Definitions
- This invention relates to methods for coupling two or more components and, in particular, to a method for coupling components of, but not limited to, a vehicle fuel delivery system and providing a fluid tight, pressurized joint.
- a conventional vehicle fuel system for use with a fuel injected internal combustion engine includes a filler neck assembly, a fuel tank, fuel lines, one or more fuel rails and fuel injectors. Fuel is input to the tank through the filler neck assembly (e.g., a fuel station). Fuel is supplied from the fuel tank to the fuel rail through the fuel lines where electronically controlled fuel injectors output fuel to the combustion chambers of the engine.
- a conventional fuel rail might have numerous components to couple together including a tubular rail, end caps, an inlet tube, mounting brackets and fuel injector cups.
- the brackets and cups are typically pre-staked to the tubular rail and holes are drilled through the cups.
- the caps, inlet tube, mounting brackets and cups are then brazed to the tubular rail.
- the assembly is fed through a brazing furnace to braze the various joints and is then cooled before testing, packaging and shipping.
- some assembled rails are also commonly subjected to plating or the application of a protective or reflective coating.
- the above-described process is, again, expensive and time-consuming.
- the heat requirements of the brazing furnace necessitate significant energy use and precise control of temperature and furnace atmosphere conditions.
- the brazing process itself also typically takes a relatively high amount of time (approximately 40 minutes for one conventional fuel rail).
- Hydro Aluminum Hycot USA Inc. has previously developed a nylon coated aluminum tube sold under the registered trademark “HYCOT” for use in various fluid handling applications including finished fuel lines. Further, Hydro Aluminum Hycot USA, Inc. has coupled other components to such tubes using an ultrasonic welding process. These components have been limited, however, to plastic brackets not involved in fuel transport and not requiring a fluid tight, pressurized joint.
- the inventors herein have recognized a need for a method for coupling components in a fluid handling system that will minimize and/or eliminate one or more of the above-identified deficiencies.
- the inventors herein have particularly recognized the ability to form a fuel system component as a laminated structure such as the “HYCOT” tubing and to couple other components to that component in such a way as to form a strong, fluid tight joint that is capable of withstanding pressurized applications without the need for complex mechanical seals while simultaneously reducing the cost and time of conventional manufacturing processes such as brazing or plastic injection molding.
- the present invention relates to a method for coupling first and second components of a fluid handling system.
- a method in accordance with the present invention includes the step of providing the first component, the first component including a tubular body defining a fluid passageway and formed as a laminate having an inner metallic layer and an outer polymeric layer.

Abstract
Description
- 1. Field of the Invention
- This invention relates to methods for coupling two or more components and, in particular, to a method for coupling components of, but not limited to, a vehicle fuel delivery system and providing a fluid tight, pressurized joint.
- 2. Discussion of Related Art
- A conventional vehicle fuel system for use with a fuel injected internal combustion engine includes a filler neck assembly, a fuel tank, fuel lines, one or more fuel rails and fuel injectors. Fuel is input to the tank through the filler neck assembly (e.g., a fuel station). Fuel is supplied from the fuel tank to the fuel rail through the fuel lines where electronically controlled fuel injectors output fuel to the combustion chambers of the engine.
- Manufacturing of conventional fuel system components is an expensive and time-consuming process. Many components are formed from metal alloys such as steel (although some fuel and vapor lines have been made using plastic coated aluminum). A conventional fuel rail might have numerous components to couple together including a tubular rail, end caps, an inlet tube, mounting brackets and fuel injector cups. The brackets and cups are typically pre-staked to the tubular rail and holes are drilled through the cups. The caps, inlet tube, mounting brackets and cups are then brazed to the tubular rail. The assembly is fed through a brazing furnace to braze the various joints and is then cooled before testing, packaging and shipping. For aesthetics, corrosion resistance, and other reasons, some assembled rails are also commonly subjected to plating or the application of a protective or reflective coating. The above-described process is, again, expensive and time-consuming. The heat requirements of the brazing furnace necessitate significant energy use and precise control of temperature and furnace atmosphere conditions. The brazing process itself also typically takes a relatively high amount of time (approximately 40 minutes for one conventional fuel rail).
- Hydro Aluminum Hycot USA Inc. has previously developed a nylon coated aluminum tube sold under the registered trademark “HYCOT” for use in various fluid handling applications including finished fuel lines. Further, Hydro Aluminum Hycot USA, Inc. has coupled other components to such tubes using an ultrasonic welding process. These components have been limited, however, to plastic brackets not involved in fuel transport and not requiring a fluid tight, pressurized joint.
- The inventors herein have recognized a need for a method for coupling components in a fluid handling system that will minimize and/or eliminate one or more of the above-identified deficiencies. The inventors herein have particularly recognized the ability to form a fuel system component as a laminated structure such as the “HYCOT” tubing and to couple other components to that component in such a way as to form a strong, fluid tight joint that is capable of withstanding pressurized applications without the need for complex mechanical seals while simultaneously reducing the cost and time of conventional manufacturing processes such as brazing or plastic injection molding.
- The present invention relates to a method for coupling first and second components of a fluid handling system.
- A method in accordance with the present invention includes the step of providing the first component, the first component including a tubular body defining a fluid passageway and formed as a laminate having an inner metallic layer and an outer polymeric layer. The component may, for example, comprise a fuel filler neck or a fuel rail. The method further includes the step of positioning the second component relative to the first component. This step may include the substep of aligning fluid apertures in the first and second components. The method further includes the step of moving one of the first and second components relative to another of the first and second components to generate heat and deform the outer layer of the first component and bond the second component to the first component while forming a fluid tight joint. Finally, the method includes the step of forming a fluid passageway between the first and second components at the joint.
- A method in accordance with the present invention has significant advantages relative to conventional manufacturing methods for fuel system components. The bonded joints for the parts of a fuel rail or other component can be formed in under one (1) minute as compared to the typical 15-40 minutes required for a furnace brazing operation. Moreover, the process does not require the significant energy use, precise control of temperature and furnace atmosphere conditions or considerable processing time of a furnace brazing operation. Further, the appearance and composition of the component eliminates the need for plating and/or painting of the component prior to shipping to the customer, since the external surfaces that are normally exposed to the ambient environment-including the bonded joint itself—are completely covered by the polymer laminate coating.

FIG. 4 , a method in accordance with the present invention is described and illustrated. The method includes the step 46 of providing a component having a tubular body and defining a fluid passageway that is formed as a laminate having an inner metallic layer and an outer polymeric layer. This component may, for example, compriseneck 26 orside tube 28 offiller neck assembly 14,fuel line 18, orbody 30 offuel rail 22. The component has a tubular body (e.g.,body 30 offuel rail 22 inFIGS. 2-3 ). The component defines a fluid passageway (e.g.,fluid chamber 32 in body 30) in which fuel or another fluid may be stored and/or through which fuel or another fluid may be transported. Referring toFIG. 3 (illustrating a portion ofbody 30 of fuel rail 22), the component includes inner andouter layers layer 48 relative to layer 50. It should be understood that additional laminate layers may be formed inwardly ofinner layer 48 or between inner andouter layers layers Inner layer 48 is metallic.Layer 48 may comprise steel. In apreferred embodiment layer 48 comprises aluminum.Outer layer 50 is polymeric and may comprise a plastic and, in particular, a thermoplastic.Outer layer 50 may or may not include a metallic or carbon or other non-metallic filler. In a preferred embodiment,outer layer 50 comprises nylon. Nylon refers to a family of polyamides generally characterized by the presence of the amide group, —CONH. In a preferred embodiment, the nylon is of a type known asnylon 12. It should be understood, however, that the type of nylon may vary and may be conductive (e.g., through the addition of carbon black) or non-conductive.Outer layer 40 may be pre-bonded to theinner layer 38 and may be extruded over theinner layer 38. In one constructed embodiment, the component is formed from nylon coated aluminum tubing sold under the registered trademark “HYCOT” by Hydro Aluminum Hycot USA, Inc. The aluminum inner layer of the tubing has a thickness of about 0.1 to about 1.2 mm. The nylon outer layer of the tubing has a thickness of between about 80 and about 500 microns and may measure about 150 microns. - Referring again to
FIG. 4 , the method may continue with thestep 52 of positioning another component relative to the component described above. Where the first component comprises aneck 26 ofassembly 14, the second component may comprise, for example, cup assembly 24,side tube 28, a grounding strap or a flexible coupling betweenneck 26 andtank 16. Where the first component comprisesbody 30 offuel rail 22, the second component may, for example, comprise anend cap inlet tube 40, a valve, afuel injector pod 42 or a mounting bracket 44 as shown inFIGS. 2-3 . As shown inFIG. 2 , step 52 may include the substep of aligningfluid apertures - The method may continue with the
step 58 of moving one of the components relative to another of the components (e.g.,body 30 relative to endcap 38 inFIG. 3 ) to generate frictional heat in a form of vibrational welding, ultrasonic welding or spin welding and thereby deform theouter layer 50 of the laminated component (body 30 inFIG. 3 ) and bond the other component (end cap 38 inFIG. 3 ) to the laminated component while forming a fluid tight, pressurized joint. This step may include the substep of applying supplemental heat from a conventional heat source. Referring toFIG. 3 , the relative movement bonds the two components by forming a joint 60 between the two components that has significant strength. In fact, testing has shown that joint 60 is stronger than even the metallicinner layer 48 of the laminated component when submitted to pressure, pull and twist forces. The joint 60 also forms a hermetic seal such that fluid handling components may have fluid inlets and outlets sealingly coupled as shown inFIG. 2 (seefluid apertures 54, 56). Although the above description referred to formation of a single joint, it should be understood that multiple joints could be formed substantially simultaneously. In particular, multiple components could be positioned in step 52 (e.g., end caps 36 and 38 relative tobody 30 of fuel rail 22) and joints formed substantially simultaneously in step 58 (allowing for slight time variation in formation of the bonds for components made from different materials). Alternatively, multiple components could be joined sequentially rather than substantially simultaneously. Further, it should be understood that the components being bonded to the laminated component may be made from a variety of materials. End caps 36, 38 andpods 42 may be made from plastics, for example. Alternatively, the inventors have discovered that metallic components, and particularly aluminum components, can be bonded in the same manner. In this case, the bond integrity between the metallic component and the laminated component may be optionally improved by preconditioning of the surfaces of the metallic component. Suitable conditioning treatments may include chemical etching by caustic or acid solutions, or by mechanical roughening or machining, including machined features such as ridges that may promote penetration of the mating polymeric material during heating and laminate deformation. In particular, a mechanical lip or stop or radial bend may be provided which is for example, bent over or formed within the connection after or duringstep 58. These mechanical structures resist high pressure stresses and/or shift bending stresses away from the joint. The structure could be formed in the laminated component and received within a corresponding recess in the metallic component. The inventive method has several advantages for fitting to line connections as compared to traditionally brazed aluminum connections for use in fluid handling applications such as aluminum fuel lines or fuel cooling, air-conditioning lines, power steering lines, and engine cooling or oil cooling applications. First, the laminated tubing described herein can be used without the otherwise prohibitive temperatures involved in brazing (that would destroy the plastic coating). Second, high strength aluminum fittings (such as AA 6XXX, 5XXX or 7XXX alloys) can be used in the inventive method. These alloys are difficult to use in conventional “CAB” or Nocolok™ fluoride salt flux type brazing (whether furnace, flame or induction brazing) because the process limits the addition of Magnesium strengthening additions in the aluminum alloy that otherwise poison the flouride flux, or the temperature limits of the alloy (7xxx for example) are to low for conventional brazing. - The method may continue with the
step 62 of forming a fluid passageway 64 between the components at the joint. Referring again toFIG. 2 , a joint may be formed betweeninjector pod 42 andtubular body 30 infuel rail 22 following the above described steps. A fluid passageway 64 may be then be punched throughpod 42 andbody 30 or otherwise formed in a variety of conventional ways. The fluid tight, pressurized joint betweenpod 42 andbody 30 prevents fluid from leaking as it moves frombody 30 topod 42 through passageway 64. - A method in accordance with the present invention has significant advantages relative to conventional manufacturing methods for fuel system components. The
joints 60 formed by the inventive method are formed rapidly—typically in under one (1) minute as compared to the typical 15-40 minutes required for a brazing operation. The inventive method also does not require the significant energy use, precise control of temperature and furnace atmosphere conditions or considerable processing time of a furnace brazing operation. Further, the appearance and composition of the component eliminates the need for plating and/or painting of the component prior to shipping to the customer, since the external surfaces that are normally exposed to the ambient environment-including the bonded joint itself—are completely covered by the polymer laminate coating. - While the invention has been shown and described with reference to one or more particular embodiments thereof, it will be understood by those of skill in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.
