Description

Technical Field

[0001] The invention relates to the technical field of fuel engine, in particular to a piston cyclic rotation fuel and gas engine. Background Art

[0002] The fuel and gas engines currently used and sold on the market have various problems such as complex structure, high energy consumption, low efficiency, and high noise.

[0003] A piston reciprocating four-stroke fuel and gas engine is composed of a piston, a cylinder, a crankshaft, a valve, and a connecting rod. Each time the piston does work, it must complete four strokes, namely, intake, compression, power, and exhaust. The disadvantages are: (i) Only the power stroke is the process of actively outputting kinetic energy, while the other three strokes are all consuming kinetic energy, especially the compression stroke, which consumes a lot of energy. (ii) Since the crankshaft is used to transmit kinetic energy, the lever principle is used, and there are effort-saving levers and effort-consuming levers. In the process of the piston transmitting kinetic energy to the crankshaft through the connecting rod, an angle will appear from small to large and from large to small. When the angle is small, it is an effort-consuming lever, which will consume a lot of energy, but the output energy is very small. When the angle is large, it is an effort-saving lever, and the energy consumed is relatively small. However, there are two effort-consuming lever sections (the initial and final stages of power) and one effort-saving lever in a power stroke. The stroke of the effort-consuming lever is greater than the stroke of the effort-saving lever, and the energy wasted is greater than the energy saved. (3) Due to the limitations of structural design and working mode, the working gas cannot completely release its energy and is discharged out of the cylinder, resulting in a large amount of energy waste. The gas carrying energy will release a huge noise. Therefore, the above three points show that the piston reciprocating engine consumes a lot of energy, wastes a huge amount of energy, outputs very little energy, and makes a lot of noise.

[0004] The gas turbine engine is composed of a compressor, a combustion chamber and a turbine. The compressor, the combustion chamber and the turbine are installed in series on the same shaft. The compressor compresses the air into high-pressure gas which enters the combustion chamber to mix with the fuel. After the explosion, the volume of the gas expands several times and is sprayed toward the turbine blades at high speed, so that the turbine generates torque to drive the shaft to rotate to complete the work. Since the turbine blades are deflected at a certain angle, the high-speed flowing gas is not blown vertically to the turbine blades, and the energy carried by the high-speed flowing gas cannot be fully applied to the turbine blades, resulting in a lot of energy waste. The compressor also consumes a lot of kinetic energy when working. In addition, the high-speed gas after work still carries a lot of energy, which causes waste. The explosion sound generated when the gas explodes is released without obstruction, so the noise is extremely large. The overall disadvantages are: energy loss and waste are very large, the energy consumption itself is very high, the energy that can be output is very small, and the noise is extremely large.

[0005] In order to solve these shortcomings, I developed this piston cycle rotary engine with simple structure, high efficiency, low cost and low noise. Summary of the invention

[0006] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of the present invention to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0007] The purpose of the present invention is to solve the technical problems existing in the background technology. The present invention proposes a piston circulating rotation fuel and gas engine. The present invention adopts a piston rotating around the axis to do work. The inertia generated by the piston rotation can be sustained. Each time the piston does work, it can be boosted again based on the inertia generated by the previous work rotation, which can save a lot of energy. When the piston of the piston reciprocating engine is doing work, the inertia generated by each stroke of the piston must drop rapidly to zero at the end of the stroke, and the impact force generated by its inertia must be borne by the body, which places very high requirements on the structural strength of the body. When performing the next stroke, the inertia generated by the static state of the piston must be overcome and a certain amount of energy must be consumed. Therefore, the piston of the piston reciprocating engine itself consumes a large amount of energy when doing reciprocating motion. The present invention adopts a continuous same-direction rotation to do work, so that the rotational inertia of the piston and the turntable generated by the fuel and gas work can be continuously maintained, thereby improving fuel utilization.

[0041] The spark plug component 7 includes a spark plug connector 701 connected to the outer arc surface of the circular shell 1, the spark plug connector 701 is provided with an electrical connector, a spark plug shell is provided at the bottom of the spark plug connector 701, the spark plug shell is through-connected to the outer arc surface of the circular shell 1, an ignition electrode 702 is provided inside the spark plug shell, the ignition electrode 702 faces the inside of the circular shell 1, and there is a gap between the bottom of the ignition electrode 702 and the top of the piston 601.

[0042] The nozzle component 8 includes a nozzle shell 801 connected to the outer arc surface of the circular shell 1, the inner arc surface of the nozzle shell 801 is wrapped with a pressure tube 802, a gap is left between the inner arc surface of the nozzle shell 801 and the pressure tube 802, a feed joint is connected to the top of the pressure tube 802, a control valve 803 is connected to the inner side of the bottom of the pressure tube 802, an oil-gas mixing nozzle 804 is connected to the bottom of the pressure tube 802, the oil-gas mixing nozzle 804 faces the inside of the circular shell 1, and there is a gap between the bottom of the oil-gas mixing nozzle 804 and the top of the piston 601, the nozzle component 8 is arranged near the side of the rotating gate component 5, a spark plug component 7 is provided on the side of the nozzle component 8 away from the rotating gate component 5, and an exhaust port 4 is provided on the opposite side of the rotating gate component 5 away from the nozzle component 8.

[0043] The specific working principle is: this device can avoid the method of using the traditional reciprocating piston sliding work method to perform work in the internal combustion engine. Compared with the traditional device, the piston 601 of this device always rotates continuously in the same direction inside the circular shell 1, so the rotational inertia can always be maintained, thereby improving fuel utilization.

[0044] The device divides the piston working process into three stages, namely the intake stage, the working exhaust stage, and the end reset stage.

[0045] During the intake stage, the piston 601 is located at position A, and the rotating gate plate 502 rotates to a state where the solid part is located inside the circular shell 1. At this time, a sealed space is formed by the inner wall of the circular shell 1, the outer arc surface of the turntable 2, the side of the piston 601 and the side of the rotating gate plate 502. After the sealed space is formed, the oil and gas mixed fuel is atomized and sprayed into the sealed space through the nozzle component 8.

[0046] During the work and exhaust stage, when the piston 601 rotates from point A to point B according to inertia, the spark plug component 7 ignites the oil and gas mixed fuel atomized in the sealed space. At this time, the fuel explodes, causing the gas in the sealed space to expand rapidly. The expansion generates thrust, which pushes the side of the piston 601 to achieve work on the piston 601. Since the rotating gate 502 is in a closed state, the sealed space can only expand the internal space through the rotation of the piston 601, thereby achieving the effect of the fuel pushing the piston 601 to do work. At this time, the piston 601 rotates counterclockwise in the attached figure. When the piston 601 rotates, the exhaust gas remaining from the last combustion remains on one side of the piston connector 602, and the piston 601 pushes the exhaust gas to be discharged from the exhaust port 4.

[0047] At the end of the reset stage, the piston 601 reaches the position at point C after one circle of rotation. At this time, the rotating mechanism drives the rotating shaft 505 to rotate, thereby realizing the rotation effect of the rotating gate 502. When the piston 601 passes the position of the rotating gate 502, the rotating gate 502 rotates to the angle where the arc-shaped through groove 503 is located inside the circular shell 1, so that the piston 601 can pass through the inside of the arc-shaped through groove 503 and complete a full rotation. Before the piston 601 reaches the position at point A, the rotating gate 502 rotates again to the solid position and is located inside the circular shell 1, thereby forming a sealed space again, which is convenient for the expanding gas to push the piston 601 to rotate.

[0048] Embodiment 2

[0049] like Figure 8-Figure 12 As shown, in order to solve the existing problems, based on the same concept as the above-mentioned embodiment 1, the piston circulating rotating fuel oil or gas engine further includes a sliding gate component 9, which is used as a replacement for the rotating gate component 5. The sliding gate component 9 includes a sliding housing 902 connected to the outer arc surface of the circular shell 1, and a sliding gate 901 is slidably connected to the inner wall of the sliding housing 902. The sliding gate 901 faces the inside of the circular shell 1, and the width of the sliding gate 901 is greater than or equal to the width of the inner wall of the circular shell 1. A sealing member 903 is provided at the edge of the sliding gate 901, and the sealing member 903 contacts and squeezes the inner wall of the circular shell 1. An opening and returning device is provided at the outer top of the sliding gate 901.

[0050] The specific working principle is: the combination of the sliding gate 901 and the slope on the side of the piston connector 602 can achieve the effect of automatic opening and closing of the gate. Compared with the rotating gate component 5, it can effectively reduce the number of structural components and improve the automatic use effect of the device.

[0051] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
