Description

Technical Field

[0001] The invention belongs to the technical field of engines, and in particular relates to a pressure storage engine and a working method. Background Art

[0002] Existing engine technology relies on the cylinder to inhale air, mix it with fuel, burn it, expand it, and do work to generate power, which consumes non-renewable resources and causes environmental pollution due to exhaust emissions. However, the normal air pressure on the earth is relatively low, which makes the thermal efficiency of the combustion chamber low. To improve the combustion efficiency, you can choose to consume energy to compress the intake air to a certain proportion. Therefore, similar devices such as turbochargers have appeared to increase the intake volume to increase the cylinder pressure and thus improve the thermal efficiency. However, the combustion heat release efficiency of the fuel is still limited, exhaust emissions are still polluting, and the consumption of non-renewable resources is also unavoidable. After using the worm gear supercharging method to increase the compression ratio to increase the combustion output power, there are few more effective ways to increase power.

[0003] In response to the demand for energy conservation and emission reduction, electric engines came into being. They have advantages in the consumption of non-renewable resources and exhaust emissions, and are also widely used and promoted.

DETAILED DESCRIPTION

[0034] The specific implementation modes of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] See also Figure 1-4The storage engine of a specific embodiment comprises a main housing 1, wherein a group of cylinders and a rotatable crankshaft 2 are arranged in the main housing 1; the group of cylinders comprises a first cylinder 11 and a second cylinder 12; an intake valve 111 is provided on the main housing 1 and the intake valve 111 is communicated with the first cylinder 11; an exhaust valve 121 is provided on the main housing 1 and the exhaust valve 121 is communicated with the second cylinder 12; a channel valve 13 is also provided on the main housing 1 and the channel valve 13 communicates the first cylinder 11 with the second cylinder 12; the crankshaft 2 is connected to a first piston 21 and a first piston 22 which can slide in the first cylinder 11 and a first piston 23 which can slide in the first cylinder 11 and a first piston 24 which can slide in the first cylinder 11 and a first piston 25 which can slide in the first cylinder 11 and a first piston 26 which can slide in the first cylinder 11 and a first piston 27 which can slide in the first cylinder 11 and a first piston 28 which can slide in the first cylinder 11 and a first piston 29 ... A second piston 22 is slidable in the second cylinder 12; electrode columns that can cooperate with discharge are respectively provided on the inner wall of the second cylinder 12 and the end face of the second piston 22 so that when the second piston 22 moves to the stroke limit position, the two electrode columns are brought close to each other to generate a high-temperature arc between the end face of the second piston 22 and the inner wall of the second cylinder 12; the air port of the channel valve 13 on the second cylinder 12, the exhaust valve 121 and the electrode column on the inner wall of the second cylinder 12 are all located at the same end of the second cylinder 12, and the air port of the channel valve 13 on the first cylinder 11 and the intake valve 111 are located at the same end of the first cylinder 11;

[0036] The intake valve 111 and the exhaust valve 121 are respectively connected to the gas storage tank 3 containing compressed gas medium. A cooling device is also provided between the exhaust valve 121 and the gas storage tank 3 for cooling the refluxed compressed gas medium. The opening and closing of each valve is controlled by a valve control unit.

[0037] The pressure storage engine of the embodiment realizes work and external output torque through the thermal expansion of compressed gas, which can reduce the consumption of non-renewable resources; during use, it only needs to replenish the compressed gas medium and the electric energy required for discharge and cooling devices, which is easy to use and low in cost; through the reasonable matching of gas pressure and discharge arc temperature, its working efficiency can be better than many existing fuel-fired internal combustion engines, and it has strong applicability.

[0038] When in use, it includes alternating cycles of power stroke and exhaust stroke to achieve continuous output of torque.

[0039] See also Figure 1 , Figure 2, wherein the power stroke includes: the second piston 22 moves to the stroke limit position, under the control of the valve control unit, the intake valve 111 is opened, the channel valve 13 is closed, and the exhaust valve 121 is closed, and the end face of the second piston 22, the closed channel valve 13, the exhaust valve 121 and the corresponding inner wall of the second cylinder 12 together constitute the closed cylinder space; the two electrode columns are close to each other and discharge occurs, and the high-temperature arc of the discharge causes the compressed gas medium in the closed cylinder space to expand and push the second piston 22 to do work, and the second piston 22 pushes the crankshaft 2 to rotate, and the crankshaft 2 drives the first piston 21 away from the intake valve 111 so that the compressed gas medium enters the first cylinder 11 from the gas storage tank 3; it can be seen that the power stroke is also the intake stroke of the first piston 21.

[0040] The exhaust stroke includes: the second piston 22 moves to the extreme position at the other end of its stroke, and under the control of the valve control unit, the intake valve 111 is closed, the channel valve 13 is opened, and the exhaust valve 121 is opened; the crankshaft 2 continues to rotate, driving the first piston 21 to slide toward the intake valve 111 and push the compressed gas medium in the first cylinder 11 into the second cylinder 12 through the channel valve 13. At the same time, the crankshaft 2 also drives the second piston 22 to slide toward the exhaust valve 121 and pushes the high-temperature compressed gas medium after work in the second cylinder 12 out through the exhaust valve 121. When the second cylinder 12 is exhausted, the first piston 21 is The compressed gas medium in the cylinder 11 enters the second cylinder 12 through the channel valve 13, which can ensure that the high-temperature medium in the second cylinder 12 is effectively discharged; wherein, the continued rotation of the crankshaft 2 in the exhaust stroke relies on inertial force. The inertial force must be greater than the pressure exerted on the first piston 21 and the second piston 22 in the exhaust stroke to ensure the circulation operation. The inertial force can be provided by the mass of the crankshaft 2, or by the external flywheel 23. Both are conventional technologies. The flywheel 23 is also externally connected as shown in the figure of this embodiment. In addition, the power of the exhaust stroke can be provided to each other by alternating the work of multiple cylinders.

[0041] Then, the high-temperature compressed gas medium is cooled by the cooling device and flows back into the gas storage tank 3. The arrows in the figure indicate the flow direction of the compressed gas medium.

[0042] During implementation, the pressure of the compressed gas medium is 1Mpa to 50Mpa; the temperature of the high-temperature arc is 2000 to 8000 Kelvin.

[0043] In addition, at the time of starting, it is only necessary to drive the flywheel 23 through the starter 24 to rotate the crankshaft 2 and drive the second piston 22 to move to the discharge position, and then start the above-mentioned power stroke, the engine works normally and continuously outputs torque, and the starter 24 is disengaged from the flywheel 23 through the clutch, which is similar to the prior art and will not be repeated here.

[0044] During implementation, based on the above principles, the valve control unit can be electronically controlled or mechanically controlled; the intake valve 111 and the exhaust valve 121 can be set at either end of the piston, and the angular relationship between the two cylinders in the circumferential direction can also be changed, as long as the specific design of the relative angles between the crankshaft 2 is achieved so that the movement of the piston combined therewith can meet the above-mentioned power stroke and exhaust stroke; the present invention is not limited thereto.

[0045] The first cylinder 11 and the second cylinder 12 are in-line, that is, they are arranged side by side and parallel to each other, and the intake valve 111 and the exhaust valve 121 are located at the same end and at the end of the corresponding cylinder away from the crankshaft 2. When the crankshaft 2 rotates, the two pistons move in the same direction in the corresponding cylinder.

[0046] The crankshaft 2 is usually connected to the connecting rod through the connecting rod journals on each crank, and then connected to the piston. The same-end structural form can simplify the design difficulty and the manufacturing difficulty of the main housing 1 and the crankshaft 2. The corresponding two cranks have the same angle in the circumferential direction.

[0047] The valve control unit includes a camshaft 16 and a valve valve 17 corresponding to each valve to control the opening and closing of the corresponding valve by rotating the camshaft 16. The camshaft 16 is rotatably connected to the main housing 1 and linked to the crankshaft 2. When the two pistons are close to the crankshaft 2, the intake valve 111 is opened, and the channel valve 13 and the exhaust valve 121 are closed. When the two pistons are away from the crankshaft 2, the intake valve 111 is closed, and the channel valve 13 and the exhaust valve 121 are opened.

[0048] In this way, the valve control unit of this embodiment still chooses the camshaft 16 of conventional mechanical structure to control the opening and closing of the valve, which is stable and reliable; functional protrusions should be provided at intervals on the camshaft 16 to act on the valve 17 as the camshaft 16 rotates. The valve valve 17 is a combination of a valve cover and a rod. The rod passes through the corresponding through hole on the main housing 1 and is connected to the valve cover at the valve port of the cylinder end. The rod is covered with a spiral compression spring for return stroke. These are all conventional means and will not be repeated.

[0049] The valve 17 of the channel valve 13 controls the valve port position of the channel valve 13 on the second cylinder 12 .

[0050] In this way, the channel valve 13 originally has an air port on both the first cylinder 11 and the second cylinder 12, and it is only necessary to set the valve valve 17 at any one of the air ports. In this embodiment, the valve valve 17 is set at the air port on the side of the second cylinder 12. The force of the valve valve 17 is more matched with the actual operating condition of the second cylinder 12, and the air intake and sealing effects are better, and the service life is longer.

[0051] The two electrode columns are respectively connected to an arc generator 5 to obtain a high-temperature arc during discharge, thereby increasing power;

[0052] In this way, the arc generator 5 of the mature product is used to provide a high temperature arc, which is stable, reliable and has adjustable power. The traditional spark plug also generates heat through arc, but its calorific value is small and can only be used for ignition, which is not suitable for the heating use of this structure.

[0053] The arc generator 5 is a DC arc generator 5, whose anode is electrically connected to the electrode column on the second cylinder 12 through an electric wire so that the electrode column on the second cylinder 12 is formed into an anode column 14; its cathode is overlapped with the main shell 1 to be electrically connected to the electrode column on the second piston 22 so that the electrode column is formed into a cathode column 221; the anode column 14 and the main shell 1 are insulated. During specific operation, a high-temperature resistant ceramic sleeve can be provided between the anode column 14 and the main shell 1, and the electric wire has its own insulating sheath; the exposed length of the anode column 14 can be adjusted and can be effectively fixed after adjustment; the appropriate discharge distance between the anode column 14 and the cathode column 221 can be determined according to the power of the arc generator 5.

[0054] In this way, a DC arc generator 5 is further selected, which is simple to connect and use, has better applicability, and the specific connection form of the positive and negative levels allows the main shell 1 to be connected to the cathode, which can effectively ensure the safety of electricity use; during implementation, the anode column 14 and the cathode column 221 can be multiple pairs of relatively matched settings, which can be adjusted according to the required engine power. In this embodiment, two pairs are correspondingly arranged on the second piston 22 and the second cylinder 12, and the discharge security during the power stroke is also better.

[0055] Among them, the intake valve 111 is connected to the air storage tank 3 through the intake pipe 31, and the exhaust valve 121 is connected to the air storage tank 3 through the exhaust pipe 32. The intake pipe 31 is provided with a valve body 311 for controlling the flow and is controlled by an air flow controller 312 connected thereto. The intake pipe 31 is also connected to a pressure gauge 313.

[0056] In this way, it can play the role of a throttle, and the power and speed of the machine can be controlled by the intake air flow controller 312. When the intake is large, the power is large and the speed is high, and when the intake is small, the power is small and the speed is low; it is easy to adjust.

[0057] The gas medium is air, nitrogen or helium; the cooling device includes a heat sink 6 and a water tank 4, and the heat sink 6 is provided on the outer wall of at least a portion of the exhaust pipe 32 and the intake pipe 31;

[0058] In this way, the heat can be effectively dissipated to reduce the temperature of the refluxed high-temperature compressed gas medium. The better the cooling effect, the more favorable the power effect. In this embodiment, heat sinks 6 are provided on both the exhaust pipe 32 and the intake pipe. Compressed air can be used, but compressed air contains oxygen, which will affect the service life of the cathode and anode. It is preferred to use a gas without oxygen, such as nitrogen, which can extend the service life of the cathode and anode.

[0059] The exhaust passage also passes through the water tank 4 to better cool the refluxed compressed gas medium; the water tank 4 is connected to the water-cooling circulation passage 15 in the main shell 1 through a circulating water channel 41; a temperature-controlled fan 42 is connected to the water tank 4 to cool the water tank 4, a temperature sensor 43 is built into the water tank 4, and the temperature sensor 43 is externally connected to a temperature meter 44 to display the temperature inside the water tank 4, and the temperature sensor 43 is also electrically connected to the temperature-controlled fan 42 so that the electrical rotation speed of the temperature-controlled fan 42 can match the temperature inside the water tank 4.

[0060] In this way, the high-temperature compressed gas medium that flows back is further cooled by the conventional water tank 4. Although the circulating water medium in the water tank 4 also brings back the temperature of the main shell 1, it can still play a role in heat exchange and cooling it down compared with the high-temperature compressed gas medium after work. When it is implemented, the exhaust channel can be S-shaped in the water tank 4 and finally pass through, and the other space in the water tank 4 is circulating water. Alternatively, the circulating water channel 41 can be S-shaped in the water tank 4, and the high-temperature compressed gas medium is sent into the water tank 4 and then discharged. The exhaust channel and the aluminum sheets of the stacked structure of the conventional water tank 4 can also be staggered, as long as the heat exchange effect can be achieved. The water-cooled circulation channel 15 in the main shell 1 can adopt existing means, which will not be repeated.

[0061] Among them, the gas storage tank 3 is connected to an air supply pipeline, on which a one-way valve 33 is provided. The gas storage tank 3 is also provided with a pressure relief valve 34 and a safety valve 35. The safety valve 35 is provided with a safety protection cover 36 with a porous structure outside so that when the gas storage tank 3 is abnormally deformed, the safety valve 35 can be automatically pressed open and the air pressure can be released through several small holes of the safety protection cover 36 to avoid injury; the bottom of the gas storage tank 3 is also provided with an openable and closable sewage outlet 37.

[0062] Like this, be convenient for replenishing gas and maintaining pressure, certainly, gas storage tank 3 also can be replaced when necessary.

[0063] Among them, one end of the crankshaft 2 passes through the main housing 1 and is connected to the flywheel 23, and the flywheel 23 is connected to the starter 24 in a transmission manner; the corresponding end of the camshaft 16 also passes through the main housing 1 and is connected to the end of the crankshaft 2 passing through the main housing 1 through a synchronous belt 25 to achieve linkage;

[0064] In this way, this embodiment still selects the conventional flywheel 23 to provide inertial force. If necessary, a tensioning wheel 26 can be set on the synchronous belt 25 that links the camshaft 16 and the crankshaft 2 to ensure the use effect. The relevant structural form and starting are similar to the existing means and will not be repeated.

[0065] The end of the crankshaft 2 passing through the main housing 1 is also connected to the generator 7 to drive the generator 7 to generate electricity, and the generator 7 is connected to the battery 71 to power the electronic devices; the end of the crankshaft 2 passing through the main housing 1 is detected by the speed sensor 27 and the speed sensor 27 is connected to the tachometer 28 to display the speed.

[0066] In this way, power is maintained and the use time is extended. The storage battery 71 can at least supply power to the arc generator 5, the temperature control fan 42, the air flow controller 312, etc. in the engine structure.

[0067] There are two groups of cylinders in the main housing 1, both of which are in-line. The structure of the crankshaft 2 corresponds to it, and the two groups of cylinders work alternately.

[0068] In this way, the engine power can be improved, and the two groups of cylinders can provide each other with power for the exhaust stroke by working alternately, avoiding excessive requirements on the flywheel 23. From a structural point of view, the crankshafts corresponding to the two groups of cylinders are arranged at 180 degrees. Of course, in order to further improve the power, the number of cylinders can be increased in groups, as long as the circumferential angles of the crankshafts are designed to match the corresponding ones.

[0069] Among them, on the crankshaft 2, the diameter of the crankshaft connected to the first piston 21 is smaller than the diameter of the crankshaft connected to the second piston 22, specifically referring to the distance from the connecting journal to the axis.

[0070] In this way, energy consumption can be reduced without affecting power. Because too much compressed gas medium flowing in the pipeline will generate heat, increasing the energy consumed for cooling, so the stroke of the first piston 21 is made smaller than the stroke of the second piston 22 to ensure that the intake of the first cylinder 11 in the intake stroke can effectively push out the high-temperature gas medium of the second cylinder 12.

[0071] During implementation, the main housing 1 includes a cylinder block and a cylinder head. The cylinder head is preferably the portion above the camshaft 16 to facilitate the manufacture of the cylinder block and the cylinder head. The cylinder block can be an integral structure or an assembled structure. Existing means are not described in detail.

[0072] During implementation, the existing oil pump 8 and oil filter 81 may also be included to lubricate the structure; in the figure, the oil pump 8, oil filter 81, generator 7 and main housing 1 overlap in space and are not inside the main housing 1.

[0073] The present invention also provides an engine working method: comprising: in a closed cylinder space, a high-temperature arc generated by discharge causes the compressed gas medium to expand thermally to push the piston to work, and the working stroke of the piston pushes the crankshaft 2 to output torque.

[0074] Specifically, the method is performed based on the above-mentioned storage pressure engine, and includes alternating cycles of power stroke and exhaust stroke to achieve continuous output of torque;

[0075] The power stroke includes: the second piston 22 moves to the stroke limit position, under the control of the valve control unit, the intake valve 111 is opened, the channel valve 13 is closed, and the exhaust valve 121 is closed, and the end surface of the second piston 22, the closed channel valve 13, the exhaust valve 121 and the corresponding inner wall of the second cylinder 12 together constitute the closed cylinder space; the two electrode columns are close to each other to generate discharge, and the high-temperature arc of the discharge causes the compressed gas medium in the closed cylinder space to expand thermally and push the second piston 22 to work, and the second piston 22 pushes the crankshaft 2 to rotate, and the crankshaft 2 drives the first piston 21 away from the intake valve 111 so that the compressed gas medium enters the first cylinder 11 from the gas storage tank 3;

[0076] The exhaust stroke includes: the second piston 22 moves to the extreme position at the other end of its stroke, and under the control of the valve control unit, the intake valve 111 is closed, the channel valve 13 is opened, and the exhaust valve 121 is opened; the crankshaft 2 continues to rotate, driving the first piston 21 to slide toward the intake valve 111 and push the compressed gas medium in the first cylinder 11 into the second cylinder 12 through the channel valve 13, and at the same time, the crankshaft 2 also drives the second piston 22 to slide toward the exhaust valve 121 and push the high-temperature compressed gas medium after work in the second cylinder 12 out through the exhaust valve 121;

[0077] The high-temperature compressed gas medium is cooled by the cooling device and then flows back into the gas storage tank 3;

[0078] The second piston 22 moves to the upper stroke limit position and switches under the control of the valve control unit, the intake valve 111 opens, the channel valve 13 closes, the exhaust valve 121 closes, and enters the power stroke again, and the alternating cycle continues.

[0079] For the other group of cylinders, the work form is the same as above, but because the crankshafts differ by 180°, they work alternately. When one group of cylinders is in the power stroke, the other group of cylinders is in the exhaust stroke, alternately providing torque.

[0080] Wherein, the pressure of the compressed gas medium is 1Mpa to 50Mpa; the temperature of the high-temperature arc is 2000 to 8000 Kelvin.

[0081] Efficiency comparison ratio:

[0082] Fuel engine: Assume the engine cylinder diameter is 80mm, the stroke is 90mm, and the piston area is 50mm 2 , the displacement is 450ml, the intake pressure is 0.1Mpa, the compression ratio is 10:1, the pressure after compression is 1Mpa, and the pressure after the atomized fuel is burned and expanded in the combustion chamber is 5Mpa, minus the exhaust pressure of 0.1Mpa, which is equal to 4.9Mpa. 4.9Mpa is approximately equal to a force of 490N, 490×50mm 2 Equal to 24500N, divided by 9.8 is approximately equal to 2500KG force.

[0083] This storage engine: Assume that the engine cylinder diameter is 80mm, the stroke is 90mm, and the piston area is 50mm 2 , the intake compressed air pressure is 10Mpa, the arc temperature is 6000 Kelvin, the pressure after high temperature expansion is 40Mpa, minus the exhaust pressure of 10Mpa, equal to 30Mpa, 30Mpa is approximately equal to 3000N force, 3000×50mm 2 Equal to 150000N, divided by 9.8 is approximately equal to 15306KG of force.

[0084] The force of the fuel engine compressing the air is almost equal to the work consumed by the electric arc of the pressure storage engine. The efficiency of the pressure storage engine is 6 times higher than that of the fuel engine. The greater the compressed air pressure, the greater the engine power can be.
