Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Related technologies have proposed rotary engines, which use rotary motion instead of reciprocating motion, resulting in a more compact structure and higher rotational speed. For example, a dual-wheel rotor engine provided in related technologies employs a cam and concave wheel dual-wheel structure.

[0023] The cam has a single tooth that acts as a piston, and the concave wheel has a groove; the two wheels rotate synchronously. The single tooth rotates within the annular cylinder, and the concave wheel divides the cylinder into a combustion chamber and an exhaust chamber. High-pressure air and fuel are injected directly into the combustion chamber through the intake port. After ignition, the combustion gases drive the single tooth to rotate and perform work, while simultaneously compressing and expelling the exhaust gases in front of the single tooth. After the single tooth passes the groove, a new combustion chamber is formed, and the cycle of intake, combustion, and exhaust continues.

[0024] This engine eliminates the compression stroke, relying on an external compressor to provide high-pressure air. The engine itself does not compress the combustion gases; it depends entirely on the compressor for air pressure and requires a controllable air pressure output device. If the compressor malfunctions or the air pressure control fails, the engine will not operate, and its reliability needs improvement.

[0025] Therefore, the purpose of this invention is to provide a novel rotary engine and vehicle.

[0026] The following is combined Figures 1 to 19 This describes the rotary engine provided in an embodiment of the present invention.

[0027] Specifically, the rotary engine includes a housing 1, a power wheel 2, a first air intake 3, and auxiliary components 4.

[0028] The housing 1 has an annular cavity 101, which has an exhaust port 103, an air inlet 102, a compression port 104 and a combustion port 105, and the compression port 104 and the combustion port 105 are connected to each other.

[0029] Understandably, the intake port 102 is connected to the throttle valve 9 for intake. The exhaust port 103 is used for exhaust. The compression port 104 is connected to the combustion port 105 for transferring compressed gas to the combustion port 105. The connection referred to here can be a flow channel 110 provided on the housing 1, through which structures requiring connection are connected, or it can be an external pipeline connecting the two required structures.

[0030] The power wheel 2 is rotatably disposed within the annular cavity 101, and its inner and outer walls are respectively provided with a first protrusion 201 and a second protrusion 202. That is, the inner wall of the power wheel 2 is provided with the first protrusion 201, and the outer wall of the power wheel 2 is provided with the second protrusion 202. The inner wall of the power wheel 2 is spaced from the inner annular wall of the annular cavity 101, the first protrusion 201 is in contact with the inner annular wall of the annular cavity 101, the outer wall of the power wheel 2 is spaced from the outer annular wall of the annular cavity 101, and the second protrusion 202 is in contact with the outer annular wall of the annular cavity 101.

[0031] refer to Figure 3 and Figure 4 As shown, the first air intake 3 is disposed inside the power wheel 2, and the first air intake 3, together with the first protrusion 201, separates the inner space of the power wheel 2 into a first air intake chamber a and a first compression chamber b. The first air intake chamber a is used to arrange the air inlet 102, and the first compression chamber b is used to arrange the compression port 104. The inner space of the power wheel 2 is the annular space between the power wheel 2 and the inner annular wall of the annular cavity 101.

[0032] For example, the contact point between the first protrusion 201 and the inner wall of the annular cavity 101 and the contact point between the first air intake 3 and the inner wall of the power wheel 2 divides the annular space inside the power wheel 2 into a first air intake chamber a and a first compression chamber b. It can be understood that the volumes of the first air intake chamber a and the first compression chamber b can change periodically as the power wheel 2 rotates.

[0033] The auxiliary component 4 is located on the outside of the power wheel 2, and together with the second protrusion 202, it separates the outer space of the power wheel 2 into a first combustion chamber c and a first exhaust chamber d. The first combustion chamber c is used to house the combustion port 105, and the first exhaust chamber d is used to house the exhaust port 103. The first combustion chamber c increases synchronously with the first intake chamber a; that is, as the power wheel 2 rotates, the volume of the first intake chamber a increases, and the volume of the first combustion chamber c also increases. The outer space of the power wheel 2 is the annular space between the power wheel 2 and the outer annular wall of the annular cavity 101.

[0034] For example, the contact point between the second protrusion 202 and the outer ring wall of the annular cavity 101 and the contact point between the auxiliary component 4 and the outer wall of the power wheel 2 divides the annular space outside the power wheel 2 into a first combustion chamber c and a first exhaust chamber d. It can be understood that the volumes of the first combustion chamber c and the first exhaust chamber d can change periodically as the power wheel 2 rotates.

[0035] The combustion port 105 remains closed to prevent gas from the first compression chamber b from entering the first combustion chamber c during compression. Simultaneously, the combustion port 105 opens when the first protrusion 201 reaches a preset position, allowing gas from the first compression chamber b to enter the first combustion chamber c after compression is complete. For example, the combustion port 105 opens when the first protrusion 201 approaches, reaches, or crosses the compression port 104.

[0036] Specifically, the moment when the first protrusion 201 approaches the compression port 104 can be understood as the moment when the first protrusion 201 is about to arrive but has not yet arrived; the moment when the first protrusion 201 reaches the compression port 104 can be understood as the moment when the first protrusion 201 and the compression port 104 at least partially overlap; and the moment when the first protrusion 201 crosses the compression port 104 can be understood as the moment when the first protrusion 201 has separated from the compression port 104.

[0037] It can be understood that when the first protrusion 201 approaches, reaches or crosses the compression port 104, that is, when the corresponding compression stroke ends, in specific applications, the appropriate time can be selected as the time when the compression stroke ends according to the actual compression requirements, and there is no limitation on this.

[0038] In this embodiment, reference is made to Figure 3 As shown, as the power wheel 2 rotates counterclockwise around the diagram, the volume of the first intake chamber a increases, allowing gas to be drawn in through the intake port 102, corresponding to the engine's intake stroke. Simultaneously, the volume of the first compression chamber b decreases, compressing the gas drawn in during the previous cycle, corresponding to the engine's compression stroke.

[0039] Because the combustion port 105 is closed before the end of the compression stroke, the gas cannot enter the first combustion chamber c and can only be compressed. At the end of the compression stroke, the combustion port 105 opens, allowing the compressed gas to enter the first combustion chamber c. After the combustion port 105 is closed again, the gas can be ignited, thereby driving the power wheel 2 to rotate, corresponding to the engine's power stroke. The gas can be ignited by compression ignition or by ignition by the igniter 5.

[0040] At the same time, the volume of the first exhaust chamber d decreases, thereby enabling the combustion exhaust gases generated in the previous cycle to be discharged from the exhaust port 103, corresponding to the exhaust stroke of the engine.

[0041] During the power stroke, the intake stroke, compression stroke, and exhaust stroke can run simultaneously.

[0042] In summary, by cooperating with the power wheel 2 and the first intake component 3, the present invention can autonomously compress the intake gas when the volume of the first compression chamber b inside the power wheel 2 decreases as the power wheel 2 rotates. The entire compression process does not require the intervention of external equipment, which can eliminate the dependence on external compressors, thereby reducing the number of engine parts and improving operational reliability.

[0043] Furthermore, by dividing the inner and outer spaces of the power wheel 2 into sections through the first protrusion 201, the second protrusion 202, the first intake component 3, and the auxiliary component 4, the parallel operation of the four strokes of "intake, compression, power, and exhaust" can be achieved, thereby improving the energy conversion efficiency of the engine per unit time.

[0044] In addition, when one power stroke ends, the next compression stroke has already been completed, and a new power stroke begins immediately. This shortens the power gap during stroke switching compared to a reciprocating engine, resulting in smoother power output.

[0045] refer to Figure 8 and Figure 9 As shown, in some embodiments provided by the present invention, the interior of the housing 1 is provided with a boss 111, and an annular cavity 101 is formed between the outer periphery of the boss 111 and the inner wall of the housing 1. The interior of the boss 111 is hollow, and the power wheel 2 is fitted on the outer side of the boss 111.

[0046] In this embodiment, the boss 111 can be used to form an annular cavity 101. In addition, the hollow design can significantly reduce the overall weight of the engine, thereby improving the energy efficiency of the vehicle or equipment. For example, a lighter engine not only helps to improve fuel economy, but may also improve the power performance and handling of the vehicle.

[0047] In addition, the hollow part of the boss 111 can be used to introduce a cooling medium (such as coolant or cooling air). Through the heat conduction between the boss 111 and the annular cavity 101, the heat transferred from the combustion chamber to the boss 111 is directly carried away, resulting in a shorter cooling path and higher cooling efficiency.

[0048] refer to Figure 3 and Figure 4 As shown, in some embodiments provided by the present invention, the first air intake 3 is rotatably disposed inside the power wheel 2 and contacts the inner circumference of the power wheel 2, that is, the outer circumference of the first air intake 3 contacts the inner circumference of the power wheel 2. The outer circumference of the first air intake 3 is provided with a first recess 301 for avoiding the first protrusion 201, so that when the first protrusion 201 rotates to the position of the first air intake 3, it can be embedded in the first recess 301.

[0049] In this embodiment, the state in which the first protrusion 201 is embedded in the first recess 301 can be understood as the state in which the volume of the first intake chamber a is the smallest and the volume of the first compression chamber b is the largest, or it can be understood as the state in which the volume of the first intake chamber a is the largest and the volume of the first compression chamber b is the smallest. After the first protrusion 201 disengages from the first recess 301, as the power wheel 2 rotates, the volume of the first intake chamber a gradually increases to draw in gas, while the volume of the first compression chamber b gradually decreases to compress the gas.

[0050] In addition, when the first protrusion 201 moves to the position of the first air intake 3, the first protrusion 201 is embedded in the first recess 301, so that the first protrusion 201 can pass over the first air intake 3 through the avoidance action of the first recess 301. That is, the first air intake 3 can not only form the first air intake chamber a and the first compression chamber b together with the first protrusion 201, but also avoid the first protrusion 201 during the rotation of the first protrusion 201, so as to ensure the stable operation of the system.

[0051] Optionally, such as Figure 5 and Figure 9 As shown, the boss 111 on the inner side of the annular cavity 101 is provided with a receiving cavity for accommodating the first air intake component 3, and the receiving cavity penetrates the outer peripheral wall of the boss 111. A support shaft 112 is provided inside the receiving cavity, and the first air intake component 3 is fitted onto the support shaft 112 and protrudes from the outer peripheral wall of the boss 111. The part of the first air intake component 3 protruding from the boss 111 contacts the inner periphery of the power wheel 2.

[0052] In this embodiment, the receiving cavity in the boss 111 penetrates the outer peripheral wall of the boss 111, so that the first air intake 3 can partially extend into the annular cavity 101 and directly contact the power wheel 2, thereby enabling the first air intake 3 to effectively interact with the power wheel 2 and realize the functions of gas intake and compression.

[0053] In addition, the receiving cavity is located inside the boss 111, allowing the first air intake 3 to be partially embedded inside the boss 111, while maintaining necessary contact with the power wheel 2, thereby effectively utilizing space and making the overall design more compact and efficient.

[0054] It is understood that the avoidance of the first protrusion 201 is not limited to rotating the first air intake member 3. For example, in some embodiments not shown, the first protrusion 201 is slidably disposed on the power wheel 2 along the radial direction of the power wheel 2. When the first protrusion 201 moves to the position of the first air intake member 3, the first air intake member 3 can drive the first protrusion 201 to slide, thereby avoiding the first air intake member 3. Furthermore, an elastic member can be provided to reset the first protrusion 201.

[0055] Similarly, it is not limited to moving the first protrusion 201 radially. For example, in some embodiments not shown, the first air intake 3 is slidably mounted on the boss 111 along the radial direction of the power wheel 2. When the first protrusion 201 moves to the position of the first air intake 3, the first protrusion 201 can drive the first air intake 3 to slide so that the first air intake 3 avoids the first protrusion 201.

[0056] In some embodiments provided by the present invention, the first air intake 3 is connected to the power wheel 2 in a transmission connection so that the power wheel 2 can drive the first air intake 3 to rotate.

[0057] In this embodiment, since the first air intake member 3 and the first protrusion 201 together separate the first air intake chamber a and the first compression chamber b, their relative positions directly determine the rhythm of the cavity volume change. The transmission connection in this embodiment can forcibly limit the rotation phase of the two. For example, when the power wheel 2 rotates a certain angle, the first air intake member 3 rotates synchronously at the corresponding angle, ensuring that the moment when the first protrusion 201 is inserted into or removed from the first recess 301, and the rate of change of the air intake chamber or compression chamber volume, meet the design expectations.

[0058] Optionally, refer to Figure 3 As shown, an internal gear ring is provided on the inner circumference of the power wheel 2, and an external gear ring is provided on the outer circumference of the first air intake component 3. The internal gear ring and the external gear ring mesh with each other.

[0059] In this embodiment, the meshing of the internal gear ring and the external gear ring constitutes a rigid gear transmission structure, which can ensure that the power wheel 2 and the first air intake 3 rotate synchronously with a precise speed ratio, effectively preventing relative slippage and ensuring that the first air intake 3 always follows the rotation of the power wheel 2 according to a predetermined phase, so that the timing of the engagement of the first recess 301 and the first protrusion 201, and the rhythm of volume change of the air intake chamber and the compression chamber are always consistent with the design.

[0060] In addition, the meshing part of the internal gear ring and the external gear ring can not only transmit power and ensure synchronous rotation, but also form a sealed boundary through the tight fit of the tooth surfaces, dividing the inner space of the power wheel 2 into the first intake chamber a and the first compression chamber b. No additional partition is required, so that the limited space can be used to the fullest extent and meet the requirements of engine compactness.

[0061] It is understood that the power wheel 2 and the first intake component 3 are not limited to transmission via meshing of an internal and external gear ring. For example, in some embodiments not shown, the pivot 7 of the power wheel 2 and the support shaft 112 of the first intake component 3 extend outside the chamber where the power wheel 2 is located, and the portions of the pivot 7 and the support shaft 112 extending outside the chamber can be connected by chain drive, belt drive, or gear drive. This external transmission method offers greater spatial adaptability and simplifies maintenance.

[0062] In addition, the first air intake 3 is not limited to being driven by the power wheel 2. For example, in other embodiments not shown, the first air intake 3 can be driven to rotate by an additional motor, for example, the output shaft of the motor is connected to the support shaft 112 of the first air intake 3.

[0063] refer to Figure 3 and Figure 4 As shown, in some embodiments provided by the present invention, the housing 1 further includes an auxiliary cavity 106, which is located outside the annular cavity 101 and communicates with the annular cavity 101. The auxiliary member 4 is rotatably disposed in the auxiliary cavity 106 and contacts the outer periphery of the power wheel 2. The outer periphery of the auxiliary member 4 is provided with a second recess 401 for avoiding the second protrusion 202.

[0064] In this embodiment, the state in which the second protrusion 202 is embedded in the first recess 301 can be understood as the state in which the volume of the first combustion chamber c is at its minimum and the volume of the first exhaust chamber d is at its maximum, or it can be understood as the state in which the volume of the first combustion chamber c is at its maximum and the volume of the first exhaust chamber d is at its minimum. After the second protrusion 202 disengages from the first recess 301, as the power wheel 2 rotates, the volume of the first combustion chamber c gradually increases to perform work, while the volume of the first exhaust chamber d gradually decreases to discharge combustion exhaust gases.

[0065] In addition, when the second protrusion 202 moves to the position of the auxiliary member 4, the second protrusion 202 is embedded in the second recess 401, so that the second protrusion 202 can pass over the auxiliary member 4 through the avoidance action of the second recess 401. That is, the auxiliary member 4 can not only form the first combustion chamber c and the first exhaust chamber d together with the second protrusion 202, but also avoid the second protrusion 202 during the rotation of the second protrusion 202, so as to ensure the stable operation of the system.

[0066] It is understood that the avoidance of the second protrusion 202 is not limited to rotating the auxiliary member 4. For example, in some embodiments not shown, the second protrusion 202 is slidably disposed on the working wheel 2 along the radial direction of the working wheel 2. When the second protrusion 202 moves to the position of the auxiliary member 4, the auxiliary member 4 can drive the second protrusion 202 to slide in order to avoid the auxiliary member 4. Furthermore, an elastic member can be provided to reset the second protrusion 202.

[0067] Similarly, it is not limited to moving the second protrusion 202 radially. For example, in some embodiments not shown, the auxiliary member 4 is slidably mounted in the auxiliary cavity 106 radially along the working wheel 2. When the second protrusion 202 moves to the position of the auxiliary member 4, the second protrusion 202 can drive the auxiliary member 4 to slide so that the auxiliary member 4 avoids the second protrusion 202.

[0068] In some embodiments provided by the present invention, the auxiliary component 4 is connected to the working wheel 2 in a transmission connection so that the working wheel 2 can drive the auxiliary component 4 to rotate.

[0069] Since the auxiliary component 4 and the second protrusion 202 together separate the first combustion chamber c and the first exhaust chamber d, their relative positions directly determine the rhythm of the cavity volume change. The transmission connection in this embodiment can forcibly limit the rotation phase of the two components. For example, when the power wheel 2 rotates at a certain angle, the auxiliary component 4 rotates at the corresponding angle, ensuring that the moment when the second protrusion 202 is inserted into or removed from the second recess 401, and the rate of change of the intake chamber or compression chamber volume, meet the design expectations.

[0070] refer to Figure 11 and Figure 12 As shown, optionally, the power wheel 2 has a ring-shaped structure, and the rotary engine also includes a support plate 6 and a pivot 7. The support plate 6 is connected to one end of the power wheel 2 and closes the port of one end of the power wheel 2, for example, the two can be screwed or welded together. The other end of the power wheel 2 is fitted against the inner wall of the housing 1, and the housing 1 closes the port of the other end of the power wheel 2. Correspondingly, both ends of the first air intake 3 are fitted against the support plate 6 and the inner wall of the housing 1, respectively.

[0071] Furthermore, the pivot 7 passes through both sides of the support plate 6 and is welded or screwed to the support plate 6. Both ends of the pivot 7 are rotatably connected to the housing 1. It is understood that the auxiliary component 4 can adopt a structure similar to that of the power wheel 2 and be rotatably connected to the housing 1.

[0072] In this embodiment, the power wheel 2 adopts an annular structure, with one end closed by the support plate 6 and the other end fitting against the inner wall of the housing 1, forming a completely closed annular space and ensuring that gas will not leak axially. In addition, both ends of the pivot 7 are supported by the housing 1, which can avoid vibration or deformation caused by torque fluctuations, thereby providing stable rotational support for the power wheel 2 and ensuring stability during power output.

[0073] refer to Figure 1 , Figure 8 , Figure 13 and Figure 14 As shown, in some embodiments provided by the present invention, the housing 1 includes a first housing 107, a second housing 108, and an end cap 109. The first housing 107, the second housing 108, and the end cap 109 are arranged sequentially and connected, wherein the second housing 108 closes the opening of the first housing 107, and the end cap 109 closes the opening of the second housing 108.

[0074] Furthermore, the annular cavity 101 and the auxiliary cavity 106 are disposed within the first housing 107. A support plate 6 is provided at one end of the power wheel 2 near the second housing 108, and the end of the power wheel 2 away from the second housing 108 is fitted against the inner wall of the first housing 107. One end of the pivot 7 passes through the second housing 108 and is rotatably connected to the second housing 108, while the other end of the pivot 7 is rotatably connected to the first housing 107.

[0075] Similarly, one end of the pivot 7 of the auxiliary component 4 passes through the second housing 108 and is rotatably connected to the second housing 108, while the other end is rotatably connected to the first housing 107. Both the portion of the pivot 7 of the auxiliary component 4 that passes through the second housing 108 and the portion of the output shaft of the power wheel 2 that passes through the second housing 108 are provided with synchronous gears 8, and the synchronous gears 8 of the two are meshed.

[0076] In this embodiment, the auxiliary component 4 and the power wheel 2 can transmit power through the meshing of the synchronous gear 8, thereby precisely fixing the speed ratio between the two and ensuring that the rotation phase of the auxiliary component 4 and the power wheel 2 strictly corresponds. For example, when the second protrusion 202 of the power wheel 2 rotates to the position of the auxiliary component 4, the second recess 401 of the auxiliary component 4 can be precisely engaged.

[0077] In addition, the end cap 109 is detachable to facilitate the inspection and maintenance of the synchronizing gear 8 inside the second housing 108.

[0078] It is understandable that the pivot 7 of the auxiliary component 4 and the pivot 7 of the power wheel 2 are not limited to gear meshing transmission. For example, the two pivots 7 can also be connected by chain transmission or belt transmission.

[0079] It is understood that the auxiliary component 4 and the power wheel 2 are not limited to a transmission connection via pivot 7, for example, refer to Figure 15 As shown, in some embodiments of the present invention, a first toothed ring is provided on the outer periphery of the power wheel 2, and the first toothed ring is located at the end of the power wheel 2 opposite to the opening of the first housing 107. Correspondingly, a second toothed ring is provided at the end of the auxiliary member 4 near the first toothed ring, and the first toothed ring and the second toothed ring mesh with each other. The number of teeth on the first toothed ring and the second toothed ring may be equal or unequal.

[0080] In this embodiment, the first gear ring and the second gear ring mesh in the same radial plane, requiring no additional axial space, which makes the overall axial dimensions of the engine more compact.

[0081] Furthermore, the power wheel 2 is not limited to being connected to the housing 1 via the pivot 7. For example, in some embodiments not shown, both ends of the power wheel 2 are provided with annular protrusions, and the inner walls of opposite sides of the housing 1 are provided with annular grooves, with the annular protrusions at both ends of the power wheel 2 rotatably disposed in the two annular grooves respectively.

[0082] Specifically, since there is no need to set a synchronizing gear 8, the second housing 108 can be omitted, and the opening of the first housing 107 can be directly closed by the end cover 109. That is, the first housing 107 and the end cover 109 are respectively provided with annular grooves, and the annular protrusions at both ends of the power wheel 2 are rotatably set in the annular grooves of the first housing 107 and the end cover 109 respectively.

[0083] Correspondingly, the auxiliary component 4 can also be rotatably installed inside the housing 1 in a manner similar to that of the power wheel 2.

[0084] In this embodiment, the power wheel 2 and the auxiliary component 4 can be directly rotatably connected to the housing 1 through the corresponding annular protrusion, thereby reducing the number of parts. In addition, the axial space of the power wheel 2 and the auxiliary component 4 can be shortened, making the overall axial dimension of the engine more compact.

[0085] refer to Figure 3 , Figures 8-10 and Figure 15 As shown, in some embodiments of the present invention, the auxiliary cavity 106 is an annular structure, and the auxiliary member 4 is rotatably disposed in the auxiliary cavity 106, therefore the auxiliary member 4 is also an annular structure. The inner wall of the auxiliary member 4 is provided with a third protrusion 402, which can contact the inner annular wall of the auxiliary cavity 106.

[0086] Accordingly, the rotary engine also includes a second air intake (not shown in the figure). The second air intake is located inside the auxiliary member 4 and, together with the third protrusion 402, separates the inner space of the auxiliary member 4 into a second air intake chamber and a second compression chamber. That is, the second air intake, together with the third protrusion 402, separates the annular space inside the auxiliary member 4 into a second air intake chamber and a second compression chamber.

[0087] The second intake chamber is used to house the air inlet 102, and the second compression chamber is used to house the compression inlet 104. The arrangement of the second intake component can be completely the same as that of the first intake component 3, and will not be described in detail here.

[0088] Further, refer to Figure 10 As shown, the air intake ports 102 of both the first intake chamber a and the second intake chamber are connected to the throttle valve 9. For example, the air intake ports 102 of both chambers are connected to the throttle valve 9. The compression ports 104 of both the first compression chamber b and the second compression chamber are connected to the combustion port 105. For example, the compression ports 104 of both chambers are connected to the combustion port 105.

[0089] In this embodiment, when the auxiliary component 4 rotates, the second air intake component and the third protrusion 402 work together to increase the volume of the second air intake chamber, thereby drawing in gas through the air intake port 102. At the same time, the first air intake component 3 of the power wheel 2 also performs the corresponding air intake operation.

[0090] As the auxiliary component 4 rotates, the volume of the second compression chamber decreases, compressing the gas within. Similarly, the first compression chamber b of the power wheel 2 is also undergoing compression. The compression ports 104 of these two compression chambers are connected to the combustion port 105, ensuring that the compressed gas can enter the combustion chamber efficiently.

[0091] In this embodiment, the coordinated operation of the first air intake component 3 and the second air intake component can achieve a more efficient air intake and compression process, thereby improving overall efficiency.

[0092] refer to Figure 3 , Figures 8-10 and Figure 15 As shown, in some embodiments provided by the present invention, the outer wall of the auxiliary component 4 is provided with a fourth protrusion 403. The fourth protrusion 403 and the power wheel 2 can separate the outer space of the auxiliary component 4 into a second combustion chamber and a second exhaust chamber. That is, the fourth protrusion 403 and the power wheel 2 can separate the annular space on the outer side of the auxiliary component 4 into a second combustion chamber and a second exhaust chamber.

[0093] The second combustion chamber is connected to the first combustion chamber c, and the second exhaust chamber is connected to the first exhaust chamber d. The outer periphery of the power wheel 2 is provided with a fourth recess 203 to avoid the fourth protrusion 403.

[0094] In this embodiment, when the power wheel 2 rotates, the fourth protrusion 403 enters or leaves the fourth recess 203, thereby dynamically changing the volume of the second combustion chamber and the second exhaust chamber. The second combustion chamber is connected to the first combustion chamber c, so that the compressed gas can be ignited and burned simultaneously in both combustion chambers, generating power to drive the power wheel 2 and the auxiliary component 4 to continue rotating.

[0095] As the auxiliary component 4 continues to rotate, the fourth protrusion 403 gradually reduces the volume of the second exhaust chamber, thereby discharging the exhaust gas after combustion. The second exhaust chamber is connected to the first exhaust chamber d, ensuring that the exhaust gas after combustion can be discharged uniformly, thus improving exhaust efficiency.

[0096] In this embodiment, the second combustion chamber is connected to the first combustion chamber c, making the combustion process more uniform and efficient, thereby improving combustion efficiency and power output. The second exhaust chamber is connected to the first exhaust chamber d, which simplifies the exhaust path, reduces exhaust resistance, and improves overall exhaust efficiency. Furthermore, the power wheel 2 and the auxiliary component 4 can output power individually or jointly, thus adapting to a wider range of application scenarios.

[0097] Of course, the two embodiments described above can also be combined. Specifically, the auxiliary cavity 106 has an annular structure, and the auxiliary component 4 is rotatably disposed in the auxiliary cavity 106, so the auxiliary component 4 also has an annular structure. The inner wall of the auxiliary component 4 is provided with a third protrusion 402, and the outer wall is provided with a fourth protrusion 403. The third protrusion 402 can contact the inner annular wall of the auxiliary cavity 106, and the fourth protrusion 403 can contact the outer annular wall of the auxiliary cavity 106.

[0098] Accordingly, the rotary engine also includes a second air intake (not shown in the figure). The second air intake is located inside the auxiliary member 4 and, together with the third protrusion 402, separates the inner space of the auxiliary member 4 into a second air intake chamber and a second compression chamber. The second air intake chamber is used to house the air inlet 102, and the second compression chamber is used to house the compression outlet 104. The arrangement of the second air intake can be completely the same as that of the first air intake 3, and will not be described further.

[0099] Further, refer to Figure 10 As shown, the air intake ports 102 of both the first intake chamber a and the second intake chamber are connected to the throttle valve 9. For example, the air intake ports 102 of both chambers are connected to the throttle valve 9. The compression ports 104 of both the first compression chamber b and the second compression chamber are connected to the combustion port 105. For example, the compression ports 104 of both chambers are connected to the combustion port 105.

[0100] The fourth protrusion 403, together with the power wheel 2, separates the outer space of the auxiliary component 4 into a second combustion chamber and a second exhaust chamber. The second combustion chamber communicates with the first combustion chamber c, and the second exhaust chamber communicates with the first exhaust chamber d. The outer periphery of the power wheel 2 is provided with a fourth recess 203 to avoid the fourth protrusion 403.

[0101] It is understandable that the power wheel 2 and the auxiliary component 4 can be arranged symmetrically, that is, they are the same size and shape, or they can be arranged asymmetrically, that is, the power wheel 2 and the auxiliary component 4 are similar in shape but different in size.

[0102] In this embodiment, during operation, the second air intake member and the third protrusion 402 work together to increase the volume of the second air intake chamber, drawing in gas through the air intake port 102. Simultaneously, the first air intake chamber a also draws in air through the air intake port 102. That is, the volumes of the first air intake chamber a and the second air intake chamber change synchronously, as do the volumes of the first compression chamber b and the second compression chamber.

[0103] As the auxiliary component 4 continues to rotate, the volume of the second compression chamber decreases, compressing the gas within. The first compression chamber b also undergoes a corresponding compression operation, and the compressed gas enters the combustion port 105 through the connected compression port 104.

[0104] The compressed gas enters the first combustion chamber c and the second combustion chamber, where it is ignited and generates energy to drive the power wheel 2 and auxiliary component 4 to continue rotating. Since the second combustion chamber is connected to the first combustion chamber c, the uniformity and efficiency of the combustion process are ensured. The second exhaust chamber is connected to the first exhaust chamber d, ensuring that exhaust gases are discharged uniformly and improving exhaust efficiency. In other words, the volumes of the first combustion chamber c and the second combustion chamber change synchronously, as do the volumes of the first exhaust chamber d and the second exhaust chamber.

[0105] With this configuration, the auxiliary component 4, through the third protrusion 402, the fourth protrusion 403, and the second air intake component, forms a second air intake chamber and a second compression chamber, which together with the first air intake compression system form a dual-path parallel air intake and compression circuit, thereby doubling the air intake volume and compressed air output volume per unit time compared to a single system.

[0106] These compressed gases are then combined and enter the interconnected first and second combustion chambers, forming a dual-chamber synchronous power output mode, which can significantly increase the power output. For example, under the premise of the same power target, the size of the engine can be significantly reduced.

[0107] In addition, the expansion force generated by combustion acts on the power wheel 2 and the auxiliary component 4 respectively. The two are subjected to opposite forces in space, which can form a torque balance system, thereby reducing the vibration caused by unilateral impact and significantly improving NVH performance.

[0108] refer to Figures 17-19 As shown, in some embodiments provided by the present invention, the number of first air intake components 3 is at least two, and the at least two first air intake components 3 are distributed along the circumference of the power wheel 2. The number of first protrusions 201 and first air intake components 3 is the same, and the two can divide the inner space of the power wheel 2 into at least two first air intake chambers a and at least two first compression chambers b.

[0109] Each of the first air intake chambers a is provided with an air inlet 102, and each of the first compression chambers b is provided with a compression outlet 104. For example, the volume of each of the first air intake chambers a changes synchronously, and the volume of each of the first compression chambers b changes synchronously.

[0110] In this embodiment, multiple first intake components 3 and first protrusions 201 are distributed circumferentially along the power wheel 2, making the force on the inner side of the power wheel 2 circumferentially uniform, thereby reducing radial off-center load when the power wheel 2 rotates. In addition, if a single intake component or first protrusion 201 experiences a minor malfunction, the remaining chambers can continue to operate, improving the stability of the engine.

[0111] refer to Figures 17-19As shown, in some embodiments provided by the present invention, the number of auxiliary components 4 is at least two, and the at least two auxiliary components 4 are distributed circumferentially along the power wheel 2. The number of second protrusions 202 and auxiliary components 4 is the same, and the two can divide the outer space of the power wheel 2 into at least two first combustion chambers c and at least two first exhaust chambers d.

[0112] Each of the first combustion chambers c is provided with a combustion port 105, and each of the first exhaust chambers d is provided with an exhaust port 103. For example, the volume of each first combustion chamber c changes synchronously, and the volume of each first exhaust chamber d changes synchronously.

[0113] In this embodiment, multiple auxiliary components 4 and the second protrusion 202 are distributed circumferentially along the power wheel 2, so that the combustion pressure on the outer side of the power wheel 2 is uniformly transmitted circumferentially. That is, the explosion pressure of each combustion chamber can form a circumferentially balanced driving force, reducing radial off-center load when a single chamber is working. In addition, if a single auxiliary component 4 or combustion chamber fails, the remaining units can continue to operate, improving the reliability of the engine.

[0114] In addition, the ignition timing of each combustion chamber's combustion port 105 can be independently controlled, and different loads can be adapted through group ignition.

[0115] It is understood that the two embodiments described above can be combined; specifically, refer to... Figures 17-19 As shown, there are at least two first air intake components 3, which are distributed circumferentially along the power wheel 2. The number of first protrusions 201 and first air intake components 3 is the same, and the two can divide the inner space of the power wheel 2 into at least two first air intake chambers a and at least two first compression chambers b. Each first air intake chamber a is provided with an air inlet 102, and each first compression chamber b is provided with a compression outlet 104.

[0116] Furthermore, the number of auxiliary components 4 is at least two, and the at least two auxiliary components 4 are distributed along the circumference of the power wheel 2. The number of second protrusions 202 is the same as that of auxiliary components 4, and the two can divide the outer space of the power wheel 2 into at least two first combustion chambers c and at least two first exhaust chambers d. Each first combustion chamber c is provided with a combustion port 105, and each first exhaust chamber d is provided with an exhaust port 103.

[0117] Correspondingly, each first combustion chamber c corresponds to a first compression chamber b inside the power wheel 2. For example, the number of first combustion chambers c and first compression chambers b are the same and they correspond one-to-one. Optionally, the first combustion chamber c is connected to the nearest first compression chamber b. Alternatively, each compression port 104 is connected, each combustion port 105 is connected, and then the compression port 104 and the combustion port 105 are connected.

[0118] In this embodiment, multiple first intake components 3 cooperate with multiple auxiliary components 4 to enable multiple intake, compression, combustion and exhaust processes to work in parallel, thereby significantly improving the overall performance of the engine.

[0119] For example, because multiple chambers operate simultaneously, more work cycles are completed per unit time, increasing power density. Furthermore, the even distribution of multiple combustion and compression chambers averages out torque fluctuations, resulting in smoother power output, reduced vibration, and avoidance of single-point impacts, thus improving NVH performance. Additionally, multi-point combustion accelerates flame propagation speed, reduces incomplete combustion, and increases combustion efficiency, thereby improving thermal efficiency. Finally, multiple exhaust ports (103) distribute the exhaust load, reduce back pressure, improve scavenging efficiency, and ensure smoother exhaust flow.

[0120] Optionally, each auxiliary component 4 has a corresponding second air intake component on its inner side. The arrangement of the second air intake component has been discussed above and will not be repeated here. In this embodiment, the number of intake and compression units can be further increased to improve the engine's intake efficiency and power density.

[0121] Furthermore, the compression port 104 corresponding to the second compression chamber formed by the second air intake component can be connected to the nearest combustion port 105. This configuration reduces flow losses through short-path air supply, improves response speed and combustion timeliness, and makes the entire system operate more efficiently and smoothly.

[0122] Optionally, refer to Figure 17 As shown, each air intake 102 is equipped with a corresponding throttle valve 9, or refer to Figure 19 As shown, each air intake 102 is connected and is connected to the throttle valve 9.

[0123] Optionally, refer to Figure 17 As shown, the diameter of auxiliary component 4 is equal to the diameter of the power wheel 2, or as referenced Figure 19 As shown, the diameter of auxiliary component 4 is smaller than the diameter of power wheel 2.

[0124] In some embodiments provided by the present invention, the number of power wheels 2 is at least two, and the power wheels 2 are arranged sequentially along the axial direction, for example, the power wheels 2 share the same pivot 7. Accordingly, each power wheel 2 is provided with a corresponding first air intake 3 and an auxiliary component 4, wherein the auxiliary component 4 may share a pivot 7. Optionally, the housing 1 is divided into multiple independent chambers along the axial direction of the power wheels 2, and the power wheels 2 are respectively arranged in the corresponding chambers.

[0125] In this embodiment, multiple power wheels 2 can operate simultaneously, equivalent to multiple cylinders connected in parallel, thereby increasing the total power. Each chamber is independently sealed to avoid mutual interference, which can improve operational stability and reliability. In addition, the shared pivot 7 design simplifies the structure, reduces weight and assembly complexity, and is conducive to achieving high power density.

[0126] Furthermore, by ensuring that the two pivots 7 are connected in a transmission or that one set of working wheels 2 is connected to the auxiliary component 4, all components can be driven to operate synchronously, thereby simplifying the mechanical structure and reducing assembly complexity and manufacturing costs.

[0127] In some embodiments provided by the present invention, the power wheel 2 closes the combustion port 105, and when the first protrusion 201 approaches, reaches or crosses the compression port 104, the power wheel 2 opens the combustion port 105.

[0128] For example, when the first protrusion 201 approaches the compression port 104, it can be understood as the moment when the first protrusion 201 is about to arrive but has not yet arrived; when the first protrusion 201 reaches the compression port 104, it can be understood as the moment when the first protrusion 201 and the compression port 104 at least partially overlap; when the first protrusion 201 crosses the compression port 104, it can be understood as the moment when the first protrusion 201 has separated from the compression port 104.

[0129] It can be understood that when the first protrusion 201 approaches, reaches or crosses the compression port 104, the corresponding compression stroke ends. In specific applications, the appropriate time can be selected as the time when the compression stroke ends according to the actual compression requirements, and there is no limitation on this.

[0130] In some embodiments provided by the present invention, the end face of the power wheel 2 is provided with a notch, and the combustion port 105 is located on the rotation path of the notch. When the notch rotates to be opposite to the combustion port 105, the combustion port 105 is opened.

[0131] In this embodiment, when the notch rotates with the power wheel 2 to be opposite the combustion port 105, the combustion port 105 is opened, and compressed gas enters the combustion chamber. When the notch rotates away, the combustion port 105 is closed by the end face of the power wheel 2, achieving a seal.

[0132] This structure utilizes the rotational motion of the power wheel 2 to open and close the combustion port 105, which not only simplifies the structure and reduces mechanical complexity but also improves system reliability. Furthermore, by precisely designing the position and shape of the notch, the timing and duration of combustion can be accurately controlled, optimizing combustion efficiency and power output rhythm, thus achieving a highly efficient, compact, and adjustable rotary engine working cycle.

[0133] Furthermore, the fourth recess 203 on the outer periphery of the power wheel 2 constitutes the notch.

[0134] In this embodiment, the fourth recess 203 can both avoid the fourth protrusion 403 on the auxiliary member 4 during rotation and serve as an opening structure for the combustion port 105. When the fourth recess 203 rotates to be opposite the combustion port 105, the combustion port 105 opens, and it automatically closes after rotating away.

[0135] With this design, the fourth recess 203 simultaneously serves the dual functions of "avoiding the protrusion" and "controlling the opening and closing of the combustion port 105". This not only reduces the number of parts and the complexity of processing, but also improves space utilization and the coordination of movement sequence, making the intake, compression, combustion and exhaust processes more compact and efficient, and further enhancing the overall integrity and reliability of the engine.

[0136] Of course, it is understood that the method is not limited to closing the combustion port 105 by the power wheel 2. For example, in some embodiments not shown, a control valve can be provided between the compression port 104 and the combustion port 105 to control the opening and closing of the combustion port 105. The control valve includes, but is not limited to, a solenoid valve.

[0137] In some embodiments provided by the present invention, the rotary engine further includes an igniter 5 disposed in the first combustion chamber c. The igniter 5 includes, but is not limited to, a spark plug.

[0138] In this embodiment, the igniter 5 is disposed in the first combustion chamber c and is used to ignite the high-pressure combustible mixture at the end of the compression stroke to trigger combustion and work.

[0139] This invention also provides a vehicle, including but not limited to vehicles, aircraft, and ships.

[0140] Specifically, the vehicle includes the rotary engine described above.

[0141] It should be noted that the vehicle incorporates a rotary engine, and therefore also incorporates all the advantages of a rotary engine mentioned above.

[0142] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
