Definitions
- This invention relates to fuel tanks, and more particularly to a low permeation fuel tank that includes internally mounted components.
- Fuel tanks made of plastic or metal are well known for providing a reservoir of fuel for engines and other fuel consuming devices in land, water and air vehicles.
- a hydrocarbon barrier is typically included in fuel tanks to prevent passage of fuel and associated vapors therethrough.
- Additional components are usually added to the fuel tank to create a fuel system.
- the components may include valves, hoses, pumps, level sensors, structural supports, etc. Typically, some of these components are installed inside the fuel tank by cutting service holes in the tank. In addition, some of the components are installed outside the tank requiring additional holes, grooves and/or recesses.
- Some fuel tanks are manufactured with a structure inside the tank.
- the structure provides for internalized mounting of fuel system components.
- the structure includes rigid columns that are rigidly connected with opposite walls of the fuel tank to maintain the structure in position. The columns are located to generally define the perimeter of the structure.
- the columns also provide local structural support for the fuel tank.
- the remaining structure is created with rigid members. Some of the rigid members include compliant joints to allow the otherwise rigid structure to distort in response to external forces. Such a structure is described in U.S. Pat. No. 6,138,859 to Aulph et al.
- columns to support the structure may require placement of columns where no structural support of the fuel tank is needed.
- columns may provide stiffness that hinders desirable crushing and/or folding characteristics of the fuel tank during an impact, such as in a crash situation.
- shearing and moment forces applied to only a portion of the tank, such as, for example, in a crash situation, may be transferred to another portion of the tank by the rigid nature of the columns causing additional damage.
- column placement required to support the structure may interfere with ribbing and other desirable features formed in the walls of the fuel tank.
- the present invention is defined by the following claims, and nothing in this section should be taken as a limitation on those claims.
- the embodiments herein described disclose a fuel tank system that includes a fuel system module.
- the fuel system module provides both rigid and flexible structural support using a fairly uncomplicated and economical design. The design is relatively easy to manufacture and install in the fuel tank system.
- the fuel system module may be formed to comply with the shape and structural features present in the fuel tank system.
- the fuel system module may be formed to selectively include formations that provide structural support and provisions for positioning fuel system components. Further, functional features of the fuel tank system and provisions for mounting the fuel system module within the fuel tank system may also be included.
- the fuel tank system forms a container that includes a first half and a second half.
- the first and second halves are coupled by a weld joint to form a chamber.
- the fuel system module is positioned within the chamber prior to coupling the first and second halves to minimize holes and other discontinuities in a hydrocarbon barrier.
- the hydrocarbon barrier is formed by the first and second halves, and surrounds the fuel system module.
- the fuel system module includes a pre-formed sheet.
- the pre-formed sheet is a continuous sheet formed in a predetermined shape.
- the preformed sheet may include formations to position at least one fuel system component thereon.
- the pre-formed sheet may be formed to include functional features of the fuel tank system, such as, for example, reservoirs and fuel channeling.
- the pre-formed sheet may also include formations to mount the fuel system module in one of the first half and the second half. Mounting of the fuel system module may involve coupling the fuel system module to an interior surface of either the first half or the second half of the container.
- the fuel system module utilizes the pre-formed sheet to provide both rigid and flexible structural support when subject to forces external and/or internal to the fuel tank system.
- the pre-formed sheet includes formations that exhibit rigidity when subject to forces substantially perpendicular to the surface of the pre-formed sheet.
- the pre-formed sheet includes formations that exhibit flexibility when subject to forces substantially parallel with the surface of the pre-formed sheet. Accordingly, the fuel system module may be selectively formed to provide resistance to some forces and absorption of other forces occurring within the fuel tank system.
- An interesting feature of the fuel system module is the absence of individually manufactured and assembled components and parts to achieve the functionality provided by the pre-formed sheet.
- the pre-formed sheet may also be formed contiguous with the contour of interior surfaces of the first and second halves.
- the pre-formed sheet consumes very little tank capacity while providing significant structural and operation functionality.
- due to the inherent adaptability in the formation of the pre-formed sheet accommodation of different shapes, structural support requirements and mounting requirements within the fuel system module are relatively simple.
- Another interesting feature of the fuel system module is the flexible and rigid structural support that may be designed to enhance the manufacturing process.
- structural rigidity may be included that allows an installation device, such as a robot arm to grasp, manipulate and insert the fuel system module into the fuel tank system without damage.
- damage to the hydrocarbon barrier when the fuel system module is pressed against the interior surface of the first or second halves with too much force may be avoided by providing selective flexibility.
- Yet another interesting feature of the fuel system module is the ability to create a single module in which fuel system components may be pre-configured and tested prior to installation in the fuel tank system. As such, cooperative operation of multiple components may be confirmed before the fuel system module is sealed within the container.

- the pre-formed sheet also maximizes fuel capacity to within the fuel tank and provides desirable crushing and folding characteristic during an impact.
- FIG. 1 illustrates an exploded perspective view of a fuel tank system 10 .
- the fuel tank system 10 forms a container that includes a first half 12 , a second half 14 and a fuel system module 16 .

- the sixth layer forms the other outer layer adjacent to the fifth layer and includes HDPE.
- different compositions, arrangements and quantities of layers may be used to form the thermoplastic sheet.
- the first and second halves 12 , 14 may be formed by stamping, casting, molding or any other technique for forming the desired contour, structural and functional features.
- the formation technique utilized is dependent to some extent on the materials from which the first and second halves 12 , 14 are formed. For example, metal materials are typically stamped, thermoset materials are typically cured in a mold, and thermoplastic materials may be blow molded or thermoformed using molds.
- the first and second halves 12 , 14 may be formed by twinsheet thermoforming.
- An exemplary twinsheet thermoforming technique is disclosed in a co-pending patent application entitled “HIGH VOLUME PRODUCTION OF LOW PERMEATION PLASTIC FUEL TANKS USING PARALLEL OFFSET TWINSHEET PRESSURE FORMING” Ser. No. ______ filed the same day as the present application, which is herein incorporated by reference in its entirety.
- twinsheet thermoforming allows the first and second halves 12 , 14 to be formed separately from molten thermoplastic sheets. The thermoplastic sheets are formed into the first and second halves 12 , 14 and brought together under controlled conditions to be hermetically sealed to form the container.
- the first half 12 includes a contoured top surface 20 that laterally extends to a contoured side surface 22 .
- the side surface 22 surrounds and extends various predetermined distances generally perpendicular to the top surface 20 to an edge 24 .
- the edge 24 generally forms a lip or a flange compatible with the second half 14 .
- the top surface 20 and the side surface 22 form a generally concaved shape with a first interior surface 26 .

- the access port 28 and cap 32 is not included.
- the fill neck 30 is formed in the side surface 22 to provide an entrance into the container for fluids, such as, for example, fuel.
- the fill neck 30 may be formed in the top surface 20 or the second half 14 .
- the second half 14 similarly includes a contoured top surface 34 laterally extending to a contoured side surface 36 .
- the side surface 36 extends a predetermined distance generally perpendicular to the top surface 34 to an edge 38 .
- the edge 38 is formed to create a seal with the edge 24 of the first half 12 when the first and second halves 12 , 14 are brought together.
- the top surface 34 and the side surface 36 generally form another concaved shape with a second interior surface 40 .
- the weld joint, or pinchoff is positioned to surround the periphery of the first and second halves 12 , 14 and form a hermetic seal.
- first and second interior surfaces 26 , 40 define a chamber in which fluids, such as, for example fuel may be stored.
- Each of the first and second halves 12 , 14 also include a continuous hydrocarbon barrier surrounding the chamber to deter migration of fluid out of the chamber.
- the first and second halves 12 , 14 form a low permeation plastic fuel tank.
- the fuel system module 16 is positioned within the chamber defined by the first and second halves 12 , 14 .
- the fuel system module 16 provides a single module encompassing whatever functionality is selected for inclusion within the fuel tank system 10 . Accordingly, the selected functionality may be relatively quickly and easily installed during manufacture of the fuel tank system 10 .
- the fuel system module 16 may comprise functionality requiring cooperative operation of a number of different components. By building the functionality as part of the fuel system module 16 , cooperative operation of the components may be verified. Verification may be performed prior to installation of the fuel system module 16 . Further, a low hydrocarbon emission fuel tank may be created since the fuel system module 16 is completely enclosed within the hydrocarbon barrier provided by the first and second halves 12 , 14 .
- the embodiment of the fuel system module 16 illustrated in FIG. 1 includes at least one fuel system component 44 and a pre-formed sheet 46 .
- the fuel system component 44 may be a valve, a hose, an electric conductor, a pump, a filter, a sensor or any other fuel system related mechanism and/or feature.
- a plurality of fuel system components 44 are depicted. Namely, FIG. 1 includes a fuel level vent valve (FLW) 44 a, a rollover valve 44 b, and a plurality of hoses 44 c for transporting fuel and vapors. In other embodiments, additional or fewer fuel system components 44 may be included.
- the fuel system components 44 are positioned contiguous with the pre-formed sheet 46 .
- the pre-formed sheet 46 may be any sheet fashioned in a predetermined shape forming a continuous layer between the first and second halves 12 , 14 .
- the term “sheet” refers to materials with opposing surfaces in which the thickness of the materials between the opposing surfaces are thin in comparison to the length and/or the width of the opposing surfaces.
- the pre-formed sheet 46 may be relatively flat or may include contours, ridges, ribs, flanges, fins, folds, cavities, grooves, notches, troughs, passageways, holes or any other formations formable within a sheet.
- the pre-formed sheet 46 may be formed from polymers such as for example, thermoplastic material, thermoset material or a combination of both.
- the pre-formed sheet 46 may be formed of metal or any other semi-rigid material capable of being fashioned into a sheet with a predetermined functional shape.
- the pre-formed sheet 46 provides both a rigid structure and a flexible structure as a function of the shape of the pre-formed sheet 46 .
- a sheet is inherently relatively stiff when subject to forces acting in directions substantially perpendicular to the opposing surfaces, and relatively flexible when subject to forces acting in directions substantially parallel to the opposing surfaces.
- substantially parallel refers to forces with a larger shear stress component and a smaller normal stress component acting on the opposing surfaces of the sheet.
- substantially perpendicular refers to those forces with a larger normal stress component and a smaller shear stress component acting on the opposing surfaces of the sheet.
- references herein to “surfaces” of the pre-formed sheet 46 refer to the orientation of the plane generally occupied by the extending pre-formed sheet 46 and not the individual formations thereon.
- exemplary external forces include vibration, impact forces and vacuum/pressure created in the fuel tank system 10 .
- exemplary internal forces include shrinkage and swelling between structures, transient thermal imbalances due to uneven heating and cooling and dynamic loading caused by lateral movement of the fuel system components 44 or fuel within the fuel tank system 10 .
- the pre-formed sheet 46 may include formations that allow the application of pressure to urge the fuel system module 16 into contact with the first interior surface 26 or the second interior surface 40 .
- Rigidity designed into the pre-formed sheet 46 allows manipulation by, for example, a robot arm without creating undesirable and potentially damaging deformation and/or stress of the fuel system module 16 .
- Design of the preformed sheet 46 may also include flexibility to alleviate any excessive pressure that may otherwise cause damaging stress to the hydrocarbon barrier when the fuel system module 16 is urged into contact. Accordingly, the fuel system module 16 absorbs undesirable stresses while at the same time providing rigid resistance to other stresses to maintain the integrity and functionality of the fuel tank system 10 .
- the pre-formed sheet 46 is formed from thermoplastic material.
- the thermoplastic material may be formed by blow molding, thermosetting, and/or any other technique for forming thermoplastic.
- the thermoplastic material is a single continuous thermoplastic sheet.
- the thermoplastic material may include at least two separately formed thermoplastic sheets that are welded, or otherwise coupled together to form a continuous sheet.
- the pre-formed sheet 46 may also include at least one functional feature 48 formed within the pre-formed sheet 46 .
- Exemplary functional features 48 include a liquid reservoir, a liquid channel, a baffle, provisions for fuel system components 44 , provisions for coupling the pre-formed sheet 46 to one of the first and second halves 12 , 14 , a structural support and/or any other functional features pertaining to fuel systems and fuel system operation.
- the pre-formed sheet 46 may also include apertures. The apertures may be located to allow the flow of fuel and air through the pre-formed sheet 46 , as well as avoiding undesirable pooling of fuel and creation of air pockets.
- the functional features 48 within the pre-formed sheet 46 may include formations to provide stiffness as well as flexibility when subject to internal and external forces. For example, through selective formation of the functional features 48 , forces applied substantially perpendicular to surfaces of the pre-formed sheet 46 may be presented with stiffness. Similarly, forces applied substantially parallel with surfaces of the pre-formed sheet 46 may be presented with flexibility. In addition, functional features 48 may be formed to allow the pre-formed sheet 46 to selectively react with flexibility and/or stiffness to non-parallel and/or non-perpendicular shearing forces, as well as moment loading, within the fuel tank system 10 .
- the functional features 48 include a first feature 48 a, a second feature 48 b and a third feature 48 c.
- the first feature 48 a includes a number of functional characteristics.
- One characteristic is structural and is provided by a cylindrical, hollow, generally barrel shaped first housing 50 formed in the preformed sheet 46 .
- the formation forming the first housing 50 may be generally shaped as, for example, square, rectangular, spherical, conical, elliptical or any other shape.
- the first housing 50 may longitudinally extend to be perpendicular and adjacent to both the first interior surface 26 and the second interior surface 40 when the first and second halves 12 , 14 are brought together.
- the nature of the formation of the first housing 50 allows the pre-formed sheet 46 to provide rigid support when the first and second halves 12 , 14 are subject to compressive forces.
- Exemplary compressive forces include forces induced by vacuum, bending and warping that may cause the first and second halves 12 , 14 to move closer together.
- the first housing 50 does not provide a fixed rigid connection between the first and second surfaces 26 , 40 .
- the first housing 50 may be formed to be adjacent only the first or the second halves 12 , 14 and provide no rigid support.
- the support may be formed to be rigid and/or flexible.
- the preformed sheet 46 may flex to allow the fuel system component 44 to move substantially parallel to surfaces of the pre-formed sheet 46 while remaining rigid against movement perpendicular to surfaces of the pre-formed sheet 46 .
- a fuel system component 44 such as, for example, a fuel pump may be positioned within the first housing 50 . Installation of the fuel system component 44 may be performed by removing the cap 32 and lowering the fuel system component 44 through the access port 28 . Alternatively, the fuel system component 44 may be installed before the first and second halves 12 , 14 are sealed together. The fuel system component 44 may be held within the first housing 50 by friction fit, screw connection, snap-fit, welding, gluing or any other mechanism for coupling the fuel system component 44 to the first housing 50 .
- FIG. 2 illustrates a top view of a portion of the fuel system module 16 with the fuel system components 44 removed and portions of the pre-formed sheet 46 cross-sectioned.
- Another characteristic provided by the illustrated embodiment of the first feature 48 a is a reservoir formed by the hollow within the first housing 50 that includes a swirl pot 52 .
- the swirl pot 52 is formed in the pre-formed sheet 46 to provide a channel for flow of liquid through an aperture 54 in the first housing 50 .
- the swirl pot 52 operates in a well-known manner to retain fuel within the first housing 50 .
- the second feature 48 b of this embodiment similarly includes a cylindrical, hollow, generally barrel shaped second housing 56 formed in the pre-formed sheet 46 .
- the second housing 56 similarly includes provision to accept at least one fuel system component 44 such as for example, the FLW 44 a and/or the roll over valve 44 b.
- the second housing 56 may provide rigidity and/or flexibility within the pre-formed sheet 46 similar to the first housing 50 .
- the formation of the second feature 48 b may be generally shaped as, for example, square, rectangular, spherical, conical, elliptical or any other shape.
- the first and second housings 50 , 56 may be used as temporary positioning devices for the fuel system components 44 .
- a fuel system component 44 may be temporarily positioned in one of the first or second housings 50 or 56 .
- the fuel system component 44 is maintained in a predetermined position and coupled to the first or second interior surfaces 26 or 40 .
- the fuel system components 44 may be temporarily positioned by other formations within the pre-formed sheet 46 .
- Coupling occurs when the first and second halves 12 , 14 are brought together and the fuel system component 44 is pressed against the first or second interior surfaces 26 or 40 by the first or second housings 50 or 56 .
- the first and second housings 50 , 56 may be formed in the pre-formed sheet 46 to provide sufficient flexibility and rigidity (compressive resistance) to promote proper coupling of the fuel system component 44 . Sufficient flexibility may, for example, prevent the fuel system component 44 from being embedded to an undesirable depth in the first or second interior surfaces 26 or 40 .
- the third feature 48 c of the illustrated embodiment comprises a plurality of ribs, or channels selectively formed in the pre-formed sheet 46 for enhancement of the structural integrity of the fuel system module 16 .
- the ribs may be selectively formed to enhance flexibility as well as rigidity.
- Other features may also be formed in the preformed sheet 16 , such as, for example, apertures to provide a baffling function for slosh abatement and noise control as well as improved durability.
- Other exemplary formations such as, shelves, grooves, notches or folds provided to maintain the position of the hoses 44 c or any other functional features 48 may be formed in the pre-formed sheet 46 .
- the pre-formed sheet 46 as a whole may serve as a condensing surface and an anti-turbulence system to reduce fuel-air mixing and resultant fuel vapor generation.
- the fuel system module 16 may be positioned in either the first half 12 or the second half 14 during the manufacturing process. In one embodiment, the fuel system module 16 is fixedly coupled to either the first interior surface 26 or the second interior surface 40 .
- the pre-formed sheet 46 may include formations to provide rigid and/or flexible coupling. The formations for coupling may cooperatively operate with other formations in the pre-formed sheet 46 similarly providing rigidity and or flexibility. Exemplary formations for coupling may include areas of the pre-formed sheet 46 formed to be contiguous with the first interior surface 26 or the second interior surface 40 .
- the formations may be fixedly coupled with the contiguous first or second interior surface 26 or 40 by, for example, welding, gluing or any other coupling mechanism that does not compromise the hydrocarbon barrier.
- some form of adapter mechanism may be formed from the pre-formed sheet 46 or provided as a separate device to facilitate coupling.
- An exemplary adapter mechanism is disclosed in a co-pending patent application entitled “ADAPTER FOR WELDING OBJECTS TO PLASTIC” Ser. No. ______ filed the same day as the present application, which is herein incorporated by reference in its entirety.
- the fuel system module 16 is not fixedly coupled to either the first half 12 or the second half 14 . Instead, geometric interferences between the contours of the first half 12 , the second half 14 and formations in the pre-formed sheet 46 hold the fuel system module 16 in position. In this embodiment, the fuel system module 16 is mounted in, and supported by, one of the first half 12 and the second half 14 .

Abstract
A low permeation fuel tank formed with a first half and a second half includes a hydrocarbon barrier and a fuel system module. The hydrocarbon barrier reduces the emission of hydrocarbons from the fuel tank. Minimization of discontinuities in the hydrocarbon barrier is achieved by positioning the fuel system module within the fuel tank. The fuel system module includes a preformed sheet to provide flexible and rigid support to the fuel tank. In addition, the fuel system module may include fuel system components, structural enhancements of the fuel tank and/or functional features of the fuel tank to minimize production of holes or other discontinuities in the hydrocarbon barrier.
Description
- This application claims the benefit under35 U.S.C. §119(e) of Provisional U.S. patent application Ser. No. 60/224,487 filed on Aug. 11, 2000.
- 1. Field of the Invention
- This invention relates to fuel tanks, and more particularly to a low permeation fuel tank that includes internally mounted components.
- 2. Description of the Related Art
- Fuel tanks made of plastic or metal are well known for providing a reservoir of fuel for engines and other fuel consuming devices in land, water and air vehicles. A hydrocarbon barrier is typically included in fuel tanks to prevent passage of fuel and associated vapors therethrough. Additional components are usually added to the fuel tank to create a fuel system. The components may include valves, hoses, pumps, level sensors, structural supports, etc. Typically, some of these components are installed inside the fuel tank by cutting service holes in the tank. In addition, some of the components are installed outside the tank requiring additional holes, grooves and/or recesses.
- Recent changes in government regulations have reduced the amount of allowable fuel vapor emissions from fuel tanks. One way to reduce allowable fuel vapor emissions is through minimization of breaches in the hydrocarbon barrier. Reduction in the number of holes in the fuel tank through internalization of fuel system components minimizes breaches. One way to internalize fuel system components is to insert the components during manufacture of the tank.
- Some fuel tanks are manufactured with a structure inside the tank. The structure provides for internalized mounting of fuel system components. In addition, the structure includes rigid columns that are rigidly connected with opposite walls of the fuel tank to maintain the structure in position. The columns are located to generally define the perimeter of the structure. In addition to supporting the remaining structure, the columns also provide local structural support for the fuel tank. The remaining structure is created with rigid members. Some of the rigid members include compliant joints to allow the otherwise rigid structure to distort in response to external forces. Such a structure is described in U.S. Pat. No. 6,138,859 to Aulph et al.
- One problem with prior art structures is the significant cost and complexity that is added to the tank to achieve structural support and the ability to distort in the presence of external forces. Manufacturing fuel tanks with prior art structures involves forming each of the individual members/columns, coupling the members and columns in a predetermined pattern and then coupling the resulting structure with a fuel tank. The quantity and placement of the members may vary significantly among different structures depending on the design of the fuel tank. In addition, coupling the columns with opposite walls of the fuel tank may be difficult to perform and/or verify. Aside from the significant design and manufacturing requirements to create and install the structure, accommodation of the structure may adversely affect the overall design and functionality of the fuel tank.
- For example, the use of columns to support the structure may require placement of columns where no structural support of the fuel tank is needed. In addition, columns may provide stiffness that hinders desirable crushing and/or folding characteristics of the fuel tank during an impact, such as in a crash situation. Further, shearing and moment forces applied to only a portion of the tank, such as, for example, in a crash situation, may be transferred to another portion of the tank by the rigid nature of the columns causing additional damage. Finally, column placement required to support the structure may interfere with ribbing and other desirable features formed in the walls of the fuel tank.
- The present invention is defined by the following claims, and nothing in this section should be taken as a limitation on those claims. By way of introduction, the embodiments herein described disclose a fuel tank system that includes a fuel system module. The fuel system module provides both rigid and flexible structural support using a fairly uncomplicated and economical design. The design is relatively easy to manufacture and install in the fuel tank system. The fuel system module may be formed to comply with the shape and structural features present in the fuel tank system. In addition, the fuel system module may be formed to selectively include formations that provide structural support and provisions for positioning fuel system components. Further, functional features of the fuel tank system and provisions for mounting the fuel system module within the fuel tank system may also be included.
- The fuel tank system forms a container that includes a first half and a second half. The first and second halves are coupled by a weld joint to form a chamber. The fuel system module is positioned within the chamber prior to coupling the first and second halves to minimize holes and other discontinuities in a hydrocarbon barrier. The hydrocarbon barrier is formed by the first and second halves, and surrounds the fuel system module.
- The fuel system module includes a pre-formed sheet. The pre-formed sheet is a continuous sheet formed in a predetermined shape. The preformed sheet may include formations to position at least one fuel system component thereon. In addition, the pre-formed sheet may be formed to include functional features of the fuel tank system, such as, for example, reservoirs and fuel channeling. The pre-formed sheet may also include formations to mount the fuel system module in one of the first half and the second half. Mounting of the fuel system module may involve coupling the fuel system module to an interior surface of either the first half or the second half of the container.
- The fuel system module utilizes the pre-formed sheet to provide both rigid and flexible structural support when subject to forces external and/or internal to the fuel tank system. The pre-formed sheet includes formations that exhibit rigidity when subject to forces substantially perpendicular to the surface of the pre-formed sheet. In addition, the pre-formed sheet includes formations that exhibit flexibility when subject to forces substantially parallel with the surface of the pre-formed sheet. Accordingly, the fuel system module may be selectively formed to provide resistance to some forces and absorption of other forces occurring within the fuel tank system.
- An interesting feature of the fuel system module is the absence of individually manufactured and assembled components and parts to achieve the functionality provided by the pre-formed sheet. The pre-formed sheet may also be formed contiguous with the contour of interior surfaces of the first and second halves. In addition, the pre-formed sheet consumes very little tank capacity while providing significant structural and operation functionality. Further, due to the inherent adaptability in the formation of the pre-formed sheet, accommodation of different shapes, structural support requirements and mounting requirements within the fuel system module are relatively simple.
- Another interesting feature of the fuel system module is the flexible and rigid structural support that may be designed to enhance the manufacturing process. For example, structural rigidity may be included that allows an installation device, such as a robot arm to grasp, manipulate and insert the fuel system module into the fuel tank system without damage. In addition, damage to the hydrocarbon barrier when the fuel system module is pressed against the interior surface of the first or second halves with too much force may be avoided by providing selective flexibility.
- Yet another interesting feature of the fuel system module is the ability to create a single module in which fuel system components may be pre-configured and tested prior to installation in the fuel tank system. As such, cooperative operation of multiple components may be confirmed before the fuel system module is sealed within the container.

- Embodiments of a fuel system module for use in a fuel tank system are disclosed. The fuel system module comprises at least one pre-formed sheet that is shaped for insertion as a layer between the two halves of a fuel tank during the manufacturing process. Fuel system components and functional features of the fuel system may be included as part of the fuel system module. The fuel system module is formed to provide structural rigidity for supporting the fuel system components and functional features while also providing flexibility to alleviate undesirable stresses that may develop. In addition, the fuel system module may be pre-formed in any shape compatible with the structural features and/or contours of the fuel tank. Support of the fuel system module within one of the two halves of the fuel tank is provided by formations in the pre-formed sheet. The pre-formed sheet also maximizes fuel capacity to within the fuel tank and provides desirable crushing and folding characteristic during an impact.
- FIG. 1 illustrates an exploded perspective view of a
fuel tank system 10. Thefuel tank system 10 forms a container that includes afirst half 12, asecond half 14 and afuel system module 16. In the illustrated embodiment, thefuel tank system 10 is formed as a saddle type fuel tank. In other embodiments, thefuel tank system 10 may be formed in any other shape forming a fuel tank. - The
first half 12 forms the top half and thesecond half 14 forms the bottom half of the fuel tank in the illustrated embodiment. In other embodiments, the first and second halves may be left and right side halves, front and backside halves or any other formation of two halves forming a fuel tank. In still other embodiments, the twohalves halves second halves second half 12 may form the bottom and sides of the container and thesecond half 14 may form a top cover. - The first and
second halves - In one embodiment, the thermoplastic materials are in the form of thermoplastic sheets with six layers. The first layer is an outer layer that includes high-density polyethylene (HDPE) and carbon black. The second layer is an inner layer positioned adjacent to the first layer and includes reground thermoplastic sheet material. A third layer positioned adjacent the second layer is also an inner layer and includes adhesive polymer. Positioned adjacent the third layer is a fourth layer that includes ethylene vinyl alcohol (EVOH). The EVOH layer of this embodiment provides a hydrocarbon barrier for reduction of the emission of hydrocarbons permeating through the thermoplastic sheet. A fifth layer is positioned adjacent the fourth layer and includes adhesive polymer. The sixth layer forms the other outer layer adjacent to the fifth layer and includes HDPE. In other embodiments, different compositions, arrangements and quantities of layers may be used to form the thermoplastic sheet.
- The first and
second halves second halves - In one embodiment, where thermoplastic sheets are used, the first and
second halves second halves second halves - In the illustrated embodiment, the
first half 12 includes a contouredtop surface 20 that laterally extends to a contouredside surface 22. Theside surface 22 surrounds and extends various predetermined distances generally perpendicular to thetop surface 20 to anedge 24. Theedge 24 generally forms a lip or a flange compatible with thesecond half 14. Thetop surface 20 and theside surface 22 form a generally concaved shape with a firstinterior surface 26. - The
first half 12 of this embodiment also includes at least oneaccess port 28 and afill neck 30. Theaccess port 28 is a formation within the contouredtop surface 20. Theaccess port 28 includes provisions for creating an aperture to access the interior of the first andsecond halves access port 28 may also be formed to couple acap 32 to thefirst half 12 by, for example, snap fit, threaded connection, snap lock or some other coupling mechanism. In other embodiments, theaccess port 28 andcap 32 is not included. Thefill neck 30 is formed in theside surface 22 to provide an entrance into the container for fluids, such as, for example, fuel. In other embodiments, thefill neck 30 may be formed in thetop surface 20 or thesecond half 14. - The
second half 14 similarly includes a contouredtop surface 34 laterally extending to a contouredside surface 36. Theside surface 36 extends a predetermined distance generally perpendicular to thetop surface 34 to anedge 38. Theedge 38 is formed to create a seal with theedge 24 of thefirst half 12 when the first andsecond halves top surface 34 and theside surface 36 generally form another concaved shape with a secondinterior surface 40. When the first andsecond halves edges second halves - Once sealed, the first and second
interior surfaces second halves second halves - The
fuel system module 16 is positioned within the chamber defined by the first andsecond halves fuel system module 16 provides a single module encompassing whatever functionality is selected for inclusion within thefuel tank system 10. Accordingly, the selected functionality may be relatively quickly and easily installed during manufacture of thefuel tank system 10. - In addition, the
fuel system module 16 may comprise functionality requiring cooperative operation of a number of different components. By building the functionality as part of thefuel system module 16, cooperative operation of the components may be verified. Verification may be performed prior to installation of thefuel system module 16. Further, a low hydrocarbon emission fuel tank may be created since thefuel system module 16 is completely enclosed within the hydrocarbon barrier provided by the first andsecond halves - The embodiment of the
fuel system module 16 illustrated in FIG. 1 includes at least onefuel system component 44 and apre-formed sheet 46. Thefuel system component 44 may be a valve, a hose, an electric conductor, a pump, a filter, a sensor or any other fuel system related mechanism and/or feature. In the illustrated embodiment, a plurality offuel system components 44 are depicted. Namely, FIG. 1 includes a fuel level vent valve (FLW) 44 a, arollover valve 44 b, and a plurality of hoses 44 c for transporting fuel and vapors. In other embodiments, additional or fewerfuel system components 44 may be included. Thefuel system components 44 are positioned contiguous with thepre-formed sheet 46. - The
pre-formed sheet 46 may be any sheet fashioned in a predetermined shape forming a continuous layer between the first andsecond halves pre-formed sheet 46 may be relatively flat or may include contours, ridges, ribs, flanges, fins, folds, cavities, grooves, notches, troughs, passageways, holes or any other formations formable within a sheet. Thepre-formed sheet 46 may be formed from polymers such as for example, thermoplastic material, thermoset material or a combination of both. In addition thepre-formed sheet 46 may be formed of metal or any other semi-rigid material capable of being fashioned into a sheet with a predetermined functional shape. - In the presently preferred embodiments, the
pre-formed sheet 46 provides both a rigid structure and a flexible structure as a function of the shape of thepre-formed sheet 46. A sheet is inherently relatively stiff when subject to forces acting in directions substantially perpendicular to the opposing surfaces, and relatively flexible when subject to forces acting in directions substantially parallel to the opposing surfaces. - As used herein, “substantially parallel” refers to forces with a larger shear stress component and a smaller normal stress component acting on the opposing surfaces of the sheet. Similarly, “substantially perpendicular” refers to those forces with a larger normal stress component and a smaller shear stress component acting on the opposing surfaces of the sheet. In addition, references herein to “surfaces” of the
pre-formed sheet 46 refer to the orientation of the plane generally occupied by the extendingpre-formed sheet 46 and not the individual formations thereon. - By strategically shaping formations within the
pre-formed sheet 46, rigidity when exposed to some forces, and flexibility when exposed to other forces may be achieved. The formations may also be designed and shaped with pre-determined failure levels to provide predictable crushing and folding characteristics when subject to excessive and/or undesirable forces. Forces thepre-formed sheet 46 may be subject to include external forces imparted on thefuel tank system 10 as well as internally created forces. Exemplary external forces include vibration, impact forces and vacuum/pressure created in thefuel tank system 10. On the other hand, exemplary internal forces include shrinkage and swelling between structures, transient thermal imbalances due to uneven heating and cooling and dynamic loading caused by lateral movement of thefuel system components 44 or fuel within thefuel tank system 10. - For example, the
pre-formed sheet 46 may include formations that allow the application of pressure to urge thefuel system module 16 into contact with the firstinterior surface 26 or the secondinterior surface 40. Rigidity designed into thepre-formed sheet 46 allows manipulation by, for example, a robot arm without creating undesirable and potentially damaging deformation and/or stress of thefuel system module 16. Design of the preformedsheet 46 may also include flexibility to alleviate any excessive pressure that may otherwise cause damaging stress to the hydrocarbon barrier when thefuel system module 16 is urged into contact. Accordingly, thefuel system module 16 absorbs undesirable stresses while at the same time providing rigid resistance to other stresses to maintain the integrity and functionality of thefuel tank system 10. - In one embodiment, the
pre-formed sheet 46 is formed from thermoplastic material. The thermoplastic material may be formed by blow molding, thermosetting, and/or any other technique for forming thermoplastic. In one embodiment, the thermoplastic material is a single continuous thermoplastic sheet. In other embodiments, the thermoplastic material may include at least two separately formed thermoplastic sheets that are welded, or otherwise coupled together to form a continuous sheet. - The
pre-formed sheet 46 may also include at least one functional feature 48 formed within thepre-formed sheet 46. Exemplary functional features 48 include a liquid reservoir, a liquid channel, a baffle, provisions forfuel system components 44, provisions for coupling thepre-formed sheet 46 to one of the first andsecond halves pre-formed sheet 46 may also include apertures. The apertures may be located to allow the flow of fuel and air through thepre-formed sheet 46, as well as avoiding undesirable pooling of fuel and creation of air pockets. - In addition, the functional features48 within the
pre-formed sheet 46 may include formations to provide stiffness as well as flexibility when subject to internal and external forces. For example, through selective formation of the functional features 48, forces applied substantially perpendicular to surfaces of thepre-formed sheet 46 may be presented with stiffness. Similarly, forces applied substantially parallel with surfaces of thepre-formed sheet 46 may be presented with flexibility. In addition, functional features 48 may be formed to allow thepre-formed sheet 46 to selectively react with flexibility and/or stiffness to non-parallel and/or non-perpendicular shearing forces, as well as moment loading, within thefuel tank system 10. - In the illustrated embodiment, the functional features48 include a
first feature 48 a, asecond feature 48 b and athird feature 48 c. Thefirst feature 48 a includes a number of functional characteristics. One characteristic is structural and is provided by a cylindrical, hollow, generally barrel shapedfirst housing 50 formed in the preformedsheet 46. In other embodiments, the formation forming thefirst housing 50 may be generally shaped as, for example, square, rectangular, spherical, conical, elliptical or any other shape. - The
first housing 50 may longitudinally extend to be perpendicular and adjacent to both the firstinterior surface 26 and the secondinterior surface 40 when the first andsecond halves first housing 50 allows thepre-formed sheet 46 to provide rigid support when the first andsecond halves second halves first housing 50 does not provide a fixed rigid connection between the first andsecond surfaces first housing 50 may be formed to be adjacent only the first or thesecond halves - Another characteristic provided by the
first housing 50 is support forfuel system components 44 inserted into the hollow within thefirst housing 50. The support may be formed to be rigid and/or flexible. For example, the preformedsheet 46 may flex to allow thefuel system component 44 to move substantially parallel to surfaces of thepre-formed sheet 46 while remaining rigid against movement perpendicular to surfaces of thepre-formed sheet 46. - In the illustrated embodiment, a
fuel system component 44, such as, for example, a fuel pump may be positioned within thefirst housing 50. Installation of thefuel system component 44 may be performed by removing thecap 32 and lowering thefuel system component 44 through theaccess port 28. Alternatively, thefuel system component 44 may be installed before the first andsecond halves fuel system component 44 may be held within thefirst housing 50 by friction fit, screw connection, snap-fit, welding, gluing or any other mechanism for coupling thefuel system component 44 to thefirst housing 50. - FIG. 2 illustrates a top view of a portion of the
fuel system module 16 with thefuel system components 44 removed and portions of thepre-formed sheet 46 cross-sectioned. Another characteristic provided by the illustrated embodiment of thefirst feature 48 a is a reservoir formed by the hollow within thefirst housing 50 that includes aswirl pot 52. Theswirl pot 52 is formed in thepre-formed sheet 46 to provide a channel for flow of liquid through anaperture 54 in thefirst housing 50. Theswirl pot 52 operates in a well-known manner to retain fuel within thefirst housing 50. - Referring now to FIGS. 1 and 2, the
second feature 48 b of this embodiment similarly includes a cylindrical, hollow, generally barrel shapedsecond housing 56 formed in thepre-formed sheet 46. Thesecond housing 56 similarly includes provision to accept at least onefuel system component 44 such as for example, theFLW 44 a and/or the roll overvalve 44 b. In addition, thesecond housing 56 may provide rigidity and/or flexibility within thepre-formed sheet 46 similar to thefirst housing 50. In other embodiments, the formation of thesecond feature 48 b may be generally shaped as, for example, square, rectangular, spherical, conical, elliptical or any other shape. - In another embodiment, the first and
second housings fuel system components 44. During manufacture, afuel system component 44 may be temporarily positioned in one of the first orsecond housings fuel system component 44 is maintained in a predetermined position and coupled to the first or secondinterior surfaces fuel system components 44 may be temporarily positioned by other formations within thepre-formed sheet 46. - Coupling occurs when the first and
second halves fuel system component 44 is pressed against the first or secondinterior surfaces second housings second housings pre-formed sheet 46 to provide sufficient flexibility and rigidity (compressive resistance) to promote proper coupling of thefuel system component 44. Sufficient flexibility may, for example, prevent thefuel system component 44 from being embedded to an undesirable depth in the first or secondinterior surfaces - The
third feature 48 c of the illustrated embodiment comprises a plurality of ribs, or channels selectively formed in thepre-formed sheet 46 for enhancement of the structural integrity of thefuel system module 16. The ribs may be selectively formed to enhance flexibility as well as rigidity. Other features may also be formed in the preformedsheet 16, such as, for example, apertures to provide a baffling function for slosh abatement and noise control as well as improved durability. Other exemplary formations such as, shelves, grooves, notches or folds provided to maintain the position of the hoses 44 c or any other functional features 48 may be formed in thepre-formed sheet 46. In addition, thepre-formed sheet 46 as a whole may serve as a condensing surface and an anti-turbulence system to reduce fuel-air mixing and resultant fuel vapor generation. - The
fuel system module 16 may be positioned in either thefirst half 12 or thesecond half 14 during the manufacturing process. In one embodiment, thefuel system module 16 is fixedly coupled to either the firstinterior surface 26 or the secondinterior surface 40. In this embodiment, thepre-formed sheet 46 may include formations to provide rigid and/or flexible coupling. The formations for coupling may cooperatively operate with other formations in thepre-formed sheet 46 similarly providing rigidity and or flexibility. Exemplary formations for coupling may include areas of thepre-formed sheet 46 formed to be contiguous with the firstinterior surface 26 or the secondinterior surface 40. - The formations may be fixedly coupled with the contiguous first or second
