Abstract

A rotary engine capable of generating stable and efficient rotation on three sides of a triangular rice ball-shaped rotor of the rotary engine and improving output and torque. SOLUTION: A wedge-shaped concave portion is installed on each side of three sides of a triangular corn-shaped rotor of a rotary engine at a position where the wedge-shaped concave portion functions as a combustion chamber. The cross section is large in the direction in which the rotor rotates, and the wedge thickness is reduced toward the other end. In this rotary engine, a force acts in a direction in which the cross-sectional area is large due to the wedge-shaped concave portion at the time of explosion, and the rotor rotates in a certain direction 104 (direction in which the wedge-shaped concave portion becomes thick). As a result, only one spark plug is required, and the output and torque are improved. [Selection] Figure 1

Description

  The present invention relates to a rotary engine in which a triangular rice ball-shaped rotor rotates and outputs by a series of intake, combustion expansion, and exhaust processes.

The operation of a rotary engine is difficult to understand compared to a reciprocating engine such as a 4-cycle or 2-cycle. In the case of reciprocating, the piston reciprocates, so the positional relationship is clear and easy to understand, but in the case of a rotary engine, even if the triangular rotor rotates, the same vertex moves, so the position of the Confirmation is difficult, and control of the direction of rotation is one of the challenges of developing a rotary engine.
Japanese Patent No. 2920563

  FIG. 7 is a cross-sectional view for explaining an operation process from the ignition of the conventional rotary engine to the explosion and exhaust.

  In a rotary engine, a rotor corresponding to a piston in which the side surface of a cylinder is inscribed in an eyebrows-shaped rotor housing is mounted on a shaft with a misaligned core and freely rotates. A gear which is fixed around and does not rotate is installed, and the inner teeth of the rotor mesh with the gear. The rotation of the rotor produces the rotation of the shaft and is taken out as output. The rotary engine generates smooth rotation by smoothly and continuously repeating four cycles of intake, compression, explosion, and exhaust.

  FIG. 7 shows a change in the engine while the rotor rotates about 120 degrees in the direction of the arrow 104. In the rotary engine, assuming that the three vertices of the triangular rice ball-shaped rotor 110 are A, B, and C, when the rotor rotates, the volume changes between each of the three sides and the inner wall surface of the rotor housing 100 at a constant cycle. Three working chambers are created. Therefore, the size of each working chamber changes during four cycles of intake, compression, explosion, and exhaust according to the rotation of the rotor.

  When attention is paid to the working chamber 301 between the side AC and the inner wall surface of the rotor housing 100, the volume of the working chamber 301 is sequentially increased with the rotation of the rotor by sucking air from the suction port 115.

In the working chamber 302 between one side AB of the rotor 110 and the inner wall surface of the rotor housing 100, the air in the working chamber is compressed and the volume is sequentially reduced according to the rotation of the rotor. The air in the working chamber expands and the volume increases.
In the case of the concave portion installed on the side surface of the conventional rotor, since the force that expands due to the explosion cannot be controlled in a certain direction, the number of spark plugs is two and the rotor 110 is adjusted by adjusting the ignition timing. It was rotating in a certain direction.

  The working chamber 303 between one side BC of the rotor 110 and the inner wall surface of the rotor housing 100 is gradually exhausted from the exhaust port 116 according to the rotation of the rotor at the same timing. Decreases sequentially.

  As described above, the rotor rotates 1/3 while the shaft rotates once, and in each of the three sets of working chambers, one of the four cycles of intake, compression, explosion, and exhaust proceeds. Therefore, during one rotation of the rotor, three sets of four-stroke processes of intake, compression, explosion, and exhaust will proceed. Smoothly and continuously repeating the four cycles of intake, compression, explosion, and exhaust is indispensable for producing smooth rotation of the rotary engine, and the influence of the rotational force of the rotor on the engine is great.

  When the rotor rotates, three working chambers are formed between the sides of the rotor and the inner wall surface of the rotor housing. In the present invention, by providing a wedge-shaped recess on the side surface of the rotor, it is possible to rotate the rotor more smoothly and efficiently from the characteristics of the shape of each of the three working chambers in the compression process and the combustion stroke. Realizes high engine output and high torque.

The invention described in claim 1 is a rotary engine,
On each side of the three sides of the triangular rice wheel-shaped rotor of the rotary engine, a wedge-shaped recess is installed at a position that functions as a combustion chamber,
The wedge-shaped recess has a shape finished so that the thickness of the wedge increases in the direction in which the rotor rotates, the cross-sectional area increases in the direction in which the rotor rotates, and the thickness of the wedge decreases toward the other end. It is the shape which becomes.

The invention described in claim 2 is the rotary engine according to claim 1,
The rotary engine has one spark plug.

  According to the present invention, a wedge-shaped recess is provided on the three side surfaces of a triangular rice ball-shaped rotor that is inscribed in the rotor housing of the rotary engine, thereby generating stable and efficient rotor rotation, high output and torque. Can be improved.

Hereinafter, the best mode for carrying out the invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is a cross-sectional view for explaining a rotary engine according to the first embodiment.

  In FIG. 1, 100 is a rotor housing corresponding to a cylinder, and 110 is a rotor having a triangular rice ball shape inscribed in the cylinder. A rotor 110 corresponding to a piston is attached to a shaft 120 with a misaligned core and freely rotates, but in order to control the rotation, a gear 121 that is fixed around the shaft 120 and does not rotate is installed. The inner teeth 118 of the rotor mesh with each other around the gear 121. Here, the rotor is rotating in the direction of the arrow 104. Reference numeral 115 denotes an intake port, 116 denotes an exhaust port, and 117 denotes a spark plug.

  In the case of the concave portion installed on the side surface of the conventional rotor, since the force that expands due to the explosion cannot be controlled in a certain direction, the number of spark plugs is two and the rotor 110 is adjusted by adjusting the ignition timing. It was rotating in a certain direction.

  In the rotary engine according to the present invention, a force acts in a direction in which the cross-sectional area is large due to the wedge-shaped recess during explosion, and the rotor rotates in a certain direction 104 (direction in which the wedge-shaped recess becomes thicker). As a result, only one spark plug is required, and the output and torque are improved.

  Reference numeral 111 denotes a wedge-shaped concave portion provided on the side surface of the rotor 110 according to the present invention. Reference numeral 101 denotes a working chamber between the side of the rotor having the concave portion 111 and the inner wall surface of the rotor housing 100. Reference numeral 102 also denotes a working chamber between the other side of the rotor and the inner wall surface of the rotor housing 100, but at this timing, it is compressed and smaller than 101. Reference numeral 103 denotes a working chamber between the other side of the rotor and the inner wall surface of the rotor housing 100. 112 and 113 are wedge-shaped recesses having the same shape as 111 provided on the side surface of the other side of the rotor.

  The shapes of these three concave portions are the same, and in the direction 104 in which the rotor rotates, a wedge shape is formed by thickening one end of the wedge shape and thinning it toward the other end. Due to this shape feature of 111, 112, 113, the rotor can rotate more smoothly in a certain direction (104), and during one rotation of the rotor, three sets of four cycles of compression, explosion, and exhaust. The process proceeds smoothly. As a result, high output of the rotary engine can be realized.

  2, 3, 4, 5, and 6 show three sets of intake and compression in the three working chambers 101, 102, and 103 during one rotation of the rotor of the rotary engine according to the first embodiment. It is the figure which demonstrated sequentially a mode that the process of 4 cycles of explosion and exhaust_gas | exhaustion progressed.

  2 to 6, focusing on the movement of the vertex A of the rotor 110 according to the present invention, the change in the volume of the working chamber accompanying the rotation of the rotor is shown. Each figure shows a state when the rotor is rotated by about 90 degrees in the rotor rotation direction (104), and FIG. 6 returns to the position of FIG. Thus, by smoothly and continuously repeating the four cycles of intake, compression, explosion, and exhaust, the shaft rotates and a smooth rotation of the rotary engine is produced. By providing a wedge-shaped recess on the side of the rotor as in the present invention, the rotation direction of the rotor is stabilized, a more stable large rotational force is generated, and the smooth rotation of the rotor can be performed continuously. The output and torque can be improved.
