provide two modes of delivery of fuel, first one through 180 degrees of turning of working shaft, and second one, through 90 degrees of turning of working shaft. 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 extreme working zone. Engine has two functional modes, namely, conventional and higher-powered ones, with possibility of changing over from one into the other in operation. Under conventional operating mode, scavenging of combustion chamber is provided simultaneously with working stroke, and working stroke of rotors of extreme working zones is increased owing to delivery of minimum amount of remaining working mixture.

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