Description

Technical Field

[0002] With economic development and improved living standards, the popularity of cars has increased significantly. Traditional car engines usually use fuels such as gasoline or diesel for combustion. Although these fuels provide power, they also bring some negative effects. One of the negative effects is that the fuel combustion process produces exhaust gas, such as carbon oxides, nitrogen oxides and particulate matter. The exhaust gas will pollute the environment, especially in the case of urban congestion, the exhaust gas emissions will be greater, and these emissions pose a threat to air quality and human health.

[0003] In order to reduce the negative impact of exhaust emissions, it is necessary to develop new high-efficiency, low-emission engines, one of which is the HCCL engine, High Compression, Charge Cooling. The engine significantly reduces fuel consumption and exhaust emissions by increasing the compression ratio, using cooled intake air and achieving lean combustion. However, due to the incomplete match between the combustion characteristics of ordinary fuels and the requirements of HCCL engine design, the combustion is incomplete or unstable. The use of ordinary fuels in HCCL engines will cause vibrations and affect the stability of the engine. The above problems need to be solved. Summary of the invention

DETAILED DESCRIPTION

[0057] The following combination Figure 1-Figure 6 The present application is described in further detail. The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to be limiting.

[0058] Reference Figure 1 The present application relates to a mixed fuel preparation system, which specifically includes a high-pressure hydrogen preparation module 1, an oil storage control module 2, an oil inlet control module 3, a maker 4, a gas-liquid mixing component 5 and an electronically controlled pressure relief component 6;

[0059] Among them, the high-pressure hydrogen preparation module 1, the oil storage control module 2, the oil inlet control module 3 and the electronically controlled pressure relief component 6 are all connected to the maker 4, and the gas-liquid mixing component 5 is installed in the maker 4;

[0060] The fuel inlet control module 3 is used to store the fuel to be mixed and transport the fuel to the maker 4;

[0061] The electrically controlled pressure relief component 6 is used to detect the air pressure in the making device 4, evacuate the making device 4 before performing the preparation operation, and keep the air pressure in the making device 4 constant during the preparation operation;

[0062] The high-pressure hydrogen preparation module 1 is used to input high-pressure hydrogen into the gas-liquid mixing component 5;

[0063] The maker 4 is used to store the fuel being mixed;

[0064] The gas-liquid mixing component 5 is used to prepare hydrogen nanobubbles and mix the hydrogen nanobubbles with the fuel;

[0065] The oil storage control module 2 is used to store the mixed fuel when the maker 4 completes the preparation of the mixed fuel.

[0066] Specifically, in order to solve the problem of engine vibration caused by the mismatch between fuel combustion characteristics and the engine, the present application prepares a mixed fuel obtained by mixing fuel and hydrogen nanobubbles through a mixed fuel preparation system. The fuel of the present application can be a liquid fuel such as gasoline and diesel. The preparation system delivers the fuel to be mixed to the maker 4 through the oil inlet control module 3, and the electronically controlled pressure relief component 6 evacuates the maker 4. Under a vacuum environment, the high-pressure hydrogen preparation module 1 delivers hydrogen to the fuel in the maker 4, and the gas-liquid mixing component 5 mixes the high-pressure hydrogen and the fuel, and prepares the hydrogen into hydrogen nanobubbles during the mixing process, thereby mixing a mixture of fuel and hydrogen nanobubbles, and the mixed fuel is output to the maker 4. When the mixed fuel preparation in the maker 4 is identified to be completed, the mixed fuel is stored through the oil storage control module 2, and a mixed fuel containing 400 million to 700 million hydrogen nanobubbles per milliliter of liquid fuel is obtained, and a fuel with a higher combustion value is prepared, so that fuel consumption is saved, and the HCCL engine is adapted to improve working stability.

[0067] In the present application, the oil inlet control module 3 includes an oil storage tank and an oil inlet control submodule, and its main function is to accurately control the delivery amount and flow rate of the fuel. The fuel flow is monitored by sensors and control systems, and the oil inlet speed is adjusted as needed so that the appropriate volume of fuel is delivered to the maker 4 and can be evenly mixed in the maker 4. The design of the oil inlet control part includes a flow meter and an electric valve to achieve accurate control of fuel delivery, thereby ensuring the quality and stability of the mixed fuel.

[0068] The oil storage control module 2 includes an oil storage tank and an oil storage control submodule, which is responsible for the storage management of the mixed fuel. After the mixed fuel is prepared in the maker 4, the module will transfer it to a storage container equipped with an oil storage tank, an oil pump and a corresponding automatic control system, which is similar to the oil inlet control module 3, so that the mixed fuel remains stable during storage and reduces leakage or pollution. The oil storage control module 2 also monitors the state and quantity of the fuel so that the fuel can be effectively used and safely stored.

[0069] The electronically controlled pressure relief component 6 is used to control the pressure environment inside the maker 4. Specifically, the pressure inside the maker 4 is precisely adjusted through the electronic control system, so that the input of high-pressure hydrogen is reduced under the required vacuum state, thereby reducing the occurrence of the situation where the hydrogen and the original internal gas are mixed to reach the explosion content. When the pressure inside the maker 4 is too high, the electronically controlled pressure relief component 6 will automatically release excess gas according to the preset critical value to reduce the occurrence of equipment damage or risk events.

[0070] The high-pressure hydrogen preparation module 1 is responsible for generating and supplying high-pressure hydrogen so as to generate hydrogen nanobubbles in the gas-liquid mixing component 5 for mixing with the fuel. Hydrogen is first generated by electrolysis of water or other methods and stored in high-pressure gas cylinders. The module pressurizes the hydrogen to the required level through a compression system and is equipped with precise regulating valves and control systems to manage gas flow and pressure. It also includes a pressure sensor and a safety valve to improve safety during operation. The hydrogen delivered by high pressure enables the hydrogen to be converted into the form of nanobubbles, so that it can be effectively mixed in the fuel to generate hydrogen nanobubbles and optimize the combustion performance of the mixed fuel.

[0071] The high-pressure hydrogen preparation module 1 is capable of producing 15 MPa of high-pressure hydrogen. The high-pressure hydrogen is input from the middle of the gas-liquid mixing component 5 into the gas-liquid mixing component 5 through the middle connecting pipe or connecting piece. The gas pressure input into the gas-liquid mixing component 5 is 10-13 MPa, and then the gas-liquid mixing component 5 is cut to generate nanobubbles.

[0072] The maker 4 is used to store the fuel and hydrogen nanobubbles that are being mixed and prepared, and is used to mix the fuel and hydrogen nanobubbles into the final mixed fuel. First, the fuel to be mixed is received through the oil inlet control module 3, and a vacuum environment is created inside the maker 4 using the electronically controlled pressure relief component 6. In this environment, high-pressure hydrogen is transported to the maker 4 through the high-pressure hydrogen preparation module 1, and the high-pressure hydrogen is converted into a nanobubble form through the gas-liquid mixing component 5, and gas-liquid mixing is performed with the fuel. What is usually stored in the maker 4 is a mixed fuel whose nanobubble content has not yet reached the preset standard. The unprepared mixed fuel is input into the gas-liquid mixing component 5 for mixing, and finally a mixed fuel with higher combustion value and stability is formed. After the mixing is completed, the maker 4 transports the mixed fuel to the oil storage control module 2 for storage and subsequent use.

[0073] The gas-liquid mixing component 5 is arranged in the compression cylinder 41 of the maker 4. When it is necessary to prepare a mixed fuel, a certain amount of the fuel to be prepared is installed in the maker 4, and the fuel will cover the gas-liquid mixing component 5, so that the two ends of the gas-liquid mixing component 5 can respectively input and output the fuel, and then the hydrogen nanobubbles and fuel obtained and generated in the middle are mixed while being output at a certain speed, so that the fuel in the maker 4 is all fuel containing nanobubbles.

[0074] As one embodiment, the maker 4 includes a compression cylinder 41 and a bubble detection module 42. The compression cylinder 41 is provided with an oil inlet 411 and an oil outlet 412:

[0075] The gas-liquid mixing component 5 and the bubble detection module 42 are both installed in the compression cylinder 41, the oil inlet control module 3 is connected to the oil inlet 411, the oil storage control module 2 is connected to the oil outlet 412, and the electronically controlled pressure relief component 6 is installed in the compression cylinder 41;

[0076] The bubble detection module 42 is used to detect the hydrogen nano bubble content of the mixed fuel in the compression cylinder 41 .

[0077] Specifically, the compression cylinder 41 of the embodiment of the present application receives the fuel to be mixed through the oil inlet control module 3, and the compression cylinder 41 stores the fuel that needs to be mixed with the hydrogen nanobubbles, providing a cavity for the mixing of the fuel and the hydrogen nanobubbles.

[0078] Before the hydrogen nanobubbles and the fuel are mixed, the electronically controlled pressure relief component 6 evacuates the sealed compression cylinder 41, thereby removing other air inside and providing a vacuum environment inside.

[0079] During the process of mixing hydrogen nanobubbles and fuel, the gas-liquid mixing component 5 obtains fuel from the compression cylinder 41, which may be the initial fuel or the fuel being mixed, that is, the fuel mixed with some hydrogen nanobubbles, and the gas-liquid mixing component 5 outputs the internally mixed or further mixed fuel to the compression cylinder 41 for storage until the number of hydrogen nanobubbles in the mixed fuel in the compression cylinder 41 reaches a preset value.

[0080] The bubble detection module 42 detects the content of hydrogen nanobubbles in the fuel in the compression cylinder 41. The bubble detection module 42 uses a bubble counter, a dynamic light scattering instrument or an ultrasonic detector to detect hydrogen nanobubbles.

[0081] Among them, the bubble counter detects the number and size of bubbles in the liquid through optical or electrical principles, such as a bubble counter that detects changes in electrical conductivity.

[0082] The dynamic light scattering instrument uses laser to measure the scattered light of bubbles in the liquid, thereby determining the size distribution and quantity of the bubbles, and sending the information to the controller in real time, thereby controlling the start and stop of the high-pressure hydrogen preparation module 1 through the controller.

[0083] Since bubbles in the ultrasonic detector affect the speed and attenuation of ultrasonic waves, the bubbles are detected and counted by changing the propagation characteristics of the ultrasonic signal, thereby realizing the detection of hydrogen nanobubbles in the fuel in the compression cylinder 41.

[0084] As one implementation mode, the making device 4 further includes a temperature module, and the temperature module is installed on the compression cylinder 41 .

[0085] Specifically, the embodiment of the present application uses a temperature module to obtain the fuel temperature data in the compression cylinder 41, so as to know the temperature of the storage and mixing environment of the hydrogen nanobubbles. Then, the ambient temperature in the compression cylinder 41 is controlled according to the temperature module to adjust to a temperature range suitable for the storage of hydrogen nanobubbles.

[0086] Among them, the temperature threshold is the standard temperature range, and the standard temperature range is set to 15℃~25℃. The solubility of hydrogen nanobubbles in gasoline is affected by temperature. Although hydrogen is more soluble at lower temperatures, too low a temperature will thicken the fuel, such as gasoline, affecting the fluidity and atomization effect of the fuel in the engine. Engines are usually designed to run at ambient temperature. The temperature range of 15℃ to 25℃ helps ensure that the gasoline maintains a suitable temperature before entering the engine, thereby optimizing combustion efficiency and engine performance. The storage temperature range of 15℃ to 25℃ provides a balance point for mixed gasoline, which takes into account the solubility of hydrogen and maintains the fluidity and safety of gasoline. It also helps to maintain the chemical stability of the oil and the performance of the engine, so that the mixed fuel maintains the stability of the bubbles while maintaining the physical properties of the fuel, which is conducive to the mixing and storage of hydrogen nanobubbles with the fuel.

[0087] As one embodiment, the gas-liquid mixing assembly includes a first through pipe 51, a second through pipe 52, a third through pipe 53 and a fourth through pipe 54, and the third through pipe 53 is provided with a mixing channel 531 and a bubble punching hole 532;

[0088] The first through-tube 51 and the second through-tube 52 are fixedly connected to the two ends of the third through-tube 53, the mixing channel 531 runs through the two ends of the third through-tube 53, the first through-tube 51 and the second through-tube 52 are both connected to the mixing channel 531, the fourth through-tube 54 is fixedly connected to the side wall of the third through-tube 53, the two ends of the fourth through-tube 54 are respectively connected to the gas outlet of the high-pressure hydrogen preparation module 1 and the bubble punching hole 532, and the bubble punching hole 532 is connected to the mixing channel 531;

[0089] The first through pipe 51 is used to pass the fuel into the mixing channel 531;

[0090] The second through pipe 52 is used to output the mixed hydrogen nanobubbles and fuel to the generator 4;

[0091] The bubble punching hole 532 is used to spray high-pressure hydrogen into the mixing channel 531;

[0092] The mixing channel 531 is used to mix the hydrogen nanobubbles and the fuel.

[0093] Specifically, refer to Figure 2 and Figure 3 The side wall of the third through pipe 53 of the embodiment of the present application is installed on the inner wall of the compression cylinder 41 by a fixed connection. There are many fixing methods, which are not limited in the embodiment of the present application.

[0094] The fourth through-tube 54 is used to connect the output pipe or output member of the high-pressure hydrogen preparation module 1, and the output pipe or output member passes through the top or inner wall of the compression cylinder 41 and is connected to the fourth through-tube 54. The fourth through-tube 54 provides a fixed connection end for the output pipe or output member, which can be a fixed connection such as a threaded connection or a clamping connection.

[0095] In one embodiment, the outer wall of the fourth through pipe 54 is provided with a thread, the output pipe of the high-pressure hydrogen preparation module 1 is used to connect to one end of the fourth through pipe 54 and is provided with a rotatable connector, and the output pipe is used to connect to one end of the fourth through pipe 54 and is provided with an internal thread, and a threaded connection is performed through the outer wall thread of the fourth through pipe 54 and the inner wall thread of one end of the output pipe used to connect to the fourth through pipe 54.

[0096] The high-pressure hydrogen preparation module 1 allows the high-pressure hydrogen to enter the third through pipe 53 from the fourth through pipe 54 , and reduces the high-pressure hydrogen to a certain volume through the bubble punching holes 532 and discharges it into the mixing channel 531 . The mixing channel 531 is provided with a plurality of groups of bubble punching holes 532 .

[0097] One embodiment is that two groups of bubble punching holes 532 are provided in the mixing channel 531, each group of bubble punching holes 532 is provided with an equal number of micro-punching holes, and the two groups of bubble punching holes 532 are respectively arranged in opposite positions on the inner wall of the mixing channel 531. When the high-pressure hydrogen reaches the mixing channel 531 after passing through the fourth through pipe 54 and the bubble punching holes 532, the micro-punching holes arranged in opposite positions enable the ejected high-pressure hydrogen to achieve hedging, and the hedging and cutting form hydrogen nano-bubbles under the condition of providing a pressure of 10-13 MPa on one side, thereby forming hydrogen nano-bubbles in the mixing channel 531. And because the hedging exerts an outward thrust in the mixing channel 531, that is, the high-pressure hydrogen and the nano-bubbles exert a thrust in the mixing channel 531, so that the fuel can be output or discharged from the first through pipe 51 and the second through pipe 52, and the mixing of the fuel and the hydrogen nano-bubbles is achieved in the mixing channel 531.

[0098] The hollow parts of the first through pipe 51 , the second through pipe 52 and the third through pipe 53 are arranged on a horizontal line, so that the fuel can smoothly enter the mixing channel 531 or be smoothly discharged to the compression cylinder 41 .

[0099] As one embodiment, the bubble punching hole 532 includes a main punching hole 5321, a plurality of branch punching holes 5322 and a plurality of first branch airways 5323;

[0100] Among them, the main punching hole 5321 and the branch punching hole 5322 are arranged at intervals along the length direction of the third through pipe 53, the main punching hole 5321 connects the fourth through pipe 54 and the mixing channel 531, one end of the branch punching hole 5322 is connected to the mixing channel 531, the other end of the branch punching hole 5322 is connected to one end of the first branch airway 5323, and the other end of the first branch airway 5323 is connected to the side wall of the main punching hole 5321.

[0101] Specifically, in order to improve the efficiency of mixing the fuel and hydrogen nanomolecules in the mixing channel 531, each group of bubble punching holes 532 of the embodiment of the present application is provided with a main punching hole 5321 and a branch punching hole 5322. The bubble punching hole 532 is specifically composed of a main punching hole 5321 and a plurality of branch punching holes 5322, and the main punching hole 5321 directly connects the fourth through pipe 54 and the mixing channel 531. When the fourth through pipe 54 receives the high-pressure hydrogen from the high-pressure hydrogen preparation module 1, the main punching hole 5321 directly transports the high-pressure hydrogen to the mixing channel 531 for hedging.

[0102] The branch punching hole 5322 is connected to the side wall of the main punching hole 5321 through the first branch air channel 5323, and is connected to the mixing pipe. When the high-pressure hydrogen is delivered to the main punching hole 5321, the high-pressure hydrogen is also delivered to the branch punching hole 5322 through the first branch air channel 5323, and then delivered to the designated place in the mixing channel 531 through the branch punching hole 5322 for counter-attack, generating hydrogen nanobubbles.

[0103] In one embodiment, the embodiment of the present application has one main punch hole 5321 , two branch punch holes 5322 , and two first branch airways 5323 corresponding to the branch punch holes 5322 are also provided.

[0104] The main punching hole 5321 is disposed in the middle portion of the third through tube 53 and communicates with the hollow portion of the fourth through tube 54 .

[0105] The two branch punching holes 5322 are spaced apart from the main punching hole 5321, and the two branch punching holes 5322 are respectively arranged at both ends of the main punching hole 5321, that is, the main punching hole 5321 and the branch punching holes 5322 are spaced apart along the length direction of the third through pipe 53. By setting the above method, a high-pressure hydrogen gas source can be divided into a plurality of tiny punching holes for output, so that sufficient nanobubbles can be generated in the mixing channel 531, and it is not limited by the number of input sources. Only one input source is needed to complete the work of multiple punching holes, and the high-pressure hydrogen is fully utilized for fuel mixing.

[0106] As one embodiment, at least two groups of bubble punching holes 532 are provided, and the bubble punching holes 532 are also provided with a second branch airway 5324;

[0107] The bubble punching holes 532 are arranged at intervals around the side wall of the third through pipe 53 . The second branch air channels 5324 are arranged on the side wall of the third through pipe 53 . The second branch air channels 5324 are connected to the main punching holes 5321 of several groups of bubble punching holes 532 .

[0108] Specifically, in the embodiment of the present application, when two or more groups of bubble punching holes 532 are provided, each group of bubble punching holes 532 is connected through the second branch airway 5324 .

[0109] Specifically, the main punching hole 5321 of the first group of bubble punching holes 532 is directly connected to the fourth through pipe 54, so as to directly obtain high-pressure hydrogen for hedging, and the branch punching holes 5322 of the first group of bubble punching holes 532 obtain high-pressure hydrogen for hedging from the main punching hole 5321 through the first branch air channel 5323.

[0110] The main punching holes 5321 of the second group of bubble punching holes 532 are connected to the mixing channel 531, and the main punching holes 5321 of the second group of bubble punching holes 532 are connected to the main punching holes 5321 of the first group of bubble punching holes 532 through the second branch air channel 5324, so that the main punching holes 5321 of the second group of bubble punching holes 532 obtain high-pressure hydrogen from the main punching holes 5321 of the first group of bubble punching holes 532 for counter-punching.

[0111] The branch punching holes 5322 of the second group of bubble punching holes 532 obtain high-pressure hydrogen from the main punching holes 5321 of the second group of bubble punching holes 532 through the first branch air channel 5323 of the second group of bubble punching holes 532, so that the main punching holes 5321 and the branch punching holes 5322 of the second group of bubble punching holes 532 can output high-pressure hydrogen.

[0112] The positions of the main punching holes 5321 and the branch punching holes 5322 of the first and second groups of bubble punching holes 532 are correspondingly arranged, that is, when the first and second groups of bubble punching holes 532 both output high-pressure hydrogen, the high-pressure hydrogen of the corresponding punching holes of the two groups of bubble punching holes 532 can collide with each other in the fuel in the mixing channel 531, thereby realizing the cutting of hydrogen and preparing hydrogen nanobubbles, and the hydrogen nanobubbles are fully mixed with the fuel under the action of force, so that when the mixed fuel is used, the combustion value is continuously released by secondary ignition of the hydrogen nanobubbles in the fuel, so that the engine can continue to operate stably.

[0113] As one embodiment, the third through-tube 53 includes a through-tube outer part 533 and a through-tube inner part 534, and the through-tube outer part 533 is provided with a nested channel 5331;

[0114] Among them, the bubble punching hole 532 is set through the side walls of the through-tube outer part 533 and the through-tube inner part 534, the mixing channel 531 passes through both ends of the through-tube inner part 534, the nested channel 5331 passes through both ends of the through-tube outer part 533, and the through-tube inner part 534 is slidably connected to the nested channel 5331.

[0115] Specifically, the third through-tube 53 of the embodiment of the present application is assembled from a through-tube outer component 533 and a through-tube inner component 534 . The detachable design of the inner and outer components facilitates the shape design and processing of the bubble punching hole 532 .

[0116] Among them, the main punching hole 5321 and the branch punching hole 5322 are opened perpendicularly to the wall surface of the third through pipe 53, so they can be directly grooved during processing. However, the first branch airway 5323 and the second branch airway 5324 are set horizontally to the wall surface of the third through pipe 53 and are located inside the side wall of the third through pipe 53. Therefore, the embodiment of the present application is divided into two parts: the through pipe outer part 533 and the through pipe inner part 534, which can divide the first branch airway 5323 and the second branch airway 5324 into two halves.

[0117] Half of the first branch air channel 5323 and the second branch air channel 5324 are arranged in the form of grooves on the inner wall of the through-tube outer member 533, and the other half of the first branch air channel 5323 and the second branch air channel 5324 are arranged in the form of grooves on the surface of the through-tube inner member 534. The processing difficulty of the third through-tube 53 is further reduced, thereby reducing the difficulty of preparing hydrogen nanobubbles, enhancing the economic benefits brought by them, and improving the feasibility of preparing mixed fuel by mixing hydrogen nanobubbles into fuel, thereby improving the practicality of the present application.

[0118] Furthermore, the cross-sectional area of ​​the mixing passage can be changed by the passage inner part 534, thereby changing the size of the mixing passage 531. Mixing passages 531 of different sizes can adjust the preparation rate of the mixed fuel and the generation effect of hydrogen nanobubbles.

[0119] For example, by changing the size of the mixing channel 531 and adjusting the relative distances between the groups of bubble punching holes 532, the size of the generated hydrogen nanobubbles can be adjusted, so that the mixed gasoline can be prepared to have a content suitable for use in different engines, thereby improving the adaptability of the prepared mixed gasoline.

[0120] The nesting channel 5331 is a hollowed-out portion slightly larger than the volume of the through-tube inner component 534 , so that the through-tube inner component 534 can be slidably connected in the through-tube outer component 533 for assembly.

[0121] As one embodiment, the main punching hole 5321 includes a first sub-hole 53211 and a second sub-hole 53212 . The first sub-hole 53211 passes through the through-tube outer component 533 , and the second sub-hole 53212 passes through the through-tube inner component 534 .

[0122] The first branch airway 5323 includes a first airway groove 53231 and a second airway groove 53232 . The first airway groove 53231 is disposed on the through-tube outer component 533 , and the second airway groove 53232 is disposed on the through-tube inner component 534 .

[0123] The second branch airway 5324 includes a third airway groove and a fourth airway groove. The third airway groove is provided on the through-tube outer component 533 , and the fourth airway groove is provided on the through-tube inner component 534 .

[0124] Specifically, refer to Figure 4 In the embodiment of the present application, the first sub-hole 53211, the first airway groove 53231 and the third airway groove are respectively used as the main punching hole 5321, the first branch airway 5323 and the second branch airway 5324, and half of the slots are arranged on the outer part 533 of the through-tube, and the second sub-hole 53212, the second airway groove 53232 and the fourth airway groove are respectively used as the main punching hole 5321, the first branch airway 5323 and the second branch airway 5324, and the other half of the slots are arranged on the inner part 534 of the through-tube.

[0125] When the inner part 534 of the through-tube is installed to the preset position of the inner nested channel 5331, the first sub-hole 53211 and the second sub-hole 53212 are combined into the main punching hole 5321, the first airway groove 53231 and the second airway groove 53232 are combined into the first branch airway 5323, and the third airway groove and the fourth airway groove are combined into the second branch airway 5324.

[0126] As one embodiment, the third through pipe 53 further includes a limiting abutment plate 535, and the limiting abutment plate 535 is provided with an abutment plate through hole 5351;

[0127] The limiting abutment plate 535 is fixedly connected to the through-tube outer member 533 for connecting to one end of the second through-tube 52 , and the abutment plate through hole 5351 communicates with the mixing channel 531 and the second through-tube 52 .

[0128] Specifically, the limiting abutment plate 535 in the embodiment of the present application is used to limit the position of the through-tube inner component 534 in the nesting channel 5331. When the through-tube inner component 534 is installed in the nesting channel 5331, the through-tube inner component 534 passes through the hollow portion of the first through-tube 51 to reach the nesting channel 5331, that is, when the through-tube inner component 534 and the nesting channel 5331 have the same shape, the cross-sectional area of ​​the hollow portion of the first through-tube 51 is greater than or equal to the cross-sectional area of ​​the nesting channel 5331. When the through-tube inner component 534 is slidably connected in the nesting channel 5331, one end of the through-tube inner component 534 abuts against the limiting abutment plate 535, so that the through-tube inner component 534 is slidably installed to a suitable position without exceeding the nesting channel 5331.

[0129] The other end of the through-tube inner component 534 of the embodiment of the present application, that is, the end away from the limiting stop plate 535 , is detachably fixedly mounted on the through-tube outer component 533 .

[0130] As one of the embodiments, the first through pipe 51 is installed with a one-way valve assembly 55 for allowing the fuel to flow from the first through pipe 51 to the second through pipe 52 in a one-way direction, wherein the one-way valve assembly 55 is provided with a connecting portion 551, the one-way valve assembly 55 is fixedly connected or integrally connected to the connecting portion 551, and the one-way valve assembly 55 is installed on the first through pipe 51 via the connecting portion 551.

[0131] Specifically, refer to Figure 5 The surface of the first through pipe 51 of the embodiment of the present application is provided with threads, and the inner wall of the connecting portion 551 of the one-way valve assembly 55 is provided with threads. Through the mutual cooperation of the threads, the connecting portion 551 of the one-way valve assembly 55 is fixedly connected to the surface of the first through pipe 51.

[0132] As one implementation manner, an abutment sheet 552 is disposed in the connection portion 551 , and one end of the abutment sheet 552 is fixedly connected to the one-way valve assembly 55 .

[0133] Specifically, the abutment sheet 552 is located in the middle hollow portion of the connecting portion 551, and the volume of the abutment sheet 552 is smaller than the connecting portion 551, that is, the abutment sheet 552 and the connecting portion 551 are spaced apart, and the side wall length of the abutment sheet 552 is longer than the side wall length of the connecting portion 551, so that the abutment sheet 552 away from the end for fixing the one-way valve assembly 55 can extend into the hollow portion of the first through pipe 51, so that when the connecting portion 551 is installed in the first through pipe 51, the abutment sheet 552 abuts against one end of the through pipe inner component 534 to further fix the through pipe inner component 534.

[0134] The abutment plate through hole 5351 of the embodiment of the present application is usually set to be circular, and the cross-section of the through-tube inner component 534 is also usually set to be circular, wherein the size of the abutment through hole is smaller than the cross-section of the through-tube inner component 534 compared with the cross-section size of the through-tube inner component 534, so that the through-tube inner component 534 will not slide out of the abutment through hole.

[0135] As one implementation manner, the through-tube outer component 533 is provided with a first sliding groove 5332 , and the through-tube inner component 534 is provided with a first sliding member 5341 for being limited in the first sliding groove 5332 .

[0136] Specifically, the first sliding member 5341 in the embodiment of the present application is fixedly connected or integrally connected to the outer side wall of the through-tube inner member 534. The inner wall of the through-tube outer member 533, that is, the side wall of the nested channel 5331, is provided with a first sliding groove 5332 corresponding to the shape of the first sliding member 5341, so that when the through-tube inner member 534 is installed in the through-tube outer member 533, it can be installed at a suitable angle, so that the bubble punching hole 532 can be matched and connected.

[0137] Furthermore, when the nested channel 5331 and the inner channel component are cylindrical, the first sliding groove 5332 and the first sliding member 5341 can be limited so that the cylindrical inner channel component will not rotate in the outer channel component.

[0138] As one embodiment, the main punching holes 5321 and the branch punching holes 5322 are both arranged obliquely from the outer wall of the through-tube outer component 533 to the inner wall of the through-tube inner component 534 .

[0139] Specifically, the embodiment of the present application sets an inclined bubble punching hole 532 to achieve collision of more than two groups of bubble punching holes 532 at a reasonable position, and generates hydrogen nanobubbles of a preset range size and a preset range quantity through the coordination of the inclined setting and the distance of the bubble punching holes 532, thereby generating a mixed fuel that meets the use of the corresponding engine, thereby achieving a more stable and efficient combustion process, and improving the overall performance and reliability of the HCCL engine.

[0140] As one embodiment, one end of the bubble punching hole 532 close to the through-tube outer member 533 is inclined toward the first through-tube 51 , and one end of the bubble punching hole 532 close to the through-tube inner member 534 is inclined toward the second through-tube 52 .

[0141] Specifically, the embodiment of the present application tilts the end of the bubble punching 532 close to the outer tube part 533 toward the first tube 51, and tilts the end of the bubble punching 532 close to the inner tube part 534 toward the second tube 52, so as to provide a unidirectional thrust in the mixing channel 531, so that the generated hydrogen nanobubbles and the prepared mixed fuel can enter from the first tube 51 and be discharged from the second tube 52, so that the gas is always discharged from one end to the other end, reducing the occurrence of intermediate reversal. And the fuel is definitely discharged into the mixing channel 531 to a certain extent for mixing of bubbles and fuel, thereby improving the mixing efficiency.

[0142] Reference Figure 6 , a method for preparing a mixed fuel is provided for an embodiment of the present application, the system comprising:

[0143] Step S1: obtaining a start instruction. When the start instruction is obtained, sending fuel delivery information to the oil inlet control module 3 and sending vacuum information to the electronically controlled pressure relief component 6;

[0144] Step S2: obtaining the air pressure state information of the electronically controlled pressure relief component 6, and sending hydrogen delivery information to the high-pressure hydrogen preparation module 1 when the air pressure state information is vacuum;

[0145] Step S3: Acquire the bubble detection information of the maker 4, compare the bubble detection information with the preset bubble comparison range value, and send the fuel storage information to the oil storage control module 2 when the bubble detection information is within the bubble comparison range value.

[0146] Specifically, the mixed fuel preparation method of the present application is configured in the controller of the mixed fuel preparation system, and receives, processes and sends information to the other modules of the preparation system. When it is necessary to perform mixed fuel preparation, the controller obtains the start instruction, thereby controlling the oil inlet control module 3 to perform the corresponding fuel delivery operation, so that the fuel to be mixed is transferred to the compression cylinder 41. After the transportation is completed, the controller sends a vacuum information to the electronically controlled pressure relief component 6, and the electronically controlled pressure relief component 6 extracts the air in the compression cylinder 41 until it is vacuumed.

[0147] The controller obtains the air pressure status information of the producer 4, which is the air pressure value in the current producer 4. When the current state is vacuum, the controller sends hydrogen transportation information to the high-pressure hydrogen preparation module 1, so that the high-pressure hydrogen preparation module 1 provides high-pressure hydrogen to the gas-liquid mixing component 5, and performs gas-liquid mixing on the fuel in the producer 4, specifically mixing hydrogen nanobubbles and fuel.

[0148] The controller obtains the bubble detection information of the maker 4, specifically the bubble detection information of the bubble detection module 42, and obtains the preset bubble comparison range value before that, and compares the bubble detection information with the bubble comparison range value at intervals. When the bubble detection information is detected to be within the bubble comparison range value, the fuel storage information is sent to the fuel storage control module 2.

[0149] When the oil storage control module 2 obtains the fuel storage information, it extracts the mixed fuel in the maker 4 and transports and transfers it to the storage cabin for storage.

[0150] As one implementation mode, it also includes:

[0151] After sending the hydrogen transportation information to the high-pressure hydrogen preparation module 1, the constant pressure threshold information is sent to the electronically controlled pressure relief component 6, and the electronically controlled pressure relief component 6 adjusts the pressure in the preparation device 4 within the mixed standard pressure range.

[0152] Specifically, the constant pressure threshold information of the embodiment of the present application is the optimal air pressure range information when the fuel mixing operation is performed in the compression cabin. During the fuel mixing process, the high-pressure hydrogen preparation module 1 needs to continuously deliver high-pressure hydrogen to the sealed maker 4. In the initial state, since the maker 4 is evacuated, the internal air pressure is far from reaching the pressure threshold. After a certain period of time, the internal air pressure gradually increases until it exceeds the pressure threshold. The electronically controlled pressure relief component 6 detects the current air pressure and determines whether the current air pressure exceeds the threshold based on the constant pressure threshold information. If it exceeds the threshold, the gas in the maker 4 is released, thereby achieving the effect of adjusting the pressure in the maker 4 to within the mixing standard pressure range.

[0153] The mixing standard pressure range is set to 5 to 10 times the atmospheric pressure, that is, 0.5 to 1 MPa. Higher pressure can increase the solubility of hydrogen in the liquid, which helps to form and maintain nanobubbles. Under high pressure, the solubility of hydrogen increases, and nanobubbles are more likely to exist stably.

[0154] The present application obtains fuel temperature data in the compression cylinder 41, learns the temperature of the storage and mixing environment of the hydrogen nanobubbles, and adjusts it to a standard temperature range.

[0155] Since high temperature increases the surface tension of bubbles, causing them to merge and dissipate faster, the standard temperature range is set at 15℃~25℃. The storage temperature range of 15℃ to 25℃ provides a balance point for mixed gasoline.

[0156] As one implementation manner, the bubble comparison range value is 400 million to 700 million hydrogen nanobubbles.

[0157] The embodiment of the present application provides a mixed fuel, including liquid fuel and hydrogen nanobubbles, wherein each milliliter of liquid fuel contains 400 million to 700 million hydrogen nanobubbles.

[0158] As one embodiment, the shape of the hydrogen nanobubbles is a spherical crown.

[0159] As one implementation manner, the radius of curvature of the hydrogen nanobubbles is 50 to 500 nanometers.

[0160] As one embodiment, the height of the hydrogen nanobubbles is 1 to 100 nanometers.

[0161] Specifically, the embodiment of the present application provides a mixed fuel, which contains 400 to 700 million hydrogen nanobubbles per milliliter of liquid fuel. Hydrogen nanobubbles refer to hydrogen bubbles with a size of nanometers. The diameter of hydrogen nanobubbles is usually less than or equal to 1000 nanometers. The bubbles are tiny bubbles formed by hydrogen molecules in the liquid. The high-density distribution of nanobubbles ensures the uniform mixing of hydrogen, which can significantly improve the combustion efficiency and stability of the fuel, thereby playing a role in adapting to the use of HCCL engines.

[0162] Among them, the spherical crown shape of the bubbles helps to stabilize the bubbles, reducing the risk of bubble aggregation or rupture, thereby maintaining a uniform mixing state.

[0163] The curvature radius of hydrogen nanobubbles is 50 to 500 nanometers. This curvature radius enables the bubbles to have a higher surface area ratio, increases the solubility and reactivity of hydrogen, and can improve the combustion speed and efficiency of the fuel.

[0164] The height of hydrogen nanobubbles is 1 to 100 nanometers. Keeping the height within this range can control the stability and uniformity of the bubbles so that they will not burst or aggregate too quickly during the combustion process.

[0165] The mixed fuel of the embodiment of the present application can improve the combustion efficiency and stability of the fuel by mixing liquid fuel with high-density hydrogen nanobubbles. The uniform distribution and appropriate size design of the hydrogen nanobubbles help optimize the combustion process, reduce fuel consumption, and improve the working stability of the engine.

[0166] In order to allow the hydrogen nanobubbles to be more stably mixed in the fuel, the mixed fuel of the present application adopts an environment of 5 to 10 times the atmospheric pressure, i.e., 0.5 to 1 MPa, and is stored in an environment with a temperature range of 15°C to 25°C. Higher pressure and appropriate temperature help to increase the storage time and stability of the bubbles.

[0167] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-described device and product can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here.

[0168] In several embodiments provided in this application, it should be understood that the disclosed methods, systems, devices and program products may be implemented in other ways.

[0169] In addition, each functional unit in each embodiment of the present application may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit. The above-mentioned integrated unit may be implemented in the form of hardware or in the form of software functional units.

[0170] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
