Background technique

Existing internal combustion engines are mainly divided into two types. One is an internal combustion engine system that uses a reciprocating piston connecting rod to drive the flywheel to rotate. The other is an internal combustion engine system that uses an eccentrically arranged rotor and stator to rotate and compress gas or gas deflagration to push the rotor to perform work. Rotor internal combustion engine system. Since the reciprocating internal combustion engine system continuously improves the quality and speed of the crankshaft in order to achieve the air compression ratio, the engine main shaft speed is limited due to the consumption of compression energy storage, and the high-speed movement of the reciprocating piston causes large engine body vibrations.

There is also a type of internal combustion engine that uses blades to compress the space between the eccentrically arranged rotor and stator. However, the blades in this type of engine usually need to reciprocate or swing back and forth to adapt to their changing rotation paths, resulting in the failure of this part of the structure. The reliability is low and cannot be practical.

In an optional embodiment, as shown in FIGS. 7 and 8 , the first rotor 200 is provided with a pin shaft 600 groove 201 in a direction parallel to the axial direction at the position where the blade 500 passes through, and a pin shaft 600 is rotatably arranged in the pin shaft 600 groove 201, and a sliding channel 610 for the blade 500 to pass through and pass through is arranged on the pin shaft 600; the blade 500 passes through the pin shaft 600 and the first rotor 200 through the sliding channel 610 and the pin shaft 600 groove 201; when the blade 500 rotates with the first rotor 200, due to the eccentric rotation of the rotating axis of the blade 500 and the rotating axis of the first rotor 200, The blade 500 is arranged in a rotation cycle, and the angle of the blade 500 relative to the first rotor 200 will change periodically. By arranging the pin shaft 600 groove 201 and the pin shaft 600 on the first rotor 200, when the blade 500 rotates relative to the exit, the pin shaft 600 will rotate at a small angle in the pin shaft 600 groove 201, thereby improving the sealing effect of the blade 500 at the exit of the first rotor 200. At the same time, compared with other engines in the prior art, in addition to the pin shaft 600 reciprocating at a small angle, there are no other reciprocating or swinging parts in the present application, which is more suitable for high-speed engine conditions.

In an optional embodiment, as shown in Figures 3, 7, and 8, the interior of the stator 100 is an annulus with coaxial inner and outer peripheral surfaces, and the first rotor 200 is annular and eccentric. The rotation is arranged in the annulus, and the first rotor inner circumferential surface 220 and the first rotor outer circumferential surface 210 are simultaneously tangent to the stator outer circumferential surface 120 and the stator inner circumferential surface 110 respectively. At this time, the two tangent positions T of the rotor and the stator 100 180° apart, forming an inner cavity 402 and an outer cavity 401 at the same time; it also includes at least two blades 500. The first blade 510 and the second blade 520 respectively pass through the first rotor 200 and connect with the stator inner peripheral surface 110 and the stator outer peripheral surface 120. Adapt to separate the inner cavity 402 and the outer cavity 401. The coaxially arranged stator inner circumferential surface 110 and stator outer circumferential surface 120 can make the rotation axes of the first blade 510 and the second blade 520 also coaxial, which improves the coaxiality of the engine and further enhances the stability of the engine at high speeds. sex.

In an optional embodiment, the blade 500 includes a first blade 510 and a second blade 520. In this case, there are two blade shafts 530 fixedly connected to the first blade 510 and the second blade 520 respectively. The two blade shafts 530 are the same.

Therefore, when used as a combustion chamber, the angle of the blades 500 in the chamber is set to a maximum of 150°, and the remaining formation can also meet the needs of the gas in the combustion chamber. Combustion expansion drives the blades 500 to do work.

In an optional embodiment, the first blade 510 is adapted to the stator outer peripheral surface 120 to separate the inner cavity 402. However, since the first blade 510 will also partially extend into the outer cavity 401, in order to prevent the first blade from 510 seals off the outer cavity 401. As shown in Figure 8, a gap 511 can be left between the first blade 510 and the stator inner circumferential surface 110 forming the outer cavity 401, or at the end where the first blade 510 is close to the stator inner circumferential surface 110. There is a ventilation channel 512. As the blade 500 rotates, the above-mentioned gap 511 and the ventilation channel 512 will only be located in the outer cavity 401, not the inner cavity 402, and will not affect the first blade 510 to seal the inner cavity 402.

In an optional embodiment, as shown in Figure 19, the first rotor 200 is provided with a connecting groove 202, which connects the inner peripheral surface and the outer peripheral surface of the first rotor 200, and further connects the inner cavity 402 and the outer cavity 401. When the inner cavity 402 and the outer cavity 401 are used as the combustion chamber and compression chamber of the engine respectively, the connecting groove 202 can transport the compressed gas in the compression chamber to the combustion chamber, so that it can be ignited or compression ignited in the combustion chamber. The power stroke pushes the blade 500 forward.

The optional connection slot 202 and the connection port of the outer cavity 401 are located at the rear side of the second blade 520 of the first rotor 200, that is, they are connected to the chamber in the outer cavity 401 that is continuously enlarged during a stroke; when the outer cavity 401 is used as a combustion chamber, the high-pressure gas temporarily stored in the connection slot 202 will enter the outer cavity 401 through the connection port, and then be ignited or compressed to do work to push the blade 500 forward; the optional connection slot 202 and the connection port of the inner cavity 402 are located at the rear side of the first blade 510 of the first rotor 200, that is, they are connected to the chamber in the inner cavity 402 that is continuously compressed during a formation; let the inner cavity 402 be used as a compression chamber When in use, the chamber will compress the fuel gas. When the chamber is compressed to the minimum, the energy is increased to press the fuel gas into the connecting groove 202 through the connecting port, thereby increasing the compression ratio. Similarly, in a specific engine layout, when the outer chamber 401 is used as a compression chamber, the connecting port between the connecting groove 202 and the outer chamber 401 can also be located in front of the point where the second blade 520 of the first rotor 200 passes through. And when the inner chamber 402 is used for combustion, the connecting port between the connecting groove 202 and the inner chamber 402 can also be located on the rear side of the point where the first blade 510 of the first rotor 200 passes through.

In an optional embodiment, as shown in Figures 7, 8, 15, 21, and 22, the first rotor 200 has a pin 600 slot 201 along the direction parallel to the axial direction, and the pin 600 slot 201 is located on the blade 500. At the penetration point, the pin 600 is rotated in the groove 201 of the pin 600. The pin 600 is provided with a sliding channel 610 for the blade 500 to penetrate.

When the pressure in the inner chamber 402 or the outer chamber 401 is greater than the preset pressure of the one-way valve 630, the one-way valve 630 The valve 630 is opened, and the inner cavity 402 or the outer cavity 401 is connected to the connecting groove 202; when the pressure of the inner cavity 402 or the outer cavity 401 is less than the preset pressure of the one-way valve 630, the one-way valve 630 is closed. For example, when the inner chamber 402 or the outer chamber 401 is used as a compression chamber, when the high-pressure gas in the connecting groove 202 is ignited, expanded and discharged, when the inner chamber 402 or the outer chamber 401 is used as a compression chamber to compress the gas, When the pressure of the inner wall or outer cavity 401 is greater than the preset pressure of the one-way valve 630, the one-way valve 630 will be pushed open, and the compressed gas can successfully pass into the connecting groove 202 and be temporarily stored; for example When the inner cavity 402 or the outer cavity 401 is used as a combustion chamber, the gas in the inner cavity 402 or the outer cavity 401 is ignited. After the gas is ignited, it expands and generates huge pressure, which pushes the one-way valve 630 open to keep the connection groove 202 and The inner cavity 402 or the outer cavity 401 is connected, and the gas in the connecting groove 202 also undergoes combustion and expansion until exhaust, and the exhaust gas in the connected connecting groove 202 and the inner cavity 402 or the outer cavity 401 is discharged until the air pressure is less than the predetermined level. Assuming the pressure, the one-way valve 630 is closed at this time.

In an optional embodiment, a valve core 631 is slidably provided in the connecting passage 620, and the valve core 631 has two states in the connecting passage 620, as shown in Figures 9 and 10, when the valve core 631 slides to the first position A, the connecting passage 620 is opened, and when the valve core 631 slides to the second position B, the connecting passage 620 is closed; and one end of the connecting passage 620 is connected to the inner cavity 402 or the outer cavity 401 to enable the high-pressure fluid in the inner cavity 402 or the outer cavity 401 to push the valve core 631 to slide toward the first position A, and an elastic member 632 is also provided in the connecting passage 620 to push the valve core 631 to reset to the second position B. At this time, the elastic force generated by the elastic member 632 is the preset pressure, that is, when the pressure in the inner cavity 402 or the outer cavity 401 is greater than the elastic force of the elastic member 632, the valve core 631 can be pushed to slide to the second position B and open the connecting passage 620.

In an optional embodiment, the sliding direction of the valve core 631 and the action direction of the high-pressure fluid in the connecting groove 202 are set non-collinearly, so that the sliding direction of the valve core 631 is not affected by the pressure of the fluid in the connecting groove 202. No matter the pressure is high or low, it will not affect the sliding of the valve core 631, so that the sliding of the valve core 631 is only affected by the elastic member 632 and the pressure in the inner cavity 402 or the outer cavity 401. The preferred sliding direction of the valve core 631 is consistent with the pressure in the connecting groove 202. The included angle to the action direction of the valve core 631 is 90° to completely eliminate the influence of the pressure in the connecting groove 202 on it.

In an optional embodiment, as shown in Figures 12-17, an opening position C is provided on the blade 500 or the side end surface 130 of the stator 100, so that when the pin 600 slides to this position, it can be opened at this position. Valve core 631, since the valve core 631 provided in the pin 600 is a one-way valve 630, the valve core 631 cannot be opened except by the pressure of the inner chamber 402 or the outer chamber 401. The setting of the opening position C makes the valve core 631 slide. When the blade 500 rotates to a specific position or a specific angle, the valve core 631 can be opened. For example, when the inner cavity 402 or the outer cavity 401 is used as a combustion chamber, when the blade 500 rotates to a specific angle, the valve core 631 can be opened. The relative movement to the opening position C actively opens the connecting passage 620 in the pin 600. At this time, the high-pressure gas in the connecting groove 202 is connected to the inner cavity 402 or the outer cavity 401. After being further ignited and compression ignited, the high-pressure gas further expands. , while performing work, the pressure of the inner chamber 402 or the outer chamber 401 is maintained, and the valve core 631 is kept open, so that the connecting groove 202 remains connected to the inner chamber 402 or the outer chamber 401. During the next exhaust formation, the connecting groove is synchronously opened. 202. Exhaust gas in the inner cavity 402 or the outer cavity 401 is discharged.

For example, when the opening position C is provided on the side end surface 130 of the blade 500 or the stator 100 and the pin 600 slides to the opening position C, the valve core 631 slides to the first position A to open the connection passage 620 .

For example, the opening position C is located at the end or root of the blade 500, or the opening position C is located at the tangent position T between the stator 100 and the first rotor 200. When the first rotor 200 rotates to the tangent position T, the pin 600 will Sliding relative to the blade 500, the pin 600 will slide to the end or root of the blade 500. The opening position C is set here, so that when the blade 500 crosses the tangent position and enters the next rotation cycle, the valve body in the pin 600 The connecting passage 620 can be connected through the opening position C to smoothly transport the high-pressure gas in the connecting groove 202 to the inner cavity 402 or the outer cavity 401 used as a combustion chamber.

In an optional embodiment, as shown in FIGS. 12 and 13 , a connecting branch 640 is provided on the contact surface between the pin 600 and the blade 500 or between the pin 600 and the side end surface 130 of the stator 100 . Both ends of the path 640 are connected to the connecting groove 202 and the inner cavity 402 or the outer cavity 401 respectively. When the pin 600 slides to the open position C, the connecting branch 640 is conductive. For example, the connecting branch 640 includes a component provided on the pin 600 The first branch 641 and the second branch 642 provided on the side end surface 130 of the blade 500 or the stator 100, the first branch 641 communicates with the connecting groove 202, and the second branch 642 communicates with the inner cavity 402 or the outer cavity 401. When When the pin 600 slides to the open position C, the first branch 641 and the second branch 642 are aligned, allowing the high-pressure gas in the connecting groove 202 to pass into the inner cavity 402 or the outer cavity 401, and open the valve core 631 to keep the valve body open. , the connection path 620 is conductive; when the pin 600 does not slide to the opening position C, the connection branch 640 is not conductive. For example, the first branch 641 and the second branch 642 are misaligned, and the connection branch 640 is disconnected. .

In an optional embodiment, as shown in Figures 16 and 17, a wedge 650 is provided on the side end surface 130 of the blade 500 or the stator 100. The wedge 650 is located in the open position C. When the pin 600 slides along the blade 500 When it reaches the opening position C, it will interact with the wedge 650, causing the valve core 631 to be pushed by the wedge 650 and move to the first position A.

The working cycle of a twin engine proposed in the embodiment of the present invention will be described below with reference to the accompanying drawings:

Please refer to Figures 7-23. The engine includes a stator 100. An annulus, a stator inner circumferential surface 110 and a stator outer circumferential surface 120 are formed in the stator 100. A first rotor 200 is rotated in the stator 100. The first rotor 200 is annular. , the first rotor outer peripheral surface 210 is tangent to the stator inner peripheral surface 110 and enclosed to form an outer cavity 401, and the outer cavity 401 is a combustion chamber;

Two blade shafts 530 are also rotatably provided on the outer circumferential surface of the stator 100. The two blade shafts 530 are fixedly connected to the first blade 510 and the second blade 520 respectively. The included angle between the two blades 500 is 180°. The outer circumferential surface of the shaft 530 is tangent to the inner circumferential surface of the first rotor 200 and is enclosed to form an inner cavity 402. The inner cavity 402 is a compression chamber. A connecting groove 202 is provided in the first rotor 200 to communicate with the inner and outer cavities 401 respectively. The inner cavity 402 is a compression chamber. One blade 510 passes through the first rotor 200 and contacts the stator outer peripheral surface 120 to separate the outer cavity 401. After the second blade 520 passes through the first rotor 200, there is a gap 511 with the stator outer peripheral surface 120 to separate the inner cavity 402. while not affecting the communication of the outer cavity 401;

The first blade 510 goes out of the first rotor 200 through the first pin 600a, and the second blade 520 goes out of the first rotor 200 through the second pin 600b. The first valve core 631a and the first valve core 631a are disposed in the first pin 600a. The elastic member 632a and the second pin 600b are provided with a second valve core 631b and a second elastic member 632b. The connecting groove 202 is connected to the outer cavity 401 through the first pin 600a, and the connecting groove 202 is connected to the inner cavity through the second pin 600b. Cavity 402, when the pressure of the outer cavity 401 is greater than the first elastic member 632a, the first pin 600a opens, when the pressure of the inner cavity 402 is greater than the second elastic member 632b, the second pin 600b opens, and the second pin 600b is also provided with The branch 640 is connected to the opening position C. The opening position C is located at the outer end of the second blade 520 .

An air inlet 103 is also provided inside the inner circumferential surface 110 of the stator. An air inlet loop 531 connected with the air inlet 103 is provided circumferentially inside the blade shaft 530. An air inlet 532 is opened on the blade shaft 530. The air intake loop 531 is connected, and the air suction port 532 is located on the rear side of the second blade 520; an ignition device 105 is provided on the front side of the stator inner peripheral surface 110 and the first rotor 200, and an exhaust device is provided on the rear side.

Next, the first blade 510 passes over the tangential position T between the blade shaft 530 in the inner cavity 402 and the first rotor 200 as the starting point, and at the same time, the second blade 520 passes over the tangential position T between the inner surface of the stator 100 in the outer cavity 401 and the first rotor 200 . Taking the starting point rotation as an example, the working principle of the engine in this embodiment is introduced:

As shown in Figure 20, when the first blade 510 crosses the tangent position T (example rotation of 30°), the rear side of the first blade 510 forms a suction chamber α, and the suction chamber α is formed through the rear side of the first blade 510. The port 532 inhales gas through the air inlet loop 531 and the air inlet 103 in sequence; a compression chamber β is formed on the front side of the first blade 510 to compress the gas inhaled in the previous cycle, see Figure 19 .

As shown in Figure 22, when the first blade 510 rotates once to approach the tangent position T (an exemplary rotation of 335°), the suction chamber α on the rear side of the first blade 510 completes the inhalation of gas, and the first blade The compression chamber β on the front side of 510 compresses the smoke inhaled in the previous cycle. At this time, the compression chamber β on the front side of the first blade 510 acts on the first valve core 631a in the first pin 600a to compress the first elasticity. The member 632a is connected to the connection passage 620 to connect the connection groove 202 and the compression chamber β, so that the high-pressure gas enters the connection groove 202 of the first rotor 200.

As shown in Figure 20, when the second blade 520 crosses the tangent position T (example rotation of 30°), the front side of the second blade 520 piece 510 forms an exhaust cavity δ. During the subsequent rotation, The combustion exhaust gas of the previous cycle is discharged through the exhaust port 106, and a power chamber γ is formed on the rear side of the second blade 5200. At this time, the second pin 600b will slide relative to the second blade 520 until the second blade 520 is connected to the inner circumference of the stator. The acting end of the surface 110 slides to the open position C. The high-pressure gas in the connecting groove 202 will enter the power chamber γ through the connecting branch 640 and compress the second elastic member 632b to maintain the connecting path of the second pin 600b. 620 is turned on, and during the subsequent rotation process, the gas in the power chamber γ and the connecting groove 202 will be ignited, and then the second blade 520 will be pushed to rotate to perform power.

As shown in FIG. 21 , when the second blade 520 rotates to pass over the exhaust port 106 (exemplarily rotating 340°), the working chamber γ is connected to the exhaust port 106. At this time, the working chamber γ and the connecting groove 202 are instantly connected to the outside world, and the high-pressure gas is discharged synchronously. During the discharge process, since the connecting passage 620 in the second pin shaft 600b remains open, the air pressure in the working chamber γ and the connecting groove 202 will decrease synchronously. When the air pressure drops to less than the preset elastic force of the second elastic member 632b, the second elastic member 632b pushes the second valve core 631b to close the connecting passage 620, thereby ending the connection between the connecting groove 202 and the outer chamber 401, so that the connecting groove 202 can be connected to the compression chamber of the inner chamber 402 in the next stage to supplement the high-pressure gas, as shown in FIGS. 22 and 23 .

Through the above working principle, a double cycle of compression and power is realized during the 360° rotation of the first rotor 200 .

For example, the fuel used in the present invention is not fixed, but is adjusted according to the usage scenario, such as using gasoline, diesel, kerosene, alcohol, various flammable gases and liquids from time to time as fuel. For diesel with poor air handling ability, you can also add a heating device to preheat the diesel until it reaches the boiling point, then adjust it through the throttle and mix it with air before entering the compression cycle.

The size of each structural part in the present invention is not fixed, but can be made larger or smaller according to the usage scenario. For example, the minimum is 1 square centimeter, and the maximum exhaust volume can be 100 million cubic meters.

The application in the present invention is not only limited to outputting the torque of the first rotor 200, the second rotor 300 or the blade shaft 530 through the output shaft, but also includes exhausting exhaust gas to output thrust through the exhaust port 106. The torque output and displacement can also be changed by adjusting the rotation period. At the same time, the torque output can be used in all torque situations, and the jet output is not limited to the use of aircraft.
