A refueling control system for an internal combustion engine includes a fuel tank; a vapor pipe; a step motor-driven shut-off valve; a fuel filler lid; and an electronic control unit configured to, when the fuel filler lid is to be opened, i) drive the shut-off valve such that the shut-off valve is opened, ii) close the fuel filler lid when an opening degree of the shut-off valve is less than a set opening degree, and iii) open the fuel filler lid when the opening degree of the shut-off valve is greater than or equal to the set opening degree. The electronic control unit sets the set opening degree such that the set opening degree when an opening speed of the shut-off valve is low is greater than the set opening degree when the opening speed of the shut-off valve is high.

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 fuel filler lid assembly includes a fuel filler lid. The fuel filler lid is configured to be supported to a vehicle body that has a fuel filler opening. The fuel filler lid has a first part that is movable with respect to the vehicle body between an open state and a closed state. The open state enables access to the fuel filler opening. The closed state encloses the fuel filler opening. The fuel filler lid has a second part that is movable with respect to the first part as the first part moves between the open state and the closed state.

A component for filling a liquid into a liquid container has a filler neck that comprises a filler opening and an outflow portion that can be connected to the liquid container and has an outflow opening. At least one intermediate portion is located between the filler neck and the outflow portion and which, at least in a part adjoining the filler neck, forms at least one widening of the component relative to the filler neck for calming a liquid filled into the component.

A valve member provides for the flow of vapors from a fuel tank of an internal combustion engine to escape the fuel tank. The valve member may include a valve and a boss or spacer. The valve is configured to selectively control the flow of vapor from the fuel tank. The boss or spacer is positioned in a predetermined relationship to the valve, and the boss or spacer prevents a deformation of the valve from disrupting the selectively controlled flow of vapor from the fuel tank.

A filling head for introducing operating fluid into an operating fluid tank of a motorized vehicle, where the filling head includes: A filling head housing, where the filling head housing exhibits a delivery-accommodation region for accommodating delivery devices, A venting structure, which during a transmission of operating fluid through the filling head housing allows transmission of gas, Where the delivery-accommodation region exhibits a plug-in nozzle extending along a virtual nozzle path with a plug-in orifice through which an accommodating space is accessible, Where in the filling head housing, at an axial magnet distance from the plug-in orifice, there is arranged a magnet arrangement, Where the venting structure includes a channel arrangement which is bounded by an inner wall of the plug-in nozzle and by an outer wall of the plug-in nozzle, wherein from the plug-in orifice as far as and into the extension region of the magnet arrangement there proceeds a gas-impermeable boundary surface which bounds the accommodating space radially outward, where a cross-sectional area enclosed by the boundary surface and orthogonal to the nozzle path is at least not larger in the extension region of the magnet arrangement than in a reference region located between the magnet arrangement and the plug-in orifice.

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.

A fuel filler structure includes a vehicle body panel, a filler housing, a filler tube cap and a tether. The vehicle body panel defines a fuel filler opening. The filler housing has an outboard side and an inboard side. The outboard side is installed to the vehicle body panel at least partially surrounding the fuel filler opening and is dimensioned to receive and surround a portion of a fuel filler tube. The filler tube cap is configured to removably attach to the fuel filler tube at least partially within the filler housing. The tether is attached at a first end to the filler tube cap and is attached at a second end to the filler housing for pivoting movement about a vertical axis.

A fuel filler lid assembly includes a fuel filler lid. The fuel filler lid is configured to be supported to a vehicle body that has a fuel filler opening. The fuel filler lid has a first part that is movable with respect to the vehicle body between an open state and a closed state. The open state enables access to the fuel filler opening. The closed state encloses the fuel filler opening. The fuel filler lid has a second part that is movable with respect to the first part as the first part moves between the open state and the closed state.

A diesel exhaust fluid (DEF) cap assembly for a vehicle includes: a body having a first opening and a second opening arranged at an opposite side of the first opening, the second opening configured to be opened and closed; a flange portion protruding radially outward between the first opening and the second opening of the body, and having a plurality of through holes and a flange gasket configured to be sealably coupled to a mounting subject on which the flange portion is mounted; and a membrane member coupled to the flange portion, and configured to cover the plurality through holes and allow air flow.
