A system for dispensing an additive into a fuel is disclosed. The system includes: a tank for holding a fuel additive and a dispenser. The dispenser includes: a main shutoff valve; a bore through which the fuel passes; a float bowl, contained within the walls of the device surrounding the bore; an obstruction located inside the bore of the dispensing device; a seal to prevent the flow of air around the outside of the fuel nozzle pump. The additive tank is connected to the dispenser by a conduit. Gravity causes the additive to flow from the tank, through the conduit into the dispensing device. The main shutoff valve is activated as a device cap is installed and deactivated as the cap is removed. The obstruction causes the additive to be drawn into the flow of fuel within dispensing device.

A method can be used to form a plastic filler neck for a vehicle. The method includes providing a fuel injection pipe comprising a polyamide material containing nanoclay and having a single layer structure in cross-section, inserting and fastening a retainer into an internal space of a tip of the fuel injection pipe to support a refueling gun, directly fastening a cap holder to the tip of the fuel injection pipe, and mounting an air drain casing to an outer diameter portion of the cap holder fastened to the fuel injection pipe using a mounting bracket.

A vehicle equipped with a high pressure tank has mounted in the interior of a vehicle body a high pressure tank having a resin liner and a reinforced layer, the vehicle comprising a tank chamber, a filling port, a concave portion in which the filling port and a ventilation port are disposed, a fuel lid capable of opening and closing an opening of the concave portion, and a ventilation passage that allows communication between the ventilation port and the tank chamber. When the fuel lid is opened, the ventilation port is opened to the exterior of the vehicle body, whereas when the fuel lid is closed, the ventilation port is covered by the fuel lid in a state in which the ventilation port is allowed to communicate with the exterior of the vehicle body.

A plastic filler neck for vehicles includes a fuel injection pipe, a retainer inserted and fastened into an internal space of a tip of the fuel injection pipe to support a refueling gun, a cap holder directly fastened to the tip of the fuel injection pipe by fusion, and an air drain casing mounted, by a mounting bracket, to an outer diameter portion of the cap holder fastened to the fuel injection pipe.

Disclosed is an apparatus for controlling shut-off of a fuel gun in a filler pipe of a fuel tank which inhibits early shut-off of the fuel gun before the fuel tank is fully filled with fuel while refueling. The apparatus includes: a retainer mounted in a filler neck of the fuel tank; a partition disposed in a space between an inner circumferential surface of the filler neck and an outer circumferential surface of the retainer and having a fuel intake hole formed in a lower end of the partition; and an early shut-off prevention valve disposed in the partition. The early shut-off prevention valve closes the fuel intake hole before the fuel tank is fully filled with fuel, and opens the fuel intake hole by fuel flowing to the filler neck from the fuel tank when the fuel tank is fully filled with the fuel.

The present disclosure provides a vehicle fluid delivery system comprising (a) a housing defining a first cavity, wherein the housing includes a first side and a second side opposite the first side, the first side and the second side being separated by a continuous side wall extending around their peripheries, and wherein the housing is adapted to be removable from a vehicle, (b) a fluid reservoir positioned in the first cavity of the housing, (c) a fluid port coupling disposed on the first side of the housing and providing fluid access to the fluid reservoir, and (d) a fluid barrier external to and contiguous with the side wall.

A filler neck (1) for filling an operating substance, such as fuel or AdBlue® or urea, or an additive, such as water, into a vehicle tank by way of a fuel pump nozzle. The filler neck (1) has a filler neck body (2), which can be accommodated in a filler pipe leading to the vehicle tank. The filler neck (1) furthermore has a fuel pump nozzle guide with an insertion section (4) for guiding a fuel pump nozzle, which is accommodated or is to be accommodated in the filler neck body (2), in the direction of the vehicle tank. The filler neck body (2) and the insertion section (4) of the fuel pump nozzle guide are formed together as an integral casting, in particular plastics injection moulding.

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 fuel fill opening structure for a fuel tank includes a fuel filler pipe, a fuel fill opening, and a flow guide. The flow guide includes a main guide wall which partitions a fuel introduction region inside the fuel filler pipe into an upper space communicating with a tank main body side and a lower space communicating with the fuel fill opening side, and a partition wall provided to be continuous with the main guide wall and configured to close a space between an upper surface side of the main guide wall and an inner surface of the fuel filler pipe. The main guide wall includes a bent inclined part that is bent and inclined downward from a middle portion in running from the fuel fill opening side toward the tank main body side. The bent inclined part has a shape in which a width thereof becomes smaller when viewed from above as it inclines downward.
