A filling pipe arrangement for filling an automobile fluid tank with fluid, especially aqueous urea solution, with a passage passing through a predetermined passageway along the filling pipe arrangement, wherein the passage extends from an inserting mouth to a discharge opening, wherein an inserting end section of the passage comprising the inserting mouth is designed to hold at least temporarily an output end section of a delivery device, such as a spigot, a Kruse bottle, or the like, wherein the passage comprises, at a distance from the inserting mouth, a conducting section designed to lead fluid introduced into the filling pipe arrangement through the filling pipe arrangement, wherein the filling pipe arrangement comprises a magnetic arrangement whose magnetic field reaches into the passage in one section of the passageway, the magnetic arrangement is received in the filling pipe arrangement so that it is movable along the passageway.

An object is to suppress excessive insertion of a fueling nozzle during fueling. A nozzle guide configured to form a nozzle guide path that guides a fueling nozzle is placed inside of a filler neck main body configured to include a fuel passage that introduces a fuel supplied from the fueling nozzle toward a fuel tank. This nozzle guide comprises a first projection for nozzle restriction provided on a nozzle guide end opening portion at an end of the nozzle guide path along a nozzle guide direction and protruded from an end opening circumferential wall of the nozzle guide end opening portion to narrow at least part of a diameter of the nozzle guide path; and a second projection for nozzle restriction provided on a downstream side of the first projection along the nozzle guide direction and protruded from the end opening circumferential wall to narrow at least part of the diameter of the nozzle guide path.

A fuel lid opener has: a case that is mounted to an outer peripheral surface of a side wall of a lid box at which a fuel lid is pivotally supported so as to be able to open and close; a lifter that is supported at the case so as to be able to rotate around an axis that runs along a plate surface direction of the fuel lid that is in a closed state, and that has an arm portion that extends in a rotation radial direction within the lid box, and a distal end portion of the arm portion engages with the fuel lid that is in the closed state from a reverse surface side; and a heart cam mechanism that is provided within the case, and that, each time the arm portion of the lifter is push-operated in one direction around the axis via the fuel lid, causes the lifter to alternately repeat rotation in one direction and in another direction around the axis, and that pushes the fuel lid open due to rotation of the lifter in the another direction.

A variable inlet device for a vehicle includes a first pipe and a second pipe arranged in parallel to each other, and a variable injection pipe configured to allow an exit thereof to be selectively connected to an entrance of the first pipe or an entrance of the second pipe by a rotation movement and a back and forth movement.

A channel forming member is attached to a filler neck on a nozzle insertion side where a fueling nozzle is to be inserted. The channel forming member includes a barrier section that forms an insertion flow path section for the fueling nozzle in the fuel flow path on the nozzle insertion side, while forming an annular channel surrounding the insertion flow path section so as to separate the channel from the insertion flow path section. The channel forming member further includes the following provided to the barrier section: an atmosphere communication hole for making the channel communicate with the atmosphere; a flow path communication hole for making the channel communicate with an insertion end flow path section downstream from the insertion flow path section; and a valve mechanism that prevents passage of the atmosphere through the channel in a fueling period. This contributes to reduction in introduction of the atmosphere into the fuel flow path through the channel in a fueling period.

A filler pipe is attached to a retainer that holds a fuel nozzle holder. The retainer includes: a first attaching portion attached to an inlet portion of the filler pipe; a holding portion having an engaging hole; and an opening positioned at a first end of the retainer, which is closer to a longitudinal center of the filler pipe than a second end is. The fuel nozzle holder includes: a second attaching portion and including an engaging piece that engages the engaging hole; and a main body extending from the second attaching portion toward the longitudinal center of the filler pipe. The engaging piece is surrounded at three sides by a groove having a U-shape. The engaging piece is connected to the second attaching portion on the main body-side. The holding portion extends toward the longitudinal center of the filler pipe to cover the groove.

A polyamide composite resin composition for a fuel filler pipe includes 41 to 77% by weight of polyamide 6, 5 to 15% by weight of m-xylenediamine (MXD)-based modified nylon, 14 to 30% by weight of a maleic anhydride-grafted ethylene-octene copolymer, a maleic anhydride-grafted ethylene-propylene-diene monomer, or a mixture thereof, and 3 to 10% by weight of mixed clay.

An object is to provide a fuel supply system having a filler neck formed easily with high accuracy. A fuel supply system is configured to supply fuel ejected from a fuel nozzle to a fuel tank. The fuel supply system comprises a filler neck including a resin filler neck body and a metal retainer. The filler neck body is formed in a tubular shape and has an opening end arranged to form an opening which the fuel nozzle is inserted through. The retainer is placed to cover at least part of the opening end of the filler neck body and is joined with the filler neck body in at least part of the filler neck body by thermal welding.

A capless refueling port attached to a fuel tank of a vehicle is presented. In one example, the capless refueling port includes a main opening, an articulating unitary plug mounted within a nozzle chamber of the fuel port, and a drain tube. The articulating plug is configured to partially or fully close an inlet of the drain tube connected to the fuel port during refueling; the articulating plug is further adjusted to open after refueling, allowing the fuel port to dissipate any residual pressure in the nozzle chamber to the atmosphere.

A fuel cap bib for protecting aluminum fuel tanks from being scratched by hanging fuel caps during fueling is provided. The fuel cap bib is a sheet of petroleum-based fluid resistant, elastic material having a through hole dimensioned and adapted to deformed over an engaged fuel cap and yet snugly bias about the circumferential flanges the fuel cap engages. The fuel cap bib provides a protective surface between the disengaged, hanging fuel cap and the aluminum fuel tank.
