Description

[Detailed description of the invention] This invention relates to a bypass oil refiner for an internal combustion engine. .

Bypass oil refiner is used in automobiles and other machines using internal combustion engines. An alternative route for lubricating oil flow is coupled to the crankcase of the internal combustion engine. oil riff The oil filter filters the oil through a porous filter material, heats the oil, and Evaporates and removes volatile contaminants such as water and fuel.

Background technology Contaminated lubricating oil used in internal combustion engines and other equipment can be This is the main cause of excessive wear and deterioration of equipment. Currently, most internal combustion engines are lubricated. Extracts substances like dust, carbon, soot, metal particles and other similar foreign substances from oil Therefore, only conventional mechanical filters are used. condensate, water and fuel Liquid contaminants, such as cannot be separated. Therefore, contaminants that enter the engine can cause Internal combustion engines that use such mechanical filters to minimize engine damage Seki's lubricating oil often needs to be changed.

In recent years, due to the rise in the global price of petroleum products, lubricating oil has been used indefinitely. A fine system is opened to regenerate the lubricating oil so that it can be reused. It is essential that it be issued. This method requires only a small amount of additional lubrication Only ile is required in engine applications.

The problems with liquid contaminants have been recognized and mechanisms for separating oil and contaminants have been developed. Efforts are being made to develop devices that use heat as a mechanism. This is typical of this kind The devices up to this point were manufactured by Schwalzi (Schwa 1 ge) in the United States. Permission number sections 2,635,759, 2,785,109 and 2,839,19 6. U.S. Patent No. 3.550 for Barrrow , 871, Priest U.S. Patent No. 3.616. ゜885, No. 3,915,860 and No. 4,006,084, Forsland (Forsland), U.S. Patent No. 4,146,475, and My prior United States Patent No. 4.349,438.

Problems that have previously prevented widespread use of oil refiners in automobiles There was a point. The main problem with conventional oil refiners is that Such equipment may not be able to adequately remove liquid contaminants trapped in the oil. That's a good thing. Therefore, conventional oil refiners generally suffer from solid contamination. Only marginally better than previous disposable filters that only remove substances . In conventional oil refining equipment, the engine lubricating oil is free from conventional solid contaminants. May only be used for a slightly longer period of time than with a rejection filter. . Peripheral oil recycling life resulting from removal of small amounts of fluid contaminants The improvement does not justify the higher cost of achieving this improvement. .

Disclosure of invention This invention is designed to remove liquid while the engine is in use and when the engine lubricating oil is recycled. Significantly improves the degree to which contaminants are removed from the engine lubricating oil We provide a system for As in conventional oil refiners, this invention The oil refiner also includes a filtration element to remove solid contaminants.

The oil refiner of this invention has a much higher degree of refinement than previously possible. Engine oil removes contaminants from liquids that were previously possible. can be used and reused for much longer periods of time.

The oil refiner of this invention has a decontaminated oil outleft. It is formed from an evaporation unit that defines an internal evaporation chamber. Conventional oil refurbishment As in the evaporator, an electric heating element heats the evaporation chamber. placed within the unit. Disposable, removable filter cartridge , removably coupled to the evaporator unit and contaminated oil inlet. and a decontaminated oil outlet. of decontaminated oil The outlet communicates directly with the filter oil inlet to the evaporator unit. Ru.

Unlike prior art, conventional oil refiners, the filtered oil is does not pass as a runoff liquid from the ment to the evaporation unit. In contrast, spraying hands A stage connects the filtered oil outlet of the filter cartridge and the evaporation chamber. between the filtered oil inlet and the filtered oil inlet. the simplest form The atomizing means should be thick enough to reach the evaporation chamber and allow the oil to pass through. has a sufficiently small diameter so that the oil is atomized as it enters the evaporation chamber; It is just an orifice. The spray must be at a meaningful pressure across the orifice. This is achieved by selecting the dimensions of the orifice to create a force difference. about An orifice with a diameter between 0.010 inch and about 0.125 inch is selected. The selected oil circulation rate will produce some atomization, but the preferred orifice diameter The range is between about 0.0135 inches and about 0.040 inches.

Orifice diameters smaller than 0.0135 inches typically Not enough oil to be recycled to remove contaminants resulting from operation. The flow velocity becomes high.

If the orifice diameter is greater than about 0.040 inches, no atomization will occur. or even if it occurs, it will be to a very small extent and will significantly shorten the engine oil life. It will not give you a long life.

The dimensions of the orifice depend on the degree of atomization and at the same time the flow rate of the oil through the refiner. It's a delicate balance to choose the right orifice dimensions because it controls both the There is. The selection of orifice dimensions also determines the distance between the filtration element and the evaporation chamber. Control the pressure difference. Therefore, in a preferred form of the invention, the , a wall or partition where the filtered oil inlet bounds the evaporation chamber. It is formed as a tapped bore in the hole. Bore with tap various plug-like, annular structures externally threaded for mating engagement with can be used interchangeably. For internal combustion engines where refiners should be used Therefore, various plugs with different orifice dimensions or configurations can be selected accordingly. may be selected and used in an oil refiner.

To achieve an oil flow rate of 6 gallons per hour, approximately 0.0135 in. to 0.01 in. A spray orifice size in the range of 0.030 inches is selected. For one orifice This creates a pressure difference between the pressure chamber and the evaporation chamber of approximately 49 psi. maintain. To achieve an oil flow rate of 12 gallons per hour with the same pressure difference, approximately An orifice size of 0.016 inch to 0.036 inch is selected. 60 To achieve a flow rate of 12 to 18 gallons per hour with a pressure difference of psL, approximately 0. An orifice size of 0.020 inches to approximately 0.038 inches should be selected. . To achieve a flow rate of 18 to 24 gallons per hour with a pressure differential of 80 psi, Orifice dimensions should be between approximately 0.024 inch and approximately 0.040 inch. No. To achieve a flow rate of 24 gallons per hour at 100 psi, the orifice The dimensions should be between about 0.024 inches and about 0.040 inches.

To determine the appropriate orifice size, a 0.002 inch diameter orifice is commonly used. The change in fissure size is approximately 20% and 25% in the intermediate range of most desirable flow rates. Consideration should be given to varying the volumetric flow rate between % and %. must be considered Another factor that may not be considered is the thickness of the partition in which the spray nozzle is placed, which Oil must flow from the evaporation element to the evaporation chamber. This is because it has a long relationship with the length of the duct. The evaporation chamber is closed to the incoming oil. The thickness of the partition separating from the cell is approximately 0.01 at low pressure differentials such as 40 psl. Must be on the order of 0 inches. Partition thickness is 80 to 100ps Higher pressures such as i may increase up to 0.125 inches.

The oil-sprayed orifice dimensions of the oil refiner of this invention are achievable. As far as flow rate is concerned, it is the limiting factor. As a result, in order to achieve a suitable flow rate to provide an evaporation unit with multiple atomizing nozzles rather than a single nozzle. It may be desirable to do so. Multiple spray nozzles with smaller dimensions are often Can be used instead of a single spray nozzle with larger orifice size. can. For example, at a given flow rate, a 0.013 inch diameter orifice Three atomizing nozzles with a constant pressure between the filtration element and the evaporation chamber The force difference is approximately equal to one spray nozzle with a 0.030 inch diameter orifice. may be used to achieve the same flow rate.

Other variations of this invention form a filtered oil inlet into the evaporation chamber. Multiple orifices in one plug threaded into a bore with taps including using. A plug with one, central axial duct serves as a spray nozzle. Although it can be used to form the simplest embodiment of an evaporation chamber, from the side of the plug spaced from the bar, angled inwardly toward the center of the plug. Alternative nozzles with several ducts can also be used.

In yet another embodiment of the invention, the spray nozzle is threaded on its exterior. The plug may take the form of a cylindrical plug with radial slots defined in the wall. stomach. The longitudinal slots, of course, do not allow any oil, if any, to pass through. filtered oil into the evaporation chamber in order to It must be deeper than the thread pitch of the let.

A wide variety of spray nozzle configurations and sizes may be used within the scope of this invention. can be However, the essential feature of this invention is that the pressure chamber Restricts flow from a pressure chamber external to the evaporation chamber to create pressure. This means that a controlled spray nozzle is used.

The pressure from the pressure chamber acts on the oil and moves from the pressure chamber to the evaporation chamber. The oil flowing into the evaporation chamber is dispersed into atomized droplets that drift as a mist within the evaporation chamber. Conventional Unlike other oil refiners, the oil evaporates from the inlet according to this invention. Does not penetrate as a liquid into the chamber. On the contrary, it is sprayed as a mist into the evaporation chamber. Atomized and thereby trapped liquid contaminants are removed from traditional oil refinement systems. evaporated and oil to a much greater extent than was possible with stems. gives a much larger surface area to be removed.

Contaminated oil inlet 48 is located at the opposite end of filter cartridge 14. Placed.

The atomization assembly 36 directs the flow of oil from the pressure chamber 44 to the evaporation chamber 24. compresses the oil and atomizes the oil as stray droplets as it enters the evaporation chamber 24. A pressure is created in the pressure chamber 44 to cause the condition. Orifice of duct 40 The supply of suitable oil to the evaporation chamber 24 and through the oil refiner 10 dimensions large enough to allow flow rates, but with filtered oil inlets. The oil does not permeate as a liquid through the port 34 to the evaporation chamber 24, but rather evaporates. It is small enough to be atomized as an atomized mist into the emission chamber 24.

Atomization assembly 36 converts the filtered oil into a fine, atomized spray. This greatly increases the surface area of the oil and makes it more resistant to water and fuel. Liquid contaminants in the eel are more concentrated than possible in any conventional oil refiner. is also evaporated within the evaporation chamber 24 to a much greater extent.

The cover 22 of the evaporator unit 12 has an outer surface that surrounds the upper edge of the refiner head 28. It is formed from a stamped, sheet metal member having a circumferential rim. annular The cover plate gasket 50 is located between the cover 22 and the refiner head 28. forming an airtight seal. The periphery of the cover 22 is lifted with six machine screws 52. It is fixed to the finer head 28.

Transversely from a filtered oil inlet 34 containing a spray assembly 36, the evaporation a convexity extending into the evaporation chamber 24 within the evaporation unit 12 at a location within the chamber 24; A shaped protrusion 54 is formed. The convex protrusion 54 allows oil to pass through the evaporation chamber 24. helps to laterally disperse the atomized droplets.

The elbow of the electric heating element 20 bends upward and passes through the opening in the cover 22. . A gas-tight seal is maintained by a suitable retainer and insulating seal, and the heater Element 20 is attached to cover assembly 22 by retaining nut 56.

No. 4,349,438 is Also, planned oil contaminants can be discharged from the oil refiner 10. The cover 22 is fixed to the cover 22 so as to provide a ventilation hole for opening.

As best shown in FIGS. 1 and 3, the oil refiner 10 is It includes a mounting bracket 62 in the form of a yoke. Yoke-shaped mounting bracket 62 holds the refiner head 28 and attaches it with the removable fixing bolt 66. and has a handle 64 secured thereto. The shank of the bolt 66 is attached to the handle 64. Passing through the long slot 68, the oil refiner 10 changes over the wide range of the vehicle. Properly positioned and oriented within the model's engine compartment Can be done. Oil refiner 10 may be positioned in substantially any desired orientation. , since the oil in the evaporation chamber 24 can cross any particular plane. It does not need to flow as a liquid, but rather is atomized by the electric heating element 20. This is because it is converted into a format. Ultimately, the oil flows through the refiner head 28 The oil exits the refiner 10 through a radial bore 68 with a tap. Ru.

The container sealing gasket 82 prevents oil from entering the container 16 and the lift. This prevents leakage from between the main cabinets 1128.

A spray nozzle plug 38 is depicted in cross-section and separately in FIG. Figure 4 In the embodiment depicted in FIG. External threads are provided at 86 for engaging bushing 42 which can only be seen when I'm being kicked. As previously explained, compression of a single, central axial duct 40 The diameter of the orifice is preferably about 0.0135 inches to about 0.040 inches. It is between. By selecting the orifice diameter within this range, the duct 40 can be While ensuring a high degree of atomization of the oil discharging into the evaporation chamber 24, Satisfactory oil flow rates of through 10 are possible.

The duct 40 allows oil to exit the pressure chamber 44 as an atomized mist into an evaporative chamber. forming a compression aperture or nozzle that is forced upwardly into the chamber 24; The oil is It exits the oil evaporation chamber 24 as an atomized mist. Convex on the lower side of cover 22 The shaped protrusion 54 directs the atomized droplets of oil laterally through the evaporation chamber 24. It helps to disperse in the direction. The heating element 20 produces a large atomized droplet of oil. It acts on a large surface area and evaporates the liquid contaminants trapped there. oil has a boiling point far above that of the liquid contaminants found in oil, so The sprayed droplets of oil eventually reform as a liquid, as seen in Figure 1. The decontaminated oil passes through the outlet 68 to the evaporator unit 1. Released from 2.

Because there are severe restrictions on suitable orifice dimensions, as depicted in Figure 5. , it is desirable to provide a plurality of orifices 40' in one spray plug 38'. Sometimes there is.

Preferably each internal duct 40 has an orifice diameter between about 0.0135 inches and about 0.6040 inches. Ru. The flow rate of atomized oil flowing through each plug 96 is cumulative, so that Compared to one plug with orifice diameter, the flow rate is four times that of the first plug. This can be achieved in the embodiments of FIGS. 8 and 9. Other embodiments of this invention As in, the spray nozzle formed by the plug 96 is connected to the filter cart. Compressing the oil flow from the ridge 14 to the evaporation chamber 24 creates a pressure in the filter cartridge 14 that causes oil to flow from the filter cartridge 14 to the evaporation chamber 24. When entering, the liquid oil is atomized into floating droplets.
