Disclosed is a wheeled vehicle. The wheeled vehicle includes various features for operation by a rider, such as a throttle actuation assembly and various components for operation and manipulation of the vehicle.

A fuel tank assembly for a motorcycle. The fuel tank assembly includes a fuel tank defining a fuel containment volume. The fuel tank has an upper wall. A fuel cap is operable to selectively open and close the fuel containment volume. A motorcycle accessory is attachable to the fuel tank via a connection structure including first and second connection portions that are complementary and inter-engageable together to positively define a fully-secured state. The first connection portion is secured to an exterior surface of the upper wall of the fuel tank, and the second connection portion is secured to the motorcycle accessory. The connection structure defines a finite position and rotational orientation of the motorcycle accessory upon relative rotation of the motorcycle accessory with respect to the fuel tank to the fully secured state.

A method for detecting the closure status of a fuel tank closure of a motor vehicle and to a device for carrying out this method.

A four-wheel vehicle includes an engine at least a portion of which is located farther forward than a seat, a fuel tank located above the engine and forwardly of the seat, a fuel filler including a fuel filler neck and a filler cap, a breather channel connected to the fuel filler, and an outflow prevention valve in the breather channel to prevent outflow of liquid fuel. The outflow prevention valve is located higher in a side view of the vehicle body than both of a lower end of the fuel tank and an upper end of the engine.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.

A filler and/or charger flap liner (3) is provided with a seal arrangement. The filler and/or charger flap liner (3) is to be arranged in an opening (6) of an outer side part (4) and in an opening (7) of an outer wheel arch (5). The filler and/or charger flap liner (3) is to be arranged with a first bearing element (8) on an edge of the opening (6) of the outer side part (4) and is to be arranged with a second bearing element (9) on an edge of the opening (7) of the outer wheel arch (5). An at least partially circumferential sealing element (10) is arranged radially outside the openings (6, 7) of the outer side part (4) and the outer wheel arch (5).

A closing device for a filler port comprises an inlet box configured to form the filler port; a lid configured to rotate about a first rotating shaft that is fixed to the inlet box, such as to open and close a surface of the inlet box; and a fuel passage-forming portion configured to form a fuel passage. The lid includes a plate-like lid main body portion configured to rotate about the first rotating shaft, and an open-close mechanism provided on an inner side of the lid main body portion as a separate body from the lid main body portion and configured to be rotatable about the first rotating shaft such as to open and close an opening. When the lid is opened from a closed position, the lid main body portion and the open-close mechanism are opened integrally. This configuration suppresses dirt or the like adhering to a surface of the open-close mechanism for the filler port from entering a fuel tank.

A compartment wall structure defines a fuel filler compartment that includes a tube receiving opening and a vent opening. A fuel receiving end of a fuel filler tube is located at the tube receiving opening of the fuel filler compartment. A fuel tank attachment end thereof is located outside the fuel filler compartment and is spaced apart from the compartment wall structure. An air vent structure is in fluid communication with the vent opening. The air vent structure defines a chamber opening connected via a vent line to a fuel vapor filter canister. Vapor from the fuel filler compartment is vented to the fuel vapor filter canister through the chamber opening. The air vent structure has a screen at the chamber opening to prevent entry of objects, such as, for example, insects and/or debris through the chamber opening.

A fuel tank cap includes a casing; a main chamber disposed in the casing; a vapor vent channel disposed in the casing and communicating with the main chamber; annular partition walls disposed in the main chamber and configured to divide the main chamber into troughs surrounding a central tunnel, each partition wall including a cut so that the troughs and the tunnel are capable of communicating with each other via the cut; activated carbon filled in the troughs; and a permeable plug disposed in the tunnel, which is made by wrapping rust-resistant flexible wires so that a plurality of intercommunicated air gaps are formed among the flexible wires. The vapor vent channel includes the cuts, the troughs and the air gaps. The activated carbon captures fuel vapors and absorbs VOCs in the fuel vapors when the fuel vapors pass through the vapor vent channel.

This disclosure relates to direct fill fueling systems and devices for filling and venting a tank. A direct fill fueling system can include the tank, a fill neck for receiving a nozzle, and a nozzle bounding member for setting an insertion depth of the nozzle received by the fill neck. The nozzle bounding member can include a stop that can be aligned with the opening of the fill neck and configured to obstruct the motion of the nozzle, when the nozzle is inserted into the fill neck. The nozzle bounding member can be provided as a tubular insert. The tubular insert can include the stop. The stop can include one or more locating slats positioned at an end of the tubular insert.
