Among them, a piston engine is an engine that uses one or more pistons to convert pressure into rotational kinetic energy, and converts linear motion into rotational motion through a crank-connecting rod mechanism, and has a complex structure and low energy conversion efficiency.

[0012] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0013] 1. The combustion chamber of the core engine is formed by a stator, a rotor, a rotor valve plate and a stator valve plate to form a closed combustion chamber, which can directly convert the transmitted energy into rotational motion. By applying the principles of mechanics, it can perform work within the range of 0 to 330 degrees.

[0015] 3. When the rotor and the rotor valve plate rotate relative to the stator, the area of ​​the exhaust chamber cavity decreases as the area of ​​the combustion chamber cavity increases, so that the exhaust gas in the exhaust chamber is discharged through the exhaust port. On the one hand, it can ensure the pressure difference between the combustion chamber and the exhaust chamber, avoid explosions caused by poor exhaust, and have high safety performance. On the other hand, when the air is introduced under the action of the fan, part of it will rotate into the first heat dissipation channel to achieve cooling of the rotor.

[0016] 4. The compressed air that is swirled in fills the inner cavity of the stator, which, on the one hand, heats and cools the stator at the same time. On the other hand, the stator is provided with a second heat dissipation channel, which can take away the heat inside the stator and achieve internal cooling. Compared with traditional engines, no additional cooling system is required to cool the inside of the engine.

[0017] 5. By adopting constant pressure combustion expansion and the cam structure on the stator and rotor, the high-speed movement impact can be effectively reduced and the output stability can be increased. It can also adapt to multiple fuels and use clean fuels to reduce emission pollution. In addition, the functions of the stator and rotor can be interchanged according to actual conditions.

DETAILED DESCRIPTION

[0027] like Figure 1-Figure 6As shown, the present invention provides a core engine, including a compressor, a combustion chamber 32, an ignition assembly and a fuel delivery assembly arranged in a shell, the compressor, the ignition assembly and the fuel delivery assembly are respectively connected to the combustion chamber 32, a central axis 34 runs through the center of the shell, an upper mounting plate 1 mounted on the top of the shell is sleeved on the upper end of the central axis 34, a plurality of first air inlets 101 connected to one end of the compressor are uniformly arranged on the upper mounting plate 1 in the circumferential direction, a lower mounting plate 17 mounted on the bottom of the shell is sleeved on the lower end of the central axis 34, a stator and a rotor are connected to the outer periphery of the central axis 34 in sequence, a stator valve plate 30 and a rotor valve plate 31 are arranged between the stator and the rotor, one end of the stator valve plate 30 is hinged to the stator, and the stator The other end of the valve plate 30 moves along the inner circumference of the rotor, one end of the rotor valve plate 31 is hinged to the rotor, and the other end of the rotor valve plate 31 moves along the outer circumference of the stator. The stator, the rotor, the stator valve plate 30 and the rotor valve plate 31 form independent combustion chambers 32 and exhaust chambers. The stator is provided with a second air inlet 36 and a third air inlet 37. The second air inlet 36 is connected to the other end of the air compressor, and the third air inlet 37 is connected to the combustion chamber 32. A valve assembly 29 is provided at the third air inlet 37. The rotor is provided with an exhaust port 33 connected to the exhaust chamber. The stator is also provided with a spring push rod 28, one end of which is hinged to the stator, and the other end of the spring push rod 28 corresponds to one end of the stator valve plate 30.

[0028] In this embodiment, Figure 7(a) to Figure 7(d) As shown, air enters the air compressor through the first air inlet 101 under the action of the air compressor, and forms compressed air in the air compressor, and then enters the stator cavity continuously through the second air inlet 36. The valve assembly 29 is opened under the action of the timing mechanism 15, and the compressed air is filled into the combustion chamber 32 along the third air inlet 37. At the same time, the fuel delivery assembly delivers fuel to the combustion chamber 32, and the fuel and compressed air form a combustible mixture, which is ignited by the ignition assembly. The rotor and the rotor valve plate 31 rotate relative to the stator under the impetus of the high-temperature combustion gas, thereby increasing the cavity area of ​​the combustion chamber 32 and reducing the cavity area of ​​the exhaust chamber. When the rotor and the rotor valve plate 31 rotate to a certain angle relative to the stator (the angle in this embodiment is 330 degrees), the stator valve plate 30 is opened under the action of the spring push rod 28, so that the combustion chamber 32 is connected with the exhaust chamber, and the burned gas in the combustion chamber 32 is discharged through the exhaust port 33, thereby completing one work, and the rotor and the rotor valve plate 31 continue to rotate and reset to enter the next cycle.

[0029] The valve assembly 29 includes a valve, a guide tube, a valve spring, a spring seat, a locking plate, and a snap ring. Its function is to control the opening and closing of the third air inlet 37. When the rotor rotates to the corresponding position, the timing mechanism 15 controls the valve assembly 29 to open. The spring push rod 28, the ignition assembly, and the fuel delivery assembly are respectively connected to the timing mechanism 15, and the timing mechanism 15 controls the actions of the spring push rod 28, the ignition assembly, and the fuel delivery assembly. In this embodiment, the spring push rod 28 adopts a pneumatic spring push rod.

[0030] In this embodiment, the connection modes of the spring push rod 28, the ignition assembly and the fuel delivery assembly to the timing mechanism 15 are conventionally used by those skilled in the art, and their functions are also conventionally used by those skilled in the art. This application does not improve the above connection modes and functions, so there is no need to elaborate in the application documents.

[0031] The number of combustion chambers 32 is at least one. In this embodiment, there are two combustion chambers 32, which are axially and centrally symmetrically arranged. The specific installation structure is as follows: Figure 1 As shown, the stator and the rotor are respectively arranged in two axial directions along the central axis 34, wherein each stator includes a stator body, a stator support 11 and a stator bracket 14 respectively arranged at the upper and lower ends of the stator body, and the rotor includes a rotor body, a rotor bracket 15 and a rotor end cover 10 respectively arranged at the upper and lower ends of the rotor body.

[0032] The combustion chamber 32 of the core engine of this embodiment is formed by a stator, a rotor, a rotor valve plate 31 and a stator valve plate 30 to form a closed combustion chamber 32, which can directly convert the transmitted energy into rotational motion. By applying the principles of mechanics, it can perform work within a range of 0 to 330 degrees. Compared with traditional piston 24 engines and turbojet engines, it omits the linear motion process, simplifies the structure, reduces energy loss, and improves energy conversion efficiency.

[0033] In addition, when the rotor and the rotor valve plate 31 rotate relative to the stator, as the cavity area of ​​the combustion chamber 32 increases, the cavity area of ​​the exhaust chamber decreases, so that the exhaust gas in the exhaust chamber is discharged through the exhaust port 33. On the one hand, the pressure difference between the combustion chamber 32 and the exhaust chamber can be ensured to avoid explosions caused by poor exhaust, and the safety performance is high. On the other hand, when the air is introduced under the action of the fan 4, a part of it will rotate into the first heat dissipation channel to achieve cooling of the rotor.

[0034] Recombination Figure 5 , Figure 6 , Figure 7(a) to Figure 7(d)As shown, when the core engine of this embodiment is burning on one side, the rotor and the rotor valve plate 31 rotate relative to the stator at the same time, which can achieve constant pressure combustion. By adopting constant pressure combustion expansion and the cam structure on the stator and rotor, the high-speed motion impact can be effectively reduced and the output stability can be increased. It can also adapt to multiple fuels, and the use of clean fuel can reduce emission pollution. In addition, the functions of the stator and the rotor can be interchanged according to actual conditions, that is, in this embodiment, the rotor and the rotor valve plate 31 rotate relative to the stator, and the stator and the stator valve plate 30 can also rotate relative to the rotor.

[0035] Further, the air compressor includes a motor rotor bracket 3 sleeved on the central shaft 34 and hinged thereto, wherein the motor rotor bracket 3 is connected to the central shaft 34 through the upper bearing 2, the motor rotor bracket 3 is arranged at the lower part of the upper mounting plate 1, the outer periphery of the motor rotor bracket 3 is connected to the fan 4 and the support frame 5, the lower part of the support frame 5 is connected to the compression cam 6, the lower surface of the compression cam 6 is in contact with the roller 7, the lower surface of the compression cam 6 is an uneven and smoothly connected curved surface structure, the roller 7 is fixed to the piston 24, the piston 24 is arranged in the cylinder body 8, the outer periphery of the cylinder body 8 is sequentially connected to the motor stator 9 and the motor rotor 25, the motor rotor 25 is connected to the support frame 5, the cylinder body 8 is circumferentially provided with a reset assembly connected to the piston 24, and the lower part of the piston 24 is circumferentially provided with a plurality of intake valve plates 23 hinged thereto. Among them, the intake valve plate 23 is connected to the piston 24 through the rotating shaft 22.

[0036] In this structure, the air compressor is used to compress the air and deliver it to the combustion chamber 32. Specifically, the motor rotor 25 drives the support frame 5 and the fan 4 to rotate in turn. Under the action of the fan 4, the air rotates to the inner cavity of the cylinder body 8 through the first air inlet 101. The compression cam 6 rotates under the drive of the support frame 5 and contacts with the roller 7. Since the lower surface of the compression cam 6 is an uneven and smoothly connected curved surface structure, the roller 7 drives the piston 24 to move up and down relative to the cylinder body 8 under the action of the compression cam 6 and the reset assembly. When the piston 24 moves upward, the intake valve plate 23 opens, thereby realizing the introduction of air. When the piston 24 moves downward, the intake valve plate 23 closes, and the air pressure in the lower part of the inner cavity of the cylinder body 8 gradually increases, forming compressed air.

[0037] Furthermore, an air-isolating assembly is provided at the lower portion of the cylinder body 8, and the air-isolating assembly includes a support rod 20, a one-way valve plate 19 and a spring 21. The support rod 20 is sleeved on the outer periphery of the central axis 34, and the one-way valve plate 19 slides horizontally along the support rod 20 and is connected to the outer periphery of the support rod 20. The one-way valve plate 19 corresponds to the inner periphery position of the lower portion of the cylinder body 8, and the spring 21 is provided on the support rod 20 and respectively abuts against the central axis 34 and the support rod 20.

[0038] In this structure, the air barrier assembly is provided to control the opening and closing of the bottom of the cylinder body 8. When the piston 24 descends to the lower part of the cylinder body 8, the compressed gas pushes the one-way valve plate 19 to slide horizontally along the support rod 20, so that the opening at the bottom of the cylinder body 8 opens and is transported to the stator inner cavity through the second air inlet 36.

[0039] Furthermore, the reset assembly includes a spring fixing plate 27 and a tension spring 26. The spring fixing plate 27 is sleeved on the outer periphery of the central shaft 34 and fixed to the motor rotor bracket 3. The two ends of the tension spring 26 are respectively in contact with the spring fixing plate 27 and the piston 24. In this structure, the reset assembly is arranged to ensure that the roller 7 is always in contact with the lower surface of the compression cam 6, so as to ensure that the piston 24 can move up and down relative to the cylinder body 8, thereby realizing the introduction of air.

[0040] The air compressor of this embodiment is provided with an intake valve plate 23 and an air separator assembly hinged to the piston 24, so that the input of the combustion-supporting compressed gas with a high pressure ratio (ηk>20) can be realized. The combustion-supporting compressed gas with a high pressure ratio and the fuel enter the combustion chamber 32 separately, and no explosion will occur. Moreover, the oil-gas ratio can be adjusted arbitrarily to improve the energy conversion efficiency. In addition, the air compressor is arranged in the axial direction of the combustion chamber 32, and the introduced airflow flows along the axial direction, which can increase the axial thrust of the core engine.

[0041] Furthermore, a first heat dissipation channel is provided between the outer periphery of the fan 4 and the housing. When air is introduced under the action of the fan 4, a part of the air will rotate into the first heat dissipation channel to achieve cooling of the rotor.

[0042] The stator is provided with a second heat dissipation channel, and the compressed air that is spun in fills the inner cavity of the stator, which, on the one hand, heats the stator while cooling it. On the other hand, the stator is provided with a second heat dissipation channel, which can take away the heat inside the stator to achieve internal cooling. Compared with traditional engines, no additional cooling system is required to cool the inside of the engine.

[0043] Furthermore, one end of the stator valve plate 30 is provided with a bump corresponding to the other end of the spring push rod 28. The timing mechanism 15 controls the spring push rod 28, and the popped-out push rod pushes the bump, thereby driving the stator valve plate 30 to rotate relative to the stator, thereby achieving communication between the gas chamber and the exhaust chamber.

[0044] Furthermore, the fuel delivery assembly includes a fuel pump 16 and a fuel injector 12 . The fuel injector 12 is connected to the fuel pump 16 through a fuel pipeline 38 . The fuel pump 16 is connected to the fuel tank. The fuel pump 16 is disposed on a lower mounting plate 17 . The fuel injector 12 extends into the combustion chamber 32 .

[0045] Furthermore, the ignition assembly includes an ignition coil 35 and a spark plug 13. The ignition coil 35 is disposed in the air compressor, the ignition coil 35 is connected to the spark plug 13, the ignition coil 35 is electrically connected to the output end of the switch device, the input end of the switch device is electrically connected to the timing mechanism 15, and the spark plug 13 extends into the combustion chamber 32. In this structure, since the temperature at the air compressor is relatively low, the ignition coil 35 is disposed at the position of the air compressor, which can extend the service life of the ignition coil 35.
