Abstract
Description
Technical Field
[0001] The present application relates to the field of internal combustion engines, and in particular to a novel engine combustion and power generation structure. Background Art
[0002] At present, pure fuel engines consume fuel energy, and their emissions pollute the environment. They are prone to carbon deposits during use, which leads to reduced engine performance, increased fuel consumption, increased exhaust emissions, increased engine wear and shortened service life. In plateau areas, due to lower atmospheric pressure and less oxygen content, engine combustion efficiency and power performance will decrease, fuel utilization will decrease, fuel consumption will increase, and engine stability will deteriorate.
[0003] Pure electric vehicles: long charging time, inconvenient facilities, limited battery life, high battery cost and reduced lifespan, energy sources and battery processing affect the environment, and batteries are flammable and explosive.
[0004] Plug-in hybrid vehicles: high battery cost and short life, inconvenient charging, reliance on fuel engines at high speeds, poor low-temperature performance, slow charging, high price, complex repair and maintenance, high fuel consumption when out of battery, and limited pure electric range.
[0005] Battery electric vehicles: Hydrogen preparation is difficult and costly, there are few hydrogen refueling stations, catalysts are scarce, hydrogen storage and transportation are dangerous, the technical threshold is high, the adaptability to plateaus is poor, and the body structure requirements are high.
[0006] Extended-range electric vehicles: low battery power and power attenuation, high maintenance cost, high energy consumption at high speeds, noise and vibration from the range extender and insufficient output, high price, and frequent charging.
[0007] The existing electrolyzer hydrogen and oxygen combustion-supporting method: the hydrogen and oxygen inlet pipe are unevenly mixed, resulting in local hydrogen richness or hydrogen deficiency, making the air-fuel ratio oxygen sensor signal unstable. At the same time, due to the different ignition points of oil and gas, the ignition time will be late or early, which has no obvious effect on reducing fuel consumption. On the contrary, it will increase fuel consumption and affect engine performance and stability.
[0008] Considering the above disadvantages of pure hydrogen energy: 1. Uneven mixing of engine gas can easily cause combustion problems, reducing the thermal efficiency of the engine; 2. Incomplete combustion during engine gas mixing reduces the flame propagation speed and stability. The mixing and combustion process of fuel and oxidant is not improved, which increases pollutant emissions. 3. The combustion process of the engine is complex; 4.

[0025] Compared with the prior art, the present invention has the following beneficial effects: (1) The combustion working structure of the present invention is equipped with an electrolysis device, which can use pure water to produce hydrogen and oxygen in real time, wherein oxygen enters the engine intake pipe through the first connecting pipe, and a high-oxygen content intake air of high-temperature plasma is generated by the plasma generator and the gas turbulence mechanism arranged in the intake pipe, and the intake air is stimulated to produce strong thermodynamic instability and eddy motion. The intake air further enters the hydrogen in the front section of the intake manifold through the second connecting pipe or the hydrogen mixed with the fuel through the second connecting pipe, and is mixed with the fuel in the engine cylinder for combustion, thereby enhancing the flame propagation speed and stability, so that the combustion process of the fuel is greatly improved; at the same time, under the action of the high calorific value of hydrogen, the fuel consumption is greatly reduced, the combustion reaction is more complete, and due to the mixing of fuel, hydrogen and oxygen, the engine can work at a high compression ratio, reduce local over-rich combustion, reduce and avoid the possibility of carbon deposit formation, and achieve full mixing and more complete combustion as a whole, improve the thermal efficiency of the engine, reduce the amount of fuel per stroke of the engine, increase power output, and reduce pollution emissions.
[0026] (2) Furthermore, in the combustion working structure of the present invention, hydrogen enters the engine intake pipe at the rear section of the gas turbulence mechanism through the second connecting pipe, is fully mixed with the intake air of the turbulent oxygen plasma, and is fully burned with the fuel in the engine cylinder, thereby solving the problem of uneven mixing and combustion based on a simple structure, improving fuel efficiency, increasing power output, and reducing pollution emissions.
[0027] (3) Furthermore, in the combustion working structure of the present invention, hydrogen enters the fuel injection system through the second connecting pipe, and a liquid-gas mixer and a liquid-gas atomizing mechanism are configured in the fuel injection system. The liquid-gas mixer allows hydrogen and fuel to be mixed in a preset ratio on the flow layer, and the liquid-gas atomizing mechanism allows hydrogen and fuel to be fully atomized, and finally sprayed into the engine cylinder by the fuel injector mechanism, and mixed with the oxygen in the turbulent oxygen plasma to undergo a combustion reaction, so that a uniform dispersion system of fuel and hydrogen is formed in the cylinder, and the combustion of hydrogen and fuel in the cylinder is more uniform, thereby promoting the complete combustion of fuel and oxygen, improving fuel efficiency, increasing power output, and reducing pollution emissions.
[0028] (3.1) Furthermore, a low-pressure mixing solution of hydrogen and fuel is adopted. The fuel is output under the low-pressure state of the fuel tank's own oil pump. The liquid-gas mixer, under the action of the high-pressure oil pump at its rear section, fully mixes the fuel with the hydrogen produced in real time by the electrolysis equipment. The mixed hydrogen and fuel are pressurized by the high-pressure oil pump and better mixed and atomized in the liquid-gas atomization mechanism. This method achieves a delicate mixing of hydrogen and fuel on the basis of a simple structure, which helps to mix more evenly with the engine intake in the future and carry out a combustion reaction, so as to achieve a more complete reaction of the fuel during combustion and release more energy, thereby improving the combustion efficiency and the thermal efficiency of the engine, improving the degree of energy utilization, and achieving the purpose of energy saving.
[0029] (3.2) Furthermore, a high-pressure mixing solution of hydrogen and fuel is adopted. Without changing the basic structure of the crude oil line, a high-pressure oil pump is configured on the oil line, and a gas supercharger is configured on the second connecting pipe, so that both the fuel and hydrogen enter the liquid-gas mixer in a high-pressure state to be fully mixed and enter the liquid-gas atomization mechanism at high pressure, making the dispersion system between the fuel and hydrogen more delicate, which is conducive to the subsequent further mixing and combustion reaction. At the same time, the high-pressure oil pump can independently adjust the fuel oil pressure, and the gas supercharger can independently adjust the hydrogen pressure, so that the hydrogen and fuel mixing ratio can be adjusted according to the engine operating conditions, and can adapt to special operating conditions such as engine starting, low-speed high torque, idling, and high load.
[0030] (4) Furthermore, the combustion work structure in the present invention is equipped with an electrolysis device equipped with a circulating water tank, a water flow sensor switch, an ion exchange resin, a PEM electrolyzer, and a gas-water separator. Based on a relatively small water volume, the pure water produced by electrolysis can be controlled in terms of temperature, flow rate, and purity, thereby making the prepared hydrogen and oxygen more stable, pure, efficient, and controllable, so that the real-time hydrogen and oxygen production can be adapted to the operating conditions of various engines with mixed oxygen and hydrogen, thereby achieving improved combustion efficiency, increased power, and reduced emissions. At the same time, the water vapor produced during electrolysis can be recycled into the circulating water tank, which not only ensures the purity of the prepared hydrogen and oxygen, but also realizes the temperature-controlled recycling of pure water.

[0048] First embodiment Combination Figure 1 , Figure 7 and Figure 8 As shown, a new type of engine combustion and working structure according to the first embodiment of the present application is shown. The combustion and working structure is configured in the engine. The configured engine has an engine intake pipe 11, a fuel injection system, an engine exhaust pipe 14 and an engine control unit ECU. Among them, the engine intake pipe 11 enters each cylinder in the engine through the intake manifold, the fuel injection system injects fuel into each cylinder in the engine, and ignites it through the ignition device in the cylinder, thereby realizing the conversion of fuel chemical energy into mechanical energy output, and the engine control unit ECU controls the intake, fuel injection, ignition and exhaust processes of the engine cylinder.
[0049] To achieve the technical purpose of the present application, the combustion work structure of the present embodiment includes an electrolysis device 20, a system control ECU 80, a plasma generator 51, a gas turbulence mechanism 52, a first connecting pipe 40 and a second connecting pipe 60. In detail, the electrolysis device 20 is used to electrolyze the stored pure water into hydrogen and oxygen using a power supply. The electrolysis device 20 is provided with an oxygen output port 201 and a hydrogen output port 202. The hydrogen generated by the electrolysis device 20 is output from the hydrogen output port 202, and the oxygen generated by the electrolysis device 20 is output from the oxygen output port 201. Among them, the plasma generator 51 is arranged in the engine intake pipe, and is used to generate plasma gas from the gas in the engine intake pipe 11. The gas turbulence mechanism 52 is arranged in the plasma generator 51 or in the rear section of the plasma generator 51. The first connecting pipe 40 connects the oxygen output port 201 to the engine intake pipe 11 in the front section of the plasma generator 51. The first connecting pipe 40 is provided with an oxygen negative pressure valve 43. Oxygen achieves pressure balance of the oxygen output port 201 at the engine intake pipe 11 at the front section of the plasma generator 51 through the oxygen negative pressure valve 43. The second connecting pipe 60 connects the hydrogen output port 202 to the engine intake pipe 11 at the rear section of the gas turbulence mechanism 52. A hydrogen negative pressure valve 63 is provided on the second connecting pipe 60. Hydrogen achieves pressure balance of the hydrogen output port 202 at the engine intake pipe 11 at the rear section of the gas turbulence mechanism 52 through the hydrogen negative pressure valve 63. The system control ECU 80 is connected to the electrolysis device 20 and the plasma generator 51 to control the pure water electrolysis process and the supply process of hydrogen and oxygen.
[0050] When the combustion working structure of the first embodiment is in operation, the system control ECU 80 controls the electrolysis device 20 to perform electrolysis to generate hydrogen and oxygen. Among them, the oxygen is output to the first connecting pipe 40 through the oxygen output port 201 of the electrolysis device 20, and then output to the engine intake pipe 11 through the first connecting pipe 40, and mixed with the intake air, thereby increasing the oxygen concentration of the intake air. As the engine control unit ECU controls the intake of the engine cylinder, the once mixed intake air will pass through the plasma generator 51, and under the action of the plasma generator 51, oxygen positive and negative ions are generated. Subsequently, the plasma-generated intake air flows into the gas turbulence mechanism 52. Under the action of the gas turbulence mechanism 52, the intake air continues to move along the extension direction of the pipeline, and also forms irregular fluctuations in the radial direction of the intake pipe, and enters the engine cylinder after mixing with the hydrogen input from the second connecting pipe 60. Since the intake air enters the turbulent flow, it can be fully mixed with the hydrogen. At the same time, the oxygen that exceeds the prepared amount is plasmatized, so that after the engine cylinder is ignited, the electric fire is instantly transmitted to the entire cylinder through the plasmatized oxygen, so that the hydrogen evenly mixed with the oxygen undergoes a full combustion reaction. At the same time, the plasmatized oxygen also further undergoes a combustion reaction with the fuel in the engine cylinder. Under the action of hydrogen with higher combustion efficiency, the flame temperature in the cylinder is higher, combined with the active release of plasmatized oxygen at high temperature, the fuel burns more completely, effectively reducing the carbon monoxide (CO) and nitrogen oxides (NO) produced in the fuel combustion range. x ) and particulate matter, etc. The exhaust oxygen is reduced, and the fuel used will also be reduced under the control of the engine control unit ECU, so that the engine fuel consumption is reduced, the efficiency is increased, and the emission is more environmentally friendly. It is worth noting that the only byproduct of hydrogen combustion is water, which will not pollute the atmosphere, help reduce greenhouse gas emissions, and have a positive significance for improving air quality. Oxygen combustion helps achieve oxygen-enriched combustion, reduces the production of unburned hydrocarbons, carbon monoxide and other harmful substances, effectively reduces the emission of pollutants such as nitrogen oxides and particulate matter, and makes engine exhaust emissions cleaner and more environmentally friendly, in line with the global goals of reducing energy consumption, reducing greenhouse gas emissions and improving air quality. The high temperature generated by hydrogen combustion helps soften and decompose carbon deposits, and its high permeability and fast combustion speed can penetrate the carbon deposit layer and remove carbon deposits during the combustion process. The water vapor generated by hydrogen combustion can also clean the engine combustion chamber, intake valve, exhaust valve and other parts, restore engine performance and efficiency, and the liquid-gas atomization mechanism 72 in the engine fuel pipe 12 reduces local over-rich combustion and reduces carbon deposit formation. The exhaust pipe is connected to the oil-gas separator 92 in the middle of the intake pipe to prevent the oil from entering the cylinder and burning to produce carbon deposits. By separating the oil and gas and returning the separated oil to the engine, the gas is treated by the plasma generator 51 and the gas turbulence mechanism 52 to combine with hydrogen to improve the combustion efficiency, thereby indirectly reducing the factors causing carbon deposits. These all help to reduce the formation and accumulation of carbon deposits inside the engine, reduce engine wear, extend the service life of the engine, reduce the frequency and cost of engine maintenance, and improve the overall reliability and durability of the engine.
[0051] It is worth noting that the engine combustion and working structure of the present application can effectively improve the power output. Compared with engines with the same power and torque, such as a 2.0-displacement fuel vehicle engine, the power output is 180 horsepower; however, when the new engine combustion and working structure of the present application is configured on a 1.5-displacement engine, the power output also reaches 180 horsepower, thereby reducing the engine displacement, reducing fuel consumption and pollution emissions under the condition of the same engine power output, and achieving energy saving and environmental protection effects.
[0052] It is worth noting that the engine combustion and working structure of the present application effectively improves the performance of low-grade fuel (low octane number). For example, the anti-knock performance of No. 92 gasoline is relatively weak, and it is suitable for vehicles with an engine compression ratio between 8.5-9.5; the anti-knock performance of No. 95 gasoline is moderate, and it is suitable for vehicles with an engine compression ratio of more than 9.5; the anti-knock performance of No. 98 gasoline is the strongest, and it is suitable for high-end and high-horsepower models, as well as vehicles with a compression ratio of more than 11.6. In terms of price, the price of No. 92 gasoline is relatively low; the price of No. 95 gasoline is moderate, and the price of No. 98 gasoline is relatively high, because of its high quality and difficulty in refining. In terms of environmental protection effect, the environmental protection performance of No. 92 gasoline is general; the environmental protection performance of No. 95 gasoline is good, and No. 98 gasoline is environmentally friendly, with low sulfur content, high combustion value, and smoother operation. The engine is equipped with the new engine combustion and working structure of the present application, and the characteristics of high unit mass calorific value of hydrogen, low ignition energy, wide ignition limit, fast flame propagation speed, and water as the emission, enable low-grade fuel to achieve a stable combustion process and high anti-knock performance. In the low temperature oxidation (LTO) stage, low-grade fuel can also reduce the heat release rate under the action of hydrogen. In the high temperature stage, low-grade fuel will increase the heat release rate, achieving a stable combustion process under different combustion conditions. Overall, low-grade fuel has the anti-knock, high compression ratio, environmental protection and efficient combustion effects of high-grade fuel on the basis of low fuel cost.
[0053] It is worth noting that the ion generator is used to generate plasma gas from the gas in the engine intake pipe 11, and the ion generator can realize various structures. Figure 2 As shown, the plasma generator 51 includes a first pipe body 511, an anode body 512 and a cathode body 513. The anode body 512 and the cathode body 513 are fixedly arranged inside the first pipe body 511. The anode body 512 is tubular, and a plurality of hole-shaped electrodes are arranged on the inner wall to receive electrons and complete the conduction of the circuit. The cathode body 513 is columnar, and a plurality of needle-shaped electrodes are arranged on the outer wall, which is the source of electron emission and is usually made of a material that is resistant to high temperatures and easy to emit electrons, such as tungsten wire. When the plasma generator 51 is running, a DC high voltage is applied between the anode body 512 and the cathode body 513, and the gas flows in from the inlet of the first pipe body 511. After passing through the numerous needle-shaped electrodes of the cathode body 513, the gas will form plasma, thereby forming an electrical path with the anode body 512, and the plasmatized gas flows out from the outlet of the first pipe body 511.
[0054] It is worth noting that the gas turbulence mechanism 52 is used to make the gas after plasmatization flow turbulently in the radial direction. The achievable structures are various, and the key is to make the gas form irregular fluctuations in the longitudinal direction on the basis of moving along the pipeline direction. To this end, micro-scale channels or tiny protrusion structures are constructed inside the pipeline. These microstructures can effectively disrupt the flow of gas and promote turbulence without significantly increasing the macro resistance. The size of the microchannel is comparable to the mean free path of the gas molecules, which can change the flow characteristics of the gas at the microscopic level and produce a turbulent effect, while the overall pressure loss is relatively small. Surface texturing: The inner wall of the pipeline is subjected to surface texturing to form a specific microscopic pattern. These textures can guide the gas to form orderly small-scale vortices, thereby generating turbulence. At the same time, due to the design optimization of the texture, the resistance to gas flow will not be greatly increased.
[0055] Specifically, in this embodiment, Figure 2 As shown, the gas turbulence mechanism 52 includes a second pipe body 521, and a turbulence structure 522 arranged inside the second pipe body 521. A plurality of through holes are arranged in the turbulence structure 522, and the inlet of each through hole does not overlap with the outlet of each through hole axially, so that the gas is deflected in the radial direction. The deflection directions between the through holes are different, and further collide with each other to form irregular turbulence. When the gas turbulence mechanism 52 is in operation, the gas enters from one end of the second pipe body 521, enters the expansion section of the second pipe body 521, and enters one end of the turbulence structure 522, and is output from the other end of the turbulence structure 522, and enters the contraction section of the second pipe body 521. Before entering the turbulence structure 522, the gas flows along the pipe direction, and after the gas flows out from the through hole, radial fluctuations are generated, and the gases in different through holes further collide with each other to form irregular turbulence.
[0056] It is understandable that the engine combustion and working structure of the present application uses electrolysis equipment to prepare hydrogen and oxygen in real time, thereby improving the safety of engine operation, achieving auxiliary fuel to improve combustion efficiency, reduce emissions and increase power. This requires the electrolysis equipment of the engine combustion and working structure to meet the conditions for stable, pure, efficient and controllable hydrogen and oxygen preparation.
[0057] For this reason, Figure 7 As shown, according to a new engine combustion and working structure of the first embodiment of the present application, the electrolysis device 20 includes a main water storage tank 31, a circulating water tank 21, a first water pump 33, a water flow sensing switch 24, an ion exchange resin 26, a PEM electrolyzer 27, an oxygen gas-water separator 28, a hydrogen gas-water separator 29, a three-way electronic valve 30 and a constant voltage and constant current power supply 32.
[0058] Among them, a constant temperature heater 25 is arranged inside the circulating water tank 21, and the constant temperature heater 25 is electrically connected to the system control ECU80 to control the water temperature in the circulating water tank 21. The constant temperature heater 25 is used to heat and control the constant temperature of the electrolyzed water and provide a temperature detection signal. The water outlet of the circulating water tank 21 is connected to one end of the water flow sensor switch 24 through the first water pump 33, and the water flow sensor switch 24 is electrically connected to the system control ECU80 to provide a water flow working signal. The other end of the water flow sensor switch 24 is connected to the inlet of the ion exchange resin 26. The ion exchange resin 26 is used to further remove impurity ions in the water so that the electrolysis equipment can realize water circulation. The outlet of the ion exchange resin 26 is connected to the water inlet of the PEM electrolyzer 27. The constant voltage and constant current power supply 32 is connected to the PEM electrolyzer 27 for power supply, and the system control ECU80 controls the connection to the constant voltage and constant current power supply 32. The constant voltage and constant current power supply 32 is preferably configured to be powered by the battery of the car. The PEM electrolyzer 27 electrolyzes pure water under the action of power supply to generate hydrogen and oxygen. Among them, the hydrogen port of the PEM electrolyzer 27 is connected to the hydrogen gas-water separator 29, the exhaust port of the hydrogen gas-water separator 29 serves as the hydrogen output port 202 of the electrolysis device and is connected to the second connecting pipe 60, and the water outlet of the hydrogen gas-water separator 29 is connected to the circulating water tank 21. The oxygen port of the PEM electrolyzer 27 is connected to the oxygen gas-water separator 28, the exhaust port of the oxygen gas-water separator 28 serves as the oxygen output port 201 of the electrolysis device and is connected to the first connecting pipe 40. The water outlet of the oxygen gas-water separator 28 is connected to the circulating water tank 21 through the three-way electronic valve 30. The other water outlet of the three-way electronic valve 30 is connected to the drain pipe. The three-way electronic valve 30 is controlled and connected to the system control ECU 80, so as to control the three-way electronic valve 30 to discharge waste water when the circulating water tank 21 is full of water or the number of cycles reaches the set value.
[0059] It can be seen that the electrolysis equipment of the present application is provided with a circulating water tank 21, which makes the pure water of electrolysis controllable in temperature, flow rate and purity on the basis of less water capacity, so that the pure water electrolysis hydrogen production is stable under the set conditions, and the efficiency of electrolysis is higher, so that the real-time hydrogen and oxygen preparation is adapted to the operating conditions of various engines mixed with oxygen and hydrogen, so as to achieve improved combustion efficiency, increased power and reduced emissions. At the same time, the water vapor generated in the electrolysis can be recycled into the circulating water tank 21, which not only ensures the purity of the prepared hydrogen and oxygen, but also realizes the temperature-controlled pure water recycling.
[0060] Further, the electrolysis equipment of this embodiment is equipped with a main water storage tank 31, and the main water storage tank 31 is connected to the circulating water tank 21 through the second water pump 34. A water level sensor 22 and a TDS water quality detection sensor 23 are also provided in the circulating water tank 21. The system control ECU 80 is electrically connected to the water level sensor 22, the TDS water quality detection sensor 23, and the second water pump 34 in the circulating water tank 21. When the water level sensor 22 in the circulating water tank 21 is lower than the preset water level, the system control ECU 80 controls the second water pump 34 to operate, so that the main water storage tank 31 adds water to the circulating water tank 21. When the TDS water quality detection sensor 23 detects that the water quality is lower than the preset condition, the system control ECU 80 controls the circulating water tank 21 to drain water, and at the same time controls the main water storage tank 31 to add water to the circulating water tank 21. A water level sensor 22 is provided inside the main water tank 31. The system control ECU 80 is electrically connected to the water level sensor 22 in the main water tank 31 to obtain the water volume of the main water tank 31 and display it on the multi-function display screen 35 to prompt the user to add purified water in time.
[0061] It can be seen that the electrolysis equipment of the present application adopts a circulating water tank 21, a constant temperature heater 25, an ion exchange resin 26, a PEM electrolyzer 27, a gas-water separator, etc. to achieve controllable, stable and efficient hydrogen and oxygen production, and uses the main water storage tank 31 for auxiliary water addition, so that the electrolysis equipment can better cooperate with the engine internal combustion conditions of mixed hydrogen and oxygen.
[0062] Further, in this embodiment, the first connecting pipe 40 is provided with an oxygen pressure sensor 41 and an oxygen flow sensor 42, and the second connecting pipe 60 is provided with a hydrogen pressure sensor 61 and a hydrogen flow sensor 62. The system control ECU 80 is electrically connected to the oxygen pressure sensor 42, the oxygen flow sensor 42, the hydrogen pressure sensor 61 and the hydrogen flow sensor 62, respectively, so as to obtain the oxygen flow and pressure in the first connecting pipe 40, and obtain the hydrogen flow and pressure in the second connecting pipe 60. Under the working condition of high hydrogen and oxygen consumption, the system control ECU 80 detects the decrease of oxygen flow and pressure and the decrease of hydrogen flow and pressure, and then controls the temperature of the thermostatic heater 25 to increase, the flow rate of the first water pump 33 to increase, and the power of the constant temperature and constant pressure power supply to increase, so that the hydrogen and oxygen flow and pressure meet the needs. Similarly, the system control ECU 80 can also reduce the operating efficiency of the electrolysis equipment when the hydrogen and oxygen flow and pressure are high.
[0063] Second embodiment Combination Figure 3 , Figure 7 and Figure 8 As shown, a new type of engine combustion and working structure according to the second embodiment of the present application is provided. The combustion and working structure is configured in an engine. The configured engine has an engine intake pipe 11, a fuel injection system, an engine exhaust pipe 14 and an engine control unit ECU.
[0064] To achieve the technical purpose of the present application, the combustion work structure of the present embodiment includes an electrolysis device 20, a system control ECU 80, a plasma generator 51, a gas turbulence mechanism 52, a first connecting pipe 40, a second connecting pipe 60, a liquid-gas mixer 71 and a liquid-gas atomization mechanism 72. In detail, the electrolysis device 20 is provided with an oxygen output port 201 and a hydrogen output port 202, the hydrogen generated by the electrolysis device 20 is output from the hydrogen output port 202, and the oxygen generated by the electrolysis device 20 is output from the oxygen output port 201. The plasma generator 51 is arranged in the engine intake pipe, and the first connecting pipe 40 connects the oxygen output port 201 with the engine intake pipe 11 at the front section of the plasma generator 51. An oxygen negative pressure valve 43 is arranged on the first connecting pipe 40 to balance the pressure of the oxygen output port 201 and the engine intake pipe 11. The first connecting pipe 40 is also provided with an oxygen pressure sensor 41 and an oxygen flow sensor 42 to obtain the pressure parameters and flow parameters of oxygen.
[0065] The difference from the first embodiment is that the second connecting pipe 60 connects the hydrogen output port 202 to the fuel injection system. Specifically, the hydrogen output port 202 is connected to the hydrogen pressure sensor 61 so that the system control ECU 80 obtains the pressure parameters of the hydrogen. The hydrogen pressure sensor 61 is connected to the hydrogen flow sensor 62 so that the system control ECU 80 obtains the flow parameters of the hydrogen. The hydrogen flow sensor 62 is connected to the air inlet of the liquid-gas mixer 71 through the one-way valve 64. On the other hand, the fuel injection system includes a fuel tank, an engine fuel pipe 12, a high-pressure oil pump 73 and a fuel injection nozzle mechanism 13. The fuel tank is connected to the liquid inlet of the liquid-gas mixer 71 through the one-way valve 64, and the outlet of the liquid-gas mixer 71 is connected to the inlet of the high-pressure oil pump 73, so that the mixed fuel and hydrogen are sucked by the pressure of the high-pressure oil pump 73. The outlet of the high-pressure oil pump 73 is connected to the inlet of the liquid-gas atomization mechanism 72, so that the hydrogen and fuel are atomized in the liquid-gas atomization mechanism 72. The outlet of the liquid-gas atomizing mechanism 72 is connected to the fuel injection nozzle mechanism 13, so that the atomized hydrogen and fuel are injected into the engine cylinder in the fuel injection nozzle mechanism 13 for combustion.
[0066] When the combustion work structure of the second embodiment is in operation, on the one hand, the oxygen prepared by the electrolysis device 20 is mixed with the intake air, and oxygen positive and negative ions are generated under the action of the plasma generator 51, and then turbulence is formed under the action of the gas turbulence mechanism 52, and enters and fills the engine cylinder. On the other hand, hydrogen enters the liquid-gas mixer 71 through the second connecting pipe 60, and is mixed with the fuel that also enters the liquid-gas mixer 71, and enters the liquid-gas atomization mechanism 72 under the action of the high-pressure oil pump 73. The mixed fuel and hydrogen form a mist and are sprayed into the engine cylinder at the fuel injector. The atomized mixed fuel and hydrogen fill the engine cylinder and are dispersed in the plasma-formed intake air in the engine cylinder that is evenly distributed due to turbulence. When the engine cylinder is ignited, the electric fire is instantly transmitted to the entire cylinder through the plasma-formed oxygen, so that the hydrogen and oxygen undergo a rapid and uniform combustion reaction, and the increased heat further promotes the ignition of the atomized fuel dispersed near the hydrogen, thereby combining with a large amount of fuel gas for full combustion and converting into mechanical energy to do work.
[0067] It can be seen that in the first embodiment, plasma turbulent oxygen can be generated through the plasma generator 51 and the gas turbulence mechanism 52, and fully mixed with hydrogen, so that the hydrogen of the electrolysis device is fully burned and the fuel is burned efficiently and powerfully. In the second embodiment, further, through the liquid-gas mixer 71 and the liquid-gas atomization mechanism 72, the sprayed fuel can be fully dispersed into the engine cylinder by mixing hydrogen and fuel, and the combustion reaction of hydrogen and plasma intake air is fully mixed to promote the combustion reaction of fuel and oxygen, so as to achieve high combustion efficiency, high power, low fuel consumption and low emissions.
[0068] It is worth noting that, in this embodiment, the oil pump of the engine fuel pipe 12 is configured as a high-pressure oil pump 73, and a liquid-gas mixer 71 is arranged on the oil path between the high-pressure oil pump 73 and the fuel tank, and a one-way valve 64 is arranged between the fuel tank and the liquid-gas mixer 71 to prevent hydrogen or fuel from flowing back to the fuel tank. The air inlet of the liquid-gas mixer 71 is connected to the second connecting pipe 60 through the one-way valve 64, so as to introduce hydrogen and prevent hydrogen from flowing back to the second connecting pipe 60. Under the action of the high-pressure oil pump 73, hydrogen and fuel are mixed with each other and pumped into the liquid-gas atomization mechanism 72. In this embodiment, the fuel is output under the low-pressure state of the fuel tank's own oil pump, and the liquid-gas mixer 71, under the action of the high-pressure oil pump 73 at its rear section, fully mixes the fuel with the hydrogen produced in real time by the electrolysis equipment, and the mixed hydrogen and fuel are pressurized by the high-pressure oil pump 73, and are better mixed and atomized in the liquid-gas atomization mechanism 72. This method achieves a fine mixing of hydrogen and fuel based on a simple structure, which helps to mix them more evenly with the engine intake air and carry out a combustion reaction, so as to achieve a more complete reaction of the fuel during combustion and release more energy, thereby improving combustion efficiency and the thermal efficiency of the engine, enhancing energy utilization and achieving the purpose of energy saving.
[0069] It can be understood that in the new engine combustion and working structure of the second embodiment, similarly, Figure 7 As shown, the electrolysis device 20 includes a main water storage tank 31, a circulating water tank 21, a first water pump 33, a water flow sensor switch 24, an ion exchange resin 26, a PEM electrolyzer 27, an oxygen gas-water separator 28, a hydrogen gas-water separator 29, a three-way electronic valve 30 and a constant voltage and constant current power supply 32. A constant temperature heater 25 is arranged in the circulating water tank 21, and the electrolysis equipment is provided with an ion exchange resin 26, an oxygen gas-water separator 28, and a hydrogen gas-water separator 29, so that the pure water of the electrolysis can be controlled in temperature, flow rate, and purity, so that the pure water electrolysis hydrogen production is stable under the set conditions, and the efficiency of the electrolysis is higher, so that the real-time hydrogen and oxygen preparation is adapted to the operating conditions of various engines mixed with oxygen and hydrogen, so as to achieve improved combustion efficiency, increased power and reduced emissions. At the same time, the water vapor generated in the electrolysis can be recycled into the circulating water tank 21, which not only ensures the purity of the prepared hydrogen and oxygen, but also realizes the temperature-controlled pure water recycling. At the same time, the main water tank 31 is used for auxiliary water addition, so that the electrolysis equipment can better cooperate with the internal combustion working conditions of the engine with mixed hydrogen and mixed oxygen.
[0070] It is worth noting that the liquid-gas mixer 71 is used to mix fuel and hydrogen, and its achievable structure is diverse. Figure 5 As shown, in this embodiment, specifically, the liquid-gas mixer 71 includes a third pipe body 711. One end of the third pipe body 711 is configured as a liquid inlet, the same end of the third pipe body 711 and located on one side is configured as an air inlet, and the other end of the third pipe body 711 is configured as an outlet. The liquid-gas mixer 71 also includes a third convergent pipe 712 disposed inside the third pipe body 711 and connected to the liquid inlet, an air cavity 713 disposed outside the convergent pipe and connected to the air inlet, a narrow mixing pipe 714 connected to the air cavity 713 and coaxial with the third convergent pipe 712, and a third expansion pipe 715 connected to the end of the narrow mixing pipe 714. When the liquid-gas mixer 71 is in operation, under the action of pressure, the fuel enters the third convergent tube 712 from the liquid inlet, and then enters the mixing narrow tube 714 in a pressurized manner; at the same time, hydrogen enters the air cavity 713 from the air inlet, and is sucked into the mixing narrow tube 714 with its own air pressure and the negative pressure generated by the fuel entering the mixing narrow tube 714, and finally the mixed fuel and hydrogen flow out from the third expansion tube 715. It is worth noting that since the entry into the mixing narrow tube 714 is achieved according to the hydrogen pressure and the fuel pressure, the hydrogen and fuel mixed in the mixing narrow tube 714 can achieve stability on the fluid flow layer, and can be controlled with the adjustment of the hydrogen pressure and the fuel pressure, thereby avoiding the problem of uneven ratio of hydrogen and fuel between multiple injections due to uneven mixing.
[0071] It is worth noting that the liquid-gas atomizing mechanism 72 is used to atomize the mixed fuel and hydrogen, and its achievable structure is diverse. Figure 6 As shown, in this embodiment, specifically, the liquid-gas atomization mechanism 72 includes a fourth pipeline body 721, a fourth contraction tube 722 arranged at one end of the fourth pipeline body 721, an atomization chamber 723 arranged at the end of the fourth contraction tube 722, a fourth expansion tube 725 arranged at the other end of the atomization chamber 723, and a spoiler structure 724 arranged inside the atomization chamber 723. The spoiler structure 724 is in the shape of a fan blade, and has a terminal near one end of the fourth contraction tube 722. When the mixed hydrogen and fuel enter the fourth convergent tube, the pressure can be further increased and accelerated. When entering the inside of the atomization chamber 723, the mixed hydrogen and fuel are dispersed to various parts of the atomization chamber 723 under the action of the terminal, and enter the spoiler structure 724 equipped with a fan blade, and the fuel, hydrogen and spoiler structure 724 collide with each other to form fine particles mixed in the hydrogen, and flow out from the fourth expansion tube 725. The fourth expansion tube 725 allows the liquid pressure to rise, and can maintain a certain outlet speed, which helps to maintain the atomization effect. When the mixed hydrogen and fuel atomized by the liquid-gas atomization mechanism 72 enters the engine cylinder, the hydrogen and the mist fuel can evenly fill the cylinder, thereby making the combustion reaction more complete. Optionally, the spoiler structure 724 can be selected in a variety of ways, the key is to form a collision with the hydrogen and the fuel to achieve the atomization of the fuel. In other embodiments, the spoiler structure 724 can also be a staggered baffle structure, or a porous structure with different directions.
[0072] It is worth adding that Figure 6 As shown, the liquid-gas atomization mechanism 72 of this embodiment further includes an ultrasonic vibration generator 726. The ultrasonic vibration generator 726 causes the liquid in the atomization chamber 723 or near the outlet to generate high-frequency vibrations under the action of the ultrasonic vibration generator 726, making it easier for the liquid to overcome surface tension and break into tiny droplets, which helps to further refine the droplets and significantly improve the atomization effect.
[0073] Third embodiment like Figure 4 As shown, a new type of engine combustion and working structure according to the third embodiment of the present application is shown. The combustion and working structure is configured in the engine. The configured engine has an engine intake pipe 11, a fuel injection system, an engine exhaust pipe 14 and an engine control unit ECU. The combustion and working structure of this embodiment includes an electrolysis device 20, a system control ECU 80, a plasma generator 51, a gas turbulence mechanism 52, a first connecting pipe 40, a second connecting pipe 60, a liquid-gas mixer 71 and a liquid-gas atomization mechanism 72.
[0074] The difference from the second embodiment is that a high-pressure oil pump 73 is provided on the engine fuel pipe 12, and a gas booster 74 is provided on the second connecting pipe 60. The high-pressure oil pump 73 is provided at the front section of the one-way valve 64 where the engine fuel pipe 12 and the liquid-gas mixer 71 are connected, and the gas booster 74 is provided at the front section of the one-way valve 64 where the second connecting pipe 60 and the liquid-gas mixer 71 are connected. During operation, the gas booster 74 provides high-pressure hydrogen with adjustable pressure, the high-pressure oil pump 73 provides high-pressure fuel with adjustable pressure, and the liquid-gas mixer 71 mixes the high-pressure hydrogen and the high-pressure fuel to form a mixture with a stable ratio of hydrogen and fuel in the flow layer.
[0075] It can be seen from this that without changing the basic structure of the crude oil circuit, a high-pressure oil pump 73 is arranged on the oil circuit, and a gas supercharger 74 is arranged on the second connecting pipe 60, so that the fuel and hydrogen enter the liquid-gas mixer 71 in a high-pressure state to be fully mixed and enter the liquid-gas atomization mechanism 72 at high pressure, so that the dispersion system between the fuel and hydrogen is more delicate, which is conducive to the subsequent further mixing and combustion reaction. At the same time, the high-pressure oil pump 73 can independently adjust the fuel oil pressure, and the gas supercharger 74 can independently adjust the hydrogen pressure, so that the mixing ratio of hydrogen and fuel can be adjusted according to the engine working conditions, and can adapt to special working conditions such as engine starting, low speed and high torque, idling, and high load.
[0076] It is worth adding that Fig. 9 As shown, in the new engine combustion and working structure according to each embodiment of the present invention, the engine exhaust pipe 14 is provided with an oil-water separator, the gas outlet of the oil-water separator is connected to the engine intake pipe 11 in front of the plasma generator 51, and the liquid outlet of the oil-water separator is connected to the inside of the engine. During operation, under special working conditions, such as the start-up state, the combustion of fuel and hydrogen will not be sufficient. At this time, the exhaust gas in the engine exhaust pipe 14 can be separated by the oil-water separator and introduced into the engine intake pipe 11, and the recovered hydrogen and oxygen can be burned again, and the recovered fuel can be used as engine oil and flow into the engine cylinder.
[0077] It is worth adding that the new engine combustion working structure according to each embodiment of the present invention also includes an ignition enhancement angle corrector 91. Specifically, the ignition enhancement angle corrector 91 is installed with the engine, and the ignition enhancement angle corrector 91 is connected to the system control ECU 80. The system control ECU 80 can correct the timing of ignition in the engine cylinder according to parameters such as the flow rate and pressure of oxygen, the flow rate and pressure of hydrogen, the power of the plasma generator 51, and the mixing ratio of fuel and hydrogen, so that the ignition is triggered when the plasma intake, hydrogen, and fuel are evenly dispersed in the engine cylinder, thereby achieving improved combustion efficiency and reduced combustion emissions.
[0078] It is worth adding that the membrane electrode, bipolar plate, gas diffusion layer, end plate and other components of the PEM electrolyzer 27 can be installed inside the engine and integrated with the engine. By setting corresponding pipelines and sensor installation positions and water pumps on the engine body, the heat from the engine operation is used to heat the electrolyzed water. The system control ECU808 program is integrated with the engine control unit ECU15, and the multi-function LCD display program is integrated with the vehicle's central control screen and instrument, which is displayed on the central control screen and instrument. This can save space and cost, improve work efficiency and reduce maintenance costs.
[0079] It is worth adding that Figure 8 As shown, many sensors in the system, such as the water level sensor 22, the TDS water quality detection sensor 23, the oxygen pressure sensor 41, the hydrogen pressure sensor 61, etc., monitor the parameters of each key link in real time and feed back the signal to the system control ECU. The system control ECU 80 accurately regulates the entire system based on these data, including the control of the first water pump 33, the second water pump 34, the electrolysis equipment, the three-way electronic valve 30 and other components, to ensure that all components of the system always work in the best state and maintain the stable operation of the system. For example, the water level sensor 22 monitors the water level of the main water storage tank 31 and the circulating water tank 21 in real time. When the water level of the circulating water tank 21 is too low, the system control ECU 80 can start the second water pump 34 to replenish water in time to avoid electrolysis equipment failure or combustion system abnormality due to lack of water. When the main water storage tank 31 is detected to be short of water, the multi-function LCD screen displays the low water level and reminds you to add water. When there is no water at all, the system will stop working.
[0080] It is worth adding that pure water is used as an electrolyte to produce hydrogen and oxygen in real time through a PEM (proton exchange membrane) electrolyzer. Pure water allows the PEM electrolyzer 27 to operate at a higher current density, generating more hydrogen and oxygen in a shorter time, thereby improving the overall energy conversion efficiency. It can also produce high-purity hydrogen and oxygen, avoiding the alkaline liquid pollution and corrosion problems of alkaline electrolyzers, helping to protect the materials inside the electrolyzer, extending the service life of the equipment, and reducing the impact on the environment. In order to effectively reduce the conductivity of the hydrogen and oxygen production components of the electrolyzer, improve the electrolysis efficiency, reduce energy consumption, and enhance the economy and sustainability of the entire hydrogen production system, the PEM (proton exchange membrane) electrolyzer components use diaphragm materials with low resistivity and good mechanical strength, and optimize the thickness and pore size design of the diaphragm; optimize the electrode design. The electrode is the main site of the water electrolysis reaction, and its design has an important influence on the electrolysis efficiency and energy consumption. The use of precious metals or metal oxides as electrode materials and the optimization of electrode structures, such as flat, mesh and porous types, are all helpful to improve the electrolysis efficiency and reduce the conductivity. NiS can be plated on the cathode to reduce the overvoltage of hydrogen, thereby reducing the conductivity. At the same time, maintaining the rapid circulation of the electrolyte to bring out the bubbles as soon as possible and reduce the gas content of the electrolyte, also helps to reduce the conductivity.
