Abstract

The utility model relates to the field of engineering and more particularly to engine design. A rotary internal combustion engine contains a cylindrical rotor (2) disposed in a cavity of a stator (1). Pistons (3) which are made, inter alia, from carbon composite materials travel in grooves (9) of said rotor which form an equilateral triangle inscribed in the circle of the rotor. The pistons are flat and have a thicker section in the head and are thinner at the rod. The rod likewise performs the function of a piston. The following are arranged in the stator symmetrically in four segments around the sides: a spark plug (5), an air injector (7), a fuel mixture injector (8), cooling openings (12), and an exhaust outlet (6) is located in the cavity. The technical result is that of simplifying the design, increasing engine speed, reducing vibration and noise, and improving engine efficiency.

Description

 ROTARY INTERNAL COMBUSTION ENGINE

FIELD OF TECHNOLOGY

 Field of technology of utility model: engine building

BACKGROUND OF THE INVENTION

 Known 4-stroke piston internal combustion engine (1), containing a cylinder, piston, connecting rod, crankshaft, intake and exhaust valves, spark plug, etc. The rotation of the crankshaft in it occurs due to the combustion of the fuel mixture in the cylinder between its bottom and a piston. The piston moves downward by rotating the crankshaft through the connecting rod. A full cycle takes place in two revolutions of the crankshaft (four cycles). The disadvantage of piston engines is the reciprocating movement of the pistons during operation, which limits the number of revolutions of the crankshaft, as well as the reliability of the system. Rotary engines are largely devoid of the disadvantages of piston engines. Their history began with the invention of the Wankel engine (1), which is a piston-rotor, in the form of a triangle, placed in the housing, where it makes a complex epicyclic motion with the help of a special eccentric. The working process is carried out in a four-cycle cycle due to the combustion of the fuel mixture in volumes limited by the inner surface of the housing and each side of the piston-rotor. The proposed design of the utility model is also a rotary engine, so the Wankel engine can be taken as an analog. Significant disadvantages of the Wankel engine are the problem of sealing the internal working volume of the engine and the low compression ratio of the fuel mixture.

 Known rotary engine Kuznetsov, RF patent N ° 2074967, class. F02B 53/00, published March 10, 1997, which contains a cylinder with exhaust and bypass valves, a piston with a connecting rod and crank mechanism, a stator with combustion chambers, candles and a nozzle for the release of burnt gases, a rotor with cavities placed in it, end caps. The rotation of the rotor is provided due to the energy of the gas flow of the burnt fuel-air mixture in the combustion chambers occurs alternately in one of them. The disadvantages of the prototype: a rigid connection of the piston system and the rotor limits the increase in the number of revolutions of the engine, reduces its mechanical reliability and, accordingly, reduces the efficiency.

 A PISTON MACHINE WITH A ROTATING CYLINDER is also known. Author TOIFL Erich, RF patent .Ns> 2293186, cl. F01B 13/06, F02B 75/26, published 02/10/2007. The machine comprises at least one block consisting of a cylinder and a piston, which is rotatably disposed in the rotor housing about its axis of rotation. In this case, torque is transmitted to the rotor housing, and the piston action line lies in a plane perpendicular to the axis of rotation of the rotor housing, and is directed eccentrically to the axis of rotation of the rotor housing, and passes in a straight line.

This invention will be chosen as a prototype for the proposed utility model. The disadvantages of the prototype.

 1. The rigid connection of the piston system and the rotor limits the increase

 the number of revolutions of the engine, reduces its mechanical reliability and, accordingly, reduces the efficiency.

 2. There is no forced cleaning of the combustion chamber from burnt gases, which

 reduces the amount of incoming fresh charge of the fuel mixture, therefore, less useful work will be obtained per cycle, and hence lower efficiency.

 The indicated purpose of the utility model is achieved by introducing into the design of the utility model pistons located directly in the rotor and nozzles of forced air supply (including oxygen).

 The proposed design of the utility model is a rotary circuit.

free piston internal combustion engine is shown in Figure 1.

The fixed part of the engine is the stator 1 in the form of a cylinder with a cavity 13 in which exhaust openings 6 are made (figure 2). The rotor 2 is fixed on the axis. In order to increase wear resistance, increase the number of engine revolutions, reduce mechanical losses due to the crank mechanism,

Freely moving pistons are placed directly in the rotor. To do this, grooves are made in the rotor - working chambers 9 (Figure 3) at an equidistant distance in the form of an equilateral triangle, along which three pistons 3 move. Pistons are flat, solid (or composite), have a thickening in the head and are thinner at the stem. The rod also performs the function of a piston. The piston may also be made of composite materials. This arrangement of the pistons allows the use of gas, including hydrogen, as a fuel mixture. In the stator, equally spaced, in 4 sectors there are a spark plug 5, an air supply nozzle (or oxygen, when using hydrogen as a fuel mixture) 7 and a fuel mixture (or hydrogen) 8, engine cooling holes 12, there are exhaust holes in the cavity 6.

 Spark plug 5-1 (Figure 1) is energized. There is a discharge and

ignition of the compressed fuel mixture in the combustion chamber 11-1. From the gas pressure, the piston 3-1 begins to move, transmitting a force impulse to the rotor 2 by compressing the air in the damping chamber 10-1 of the rotor 2. The rotor starts to rotate clockwise (Figure 4). At the same time, the exhaust opening 6 of the stator 1 opens, exhaust gases exit. At the same time, the piston 3-3 opens and, under the action of gas pressure, begins to move counterclockwise, compressing the fuel mixture received in the working chamber 9-3 in front of the porphy. At the same time, the fuel mixture located behind the piston rod 3-1 in the working chamber 9-1 begins to compress. Further, the rotor rotates a few degrees clockwise (Figure 5). The air nozzle 7-1 opens. In the remaining working chambers 9-1, 9-3, the fuel mixture is compressed. Further, the rotor rotates a few degrees clockwise (Figure 6). The exhaust opening 6 of the stator 1 is blocked. The air nozzle 7-1 is shut off. The fuel mixture injector 8-1 opens. The rotor turns further (Figure 7), the fuel mixture nozzle 8-1 is blocked, the pistons 3-2 and 3-3 are suitable for the combustion chamber 11-4 and the spark plug 5-4. Further, there is a discharge and ignition of the compressed fuel mixture in the combustion chamber 11-4. The piston 3-3 starts to move clockwise. The cycle repeats. The advantage of the design of the rotary engine is that it does not have “dead spots” characteristic of piston engines. The absence of conversion of one type of movement to another (for example, reciprocating into rotary) allows the engine to operate at high speeds not available to conventional piston engines, the high compression ratio of the fuel mixture makes the rotary engine presented more economical than the Wankel engine. All this increases the efficiency of the presented rotary engine.
