DESCRIPTION OF THE INVENTION
The invention relates to engine building, namely to internal combustion engines. The engine is designed for use in all types of land and water transport, light aircraft and stationary power plants.
From the patent literature [SU, Inventor's Certificate 1451304 A1, cl. F 02 B 53/00, 1989 g.] known internal combustion engine, comprising a housing with the exhaust manifold round the rotor, along the perimeter of radial slots set in the working plate, which is accepted as the closest analogue to the proposed invention.
The object of the invention is:
use a logical, not a controversial general principle of construction and operation of the engine;
to create an engine that has no parts, reciprocating movements and rigidly connected to the working body;
to achieve a high torque over a wide engine speed range, to manage the duration of the suction stroke and the stroke to the extent necessary;
in order to improve efficiency to ensure the presence of a node changes of engine capacity at partial loads to the extent necessary, without changing the compression ratio;
in order to improve filling of the cavities of working the fresh fuel-air mixture to use an inner surface of the working organ of the rotor as a centrifugal blower. Thus providing additional cooling and a constant supply of fresh lubricant contained in the fuel, to the bearing assembly, the rotor and the working plates.
to ensure optimal combustion process of the working mixture and thus reduce the toxicity of exhaust gases, to provide the necessary expansion of the trajectory of combustion products during cycles stroke and exhaust flowing in the active catalyst medium.
in order to improve efficiency and the ratio of power / weight, to provide four full cycle - intake, compression, power stroke and an outlet for one revolution of the shaft with minimum dimensions and weight of the engine;
maximize simple construction with a small number of parts and ease of manufacture and assembly and the motor;
Technical result is achieved due to the fact that the proposed rotary internal combustion engine comprises a housing with the exhaust manifold round the rotor, in which the perimeter of radial grooves established working plate, wherein the motor is provided with a gear reducer assembly changes the displacement volume and the front cover, which is formed intake manifold and set the length of the plate dampers adjusting mechanism of absorption and release phases. The motor housing comprises first and second hemispheres, wherein the body-side surface of the second hemisphere including the exhaust manifold, the catalyst layer is coated. In the cavity of the rotor guide sleeve assembly installed changing the engine capacity, which is communicated with an opening for feeding mixture, formed in the lid and rotor cavity communicated with the suction manifold, which in turn communicates with a first hemisphere of the housing.
In the considered design no crank and piston gas distribution mechanism. A working body, the rotor has a circular shape and uniformly rotates around an axis, thus achieving a good balance of all of the unit. Moreover, the torque on the shaft is created by the application of energy of expanding gases to the working plates arranged in radial grooves on the rotor perimeter. Due to what the applied force is directed tangentially to the rotor, and the force is applied consistently over his shoulder radius. The internal surface of the rotor is used as a centrifugal blower mixture, whereby the overpressure reached the suction, and a supply of additional cooling and lubrication to the working plates, the rotor and the bearing assembly.
Due to the absence in the engine timing, use of the rotor as a centrifugal compressor, and a constant presence in the suction phase of several working cavities completely eliminated harmful pulsation flow of the fuel mixture. And due to the redundancy of the suction pressure, the possibility of regulating the duration of the cycle to the extent necessary, obtain a stable high filling indicators, and therefore, torque and power over the operating range of the engine speed.

Viewed engine consists of three main parts.
1. The housing / 1 / with the working chamber and the exhaust manifold / 2 /.
2. Rotor / 3 / from the platen / 4 /.
3. The front cover of the engine / 5 / in which the intake manifold is made / 6 / and the set plate dampers suction mechanism for regulating the duration of the phases / 7 / and release / 8 /. Dampers, providing change the length of the intake stroke and exhaust are a certain shape of the plate fixed to the axles and 8.1 /7.1 /. Dampers / 7 / and / 8 / through its axis and /7.1/ /8.1/ actuated control mechanisms, analyzes engine speed, load and other parameters. Gate / 7 / is located in a special cavity in the inner surface of the front cover / 5 /, which allows it to be on the front plane of the connector cover - body, actually between the side surface of the rotor and the front cover. Relatively moving the shaft center /7.1/ / oscillates with small amplitude / gate alters the effective length of the suction manifold / 6 / in its end portion, thereby adjusting the angle of the intake stroke duration. Schieber / 8 / has a similar structure, similar to the principle of accommodation and activities. Its difference is that the plate has a T-shaped / due to the fact that the exhaust manifold / 2 / is situated in the vertical plane of the upper part of the body / 1 //. Moreover, its upper folded at 90 o working part has a curvature radius R1, measured from the center axis and /8.1/ curvature equal to the inner surface of casing / 1 / to the point where it starts the exhaust manifold / 2 /, which forms a starting edge and its movement adjusts damper / 8 /.
Node change of engine capacity includes details / 9, 10, 11 /.
The body is the main and largest part of the engine. Its oval in shape due to the internal working cavity formed by the two hemispheres that form the engine operating cycles.
Hemispherical shape may be different and depends on the characteristics to be obtained from each individual engine.
The second hemisphere in which the bars are stroke and release smoothly into the exhaust manifold, and is part of the body.
Suction combustible mixture occurs in the first hemisphere and through the intake manifold, made in the engine front cover. In front of the motor housing - in the working chamber is a working body, a rotor with radially extending operating plate. At the rear of the housing for the rotor is a single-stage gear reducer - gear / 12, 15 /, allowing during operation to continuously transmit the primary torque flux in the motor output shaft / 14 / regardless of the vertical movement of the rotor and rotor shaft / 13 / for changing the displacement volume motor. Thus the working volume of the engine increases when the drive gear / 12 / is located on the axis of the rotor / 13 /, moves clockwise along a path having a radius R, equal to the distance between the rotor shaft and the output shaft of the motor / 14 / obkatyvaya driven gear / 15 / disposed on the output shaft of the motor on its pitch circle diameter /fig.3/. The corresponding movement trajectory sets the unit change in the working volume of the engine, the lateral sides of adjacent sleeves / 9 and 10 / which are treated with appropriate curvature radii.
The same device, with the appropriate selection of the diameter gear reducer can withstand constant compression ratio when changing the capacity of the engine. Since for moving the axis of the driving gear clockwise from the position corresponding to the minimum working volume / for coincidence of the horizontal axis gear / 12 / and / 15 / /, to the maximum, the trajectory of radius R, it does not only vertical but also horizontal movement , thereby increasing the volume of the combustion chamber at the time of maximum compression.
Engine main working body - the rotor has a circular shape and uniformly rotating around its axis, thereby achieving a good balance of the engine. Said rotor having a relatively large diameter, not only used as a working body and a centrifugal blower and partly serves the function of the flywheel.
Suction, compression mixture, stroke, and the exhaust occurs through obkatyvanii working plates arranged radially in the rotor, the inner surfaces of hemispheres working chamber.
The first hemisphere flow suction stroke and the compression of the working mixture. In this fuel mixture is fed through a hole in the front cover /5.1/ and enters the cavity of the guide sleeve / 11 /, is sucked from the rotating rotor, simultaneously cooling and lubricating the bearing assembly, the working plate and the rotor itself. Only then is injected at a pressure in the intake manifold.
After passing the compressed combustible mixture by the spark plugs / 16 / there is risk of fire, and then in the second hemisphere - the extension stroke and release. To provide better ignition of compressed mixture, and optimal flow and the combustion process and to obtain minimum emissions performance, the entire surface of the second hemisphere including the exhaust manifold, the catalyst layer is coated. Thus, the entire combustion process takes place in the environment of the active catalyst. The energy of the expanding gases acts on the platen, creating therethrough torque applied to the rotor. After passing through the plate leading edge of the exhaust manifold, formed by a special slide valve regulating the beginning of the exhaust stroke, exhaust gases begin to break through the exhaust manifold zone thus continuing to influence the operating plate to the end of the exhaust stroke, but the principle of the gas turbine engine.
The front cover is more difficult and at the same time the carrier part of the engine. It is located inlet, intake manifold, dampers duration of the mechanism of regulation of suction and discharge cycles, and the assembly and change of engine capacity. The front part of the rotor shaft / 13 / is located in the bearing assembly, provides a bearing element of the rotor and transmits the torque only to the accessory drive / pump, alternator, mounted on the outside of the front cover / and rotates in two ball bearings / 17 / located in the mobile sleeve / 9 / unit change of engine capacity. The movable sleeve / 9 /, in turn, by means of two eccentrics / 10 / with the bearing assembly, the shaft and the rotor can move within certain limits inside the guide sleeve / 11 /, thus changing within predetermined limits the volume to be filled with fresh fuel mixture / changing working engine size /. At the assembly of engine capacity changes the whole structure forms a common and compact: the front cover - the rotor. To ensure the necessary compression and separation of workers and the rotor segments are in different working cycles, you need a reliable seal between them, provides a working plate specially shaped.
The main sealing force is generated by the centrifugal force acting on the plate and occurring when the rotor rotates with the operating speed. When the rotor rotates at a speed that does not guarantee the establishment of the necessary centrifugal force, such as when the engine is started, the required sealing force is a flat spiral spring, repeating the trajectory of movement of workers and the plates inserted into the rotor. At the same time to prevent from turning one end of the spring fixed to the front cover, and the second is free. Due to this spring is always in working order and are gradually moving apart, it compensates for wear of the plates.
