Description

Technical Field

[0001] This application relates to the automotive field, and more particularly to a filtration device, a fuel supply system, and a vehicle. Background Technology

[0002] A fuel supply system typically consists of a fuel tank, a coarse filter, a methanol pump, a pressure regulating valve, a fine filter, a drain solenoid valve, and a fuel rail. These components work together to form a liquid circulation system for efficient fuel supply.

[0003] Excessive moisture in methanol fuel can exacerbate the corrosive effects of methanol on metals, reducing the functionality and reliability of components in the engine and its accessory systems. Furthermore, excessive moisture content can worsen methanol combustion and exhaust emissions, while also causing excessive moisture in the oil pan, reducing oil lubrication performance and exacerbating oil emulsification. Utility Model Content

[0004] The purpose of this application is to provide a filtration device, a fuel supply system, and a vehicle.

[0005] According to a first aspect of the embodiments of this application, a filtration device is provided, the filtration device having an inlet and an outlet, the filtration device comprising:

[0006] The housing includes a receiving space, and the liquid inlet and liquid outlet are respectively connected to the receiving space;

[0007] A filter section is disposed within the accommodating space and isolates the inlet and the outlet. The filter section is used to filter water molecules.

[0008] The liquid enters the containing space through the inlet, passes through the filter, and flows out through the outlet.

[0009] It should be noted that the filtration section here can employ the aforementioned water molecule sieve, semi-permeable membrane, etc., to remove water molecules from the liquid. The aforementioned housing can be a filter cup, filter barrel, or other device with space. Furthermore, the aforementioned filtration device may also include components such as a filter base and a locking ring. The filter base serves as a base structure, providing an mounting structure for the housing, locking ring, and filtration section, and also integrates an inlet and outlet. The locking ring is a locking mechanism that secures the housing to the filter base.

[0010] Because the filter unit isolates the inlet and outlet, all liquid entering from the inlet and exiting from the outlet is filtered by the filter unit, thus removing water molecules. Compared to traditional methanol fuel supply systems, this technology reduces the corrosiveness of methanol to metals, improves the reliability of the engine and its components, ensures proper methanol combustion and engine exhaust emissions, and simultaneously reduces the water content in the engine oil, lowering the risk of oil emulsification.

[0011] In some embodiments, the filtration unit includes at least one first filtration unit and at least one second filtration unit, wherein the first filtration unit is used to filter water molecules and the second filtration unit is used to filter impurities.

[0012] It should be noted that the first filtration unit here can be the aforementioned water molecule sieve, semi-permeable membrane, etc., and the second filtration unit can be filter paper, such as qualitative filter paper, quantitative filter paper, activated carbon filter paper, and polypropylene filter paper.

[0013] Based on the above setup, water molecules in the fuel can be filtered out, as well as impurities. Removing water molecules reduces the corrosiveness of methanol to metals, improving the reliability of components in the engine and fuel supply system. Simultaneously, removing impurities reduces the potential for wear and tear on the engine's internal components, such as dust and metal particles, which could affect normal operation and shorten its lifespan. Removing these impurities effectively reduces the wear rate of mechanical parts, protecting precision components from damage.

[0014] In some embodiments, the second filter unit includes adjacently disposed protrusions and recesses, and a fixed space is formed in the recesses, wherein the first filter unit is disposed in the fixed space;

[0015] The liquid is filtered by the first filtration unit in the fixed space, and then filtered by the second filtration unit.

[0016] Based on the above configuration, the second filter unit has both protrusions and recesses. This structure significantly increases the contact area with the outside compared to a single-sided unit, thereby improving filtration efficiency. Furthermore, the first filter unit is positioned in a fixed space, which prevents movement between the first and second filter units under liquid impact, thus improving the stability of the device.

[0017] In some embodiments, the second filter unit is arranged in a ring, and there are multiple protrusions and multiple recesses. The multiple protrusions and multiple recesses are arranged in a ring around the second filter unit, and multiple fixed spaces are formed on the outside of the second filter unit. The first filter unit is disposed in the fixed spaces.

[0018] Multiple protrusions and recesses further increase the contact area with the outside, thereby improving filtration efficiency. Furthermore, the formation of multiple fixed spaces prevents crosstalk between the first filter units located in different fixed spaces, thus preventing a reduction in the effectiveness of filtering water molecules.

[0019] In some embodiments, the first filtering unit includes a plurality of sub-units, and the plurality of sub-units located in the same fixed space are fixedly arranged with each other.

[0020] The multiple sub-units are fixed together, which prevents their positions from constantly changing and affecting their water removal function. Furthermore, the fixed arrangement of the sub-units simplifies installation; simply placing the entire set of sub-units into the designated space completes the installation, and removing them is as simple as detaching them from the space. This process is straightforward and saves on installation and disassembly costs.

[0021] In some embodiments, the first filtering unit includes a plurality of sub-units, the sub-units being configured as spherical.

[0022] The sub-unit is spherical, which maximizes its contact area with the fuel compared to other shapes, thereby filtering out more water molecules and achieving a better water removal effect.

[0023] In some embodiments, the first filter unit and the second filter unit are fixedly arranged.

[0024] Based on the above setup, since both the first and second filter units are consumable materials and need to be replaced after a certain period of filtration, fixing them together can increase replacement efficiency and improve the user experience.

[0025] According to a second aspect of the present application, a fuel supply system is provided, comprising: a fuel tank, a pumping device, and a filtering device as described in any of the above embodiments;

[0026] The fuel tank is used to store fuel;

[0027] The pump device is connected to the fuel tank and is used to transport the fuel and form a liquid circulation with the fuel tank;

[0028] The filtration device is located on the path of the liquid circulation and is used to filter water molecules in the fuel.

[0029] It should be noted that water molecule sieves can be arranged in the filtration device. These sieve particles are a type of granular desiccant with a uniform microporous structure on their surface. The pore size is similar to the diameter of a water molecule, giving them a strong affinity for water molecules. They efficiently adsorb moisture under various conditions, reducing the moisture content in methanol to very low levels. This type of sieve is specifically designed for water molecules and possesses extremely strong chemical, thermal, and mechanical stability. Alternatively, other substances that remove water molecules can be used, such as membrane separation technology, primarily including reverse osmosis and nanofiltration. These technologies utilize the selective permeability of semi-permeable membranes, allowing water molecules to pass through while blocking other large molecules.

[0030] Based on the above setup, water molecules in the fuel can be filtered out. Compared with traditional methanol fuel supply systems, this technology reduces the corrosiveness of methanol to metals, improves the reliability of components in the engine and supply system, ensures normal methanol combustion and engine exhaust emissions, and reduces the water content in engine oil, thus reducing the risk of oil emulsification.

[0031] In some embodiments, the number of the filtration devices is multiple, and the multiple filtration devices are respectively arranged on the liquid circulation path.

[0032] Multiple filtration devices can more thoroughly filter out water molecules from the fuel, thus achieving a better water molecule removal effect. Furthermore, designers can install filtration devices at different locations according to actual needs. For example, filtration can be performed when methanol enters the fuel tank and again when it leaves the fuel supply system, thus achieving filtration at both the beginning and end of the fuel supply system for a more comprehensive filtration effect.

[0033] According to a third aspect of the embodiments of this application, a vehicle is provided, the vehicle including a fuel supply system as described in any of the above embodiments.

[0034] The beneficial technical effects of the technical solutions provided in this application are:

[0035] The system comprises a housing and a filter. The housing includes a receiving space, with an inlet and an outlet respectively connected to the receiving space. The filter is disposed within the receiving space and isolates the inlet and outlet. The filter is used to filter water molecules. Liquid enters the receiving space through the inlet, passes through the filter, and then flows out through the outlet.

[0036] Based on the above setup, water molecules in the fuel can be filtered out. Compared with traditional methanol fuel supply systems, this technology reduces the corrosiveness of methanol to metals, improves the reliability of components in the engine and supply system, ensures normal methanol combustion and engine exhaust emissions, and reduces the water content in engine oil, thus reducing the risk of oil emulsification.

[0065] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0066] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0067] The vehicle mainly includes a fuel supply system 10, an engine system, an intake system, an exhaust system, a cooling system, a lubrication system, an electronic control system, and other components, which work together closely to enable the vehicle to function.

[0068] The fuel supply system 10 is a crucial component of the automotive engine system. Its primary function is to ensure the engine receives the appropriate amount and pressure of fuel for efficient combustion. The engine system is the heart of the vehicle, converting the energy of fuel into mechanical energy. The fuel supply system 10 is responsible for supplying the engine with the correct amount of fuel, which the engine then burns to generate power. The intake system supplies air to the engine, which mixes with fuel inside the engine to form a combustible mixture. A suitable air-fuel ratio is essential for the engine's efficient operation. The exhaust system is used to effectively expel the exhaust gases after combustion from the engine. The exhaust system not only helps remove exhaust gases but also reduces harmful emissions through a catalytic converter. The cooling system maintains the engine within a safe operating temperature range. This helps protect the engine from overheating and maintains its performance. The lubrication system, by circulating oil throughout the engine, reduces friction between moving parts, lowers wear, and extends engine life. The electronic control system monitors and adjusts various parameters, including fuel supply, ignition timing, and air-fuel ratio, to optimize engine performance and fuel efficiency.

[0069] The aforementioned fuel supply system 10 typically consists of a fuel tank 200, a coarse filter 700, a pump unit 300, a pressure regulating valve 400, a fine filter 800, a drain solenoid valve 500, and a fuel rail 600. These components form a liquid circulation system for efficient fuel supply.

[0070] The system includes: a fuel tank 200 for storing methanol fuel and providing mounting locations for components such as a level gauge, breather valve, and filler neck; a coarse filter 700 connected to the fuel tank 200 outlet via a methanol pipeline to filter and store moisture and impurities from the methanol fuel; a pump unit 300 for fuel transport and circulation, providing an oil line interface; a pressure regulating valve 400 for regulating and stabilizing system pressure, providing a stable pressure of fuel to the engine, and providing an oil line interface; a fine filter 800 for providing secondary filtration of the fuel, filtering moisture and impurities, and providing an oil line interface and a drain port; a drain solenoid valve 500 for venting and opening / closing the return oil channel after fine filtration, and providing an oil line interface; and a fuel rail 600 for fuel distribution, providing an injector mounting and fixing structure, and providing an oil line interface.

[0071] Excessive moisture in methanol fuel can exacerbate the corrosive effects of methanol on metals, reducing the functionality and reliability of components in the engine and its accessory systems. Furthermore, excessive moisture content can worsen methanol combustion and exhaust emissions, while also causing excessive moisture in the oil pan, reducing oil lubrication performance and exacerbating oil emulsification.

[0072] This application proposes a fuel supply system 10, with reference to... Figure 5 and Figure 6As shown, the fuel supply system 10 includes a fuel tank 200, a pump unit 300, and a filter unit 100. The fuel tank 200 is used to store fuel, the pump unit 300 is connected to the fuel tank 200 and is used to transport fuel and form a liquid circulation with the fuel tank 200, and the filter unit 100 is disposed in the path of the liquid circulation and is used to filter water molecules in the fuel.

[0073] It should be noted that the filtration device 100 can be equipped with water molecule sieves. These sieve particles are granular desiccants with a uniform microporous structure on their surface. The pore size is similar to the diameter of water molecules, giving them a strong affinity for water molecules. They efficiently adsorb moisture under various conditions, reducing the moisture content in methanol to very low levels. This type of sieve is specifically designed for water molecules and possesses extremely strong chemical, thermal, and mechanical stability. Alternatively, other substances that remove water molecules can be used, such as membrane separation technologies, primarily including reverse osmosis and nanofiltration. These technologies utilize the selective permeability of semi-permeable membranes to allow water molecules to pass through while blocking other large molecules.

[0074] Based on the above setup, water molecules in the fuel can be filtered out. Compared with traditional methanol fuel supply systems, this technology reduces the corrosiveness of methanol to metals, improves the reliability of components in the engine and supply system, ensures normal methanol combustion and engine exhaust emissions, and reduces the water content in engine oil, thus reducing the risk of oil emulsification.

[0075] In some embodiments, reference Figure 5 As shown, the number of filter devices 100 can be set to multiple, and multiple filter devices 100 are respectively arranged on the liquid circulation path.

[0076] Multiple filtration devices 100 can more thoroughly filter out water molecules in the fuel, thus achieving a better water molecule removal effect. In addition, the designer can set the filtration devices 100 at different locations according to actual needs. For example, filtration can be carried out when methanol enters the fuel tank 200 and again when methanol leaves the fuel supply system 10, so that filtration is carried out at both the beginning and end of the process, thereby achieving a more comprehensive filtration effect.

[0077] Based on the above settings, this application can be deployed in the following manner: Figure 6 As shown, a separate filtration device 100 is installed in the liquid circulation system without altering other devices in the original fuel supply system 10. See also... Figure 5 As shown, the filter components are integrated with the original coarse filter 700 and the original fine filter 800 to form a new filter device 100, the specific structure of which will be shown in detail below.

[0078] refer to Figures 1-4 As shown, this application proposes a filtration device 100, which includes an inlet 110, an outlet 120, a housing 130, and a filter section 140. The housing 130 includes a receiving space 131, and the inlet 110 and outlet 120 are respectively connected to the receiving space 131. The filter section 140 is disposed within the receiving space 131 and isolates the inlet 110 and outlet 120. The filter section 140 is used to filter water molecules. Liquid enters the receiving space 131 through the inlet 110, passes through the filter section 140, and flows out through the outlet 120.

[0079] It should be noted that the filtration section 140 here can employ the aforementioned water molecule sieve, semi-permeable membrane, etc., to remove water molecules from the liquid. The aforementioned housing 130 can be a filter cup, filter barrel, or other device with space. Furthermore, the aforementioned filtration device 100 may also include components such as a filter base and a locking ring. The filter base is a base structure that provides an mounting structure for the housing 130, locking ring, and filtration section 140, and also integrates an inlet 110 and an outlet 120. The locking ring is a locking mechanism that fixes the housing 130 to the filter base.

[0080] Because the filter section 140 isolates the inlet 110 and the outlet 120, all liquid entering from the inlet 110 and flowing out from the outlet 120 will be filtered by the filter section 140, meaning water molecules will be filtered out. Compared to traditional methanol fuel supply systems, this technology reduces the corrosiveness of methanol to metals, improves the reliability of the engine and its components, ensures proper methanol combustion and engine exhaust emissions, and simultaneously reduces the water content in the engine oil, thus lowering the risk of oil emulsification.

[0081] In one embodiment, reference Figures 2-4 As shown, the filtration unit 140 includes at least one first filtration unit 141 and at least one second filtration unit 142. The first filtration unit 141 is used to filter water molecules, and the second filtration unit 142 is used to filter impurities. It should be noted that the number of first filtration units 141 and second filtration units 142 can be one or more, and the number can be adjusted according to actual conditions. Furthermore, the order in which the liquid passes through the first filtration unit 141 and the second filtration unit 142 is not limited in this application.

[0082] It should be noted that the first filtration unit 141 here can be the aforementioned water molecule sieve, semi-permeable membrane, desiccant particles, etc., and the first filtration unit 141 can be reused after being baked at high temperature; the second filtration unit 142 can be filter paper, such as qualitative filter paper, quantitative filter paper, activated carbon filter paper, and polypropylene filter paper.

[0083] Based on the above setup, water molecules in the fuel can be filtered out, as well as impurities. Removing water molecules reduces the corrosiveness of methanol to metals, improving the reliability of components in the engine and fuel supply system. Simultaneously, removing impurities reduces the potential for wear and tear on the engine's internal components, such as dust and metal particles, which could affect normal operation and shorten its lifespan. Removing these impurities effectively reduces the wear rate of mechanical parts, protecting precision components from damage.

[0084] In one embodiment, reference Figure 3 and Figure 4 As shown, the second filter unit 142 includes an adjacent protrusion 142A and a recess 142B, and a fixed space 143 is formed in the recess 142B. The first filter unit 141 is disposed in the fixed space 143. The liquid is filtered by the first filter unit 141 in the fixed space 143, and then filtered by the second filter unit 142.

[0085] Based on the above configuration, the second filter unit 142 is provided with a protrusion 142A and a recess 142B. This structure significantly increases the contact area with the outside compared to having only one surface, thereby improving the filtration efficiency. In addition, the first filter unit 141 is disposed in the fixed space 143, which can also prevent the relative positions of the first filter unit 141 and the second filter unit 142 from shifting under liquid impact, thereby improving the stability of the device.

[0086] In one embodiment, reference continues Figure 3 and Figure 4 As shown, the second filter unit 142 is arranged in a ring, with multiple protrusions 142A and multiple recesses 142B. The multiple protrusions 142A and multiple recesses 142B are arranged in a ring on the second filter unit 142, and multiple fixed spaces 143 are formed on the outside of the second filter unit 142. The first filter unit 141 is disposed in the fixed space 143.

[0087] Multiple protrusions 142A and multiple recesses 142B further increase the external contact area, thereby improving filtration efficiency. Furthermore, since multiple fixed spaces 143 are formed, crosstalk between the first filter units 141 located in different fixed spaces 143 can be prevented, thus preventing a reduction in the effectiveness of filtering water molecules.

[0088] In one embodiment, reference Figures 2-4 As shown, the first filter unit 141 includes multiple sub-units 141A, which are fixedly arranged in the same fixed space 143.

[0089] The multiple sub-units 141A are fixedly arranged together. This prevents their positions from constantly changing, which could affect their moisture removal function. Furthermore, the mutual fixation of the sub-units 141A means that installation is simple; the entire set of sub-units 141A is placed into the fixed space 143. Disassembly is equally simple; the entire set of sub-units 141A is removed from the fixed space 143. This process is straightforward and saves on installation and disassembly costs.

[0090] In one embodiment, reference Figure 2 and Figure 4 As shown, the first filtering unit 141 includes multiple sub-units 141A, and the sub-units 141A are configured to be spherical.

[0091] Subunit 141A is spherical, which maximizes its contact area with fuel compared to other shapes, thereby filtering out more water molecules and achieving better water removal.

[0092] In one embodiment, reference Figures 1-4 As shown, the first filter unit 141 and the second filter unit 142 are fixedly arranged.

[0093] Based on the above settings, since both the first filter unit 141 and the second filter unit 142 are consumable materials and need to be replaced after filtering for a certain period of time, fixing the two together can increase the replacement efficiency and improve the user experience.

[0094] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
