Description

[Technical field]

[0001] The present invention relates to an internal combustion engine in which combustion energy is received directly by movable blades 4 on a rotating shaft to rotate the engine. [Background technology]

[0002] In an internal combustion engine, the reciprocating motion of a piston is generally converted to rotary motion through a crank. In a four-stroke internal combustion engine, the cylinder is equipped with an intake valve and an exhaust valve, and four strokes are performed: intake, compression, combustion, and exhaust. There are also two-stroke internal combustion engines that have been improved to perform four strokes without intake and exhaust valves, and rotary engines that do not use pistons. [Prior art documents] Summary of the Invention [Problem to be solved by the invention]

[0003] In conventional internal combustion engines, the capacity of the cylinder is limited, and the energy of combustion is exhausted immediately when the piston is pushed down, so the combustion energy is not fully used. Also, when the energy is exhausted, it makes an explosive sound, which is unavoidable in a sense. The same is true for rotary engines. Also, it is inevitable that the reciprocating motion of the piston will cause vibration.

[0004] It is well known that there have been definite advances in technology, such as improvements to improve thermal efficiency and mufflers that reduce piston vibrations and the explosive noise caused by combustion. However, there is still room for improvement in these areas.

[0005] In conventional internal combustion engines, the role of the piston was the key, but in this invention, the four steps of the internal combustion engine performed by the piston are performed by a two-layer cylinder and moving vanes, thereby addressing issues such as thermal efficiency, vibration, and noise.

[0006] An inner cylinder 2 that performs the functions of intake and compression is placed inside the rotating shaft 1, and an outer cylinder 3 that performs the functions of combustion and exhaust is placed on the outside. A movable blade 4 that moves in a pendulum-like manner between the inner and outer cylinders 2 and 3 is placed inside the rotating shaft 1, so that the tip of the movable blade is in contact with the inner and outer cylinders 2 and 3. With this action, when the movable blade 4 is in the inner cylinder 2, it performs the functions of intake and compression, and when it is in the outer cylinder 3, it performs the functions of combustion and exhaust.

[0007] In this invention, when the moving blade 4 is in the inner cylinder 2 following the movement of the rotating shaft 1, the fuel mixture (fuel mixture = air-fuel mixture) is sucked in behind the moving blade 4, while the previously sucked mixture is compressed to the right of the moving blade 4. The compressed mixture passes through the ventilation groove 6 inside the moving blade 4 and moves to the left side of the moving blade. Furthermore, when the moving blade 4 moves to the outer cylinder 3, the mixture flows into the outer cylinder 3 and is ignited and burned by the spark plug 7 in the combustion chamber. The expanding combustion gas pushes the left rear of the moving blade 4 and is transmitted to the rotating shaft. At this time, the gas that was previously burned is discharged in front of the moving blade 4.

[0008] The movement of the moving blade 4 is not done by itself, but by a cam 11 in a guide cam chamber 10 in the rotating shaft 1. When the cam 11 comes into contact with the outer guide barrier 12 in accordance with the movement of the rotary shaft, it is pushed down and moves counterclockwise. When the cam 11 comes into contact with the inner guide barrier 12 in accordance with the movement of the rotary shaft, it moves as if it is being pushed up clockwise, and by repeating this movement in accordance with the movement of the rotary shaft, a pendulum-like movement is created.

[0009] The cam 11 and the movable blades 4 are connected by a connecting shaft 13 that passes through the inside of the rotating shaft 1, and the movement of the cam 11 directly translates into the movement of the movable blades 4, creating the four processes of intake, compression, combustion, and exhaust.

[0010] In this invention, the volume of the outer cylinder 3, which burns and exhausts, can be set from the partition wall 8 of the outer wall 15 all the way around to the exhaust port 9, so it is much larger than the volume of the inner cylinder 2, which takes in and compresses. This makes it possible to fully combust and expand the mixture and transfer it to rotational energy.

[0011] In addition, the combustion gas is released after it has fully expanded, which reduces the volume of the explosion.

[0012] Also, because the present invention is piston-free, vibration is kept to a minimum. [Brief description of the drawings]

[0014] An embodiment of the present invention will be described with reference to Figs. In FIG. 1, cylinders 2 and 3 are arranged inside and outside a rotating shaft 1, and the rotating shaft 1 is surrounded by inner and outer walls 14 and 15. A partition wall 8 is provided on the outer wall side 15 to separate the outer cylinder 3 and act as a partition when the burned gas is exhausted. The movable blade 4 is installed inside the rotating shaft 1 so that it can move like a pendulum between the inner and outer cylinders 2 and 3, but the movable blade 4 cannot move like a pendulum by itself. It is connected to the guide cam 11 and the connecting shaft 13 in Figure 2, which allows it to move like a pendulum. A fuel pipe 16 is provided on the inner wall 14 of the inner cylinder 2, and connects the fuel intake port 5 to the inner cylinder 2. When the movable vane 4 is in the inner cylinder 2, the right side becomes the compression chamber and the rear side becomes the intake chamber. When the movable vane 4 is in the outer cylinder 3, the rear becomes the combustion chamber and the front becomes the exhaust chamber. The fuel mixture compressed on the left side of the inner cylinder 2 moves to the outer cylinder 3 through the ventilation groove 6 in the moving wing 4, and the combustion gases are ignited by the spark plug 7. The combustion gases push the moving wing 4, expand and burn completely, and move to the exhaust port.

[0015] 2 is a cross-sectional view of the guide cam chamber 10, where the movement of the moving blade 4 is generated. A guide cam chamber 10 is placed in a separate space within the rotating shaft 1, and a guide cam 11 is provided therein. As the rotary shaft rotates, the tip of the cam 11 comes into contact with the outer barrier 12, pushing the cam down and rotating counterclockwise. As the rotary shaft moves further, it comes into contact with the inner barrier 12, pushing the cam 11 up, repeating the pendulum motion. The cam 11 is connected to the movable blade 4 in FIG. 1 by a connecting shaft 13 that passes through the inside of the rotary shaft 1, and causes the movable blade 4 to move in a pendulum-like manner.

[0016] Figure 3 is a cross-sectional view taken along line A-A in Figures 1 and 2, showing the cylinder chambers 2 and 3 and the cam chamber 10. The two chambers are separated by inner and outer walls, with the rotating shaft 1 passing through them.

Possibility of industrial use of guiding cam chambers Conventional internal combustion engines are becoming outdated as not emitting carbon dioxide becomes the most important issue in the future, but there are still ways to utilize conventional internal combustion engines by using hydrogen as fuel. Therefore, we hope that by placing emphasis on drastically improving fuel efficiency and using resources without waste, and by making efforts such as reducing vibration and exhaust noise, it will be useful for modern social issues such as global warming and contribute to economic activity. It is expected that this technology will be used in a wide range of fields, including generators, agricultural machinery, and passenger car and marine engines.
