Description

The invention relates to the field of transport engineering.

The disadvantages of such an engine are low specific power on the shaft, complex design and manufacturing technology.

The prior art rotary internal combustion engine containing a cylinder made in the form of a hollow torus of rectangular cross section, in the cavity of which there are shaped piston vanes, spring-loaded valves with seals, dividing the cylinder into sections, one end of which is fixed in the cylinder pocket, and the other is made resting on the piston blades and interacting with the metering valve and spark plugs located in the cylinder pocket, a shaft mounted in the bearing assemblies of the side walls, pressure belt, compress p and an exhaust manifold (see GB 2169964 A, 07/23/1986, F01C 1/46). This engine is adopted as the closest analogue (prototype).

This engine has not solved such tasks as sealing and lubricating the rubbing surfaces of rotor parts, namely the pressure belt, piston blades, dampers, rubbing against the wall of the engine housing, and the effective change of atmosphere in the working sections, since the rotor operates in turbine mode.

The objective of the invention is to remedy the above disadvantages.

To solve the problem, a rotary internal combustion engine containing a cylinder made in the form of a hollow torus of rectangular cross section, in the cavity of which there are shaped piston vanes, spring-loaded valves with seals, dividing the cylinder into sections, one end of which is fixed in the cylinder pocket, the other is based on piston blades and interacting with the metering valve and spark plugs located in the cylinder pocket, a shaft installed in the bearing assemblies of the side walls, pressurized belt, comp the quarrel and the exhaust manifold, according to the invention, the engine is equipped with an ejector, connected at right angles to the exhaust manifold and communicated with the compressor, and the piston vanes are fixed in the transverse grooves of the containment belt, rigidly fixed to the compressor disk, passing through the slit of the inner wall of the cylinder and fixed by a hub on the shaft at the same time, the pressure girdle is equipped with annular grooves in which graphite segments of compression rings are placed, and flaps along the perimeter are equipped with rectangular grooves in which parallelepiped-shaped graphite seals are placed, the seals being mounted on elastic plates made of heat-resistant steel.

Graphite seals mounted on elastic plates provide sealing of the working sections and lubrication of rubbing pairs in the engine. A compressor with a fuel supply manifold creates a “pressurization” of the fuel mixture in the working sections of the engine, and an ejector with a gas removal manifold powered by the compressor creates a vacuum and thus forms a direct-flow circuit that increases engine efficiency.

Figure 1 shows a rotary internal combustion engine.

Figure 2 shows a section aa in figure 1.

Figure 3 shows a section bB in figure 1.

Figure 4 shows the node I in figure 2.

The rotary internal combustion engine has a connecting belt 1 to which side walls 2 and 3 are attached. The side wall 3 is provided with an e-window. Between the walls 2 and 3 there is a compressor disk 4, which is rigidly connected to the pressure girdle 5, equipped with figured piston blades I-II-III, equipped with protrusions 20 included in the grooves "to" of the pressure girdle (dovetail type). The compressor disk with the hub is fixedly mounted on the shaft 6, which is located in the bearing assemblies 14 and is equipped with an impeller 23. In the pocket "a" of the connecting belt there is a shutter 11, rigidly connected to the roller 12, equipped with a spring 13 (torsion), the spark plug 16 (with elastic electrode), while the length of the valve should be greater than the height "N" between the inner wall of the cylinder of large diameter and the surface of the containment zone.

The side wall 2 is equipped with a pipe “b”, to which a carburetor 7 is connected, connected to the fuel supply manifold 9, connected to the metering valves 15. In the side wall 3 there are windows “e”, to which the exhaust manifold is connected 10. The side wall of the compressor 3 is provided a nozzle "d" equipped with an ejector 8, to which the exhaust manifold 10 is connected at right angles.

The damper 11 is provided with grooves with graphite gaskets 21 placed on elastic plates 22 made of heat-resistant steel.

Figure 4 shows the conjugation of the pressure belt 5, equipped with granite segments 19 on the elastic segments 24.

Engine operation

In a static position, the engine is shown in figure 1, which shows the position of the piston blades I-II-III and the position of the shutters 11 relative to the pockets "a", valves - dispensers 15 and spark plugs 16.

In dynamics, the operation of the engine is as follows,

When the compressor disk 4 rotates, the air enters the carburettor 7 through the nozzle “c” under excess pressure. The mixture enriched with fuel through the fuel supply manifold 9 enters the metering valve 15. The shutter 11 presses the valve stem — the metering unit 15, the fuel mixture is “injected” pocket and closure of the candle with a flap, which corresponds to the position of the piston blade II in figure 1. After the piston blade passes under the shutter, it opens pocket “a”. In this case, a spark discharge occurs in the short-circuited ignition system, which ignites the fuel mixture, the gases formed press on the surface “N” of the piston blade and on the shutter, as a supporting wall having support on the roller and resting on the surface of the containment belt, which corresponds to the position of the piston blade III .

When the piston blade I is in position, it displaces the exhaust gases with a surface “m” through the hole “e” into the exhaust manifold 10, in which the ejector 8 creates a vacuum and the engine is emptied from the exhaust gases.

The “boost” system with vacuum evacuation of engine exhaust gases together form a direct-flow circuit for efficient engine operation.

The placement of graphite seals 17, 18, 19, 21 in rectangular grooves mounted on elastic plates 22, 24 of heat-resistant steel, provides reliable sealing of the working sections of the engine and lubrication of the rubbing pairs of engine parts.
