Description

FIELD OF TECHNOLOGY

The utility model relates to internal combustion engines.

BACKGROUND

Known rotary piston engine Felix Wankel (see patent DE 1137901 B, F01C 19/04, 1962 (1)). The Wankel engine consists of a housing, the inner surface of which is made of an epitrochoid with inlet and outlet windows for gas exchange and a triangular rotor. The rotor itself is located on a shaft containing an eccentric and mounted on bearings located in the side covers of the stator [1].

The disadvantages of the Wankel rotary piston engine are as follows: connecting the rotor to the output shaft through an eccentric mechanism, being a characteristic feature of the Wankel RPD, causes pressure between the rubbing surfaces, which, combined with high temperature, leads to additional wear and heating of the engine. In this regard, there is an increased requirement for periodic oil changes. The resource with proper operation is large enough, but oil that is not replaced on time will inevitably lead to irreversible consequences, and the engine crashes.

Known currently used piston internal combustion engines, which are the most common ICE and the main type of automobile engine. Internal combustion engines convert the chemical energy of fuel into mechanical work, using liquid fuel (gasoline, diesel fuel) or natural gas as an energy source.

Depending on the type of fuel used, the following piston ICEs are distinguished: gasoline and diesel engines.

Alternative fuels used in internal combustion engines are natural gas, alcohol fuels - methanol and ethanol, hydrogen [2].

The technical disadvantages of these internal combustion engines are: a large mass of moving parts and a large number of engine parts; reciprocating movement of the piston, limiting the frequency of rotation and causing the appearance of unbalanced inertia forces and moments from them; low efficiency, since of all piston strokes only one is “working”, the rest are “idle”; high level of noise; exhaust gas toxicity.

These technical solutions are taken as a prototype, as they have the maximum combination of essential features common with the utility model.

PURPOSE OF USEFUL MODEL AND TECHNICAL RESULT

The objective of the utility model is to create an internal combustion engine with the smallest friction area of engine parts to provide increased engine speed and power.

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.

DISCLOSURE OF A USEFUL MODEL

The proposed in the utility model solution to 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 at least one section consisting of a housing with end caps and a rotor with a shaft, according to the invention

the rotor contains grooves that divide it into at least three equal sectors in which the blades are located.

Moreover, the housing in its inner part forms a cylinder containing at least one "working" sector and at least two recesses located one after the other.

The recesses contain windows: the recesses with inlet windows are suction, the recesses with exhaust windows are exhaust.

In the end caps are figured cams, exactly repeating the contour of the cylinder.

The combustion chamber is formed when two adjacent blades are in the "working" sector.

Each blade contains two leashes located at the two ends of the blade, which set it in motion, describing the figured cams, precisely repeating the contour of the cylinder.

IMPLEMENTATION OF A USEFUL MODEL

Distinctive features of the claimed internal combustion engine are:

circular rotation of the rotor;

the presence of at least one engine section;

the presence of a rotor divided by grooves at least into three equal sectors in which the blades are located;

the presence of a housing, which in its inner part forms a cylinder containing at least one “working” sector and at least two recesses located one after another;

recesses with inlet windows - suction, recesses with exhaust windows - exhaust;

the presence of end caps containing shaped cams that closely follow the contour of the cylinder;

the difference is that when two adjacent blades are in the "working" sector, a combustion chamber is formed;

the drive of each blade with the help of two leads located at the two ends of the blade and describing the figured cams, exactly repeating the contour of the cylinder.

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

The operation of the rotary vane engine (Fig. 1 and 2) is as follows. When the rotor 7 moves, the first blade enters the suction recess 4, the inlet windows 2 open, the volume increases, and a vacuum is created. A combustible mixture enters the rarefaction zone through the inlet windows 2, and suction begins. The first blade enters the "working" sector, the second blade closes the inlet windows 2 and compresses the working mixture, the volume decreases, compression occurs. At the end of the compression stroke, both of these blades are in the "working" sector, forming a combustion chamber 6. The compressed working mixture ignites, combustion occurs. The gases generated in the combustion process, expanding, perform work aimed at the rotation of the rotor 7. The first blade enters the exhaust recess 5, the volume increases, expansion begins. The rotor 7 continues to rotate, the outlet windows 3 open through which the removal of combustion products is carried out. The volume begins to decrease, the second blade closes the exhaust windows 3. The entire cycle is completed in half a revolution of the rotor 7. Such two cycles pass every two adjacent dampers per revolution of the engine.

Thus, the internal combustion engine according to a utility model provides the opportunity 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.
