Description

Rotary engine

The present invention relates to a rotary engine in which a rotational motion of a rotor (4) is directly transmitted to a driving shaft, and implements a process of suction, compression, explosion, and exhaust of a reciprocating engine as a simple structure. The present invention relates to a rotary engine capable of maximizing efficiency during intake and exhaust, reducing vibration, reducing fuel, and improving output because there is no intake and exhaust valve.

In order to improve the mechanical deficiency of the piston reciprocating engine, various rotary engines have been developed for converting thermal energy into direct rotational motion. The Wankel engine, which consists of four strokes such as suction, compression, combustion, and exhaust, is a rotary engine using various rotary engines and rocket propulsion principles designed to compensate for structural defects. Rotary engines, such as rotary engines, have been difficult to be used due to problems such as structural complexity and fuel consumption efficiency or power and durability. In particular, in case of rotary engine, which is eccentric rotation, contact between rotor 4 and cylinder is caused by eccentric rotation, which requires high precision when manufacturing for airtightness and the impact of explosion is concentrated on a part. Because of the contact, the engine contained fatal structural defects, which made it difficult to maintain airtightness and also caused a high failure rate. In the case of the rotary engine, which is a concentric rotation, the structure of the auxiliary device for the compression and explosion operation of the fuel gas is complicated, and thus the practical use of the engine is not practical due to heavy gas or problems such as many failures. .

The present invention deviates from the conventional stereotypes of the rotary engine developed in order to solve the above problems and above all violates the law of inertia by the energy obtained by the explosion by concentric rotation with a simple structure. It is an object of the present invention to obtain durability and high speed rotation and high output due to high fuel saving and significant vibration reduction by obtaining power without circular motion alone.

In order to achieve the above object, the present invention includes a rotor (4) integrally formed on a rotating body (2) rotating a coaxial shaft, and a housing cylinder (1), which is a concentric circle. The rotor 4 is circularly moved inside.

At this time, the rotor (4) serves as a piston and a cam at the same time, and the opening and closing of the partition and the opening and closing of the partition using other cam devices or electromagnets are performed together to continuously operate the suction, compression, explosion, and exhaust. There is a characteristic in this being done.

1 is an exploded perspective view of some of the major components of the present invention.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the present invention is configured such that the rotor 2 and the rotor 4 are integrally formed around the axis of rotation 3 to rotate in a housing cylinder 1. Outside the housing cylinder (1) there is an inlet (8) and an exhaust port (9), there is a third partition (7) in between, and in the upper portion of the housing cylinder (1) There are two first and second partitions 5 and 6, between which a spark plug 13 and an injector 14 are constructed.

At this time, the movement of the third partition 7 moves the rotor 4 according to the shape of the rotor 4 like a cam, and the first and second partitions 5 and 6 move the rotor ( Rotor) (4) by using the movement of the cam device or the electromagnet device together to open and close at an appropriate timing.

2 is a view showing the operation of each cycle.

(1) of FIG. 2 is a step of compressing the inhaled air in which the first partition 5 is forcibly opened and the second and third partitions 6 and 7 are closed by the force of the spring 11.

2 is a time point at which fuel is injected from the injector 14 in the state of the end of compression and the forced opening of the first partition 5 is released and closed.

(3) of FIG. 2 shows a housing cylinder 1 in which the position of the compressed mixed gas is moved back and forth in front of the rotor 4, which is larger than the radius of the rotor 4. The mixed gas is moved to the groove 16 between, and the ignition starts immediately after the movement.

FIG. 4 (4) is an explosion (expansion) process, in which the second partition 6 is in a forced-open state, and air in front of the rotor 4 exits through the exhaust port 9.

2, FIG. 5 shows that the exhaust gas is discharged through the exhaust port 9 as the rotor 4 passes through the exhaust port 9 and the third partition 7.

In FIG. 2 (6), the third partition 7 is closed again according to the shape of the rotor 4, and the suction of air from the inlet 8 starts as the rotor 4 rotates. .

(7) of FIG. 2 shows that the first partition 5 is also forced to open as the suction of air starts (thus, the first and second partitions 5 and 6 are both open) and the rotor 4 is opened. Rotation until passing through the third partition 7 completes the elimination of residual gas and the intake of new air in the cylinder.

Again, in FIG. 2 (1), when the rotor 4 passes the third partition 7, the second partition 6 is also closed, and compression is started again, thereby completing one cycle.

As described above, according to the present invention, the rotary engine has a simple structure, reduces weight, reduces vibration, high speed rotation, high output, and intake / exhaust valves, thereby increasing efficiency at intake and exhaust. The sliding drive by contact makes excellent lubrication and airtightness, and high fuel saving effect is expected.
