032399 B1

The invention relates to mechanical engineering (motor engineering) and can be used in transport.

There are a large number of inventions of rotary and rotary piston engines. In reality, only the Wankel engine works [1].

However, it is not widely used due to the high loads on the drive gears and especially on the friction surfaces of rotor parts and cylinder walls in combination with high pressure and high temperature, leading to additional wear of parts and especially sealing seals, and its extensive combustion chamber contributes to overheating engine. Therefore, this engine is difficult and expensive to manufacture and moody in operation. It also has increased fuel and oil consumption and less motor life than piston engines.

Known rocket-rotary engine and its power system.

It uses at least two jet engines mounted on the ends of the drive arms connected in a symmetrical manner to the drive shaft. They form a rotor rotating in a cylindrical circular stator with thrust bearings. The stator has windows for air inlet, exhaust gas and should cool the engine. Exhaust nozzles exit to the exhaust manifold of the stator. The engine power supply system includes a fuel pump, a main supply line with two valves (electromagnetic and pressure reducing). There is also a needle valve. [2].

The disadvantages of this engine are that: jet engines have low efficiency and their power depends on the amount of air entering the engine, that is, it depends on the speed of the air flow entering it. This means that until you rotate the engine rotor, it will not be able to do useful work.

He also has difficulties with starting, switching to high and low revs and is not stable at low revs. In addition, its cylindrical stator cannot fully ensure the fulfillment of all functions simultaneously: air inlet, exhaust gas exhaust and cooling.

Known rotary internal combustion engine. It has a combustion chamber with a valve and a nozzle, which is connected to the drive shaft by a drive lever. The drive shaft rotates with the combustion chamber on thrust bearings in a cylindrical housing with end caps on which thrust bearings are mounted and in which there are openings for venting gases. A spark plug is screwed into the cylindrical body. The combustion chamber has an opening for ignition of the fuel mixture when it coincides with the spark plug. This part of the combustion chamber touches the inner wall of the cylindrical body. Air and fuel enter the combustion chamber through the channels in the shaft and the drive lever [3].

The disadvantages of this engine are that energy is spent on overcoming the friction of the sealing seal against the body wall, and this friction occurs under high pressure and at high temperature, which will inevitably lead to its breakdown, gas breakthrough, loss of power and engine breakdown. This is facilitated by the lack of gas removal and cooling systems. The presence of holes in the ends of the housing does not solve this problem. The absence of sealing seals (which can be assumed from the description of the engine) makes it inoperative.

Known rotary explosive engine. This engine has symmetrically located combustion chambers with exhaust valves and nozzles that are connected to the drive shaft, a complex system of inlet and outlet valves and a power system [4].

The disadvantages of this engine are that its mechanical valve system takes a lot of useful energy, the exhaust valve rods pass through the combustion chambers and operate at high pressure and at high temperature, which inevitably leads to seal failure, gas breakthrough, loss of power and engine failure . Therefore, in the combustion chambers of modern engines there are only valve plates. Also, the lack of a gas exhaust system and cooling of the combustion chambers leads to engine failure.

In the present invention, these disadvantages are absent.

The technical task of the invention is to increase the efficiency (efficiency) of a discrete-mode rotary internal combustion engine due to the use of combustion chambers made at the ends of the drive levers fixed on the drive shaft and equipped with covers with automatic locking devices that unlock the covers of the combustion chambers from exposure high pressure that occurs in them after ignition of the fuel mixture and reuse of exhaust gas energy.

The power plant consists of a discrete-action rotary internal-combustion engine and systems that ensure its operation.

A discrete-action rotary internal combustion engine (hereinafter, a rotary engine) is arranged as follows.

Combustion chambers 1, equipped with spark plugs 2 and closed by covers 4 with automatic locking devices 3, are connected to the drive shaft 6 by means of drive levers 5 fixed on the drive shaft 6. The return cams 17 are made on the covers 4. Automatic

- 1 032399 shut-off device 3 can be either electronically controlled or simple mechanical, triggered (unlocked) by high pressure arising in the combustion chambers and returned to its original position by the return spring 22. Combustion chambers 1 at least two to eliminate imbalance. The drive shaft 6, equipped with compressed air and fuel intake devices, is mounted on bearings 23 and 24, the housings of which are fixed by brackets 26 and 27, on the base 33. In the drive shaft 6, an annular channel for supplying compressed air and a longitudinal channel connecting to the transverse channel are made to supply fuel. These channels are connected to the supply channels 7, made in the drive levers 5. An impeller 13 is mounted on the bearing 25 with side air inlet windows 29, the blades of which are located in the same plane of rotation with the combustion chambers 1. The impeller 13 is equipped with a drive pulley 30 mounted on it outer sleeve. An end plate 16 is also fixed on the bracket 26, on which return pushers 15 and switching devices 12 are installed, having electrical connections with electrovalves 8 and spark plugs 2. Electrovalves 8 are installed in the drive levers 5 at the entrance to the combustion chamber 1. Combustion chambers 1, the impeller blades 13 and the end plate 16 are closed by a guiding casing 14 with a side inlet window 31, which is fixed to the base 33 using the bracket 28. Compressed air comes from the compressor 9 with the drive from the drive shaft 6, and the fuel delivers tric fuel pump 10. The power supply system of this rotary engine is the same as that of conventional gasoline engines with electric power from a current generator 32, driven by a drive shaft 6. The electronic control unit 11, connected to the current generator 32, delivers through switching devices 12 on electrovalves 8 and spark plugs 2 electrical impulses of the required size and duration at the right time. The lubrication system of this rotary engine consists of a reservoir with oil 18, a pump for supplying oil 19, an oil cooler 20 and oil lines 21.

This rotary engine operates as follows.

Starting this rotary engine can be done in the same way as a conventional gasoline engine. The duty cycle is carried out at the command of the electronic control unit 11, which through the switching device 12 supplies electrical pulses to the electrovalves 8 and spark plugs

2. The electrovalves 8 open and compressed air and fuel enter the combustion chambers 1, forming a compressed combustible mixture. Then, the fuel mixture is ignited from the spark plugs 2 and a high pressure is created in the combustion chambers 1, under the influence of which automatic locking devices 3 are activated, unlocking the covers 4 of the combustion chambers 1. The covers 4 open and under the influence of the reactive force of the exhaust gases of the combustion chamber 1 begin to move drive the drive shaft through the drive levers 5. The exhaust gases also drive the impeller 13, which, in cooperation with the guide casing 14, directs the exhaust gases into the exhaust pipe (not specified). During operation of the impeller 13, atmospheric air is also absorbed (as in a centrifugal fan) through the inlet windows 31 in the guide casing 14 and the through-holes 29 in the impeller 13. This allows cooling of the combustion chambers 1 and other elements. Under the influence of exhaust gases, the impeller 13 acquires high kinetic energy, which is used to perform additional useful work; for this, a drive pulley 30 is installed on the outer sleeve of the impeller 13.

The duty cycle of this rotary engine consists of inlet, ignition and exhaust, since the air already comes compressed to the desired value by the compressor 9.

The covers 4 are closed and locked by automatic locking devices 3 during the interaction (impact) of the return cams 17, made on the covers 4, with return pushers 15 and the operation of the return spring 22.

Lubrication of this rotary engine is as follows.

The bearings 23, 24 and 25 are lubricated and cooled by the flow of oil supplied by the pump 19 from the oil reservoir 18 through the oil cooler 20 through the oil lines 21.

Thus, the advantages of the presented technical solutions are that the presence of covers 4 on the combustion chambers 1, equipped with automatic locking devices 3 that open from high pressure, makes it possible to create the pressure of the fuel mixture before ignition, and this significantly increases the energy of combustion of the fuel mixture and fuel efficiency, and also simplifies the design of this rotary engine, eliminating the complex mechanical system of intake and exhaust valves;

the use of kinetic energy of the impeller 13, equipped with a drive pulley 30, to perform additional useful work also increases the efficiency of this rotary engine.

Examples of the use of the invention are not given, since its use follows from the description.
