FIELD OF TECHNOLOGY

The invention relates to the field of engine building, in particular to rotary internal combustion engines, and can be used as a power plant in land, air and water transport.

BACKGROUND

Known rotary internal combustion engine US patent No. 6539913. A rotary internal combustion engine comprises a housing, a rotor, two compression cams and an ignition chamber. Two blades are installed in the radial grooves of the rotor. A compression cavity and an exhaust cavity are formed between the inner surface of the housing and the rotor. The ignition chamber is connected to the compression cavity and the exhaust cavity by channels [1].

The disadvantage of a rotary internal combustion engine is the complex shape of the inner surface of the housing.

This technical solution is taken as a prototype, as it has the maximum combination of essential features common with the invention.

OBJECT OF THE INVENTION AND TECHNICAL RESULT

The objective of the invention is to increase efficiency, engine power and the maximum simplification of the design.

The technical result is a simplification of the design and material consumption of the internal combustion engine, reducing the mass of moving parts, reducing the number of parts.

SUMMARY OF THE INVENTION

Proposed in the invention, the solution of the above problem, the achievement of the goal and the required technical result, is ensured by the fact that in an internal combustion engine containing an air compressor with a receiver, which serves to create the necessary air pressure in the combustion chamber, a cylinder body with end caps and a cylindrical rotor with a shaft mounted with an eccentricity with respect to the inner surface of the cylinder.

In this case, the cylinder body contains a separate rotating combustion chamber, configured to drive from the rotor shaft, an inlet channel of compressed air into the combustion chamber, at least one bypass channel of the working gases from the combustion chamber located at the beginning of the zone of increase in volume in the cylinder and at least one outlet port located at the end of the volume reduction zone in the cylinder.

Each end cap contains a cylindrical cam located on the same axis with the axis of the cylinder.

The rotor is divided by grooves into at least two equal sectors in which the blades are located.

Each blade is driven by two cylindrical cams.

Below the invention is described in more detail with reference to the drawings attached to the description, which show, by way of example, preferred, but not necessary, options for the possible implementation of the invention, the structural embodiment and operation of the internal combustion engine proposed in the invention.

DETAILED DESCRIPTION OF THE INVENTION

Distinctive features of the claimed internal combustion engine are:

circular rotation of the rotor;

the presence of a rotor mounted with an eccentricity with respect to the inner surface of the cylinder, divided by grooves into at least two equal sectors in which the blades are located;

the presence of a housing that contains a separate rotary combustion chamber configured to drive from the rotor shaft, an inlet channel of compressed air into the combustion chamber, at least one bypass channel of the working gases from the combustion chamber located at the beginning of the expansion zone in the cylinder and at least one outlet port located at the end of the volume reduction zone in the cylinder;

the presence of end caps containing cylindrical cams located on the same axis with the axis of the cylinder;

driving each blade with two cylindrical cams;

the ability to change engine power by adjusting the pressure of compressed air and the amount of fuel supplied to the combustion chamber.

The operation of the internal combustion engine according to the invention is as follows and will be shown on the example of a rotary vane engine with a separate rotating combustion chamber (Fig. 1 and 2):

The operation of the rotary vane engine with a separate rotating combustion chamber (Fig. 1 and 2) is as follows. The compressor creates the necessary air pressure in the receiver, connected by a pipeline to the inlet channel 8. The combustion chamber 7, driven by gears 12 and 13, is connected to the inlet channel during rotation 8. Compressed air enters the combustion chamber 7, the inlet channel 8 closes, the nozzle 9 delivers fuel. The resulting working mixture is ignited, combustion occurs. The combustion chamber 7 continues to rotate and is connected to the bypass channel 10. The gases generated during the combustion process through the bypass channel 10 enter the cylinder, expanding, create pressure on the blade 5 and perform work aimed at rotating the rotor 3. The volume increases, expansion begins. The rotor 3 continues to rotate, the first blade opens the exhaust window 11, through which the removal of combustion products. The volume begins to decrease, the second blade closes the outlet window 11.

Thus, the internal combustion engine according to the invention provides the ability to achieve the desired technical result, namely, simplifying the design and material consumption by reducing the number of parts, their mass and increasing its compactness.

Individual parts and components of the inventive internal combustion engine can be manufactured using materials and technologies known in the engineering industry.

Specific dimensions and individual design features of individual parts and assemblies can be selected from standard sizes and standards of industrial engineering.
