Description

FIELD OF THE INVENTION The invention relates to engine construction, namely, to rotary internal combustion engines.

A rotary internal combustion engine is known, comprising a housing with a profiled working surface, end caps, a cylindrical rotor mounted on a shaft and provided with swinging pistons in contact with

profiled working surface of the housing and forming above-piston and sub-piston working volumes, gas exchange system, made in the form of inlet and exhaust ports, and spark plugs 1.

The disadvantage of such an engine is the imperfect combustion process of fuel in a segment combustion chamber with large heat losses due to the fact that its shape is far from optimal-spherical.

The aim of the invention is to improve the combustion of fuel.

The goal is achieved by the fact that in a rotary internal combustion engine, comprising a housing with a profiled working surface, end caps, a cylindrical rotor mounted on a shaft and provided with oscillating forces in contact with the profiled working surface of the housing and forming supra-piston and subspawn volumes, the system gas exchange, made in the form of inlet and exhaust ports, and spark plugs, each piston is equipped with a combustion chamber and a bypass channel with a check valve that informs the chambers in the combustion with the Subgeneral Volume, and the inlet ports and the plugs for the spark plugs are made in the end cap with the ability to communicate the windows with the sub piston volumes, and the plugs with the combustion chambers.

The drawing shows a cross-section of a rotary engine.

The engine includes a housing 1 with a profiled working surface, a cylindrical rotor 2 mounted on the central shaft 3 and equipped with swinging pistons 4 in which the combustion chambers 5 are located, and the bypass channels BS with spring-loaded non-return valves 7 separating the piston-piston volumes 8 and the combustion chamber 5 . The end caps 9 are provided with inlet openings 10 and openings 11 for candles. Outlets 12

located in housing 1 and communicating with over-piston volumes 13. The pistons 4 are mounted on axles 14 and are spring loaded 15. The pistons and housing have

seals 16.

The engine works as follows.

When the rotor rotates 2 Porschni 4 under the action of springs 15 and centrifugal forces

slide the upper edges along the working surfaces of the housing 1, making swinging movements between two extreme positions: fully extended and fully retracted into the rotor body.

In the position of the bodies 4, fully retracted into the body of the rotor 2, the combustion chambers 5 communicate with the spark plug openings 11, and the working mixture in the compression chamber ignites. When the plenum chamber 5 is extended, the combustion chamber communicates with the thrashing volumes 13 and the gases expanding in the combustion chamber into the above piston volume 13, producing a useful rotational operation of the rotor.

At the same time, the inferior volumes 8

5 communicates with the inlets 10, and due to the release of volume from the piston, they are forced into the working mixture.

At the same time, the front side of the piston 4 pushes the gases exhausted from the previous cycle into the exhaust ports 12 from the over-piston volume 13, and discharges. When the rotor 2 is further rotated, the inlets 10 are separated from the podfing gaps 8, the pores 4 are retracted into the rotor 2 body, compressing the working mixture in the pied pore 8. At the same time, the check valves 7 are opened, the working mixture from the podporny volume is opened into the combustion chamber 5 - the bypass .

Thus, with one full swing, the full thermodynamic cycle occurs, all pistons working simultaneously and synchronously, and the number of operating cycles occurring in the engine per rotor rotation is equal to the square of the number of pistons. At the same time, this design allows the combustion chamber with a shape close to spherical to be realized in the engine, and thereby improve the combustion of the working mixture.
