Description

Technical Field

[0001] The present invention relates to the field of internal combustion engines, and in particular to a compressive internal combustion device and method. Background Art

[0002] An internal combustion engine is a power machine that burns fuel inside the machine and converts the heat energy released directly into power. There are many types of internal combustion engines, such as reciprocating piston internal combustion engines, rotary piston engines, free piston engines, rotary impeller gas turbines, jet engines, etc. The most common internal combustion engine is a piston internal combustion engine, whose working principle is that fuel and air are mixed and burned in its cylinder. The heat energy released causes high-temperature and high-pressure gas to be generated in the cylinder. The gas expands and pushes the piston to do work, and then the mechanical work is output through the crank-connecting rod mechanism or other mechanisms to drive the driven machine to work; the working principle of the jet engine is to use Newton's third law to accelerate and discharge the high-temperature and high-pressure gas generated after combustion, so that the gas is ejected at high speed to generate power.

[0003] As we all know, the volume of the current internal combustion engine cylinder is fixed, and it will continue to bear the impact of the explosion, which can easily damage the internal combustion engine cylinder, thus shortening the life of the internal combustion engine; and, since the volume of the cylinder is fixed, the high-temperature and high-pressure gas generated by combustion can only do work to the outside through the pressure of the gas, that is, it can only output kinetic energy through the high-pressure gas inside the cylinder, and there is a lack of explosive power and stable continuity. Therefore, an internal combustion device with a variable cylinder volume is proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a compressible internal combustion device and method to address the above-mentioned problems, which can effectively reduce the impact on the cylinder of the internal combustion device and reduce the possibility of damage to the cylinder; and improve the explosive power and sustainability of the internal combustion device.

[0005] The technical solution adopted by the present invention is as follows: a compressive internal combustion device includes a main cylinder body, which is composed of a fixed cylinder body and a movable cylinder body; one end of the fixed cylinder body is a fixed end, and the other end of the fixed cylinder body is a connecting end; one end of the movable cylinder body is an injection end, and the other end of the movable cylinder body is a sliding end; the sliding end and the connecting end are sealed and slidably connected so that the fixed cylinder body and the movable cylinder body are coaxially slidably connected, and the sliding stroke direction of the movable cylinder body is parallel to the axis of the main cylinder body; a plurality of elastic parts are arranged between the fixed cylinder body and the movable cylinder body, and the plurality of elastic parts are arranged along the axis of the main cylinder body; a fuel inlet, an oxidant inlet and an ignition needle are arranged on the fixed end; an injection hole is opened on the injection end; there is a support rod located in the main cylinder body, and one end of the support rod is fixed to the fixed cylinder body, and the other end of the support rod has a plugging head for plugging the injection hole.

[0006] Furthermore, a sealing groove is provided on the connecting end of the fixed cylinder body, a sealing ring is installed in the sealing groove, and the sealing ring is pressed by the sliding end of the movable cylinder body.

[0007] Furthermore, an annular countersunk groove is provided at the connecting end of the fixed cylinder body, and the sliding end of the movable cylinder body is inserted into the countersunk groove to realize a sliding connection between the sliding end and the connecting end; or an annular groove is provided on the outer wall of the fixed cylinder body, and the sliding end of the movable cylinder body is located in the annular groove and is slidably connected to the annular groove to realize a sliding connection between the sliding end and the connecting end.

[0008] Furthermore, the elastic member is located in the countersunk groove or the annular groove.

[0009] Furthermore, the shape of the fixed end is a cone protruding outward from the main cylinder body, and the fuel inlet, the combustion-supporting agent inlet and the ignition needle are all arranged on the tapered fixed end.

[0010] Further, the number of the injection hole is one, and the axis of the injection hole is colinear with the axis of the main cylinder body; or the number of the injection holes is multiple, and the multiple injection holes are arranged in a circumferential direction around the axis of the main cylinder body.

[0011] Furthermore, the injection end is in the shape of a cone protruding outward from the main cylinder body.

[0012] Furthermore, the plugging head is hemispherical in shape, and the diameter of the plugging head is greater than the diameter of the injection hole.

[0013] Furthermore, the elastic member is a tension spring.

[0014] A compressive internal combustion method, using the compressive internal combustion device, comprises the following steps:

[0015] S1: The fuel enters the main cylinder from the fuel inlet, and the combustion aid enters the main cylinder from the combustion aid inlet; the ignition needle ignites, and the fuel burns to generate high-temperature and high-pressure gas;

[0016] S2: The high-temperature and high-pressure gas expands, pushing the movable cylinder away from the fixed cylinder and stretching the elastic member. The impact force generated by the expansion of the high-temperature and high-pressure gas is converted into the elastic potential energy of the elastic member until the plug is separated from the injection hole and the high-temperature and high-pressure gas is ejected from the injection hole.

[0017] S3: In step S2, since it takes time for the injection port to eject the high-temperature and high-pressure gas, the pressure potential energy of the high-temperature and high-pressure gas is still greater than the sum of the elastic potential energies of the elastic parts at this time; that is, after step S2, the high-temperature and high-pressure gas will continue to push the movable cylinder away from the fixed cylinder, and the high-temperature and high-pressure gas will continue to eject; the pressure of the high-temperature and high-pressure gas in the total cylinder will decrease, and the elastic potential energy of the elastic parts will increase until the pressure potential energy of the high-temperature and high-pressure gas is equal to the sum of the elastic potential energies of the elastic parts;

[0018] S4: The high-temperature and high-pressure gas continues to be ejected, and the pressure of the high-temperature and high-pressure gas is reduced again. The elastic potential energy of the elastic member is released, and the movable cylinder is pulled close to the fixed cylinder, compressing the high-temperature and high-pressure gas in the main cylinder, so that the high-temperature and high-pressure gas in the main cylinder maintains a high-pressure state, and the ejection speed of the high-temperature and high-pressure gas does not drop significantly; until the movable cylinder is reset;

[0019] S5: Repeat steps S1-S4 to generate continuous, stable-flow-rate high-temperature and high-pressure gas jet power.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] The present invention enables the movable cylinder body to slide relative to the fixed cylinder body, so that the volume of the total cylinder body can be adaptively changed. Combined with the buffering capacity of the elastic member, the impact on the cylinder body of the internal combustion device can be effectively reduced, and the possibility of damage to the cylinder body can be reduced. When buffering the expansion impact of the high-temperature and high-pressure gas, the elastic member will also store energy so that it has elastic potential energy. The elastic potential energy is released in the late stage of the high-temperature and high-pressure gas injection (the pressure potential energy of the high-temperature and high-pressure gas is lower than the sum of the elastic potential energies of the elastic members), so that the high-temperature and high-pressure gas in the total cylinder body maintains a high-pressure state, and the injection speed of the high-temperature and high-pressure gas will not show a significant decrease, thereby improving the explosive power and sustainability of the internal combustion device.

[0029] Example 1

[0030] like Figure 1-Figure 2 As shown, a compressive internal combustion device includes a main cylinder body, which is composed of a fixed cylinder body 1 and a movable cylinder body 2; one end of the fixed cylinder body 1 is a fixed end 11, which is used to fix the fixed cylinder body 1 on the machine, and the fixed end 11 is a closed end; the other end of the fixed cylinder body 1 is a connecting end 12, and the connecting end 12 is an open end; one end of the movable cylinder body 2 is an injection end 22, and the injection end 22 is a closed end; the other end of the movable cylinder body 2 is a sliding end 21, and the sliding end 21 is an open end; the sliding end 21 is sealed and slidably connected with the connecting end 12, on the one hand, so that the fixed cylinder body 1 and the movable cylinder body 2 are coaxially slidably connected, on the other hand, the movable cylinder body 2 and the fixed cylinder body 1 use other cylinders to close their own openings, so that the fixed cylinder body 1 and the movable cylinder body 2 form a complete and interconnected whole; the sliding stroke direction of the movable cylinder body 2 is parallel to the axis of the main cylinder body, that is, the movable cylinder body 2 can move away from the fixed cylinder body 1 and close to the fixed cylinder body 1, so that the internal volume of the main cylinder body can be changed. The internal volume of the main cylinder can be changed, so that the main cylinder can adapt to the expansion of high-temperature and high-pressure gas, increase the flexibility of the main cylinder, and avoid hard impact on the main cylinder when the high-temperature and high-pressure gas expands.

[0031] In this embodiment, a plurality of elastic members 4 are arranged between the fixed cylinder body 1 and the movable cylinder body 2, and the plurality of elastic members 4 are arranged along the axis of the main cylinder body; the energy generated by the expansion of the high-temperature and high-pressure gas can be buffered in the elastic members 4 to form elastic potential energy; that is, after the movable cylinder body 2 is pushed by the expansion of the high-temperature and high-pressure gas, the movable cylinder body 2 moves away from the fixed cylinder body 1, and the elastic member 4 is deformed to have elastic potential energy; the elastic potential energy has at least the following effects:

[0032] First: cooperate with the sliding of the movable cylinder 2 to buffer the impact force of the high-temperature and high-pressure gas when it expands, and reduce the hard impact on the main cylinder;

[0033] Second: the subsequent release of elastic potential energy, that is, the elastic potential energy is released when the pressure potential energy of the high-temperature and high-pressure gas is lower than the sum of the elastic potential energy of the elastic member 4, providing energy for the high-temperature and high-pressure gas to maintain a stable high-flow rate injection in the later stage of injection;

[0034] Thirdly, the movable cylinder 2 is reset to prepare for the next injection of high-temperature and high-pressure gas.

[0035] In this embodiment, a fuel inlet 6, an oxidant inlet 7 and an ignition needle 8 are provided on the fixed end 11; wherein, the fuel inlet 6 can be connected to an external fuel storage tank, the oxidant inlet 7 can be connected to an external oxidant storage tank or air, and the ignition needle 8 can be connected to an external power supply, so as to enable continuous ignition; of course, check valves are provided at the fuel inlet 6 and the oxidant inlet 7 to prevent high-temperature and high-pressure gas generated by fuel combustion from flowing out of the main cylinder body from the fuel inlet 6 and the oxidant inlet 7.

[0036] It should be noted that the fuel can be gasoline or hydrogen; the combustion aid can be air or oxygen; in the present embodiment, the fuel is preferably hydrogen, the combustion aid is preferably oxygen, and the high-temperature and high-pressure gas generated is water vapor, which can achieve zero pollutant emissions.

[0037] In this embodiment, an injection hole 23 is provided on the injection end 22, and the high-temperature and high-pressure gas generated by combustion is ejected from the injection hole 23 to form a high-speed airflow. The kinetic energy of the airflow can be used to obtain power. If fan blades are installed at the injection hole 23, high-speed rotation movement can be obtained, which can be used in fields such as power generation.

[0038] In this embodiment, there is a support rod 3 located in the main cylinder body, and one end of the support rod 3 is fixed on the fixed cylinder body 1, and the other end of the support rod 3 has a plugging head 31, which can block the injection hole 23 to prevent external impurities from entering the cylinder body from the injection hole 23 and affecting the normal combustion of the cylinder body.

[0039] In summary, the present invention enables the movable cylinder body 2 to slide relative to the fixed cylinder body 1, so that the volume of the total cylinder body can be adaptively changed. Combined with the buffering capacity of the elastic member 4, the impact on the cylinder body of the internal combustion device can be effectively reduced, and the possibility of damage to the cylinder body can be reduced; when buffering the expansion impact of the high-temperature and high-pressure gas, the elastic member 4 will also store energy so that it has elastic potential energy, which is released in the later stage of the high-temperature and high-pressure gas injection (the pressure potential energy of the high-temperature and high-pressure gas is lower than the sum of the elastic potential energies of the elastic member 4), so that the high-temperature and high-pressure gas in the total cylinder body maintains a high-pressure state, and the injection speed of the high-temperature and high-pressure gas will not decrease significantly, thereby improving the explosive power and sustainability of the internal combustion device.

[0040] Of course, there can be multiple compressive internal combustion devices at the same time, running alternately to improve the continuous kinetic energy output and make up for the problem of intermittent power output.

[0041] Example 2

[0042] Based on Example 1, a specific implementation method that can be implemented is further proposed.

[0043] A feasible implementation manner is that a sealing groove is provided on the connecting end 12 of the fixed cylinder body 1. The sealing groove is annular and is colinear with the axis of the main cylinder body. A sealing ring 5 is installed in the sealing groove. The sealing ring 5 is pressed by the sliding end 21 of the movable cylinder body 2, that is, the sealing ring 5 can achieve sealing between the movable cylinder body 2 and the fixed cylinder body 1, and will not affect the sliding of the movable cylinder body 2 relative to the fixed cylinder body 1.

[0044] Regarding the sliding connection between the fixed cylinder body 1 and the movable cylinder body 2, this embodiment proposes the following several feasible implementation methods.

[0045] The first implementation method, such as Figure 1 As shown, an annular countersunk groove 13 is provided at the connecting end 12 of the fixed cylinder body 1, and the axis of the countersunk groove 13 is colinear with the axis of the main cylinder body; the sliding end 21 of the movable cylinder body 2 is inserted into the countersunk groove 13 to realize the sliding connection between the sliding end 21 and the connecting end 12, that is, the countersunk groove 13 guides the sliding of the movable cylinder body 2 to limit.

[0046] In the first embodiment, the elastic member 4 is located in the countersunk groove 13 , one end of the elastic member 4 is fixedly connected to the groove bottom, and the other end of the elastic member 4 is fixedly connected to the movable cylinder body 2 .

[0047] The second implementation method, such as Figure 2 As shown, an annular groove 14 is provided on the outer wall of the fixed cylinder body 1, and the axis of the annular groove 14 is colinear with the axis of the main cylinder body; the sliding end 21 of the movable cylinder body 2 is located in the annular groove 14 and is slidably connected to the annular groove 14 to realize the sliding connection between the sliding end 21 and the connecting end 12, that is, the countersunk groove 13 is used to limit and guide the sliding of the movable cylinder body 2.

[0048] In the second embodiment, the elastic member 4 is located in the countersunk groove 13 , one end of the elastic member 4 is fixedly connected to the groove wall of the annular groove 14 , and the other end of the elastic member 4 is fixedly connected to the movable cylinder body 2 .

[0049] In the second embodiment, the annular groove 14 may be a “concave” type or a step type.

[0050] A feasible implementation manner is that the fixed end 11 of the fixed cylinder body 1 is shaped like a cone protruding out of the main cylinder body, and the fuel inlet 6, the combustion aid inlet 7 and the ignition needle 8 are all arranged on the conical fixed end 11. After the fuel and the combustion aid enter the main cylinder body, they will be temporarily stored in the conical space for a period of time (diffusion takes time), that is, the concentration of fuel and the combustion aid at the conical fixed end 11 is higher, and the fuel is more easily completely burned after ignition, and a larger amount of high-temperature and high-pressure gas is generated.

[0051] Regarding the injection hole 23, this embodiment proposes the following several feasible implementation methods.

[0052] In a first embodiment, the number of the injection hole 23 is one, and the axis of the injection hole 23 is colinear with the axis of the main cylinder body, so that the reaction force on the main cylinder body is along the axis of the main cylinder body, avoiding the generation of torque.

[0053] In a second embodiment, there are multiple injection holes 23, and the multiple injection holes 23 are arranged in a circumferential array along the axis of the main cylinder body. Similarly, the reaction force on the main cylinder body is along the axis of the main cylinder body to avoid the generation of torque.

[0054] Furthermore, when there is only one injection hole 23, the shape of the injection end 22 is a cone protruding toward the outside of the main cylinder body. The cone can converge the high-temperature and high-pressure gas, increase the injection speed, and enhance the thrust.

[0055] A feasible implementation method is that the plugging head 31 is shaped like an American football, and its front end is a hemispherical guiding end, which is convenient for the plugging head 31 to be inserted into the injection hole 23; the rear end is fixedly connected to the support rod 3, and there is a straight line segment between the front end and the rear end to delay the injection of the post-combustion gas, and the straight line segment can prolong the time for the plugging head 31 to be separated from the injection hole 23.

[0056] In a feasible implementation manner, the plugging head 31 is hemispherical in shape, and the diameter of the plugging head 31 is larger than the diameter of the injection hole 23 , so as to ensure that the plugging head 31 can stably and completely block the injection hole 23 .

[0057] In a feasible implementation manner, the elastic member 4 is a tension spring.

[0062] S3: In step S2, since it takes time for the injection port to eject the high-temperature and high-pressure gas, the pressure potential energy of the high-temperature and high-pressure gas is still greater than the sum of the elastic potential energies of the elastic member 4 at this time; that is, after step S2, the high-temperature and high-pressure gas will continue to push the movable cylinder 2 away from the fixed cylinder 1, and the high-temperature and high-pressure gas will continue to eject; the pressure of the high-temperature and high-pressure gas in the total cylinder body decreases, and the elastic potential energy of the elastic member 4 increases until the pressure potential energy of the high-temperature and high-pressure gas is equal to the sum of the elastic potential energies of the elastic member 4;

[0063] S4: The high-temperature and high-pressure gas continues to be ejected, and the pressure of the high-temperature and high-pressure gas is reduced again. The elastic potential energy of the elastic member 4 is released, and the movable cylinder body 2 is pulled close to the fixed cylinder body 1, and the high-temperature and high-pressure gas in the main cylinder body is compressed, so that the high-temperature and high-pressure gas in the main cylinder body maintains a high-pressure state, and the ejection speed of the high-temperature and high-pressure gas does not drop significantly; until the movable cylinder body 2 is reset;

[0064] S5: Repeat steps S1-S4 to generate continuous, stable-flow-rate high-temperature and high-pressure gas jet power.
