An opening device for a urea water inlet may include a first body configured to be provided on an external side of an inlet of a urea filler neck; a second body disposed at an upper end portion of the first body with a ventilation gap between the first body and the second body, and provided with an internal space to be disposed above the inlet; a cover disposed at an upper end portion of the second body, and configured to receive a force to open the internal space of the second body; an opener provided in the second body, and configured to hold the cover at the upper portion of the second body when the cover is configured to close the internal space, and to release holding of the cover when being pressed toward an interior of the second body; and a membrane disposed between the first body and the second body to pass only air therethrough while covering the ventilation gap.

A retainer that holds a fuel nozzle holder is mounted to a filler pipe. The retainer includes: a first attaching portion mounted at the filler pipe; an opening located at a first end of the retainer, which is closer to a center of the filler pipe than a second end; and a holding portion having engaging holes. The fuel nozzle holder includes: a second attaching portion having a cylindrical shape and including two engaging pieces engaged in the engaging holes and located on opposite sides in a circumference of the second attaching portion. The engaging pieces are each surrounded by a groove at three sides and joined to the second attaching portion on one, and the two engaging pieces are different from each other in terms of a maximum value of a length in a circumferential direction of the second attaching portion.

A capless filler pipe closure is provided for a tank filler pipe. The capless closure permits a fuel pump nozzle to be inserted into the tank filler pipe without first removing a fuel cap from the outer end of the tank filler pipe.

A fuel tank device for a vehicle that includes a plastic fuel tank having a conductive outer layer, a plastic filler pipe for filling the fuel tank, at least one metallic component, and an electrical connector to connect the metallic component to the conductive outer layer of the filler pipe. The metallic component is grounded via the electrical connector and the conductive outer layer of the filler pipe.

A vehicle mounted fuel filler pocket and hingedly attachable door assembly, having a housing with an upper rim edge defining a pocket shaped body to which is communicated a fuel filler tube. A door overlays the upper rim edge in a closed position. A hinge bracket secures to an underside location of the door at a first end, the hinge bracket having a widthwise extending pin at a second end which is pivotally supported within circular capture recesses defined in a subset area of the pocket shaped body to permit the door to be pivoted from the upper rim edge to an open position. A detent cam mechanism is provided for biasing the door at each of the closed and open positions.

A fuel tank for a vehicle includes a main tank comprising a first tank volume defined by an outside wall and an auxiliary tank extending from an aperture provided in the outside wall. The auxiliary tank is formed as a pocket-shaped continuation of the outside wall into the first tank volume bounded by the outside wall. The auxiliary tank forms a second tank volume which is separated from the first tank volume and opens into a filler neck which runs inside the first tank volume and emerges on the outside wall of the main tank.

A system for controlling shut-off of a fuel pump nozzle in a fuel tank includes: a fuel evaporation gas blocking unit configured to separate an outer space of a fuel injection part of the fuel pump nozzle inserted inside the filler pipe into a first space into which external air is introduced and a second space into which fuel evaporation gas that is discharged from the fuel tank is introduced and to block the evaporation gas from being introduced into the first space; an external air suction jet pump mounted in the fuel tank and configured to suck external air thereinto and discharge the external air into the fuel tank, by receiving a portion of fuel transmitted from the fuel pump in the fuel tank as a working fluid; and a jet pump connection hose configured to connect the first space and the external air suction jet pump.

The invention is related to a new-generation fuel tank connection in all kinds of military vehicles, which enables a space reserved for the fuel tank to be used more efficiently, by reducing mounting space required according to the conventional methods. The invention is especially related to a new-generation fuel tank connection which comprises a sealed gasket (60) which has connection holes (62) to attach connection pieces (30) on the tank, which is produced from the materials suitable with fuel, which serves as leaking and vibration damping between fuel tank and sealing element (20), which has a conicity (64) in its inner surface (63) for ease of mounting of the sealing element (20), and a sealing element (20) which connects to the support (120) located on the vehicle roof (130) through connection holes (23) with connection pieces (30) and of which part entering into (63) the sealed gasket (60) tightened with clamp (50) has a conical (22) structure.

A control system is provided for a refuel or recharge door of a vehicle, which includes a vehicle controller. The system has a housing with a port, a door removably attached to the housing, a system controller, and at least one module. The system controller is communicably connected to a vehicle controller of the vehicle. Further, the system controller is configured to control the at least one module.
