Description

ROTARY ENGINE

Relevant Technical Field

The present invention relates to a rotary engine, which is for use in the internal combustion engines and which comprises two or more than two combustion chambers.

Prior Art

The engines operate based on the principle of self-ignition of the fuel injected into the air, which is compressed and the pressure and temperature of which are increased. Accordingly, the conversion of heat into the work occurs in the following way. First, the clean air gets sucked or filled into the engine cylinders. The pressure of the air compressed by a piston is in the range of about 30-40 kg/cm2 and the temperature thereof is in the range of about 400-600°. Thus, the combustion follows the ignition and the gases with a pressure in the range of 40-80 kg/cm and a temperature in the range of 400-600° are formed. These hot gases with high pressure transfer the work to the crankshaft with the help of a piston and a piston rod (connecting rod). While this is happening, a great portion of the heat energy that is generated upon the combustion of the fuel is converted into the mechanical energy, which enables the crankshaft to rotate. The crankshaft enables the generation of the electrical energy by utilizing the rotary motion transmitted to it to rotate the rotor of the alternator. At the end of the work stroke, the gases the pressure and temperature of which have decreased are exhausted into the atmosphere and the step of filling the clean air into the cylinders is repeated for a new cycle.

Described herein is a rotary engine capable of providing a solution for the drawbacks of the engines of the prior art, which involve the exhaust and intake processes being performed at different times according to the operating principles thereof, i.e. the drawbacks arising from the inability to transfer all the power due to the crankshaft angle of 720° and from the high fuel consumption. Object of the Invention

An object of the present invention is to realize a rotary engine, which enables the exhaust and compression to take place simultaneously and the intake and ignition to take place simultaneously and which will be able to provide a solution for the high fuel consumption of the other engines.

The rotary engine according to the invention (Figure le) comprises a part 1 ( 1 ) in the form of a single-piece with a cylinder shaped exterior section (lc), a cylinder shaped central section (l b) and a shaft shaped interior section (la). The cylindrical part 2 (2) of the rotary engine according to the invention is able to overlap with the central section (lb) of the part 1 (1) (Figure 2a).

When the part 2 (2) moves in the direction of the arrow, the combustion chamber (6) (Figure 3a) and the combustion chamber (7) (Figure 4a) appear. The combustion chamber (6) includes the intake manifold (3a), the exhaust manifold (4a) and the ignition unit (5a) and the combustion chamber (7) located on the other side includes the intake manifold (3b), the exhaust manifold (4b) and the ignition unit (5b), wherein the combustion chamber (6) and the combustion chamber (7) are disposed opposite one another on two sides of the rotary engine (Figure 3a, Figure 4a). Figures 2a-2k schematically illustrate the operating principle of the combustion chamber (6) present in the rotary engine according to the invention. Referring to the work stroke of the combustion chamber (6) in Figure 2b, the intake stroke occurs in the combustion chamber (6) upon the motion of the part 2 (2) in the direction of the arrow. Said intake process continues until Figure 2g and after this motion, the sucked air and fuel begin to be compressed (Figure 2h) and the compressed air and fuel are stored in the air and fuel storage area (8) of the combustion chamber (6) (Figure 2k).

At this point, the part 2 (2) is pushed in the direction of the arrow by means of the pressure that has developed as a result of the combustion taking place in the combustion chamber (6) (Figure 3a).

Owing to this motion, the intake process is caused to occur in the combustion chamber (7) on the other side (Figure 4a). Throughout this motion, the combustion continues in the combustion chamber (6) (Figures 3a-3d) and the intake process continues in the combustion chamber (7) (Figures 4a-4d). As a result of this motion, the exhaust is stored in the combustion chamber (6) (Figure 3d) and the sucked fuel is stored in the combustion chamber (7) (Figure 4d).

The continuation of this motion in this direction causes the discharge of the exhaust in the combustion chamber (6) (Figure 3e) and the compression of the sucked fuel in the combustion chamber (7) (Figure 4e). As a result of the process, the exhaust has been discharged from the combustion chamber (6) (Figure 3f) and the sucked fuel has been compressed and stored in the air and fuel storage area (8) of the combustion chamber (7) (Figure 4f), As the continuation of this motion, the work stroke intake process is carried out in the combustion chamber (6), while the ignition and the generation of the pressure and power are performed in the combustion chamber (7) on the other side.

Owing to the facts that, in the rotary engine according to the invention a cycle of which has been described above, the intake and ignition take place simultaneously and the compression and exhaust take place simultaneously, the process continues without any stopping being required and the operation takes place without any greater extent of motion being necessary with respect to the 4-stroke engines, the rotary engine according to the invention will be able to provide solutions for the problems in the other engines. Consequently, with the rotary engine according to the invention, more power may be generated as compared to the 4-stroke cylinders. Some of the preferred embodiments of the rotary engine according to the invention are illustrated in the enclosed drawings, which are not intended to limit the invention.
