Description

Technical Field

[0001] The present invention relates to the technical field of internal combustion engines, and more particularly to a negative ion combustion improver for internal combustion engines. Background Art

[0002] With the development of technology and the progress of living standards, combustion equipment has become a tool for generating power in modern technology. However, the fuel oil that provides power for combustion equipment comes from petroleum raw materials. Petroleum is not a natural resource that is inexhaustible and will eventually be depleted. At the same time, burning fuel oil will also produce waste gas, causing air pollution. With the increasing popularity of environmental protection concepts and the gradual shortage of energy on the earth, fuel oil is still the main power fuel for current combustion equipment. However, the formation of petroleum does not happen overnight. Therefore, in order to extend the service life of petroleum and reduce the air pollution problem caused by using fuel oil, increasing the combustion efficiency is the most direct method.

[0003] There are many existing methods for improving combustion and saving fuel in internal combustion engines, and the theories on which they are based are also different. For example, the once-popular ozone combustion promotion theory can significantly save fuel consumption and improve the power of internal combustion engines. However, due to the strong oxidizing property of ozone, it will cause the accelerated oxidation of metals in the vehicle, and the components such as the internal combustion engine cylinder block will be damaged after long-term use, resulting in more losses than gains, and it has gradually been phased out.

[0004] In recent years, some people have introduced negative ions into the field of internal combustion engines. Using negative ions to promote combustion is completely different from using ozone to promote combustion. Ozone is a bactericidal disinfectant, while negative ions are a kind of cleaner that can clean the air and are the main element of air purifiers. However, in terms of the application of negative ions in energy conservation and emission reduction of internal combustion engines, most of the existing vehicle-mounted negative ion generators only have one output head, and the negative ion concentration is very low. They are mainly used to purify the air in the carriage, thereby affecting the cylinder mixture airflow, and the effect is not obvious. Even the products recognized by the official are only a negative ion air purifier, and there is still a large gap from the full play of the effectiveness of negative ions in the field of internal combustion engines, especially in the field of motor vehicle internal combustion engines. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a negative ion combustion improver for internal combustion engines to solve the technical problem of the lack of high-efficiency negative ion air purifiers in the field of internal combustion engines in the prior art.

[0006] To achieve the above object, the present invention provides a negative ion combustion aid for an internal combustion engine, which is installed between an air filter and a carburetor, 5-15 cm away from the throttle valve. It includes a plurality of negative ion generators. The negative ion generator includes a tube body and an airtight sleeve arranged in the tube body. One end of the tube body is an air inlet, and the opposite end is an air outlet. A plurality of negative ion generating units are arranged in sequence along the axial direction of the airtight sleeve in the airtight sleeve. A conical hole is arranged in the negative ion generating unit. The negative ion generating unit makes the air continuously expand and contract through the conical hole to generate small molecule gas;

[0007] The far-infrared negative ion material in the negative ion generating unit includes tourmaline, germanium ore, gui yang stone and rare earth element cerium. Tourmaline, germanium ore, gui yang stone and rare earth element cerium are mixed in a weight ratio of (6-8):(1-2):1:(0.1-0.5) in sequence.

[0008] Optionally, the negative ion generating unit has a columnar structure, and the conical hole inside it extends along the axial direction of the negative ion generating unit. The height of the negative ion generating unit is the same as the length of the conical hole.

[0009] Optionally, the conical hole includes a first end and a second end. The first end faces the air inlet, and the second end faces the air outlet.

[0010] Optionally, adjacent negative ion generating units are closely arranged.

[0011] Optionally, an air inlet connecting pipe seat is arranged at the air inlet. An air inlet channel is arranged in the air inlet connecting pipe seat. The air inlet channel is communicated with the conical hole, and the air inlet channel is also communicated with the channel formed between the outer wall of the negative ion generating unit and the inner wall of the airtight pipe.

[0012] Optionally, the air inlet channel is columnar.

[0013] Optionally, an air outlet connecting pipe seat is arranged at the air outlet. An air outlet channel is arranged in the air outlet connecting pipe seat. The air outlet channel is communicated with the conical hole; the air outlet channel is conical.

[0014] Optionally, a spiral groove is arranged on the outer wall of the negative ion generating unit.

[0015] Optionally, it further includes a fixer. The fixer has an annular structure or an arc-shaped structure. A plurality of fixing parts are arranged on the fixer. The number of the fixing parts is the same as the number of the negative ion generators. A clamping part is arranged on the outer wall of the negative ion generator, and the clamping part is adapted to the fixing part.

[0016] Optionally, the fixing part is a U-shaped clamping groove.

[0017] The negative ion combustion promoter for internal combustion engines provided by the present invention has the following technical effects:

[0018] This kind of negative ion combustion promoter is used for internal combustion engines and is installed between the air filter and the carburetor, 5 - 15 cm away from the throttle valve. It includes several negative ion generators, which cause the air to undergo an ionization reaction before entering the carburetor, generating active oxygen free radicals O2- and hydrogen H2. The oxidation performance of O2- is many times stronger than that of O2. After entering the carburetor and combining with fuel molecules, it can break the van der Waals force between fuel molecules, form a long-chain ordered arrangement, break the molecular chain of hydrocarbons (C m H n ) from "long chain" to "short chain", turn large molecules into small molecules, increase the average distance between molecules, reduce the fuel concentration, greatly improve the fluidity and atomization performance, reduce the activation energy required for the reaction, increase the fuel coefficient, reduce the thermal activation energy required for the reaction, accelerate the reaction rate, play a role in activating the fuel, make the combustion more complete, reduce the content of harmful gases in the exhaust gas, increase the calorific value of the fuel, and achieve the purpose of fuel saving and emission reduction.

[0019] In addition, after the air of the present invention enters the pipe body from the air inlet, it sequentially passes through each negative ion generating unit in the airtight sleeve. When the air flow passes through the conical hole, due to the change in cross-sectional area, multiple expansion and contraction processes occur, increasing the collision frequency between gas molecules, promoting the dissociation of large molecular clusters into small molecule states, and then supplying them for use in combustion equipment during combustion, thereby achieving the effect of improving combustion efficiency and reducing exhaust gas emissions.

[0033] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0034] In the prior art, the internal combustion engine combustion promotion and fuel saving technology has gone through various theoretical practices. Ozone combustion promotion was once eliminated due to strong oxidizing properties causing metal corrosion. Although the application of negative ions has the effect of cleaning the air, traditional vehicle-mounted negative ion generators are only equipped with a single output head, and the negative ion concentration is not sufficient to effectively improve the combustion efficiency. Especially during the fuel combustion process, low-concentration negative ions cannot fully decompose the large molecular carbon chain structure, resulting in incomplete combustion and pollutant residues.

[0035] Note: The 7-digit tag

[0029] is preserved as it is as per the instruction. If there are any specific requirements or corrections regarding this tag in the actual context, it may need to be adjusted accordingly. Also, please double-check if there are any specific rules or preferences for handling such tags in your actual work environment.To solve the above problems, it is first necessary to overcome the defect of insufficient output capacity of traditional negative ion generators. By analyzing the aerodynamic characteristics, it is found that the motion state of gas molecules in a confined space directly affects the energy transfer efficiency. Based on this, it is considered to set up multiple action units in a single generator and use the principle of fluid mechanics to promote continuous expansion and contraction of the gas. At the same time, aiming at the problem of single function of negative ion materials, the synergistic effect of different mineral materials is studied, and the proportion relationship of composite materials is explored to release high-concentration negative ions under mechanical stress and air flow disturbance.

[0036] Therefore, the present invention proposes a negative ion combustion promoter for internal combustion engines, as Figures 1-9 shown, which includes a plurality of negative ion generators 1. Each generator has a tube body 11 and an internal airtight sleeve 12. An air inlet and an air outlet are respectively arranged at both ends of the tube body 11. A plurality of negative ion generating units 13 are arranged axially in the airtight sleeve 12. The adjacent negative ion generating units 13 are closely arranged, and a conical hole 131 structure is formed inside each unit to guide the air to generate continuous volume change through the conical hole 131. The negative ion generating unit 13 adopts a composite mineral material of tourmaline, germanium ore and gui yang stone, and the weight ratio of the three is controlled within a specific range.

[0037] The negative ion generator 1 is a device that can generate air negative ions through physical or chemical actions, and can be realized by means of high-voltage discharge or triboelectrification of mineral materials. The airtight sleeve 12 and the inner wall of the tube body 11 form a cylindrical structure with a sealed cavity, which can be made of metal or high-temperature resistant plastic to isolate external environmental interference. The cross-sectional size of the conical hole 131 is a through-hole structure that changes along the air flow direction, and can be specifically prepared by mechanical processing or die forming methods, and its geometric shape changes the gas flow velocity and pressure distribution.

[0038] The far-infrared negative ion material is a composite mineral that releases infrared radiation in a specific band and is accompanied by the release of negative ions. Tourmaline provides a spontaneous polarization electric field, germanium ore enhances the infrared radiation intensity, and gui yang stone optimizes the structural stability of the material. The three are mixed in proportion and then formed into a porous ceramic body through a sintering process.

[0039] Specifically, tourmaline, germanium ore, gui yang stone and rare earth element cerium are mixed in a weight ratio of 6:1:1:0.3, 7:2:1:0.2, 8:2:1:0.3 or 8:1:1:0.3 in sequence.

[0040] Specifically, after air enters the pipe body 11 from the air inlet, it successively passes through each negative ion generating unit 13 within the airtight sleeve 12. When the air flow passes through the tapered hole 131, multiple expansion and contraction processes occur due to the change in cross-sectional area, increasing the collision frequency between gas molecules and prompting the dissociation of large molecular clusters into small molecule states. The composite mineral material continuously releases negative ions under the action of air flow impact and mechanical vibration, and the negative ions attach to the surface of small molecule gases to form charged particle clusters. The processed gas is transported to the combustion chamber through the air outlet, and the charged particle clusters accelerate the breakage of fuel molecular chains in a high-temperature environment, shortening the combustion reaction time. The multi-stage negative ion generating units 13 are arranged axially to form a stepped treatment channel, ensuring that the gas fully contacts the active material during the flow process.

[0041] The negative ion combustor of the present invention is used for an internal combustion engine and is installed between the air filter and the carburetor, 5 - 15 cm away from the throttle valve. It includes several negative ion generators 1, which ionize the air before it enters the carburetor to produce active oxygen free radicals O2- and hydrogen H2. The oxidation performance of O2- is many times stronger than that of O2. After entering the carburetor and combining with fuel molecules, it can break the van der Waals force between fuel molecules, form a long-chain ordered arrangement, break the molecular chains of hydrocarbons (C m H n ) in the fuel from "long chains" to "short chains", turn large molecules into small molecules, increase the average distance between molecules, reduce the fuel concentration, greatly improve the fluidity and atomization performance, reduce the activation energy required for the reaction, increase the fuel coefficient, reduce the thermal activation energy required for the reaction, accelerate the reaction speed, play a role in activating the fuel, make the combustion more complete, reduce the content of harmful gases in the exhaust gas, increase the calorific value of the fuel, and achieve the purposes of fuel saving and emission reduction.

[0042] It should be noted that the tapered hole 131 of the present invention is the variable diameter mechanism. The variable diameter structure (such as a Venturi tube, a converging-diverging duct) enhances the negative ion release efficiency by changing the air flow velocity and pressure. The specific mechanisms include:

[0043] (a) Turbulence enhancement

[0044] - When the air flow passes through the variable diameter duct, the change in flow velocity (Bernoulli effect) forms turbulence, increasing the friction between air molecules and the surface of the far-infrared negative ion material.

[0045] - Triboelectrification (triboelectric effect) further promotes the charge separation of the far-infrared negative ion material, increasing the negative ion release amount.

[0046] (b) Pressure fluctuation promotes polarization

[0047] - The pressure of the gas changes suddenly at the variable diameter (such as the pressure decreases in the contraction section and recovers in the expansion section), causing the far-infrared negative ion crystal to be subjected to mechanical stress and enhancing the piezoelectric effect.

[0048] (c) Extend the air contact time

[0049] - The multi-stage variable diameter makes the air flow path more complex, extends the contact time between air and the far-infrared anion material, and increases the anion concentration.

[0050] Compared with the prior art, the traditional single-stage anion generator 1 can only achieve local gas treatment, while the axially arranged multi-stage units form a continuous action area, and the anion generation amount per unit volume increases significantly. The conical hole 131 structure replaces the traditional equal cross-section flow channel, and uses the gas compression and expansion effect to enhance the molecular activation efficiency. The composite mineral material breaks through the performance bottleneck of a single material through composition optimization and achieves a balance between mechanical stability and anion release efficiency.

[0051] Through the above technical solutions, the present invention realizes the effective dissociation of gas molecular clusters and the stable output of high-concentration anions, promotes the uniform mixing of fuel and air, and shortens the ignition delay period. Small molecule gases are more likely to combine with oxygen molecules, reducing the emissions of soot and nitrogen oxides generated by incomplete combustion.

[0052] The present invention further proposes that the anion generating unit 13 has a columnar structure, and the conical hole 131 inside it extends along the axis of the anion generating unit 13, and the height of the anion generating unit 13 is the same as the length of the conical hole 131.

[0053] The columnar structure refers to a three-dimensional geometric body with axial symmetry, and specifically can be realized by using a cylindrical or prismatic structure. This structure is conducive to the regular arrangement of multiple generating units in a limited space. The conical hole 131 extending along the axis means that the central axis of the hole channel coincides with the central axis of the columnar structure. Specifically, a tapered or flared conical channel can be formed through drilling or casting processes. This design can guide the air flow to form a continuous turbulent motion. The height being the same as the length of the conical hole 131 means that the longitudinal dimension of the columnar structure is the same as the developed length of the internal conical hole 131 channel. Specifically, the geometric ratio can be controlled by adjusting the mold forming parameters. This feature enables the air flow to maintain a complete expansion and contraction process when passing through the conical hole 131.

[0054] Specifically, when the columnar anion generating units 13 are arranged axially along the airtight sleeve 12, the conical holes 131 inside them form a continuous and through air flow channel. After the air enters from the air inlet, it flows through the conical holes 131 in each unit in turn. It accelerates in the tapered section to form a low-pressure area to promote the ionization of air molecules, and decelerates in the flared section to form a vortex to enhance the anion release. The structure with the unit height being the same as the length of the conical hole 131 avoids the energy loss of the air flow at the unit connection, ensuring that each conical hole 131 has a complete expansion and contraction effect on the air flow.

[0055] In addition, as Figure 5As shown, a spiral groove 132 is provided on the outer wall of the negative ion generating unit 13. The extending manner of the spiral groove 132 is the same as that of the Archimedean spiral. When air passes between the outer wall of the negative ion generating unit 13 and the inner wall of the airtight sleeve 12, due to the spiral groove on the outer wall of the negative ion generating unit 13, the air can come into full contact with the negative ion generating unit 13, thereby generating more negative ions.

[0056] As a preferred embodiment, as Figure 2 , Figures 4-6 shown, the tapered hole 131 includes a first end 1311 and a second end 1312. The first end 1311 faces the air inlet, and the second end 1312 faces the air outlet. The tapered hole 131 of this embodiment is a channel structure with a gradually changing cross-sectional size along the axial direction. Specifically, it can be implemented by a tapered structure with an increasing aperture from the air inlet direction to the air outlet direction. The acceleration and deceleration processes of the air flow in the tapered hole 131 promote the ionization of air molecules.

[0057] To achieve the connection and fixation of the negative ion generator 1 between the air filter and the carburetor, as Figures 1-4 shown, an air inlet connection pipe seat 14 is provided at the air inlet. An air inlet channel 141 is provided in the air inlet connection pipe seat 14, and the air inlet channel 141 is in communication with the tapered hole 131. Among them, the air inlet channel 141 is preferably columnar. The uniform cross-sectional design of the columnar air inlet channel 141 enables the air to form a stable laminar flow state when entering from the air inlet, avoiding the air pressure fluctuation caused by the sudden change of the channel shape.

[0058] The air inlet connection pipe seat 14 is a transition structure for connecting the external air source and the pipe body 11. In this embodiment, it refers to the air filter, which can be made of metal or high-temperature resistant plastic, and is fixed to the end face of the air inlet of the pipe body 11 by means of threads or buckles. A continuous and through channel structure is formed inside it to achieve the directional flow of gas. The air inlet channel 141 is a diversion cavity communicated with the tapered hole 131. Specifically, a columnar through hole can be formed by mechanical processing or molding, and its axis coincides with the axis of the tapered hole 131 to ensure the consistency of the gas flow direction.

[0059] Specifically, the air released by the air filter is guided into the tapered hole 131 through the air inlet channel 141 of the air inlet connection pipe seat 14, and undergoes continuous expansion and contraction processes in the tapered hole 131. Since the air inlet channel 141 is directly communicated with the tapered hole 131, the continuity of the gas flow path is ensured, avoiding the vortex or pressure loss caused by the sudden change of the air flow direction.

[0060] As a preferred embodiment, as Figures 1-4As shown, an air outlet connection pipe seat 15 is provided at the air outlet. An air outlet passage 151 is provided inside the air outlet connection pipe seat 15. The air outlet passage 151 is in communication with the conical hole 131, and the air outlet passage 151 is conical.

[0061] The air outlet connection pipe seat 15 is a connection component installed at the air outlet, used to fix and guide the gas flow, and is connected to the carburetor at the same time. Specifically, it can be made of metal or high-temperature resistant plastic to achieve a stable connection with the external pipeline. The air outlet passage 151 is an internal cavity that penetrates the air outlet connection pipe seat 15, used to export the gas processed by the conical hole 131. Specifically, it is designed as an expanding conical structure to adjust the air flow velocity.

[0062] In addition to including the negative ion generator 1, the negative ion combustion assistor for internal combustion engines of the present invention further includes a fixer 2, as Figure 1 shown. The fixer 2 is a support component used to fix the negative ion generator 1. Specifically, it can be realized by a ring-shaped or arc-shaped frame made of metal or high-strength plastic. Its structural shape is configured to match the installation space inside the internal combustion engine. In this embodiment, it is preferably in a ring-shaped structure.

[0063] As Figures 7-9 shown, a plurality of fixing parts 21 are provided on the fixer 2. The number of the fixing parts 21 is the same as the number of the negative ion generators 1. A clamping part 16 is provided on the outer wall of the negative ion generator 1, and the clamping part 16 is adapted to the fixing part 21.

[0064] Among them, the fixing part 21 is a connection structure provided on the fixer 2. Specifically, it can be realized by a U-shaped card slot, a clamping slot or a locking structure. Its number corresponds to the number of the negative ion generators 1 to achieve one-to-one positioning installation. The clamping part 16 is a matching structure provided on the outer wall of the negative ion generator 1. Specifically, it can be realized by a protrusion, a groove or a locking mechanism with an elastic member, and realizes quick installation and disassembly by being complementary to the shape of the fixing part 21.

[0065] Specifically, the fixer 2 is configured as a ring-shaped structure or an arc-shaped structure to adapt to the installation environment of the internal pipeline inside the internal combustion engine. The fixing parts 21 are evenly distributed in the circumferential or arc direction of the fixer 2, and each fixing part 21 corresponds to an installation position of a negative ion generator 1. The outer wall of the negative ion generator 1 is processed with a clamping part 16 matching the fixing part 21, such as a protrusion or a groove structure. When the negative ion generator 1 is inserted into the fixing part 21, the clamping part 16 and the fixing part 21 are locked through mechanical interference or elastic deformation. Thus, multiple negative ion generators 1 can be centrally fixed at a preset position to avoid displacement caused by vibration or air flow impact.

[0066] In some embodiments, the retainer 2 can be designed as a split ring structure, for example, consisting of two semicircular components bolted together, to facilitate installation in confined spaces. The retaining portion 21 can be a U-shaped slot structure with its opening facing outward. The engaging portion 16 is designed as an arc-shaped protrusion that fits against the inner wall of the slot, allowing for securement by rotation or pressing.

[0067] The negative ion combustion aid for internal combustion engines of the present invention is suitable for cars, large and small buses, large and small trucks, engineering vehicles, motorcycles and ships, etc. It has six major functions, namely, saving fuel and energy, enhancing power, reducing exhaust emissions, increasing engine life, being safe and reliable, and having non-destructive installation.

[0068] (1) Fuel saving and energy saving: Fuel saving is 10% to 30%, depending on the vehicle type and road conditions.

[0069] (2) Environmental protection and emission reduction: Complete combustion of oil or gas reduces exhaust gas emissions, including carbon monoxide by more than 40%, hydrocarbons by more than 30%, nitrogen oxides by more than 40%, and PM fine particulate matter by more than 20%.

[0070] (3) Enhanced power: Increase engine power and torque by more than 30%, significantly improving vehicle acceleration.

[0071] (4) Safe and reliable: The product has passed 50,000 km road test, 20,000 hours bench test, and national quality inspection agency inspection. As an engine air intake system component, it complies with the JB / T9747-2005 automotive parts safety standard and the "Engine Air Intake System Design Specification" requirements; it complies with the EU CE certification, the US UL and ETL certification, and the Canadian CSA certification requirements.

[0072] (5) Increase engine life: After ionization and activation, the negative ions in the air enter the high-temperature internal combustion engine and participate in the continuous combustion reaction. The active negative ions can capture the attachments and fine particle mixtures on the inner wall surface of the internal combustion engine (remove carbon deposits), thereby greatly reducing the probability of carbon deposits, thereby enhancing the lubricity of the engine oil, reducing engine wear and extending engine life.

[0073] (6) Non-destructive installation: Installed in the connecting pipe between the air filter and the engine, no need to modify any structure.

[0074] The negative ion combustion aid for internal combustion engines of the present invention can be fixed in the air filter hoses of different types of internal combustion engines. The specific installation and testing steps are as follows:

[0075] (1) Installation: First, remove the connection between the air filter and the intake pipe. Then, using four symmetric points, fix the side of the flared part of the present invention to the air intake pipe opening, inside the intake pipe, or the inner wall of the throttle intake pipe towards the air filter side evenly, such that the air outlet of the negative ion combustion promoter is 5 - 15 cm away from the throttle valve, allowing part of the air to enter the engine through the negative ion combustion promoter for internal combustion engines. It is better to perform a routine maintenance cleaning, replace the air filter element and spark plugs on the vehicle before installation.

[0076] (2) Testing: Start the engine, increase the speed to 2500 rpm and keep it for 5 minutes, then increase it to 3000 rpm and keep it for 3 minutes to let the black smoke exhaust; for ships and heavy vehicles, accelerate to 2000 rpm and keep it for 3 minutes to let the black smoke exhaust. Quickly and continuously step on and release the brake pedal ten times; repeat the above steps once; after completion, adjust the speed to 750 rpm and let the engine run continuously for a period of time or drive on the highway for a better effect.

[0077] Test results: The engine running sound is low, stable and powerful; there is no black smoke and no smell from the exhaust pipe; the brake pedal returns to a higher position more sensitively.
