Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary engine which can reduce fuel consumption and can efficiently save energy and prevent environmental pollution.

[0002]

2. Description of the Related Art With the development of science and technology, various internal combustion engines have been developed to occupy most of the power of automobiles and airplanes, and are widely used in all other fields. With regard to automobile engines, with the improvement of the highway network, safety has been taken into consideration and speeds are being promoted.

[0003]

Looking at such a current rotary engine, the conventionally known Wankel rotary engine or patent registration number 908705.
10 and 11, the pressures acting on the rotary piston in both the rotary type internal combustion engine are pressure P ₁ and pressure P ₂ , and since the pressure P ₂ acts in the direction opposite to the rotation direction of the rotary piston, it is eccentric. The force exerted on the shaft becomes pressure P ₁ -pressure P ₂ , which is inefficient and is very inconvenient for using the rotary engine.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve such inconveniences, to eliminate energy loss, and to provide an efficient rotary engine. First, the principle of the rotating body and the curved surface of the casing will be described with reference to the drawings. Let O be the center point of any square A, B, C, D, and straight lines A, B
Is the side N ₁ , the straight lines B and C are the side N ₂ , the straight lines C and D are the side N ₃ , and the straight lines D and A are the side N ₄ , then N ₁ = N ₂ = N ₃ = N ₄ =. At this time, passing through the center point O, the center points E _{1 of} the sides N ₁ , N ₃
The arm M ₁ to E _3, when connecting the arm M ₂ to the center point E _2, E ₄ sides N _2, N ₄ through the center point O, the arm M _1, M ₂ are orthogonal,
Moreover, the side N ₁ = arm M ₁ = arm M ₂ .

In this relationship, when the center point O is rotated by 90 ° in the direction of the arrow, the point A passes through the point F to the point B as shown in FIG. B passes through point G to the position of point C, point C passes through point H to the position of point D, point D
Passes through point I to reach the position of point A and draws an arbitrary curve.
In this way, when 360 ° is rotated once, points A, B,
The curves drawn by C and D are points A, F, B, G, C, H, D,
It is an arbitrary (trajectory of each point) curve connecting I and A.

Next, an outline of the configuration will be described based on the principle. If a rotation axis is provided at the center point O, arms M ₁ and M ₂ are piston rods, and sides N ₁ , N ₂ , N ₃ and N ₄ are rotary pistons, the length of the piston rod from the center of the rotation axis and The length of the rotary piston is 2: 1
A square rotating body in which the connecting part of each rotary piston and piston rod is rotatable by pins etc., and one piston rod is fixed to the rotating shaft and the other piston rod is slidably fitted to the rotating shaft, A casing with a curved line on its inner surface that traces the center of the connecting portion at both ends of the rotary piston when a square rotating body with a rod length and a rotary piston length of 2: 1 is rotated about the rotation axis. It is provided in the cylinder, and spark plugs, intake holes, and exhaust holes are provided at appropriate positions in the casing cylinder in correspondence with the space created.

When the rotary shaft is rotated by the driving device, the rotary body rotates, and the both ends of the rotary piston come into contact with the inner surface of the casing cylinder, and the square rotary body rotates while deforming from a parallelogram to a rhombus and then to a parallelogram. At this time, the space formed between the rotary piston and the inner surface of the casing cylinder changes from a compressed state to an expanded state as it moves along an arbitrary curve on the inner surface. The rotary piston is pushed and converted into a rotational force through the piston rod, exhausted from the exhaust hole in the compressed state again, fuel is sucked in the expanded state, and ignition is prepared in the compressed state again. By repeating the rotation of the rotary body for one rotation, the intake, compression, expansion, and exhaust strokes are sequentially performed in each rotary piston, so that the entire rotary body is performed four times.

Embodiments of the present invention will be described below with reference to the drawings. In the figure, 1 is the whole rotating body, 2 is the rotating shaft,
It is connected to a power transmission device or the like via a gear or the like. A piston rod 3 is fixed to the rotary shaft 2 at the center. Reference numeral 4 denotes a piston rod having the same size as that of the piston rod 3, and is provided so as to be idle at the center of the rotation shaft 2 by fitting or the like. Reference numeral 5 denotes a rotary piston having the same size as the piston rod 3, and is rotatably connected to both ends of the piston rod 3 by a piston pin 6 at the center.

Reference numeral 7 denotes a rotary piston having the same size as that of the piston rod 4, which is rotatably connected to both ends of the piston rod 4 by a piston pin 6 at the center, and both ends of the rotary piston 7 are connected to both ends of the rotary piston 5 and a connecting pin. 8
The square rotary body 1 is formed by rotatably connecting with a, 8b, 8c and 8d. 9 is a rotary piston 5,
7 is a casing cylinder having a curve of a locus drawn when the end portion rotates about the rotation axis 2 provided on the inner surface 10, an ignition plug 11 is provided at an appropriate position above, and an intake hole 12 and an exhaust hole are provided at appropriate positions below. 13 are provided.

Next, the operation will be described. When the driving device (starter, etc.) operates and is transmitted to the rotating shaft 2, the rotating body 1
Starts to rotate, the piston rod 3 is moved to move both ends of the rotary pistons 5 and 7 along the inner surface 10, and the rotary piston 2 is rotated about the rotary shaft 2 while being deformed into a parallelogram and a square. At this time, the inner surface 10 and the pistons 5, 7
Spaces S ₁ , S ₂ , S ₃ , and S ₄ are formed between them.

The space S ₁ is ignited by the spark plug 11 in a compressed state to explode, and is applied to the piston pin 6 as a force W ₁ during the transition to the space S ₂ and the rotational force of W ₂ with respect to the piston rod 3. Works to rotate the rotating body 1. The space S ₂ is in an expanded state after the explosion, and during the transition to the space S ₃ , the combustion gas exploded in the space S ₂ is exhausted by compression from the exhaust hole 13.

The space S ₃ is in a compressed state through exhaust gas, and sucks fuel by expansion from the intake hole 12 while moving to the space S ₄ . The space S ₄ is in an expanded state after intake, and compresses the sucked fuel during the transition to the space S ₁ so as to easily ignite. At this time, the spaces S ₁ and S ₃ and the spaces S ₂ and S ₄ are the same in shape, but the operation is different as described above. Each rotation of the rotating body 1 causes the pistons 5, 7 to go through the intake, compression, expansion (ignition, combustion), and exhaust strokes in order to generate power and transmit the rotation from the rotary shaft 2.

[0013]

As described above, the present invention is well balanced even with a single rotor, and since a crankshaft, an eccentric shaft, etc. are not required, the structure is simple and robust, and the manufacturing cost is reduced. Compared to the currently used rotary engine, it has no reciprocating motion, and since it does not work in the reverse rotation direction, it has many features such as no energy loss, less fuel consumption, and economical. It is a very excellent invention.
