Systems are provided for refueling a fuel tank of a motor vehicle via a funnel including an insert. In one example, a system may include a funnel including an insert coupled to an inner circumference of the funnel, the insert including a plurality of projections positioned on an inner perimeter of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

A closing member includes a pair of flap members, and an urging device urging each flap member to be positioned at a closed position closing a near-side pass-through opening for a fuel filling nozzle. Each flap member includes a turning assembly portion which becomes a center of turning, and an abutment portion relative to the other of the flap members. A far-side pass-through opening for the fuel filling nozzle, and a guide slope face for the fuel filling nozzle, which is a slope face having an opening edge of the far-side pass-through opening as a slope lower end and a vicinity of the near-side pass-through opening as a slope upper end and formed on both sides of a directly underneath position including the directly underneath position of the abutment portion of the flap member located at the closed position, are formed on a far side of the closing member.

A flame mitigation device (FMD) for use within a portable fuel container includes a generally cylindrical body having an interior sidewall and exterior sidewall. An annular rim is configured at an upper end of the body and a bottom wall is further configured at a lower end of the body. The FMD includes one or more indented fuel flow members extending from the interior of the annual rim for decreasing cyclonic effect of fuel flowing into the body and a plurality of stepped ribs configured on the interior sidewall of the body for centering diesel and gasoline fuel pump nozzles when inserted into the body. A reverse domed shaped bottom help to disperse fuel though a plurality of substantially rectangular shaped holes through the side wall and bottom wall.

A refueling retainer comprises a body portion of a tubular shape inserted into and arranged at a fueling-side end portion of an inlet pipe through which fuel is introduced to a fuel tank. The body portion comprises at a leading end portion thereof: a tapered portion, which is an inner peripheral surface of the leading end portion inclined radially inward toward a leading end of the body portion; and a claw portion that projects from the leading end of the body portion in an inwardly bent manner.

A capless fuel system comprises a fuel inlet body, a flapper pivotably mounted within the fuel inlet body, a biasing member associated with the flapper, an axially movable shaft associated with the biasing member, and a tension calibrator associated with the biasing member, whereby tension on the controller spring may be adjusted by the calibrator. The biasing member may be of a variety of biasing elements but is preferably a controller spring. The shaft is reversibly movable from a tensioning position in which the electromechanical driver assembly is deactivated to a tension-lowering position in which the electromechanical driver assembly is activated. The capless fuel system includes a fuel pump nozzle position sensing system. The capless fuel system relies upon a single, multi-function flapper that functions as both the capless fuel system debris cover and a sealing member to prevent evaporative emission leaks.

A vehicle has a fuel system that includes a controller that determines when the vehicle is in a refuel mode or a run mode based on a connection of a refuel nozzle to a vehicle connection of the vehicle. The controller controls a fuel pump input selector, a vehicle fuel pump, and a fill/run fuel selector such that fuel is pumped from a storage tank external to the vehicle into a vehicle fuel tank by way of the vehicle fuel pump in the refuel mode, and fuel is pumped to an engine of the vehicle from the vehicle fuel tank by way of the vehicle fuel pump in the run mode.

A system that includes a vehicle fuel-receiver comprising a port located on a vehicle surface; and an onboard computer programmed to: send a fuel delivery request to an unmanned aerial vehicle (UAV); actuate the port to permit the UAV to deliver fuel; and instruct a communication module to transmit a beacon signal to the UAV.

Systems are provided for refueling a fuel tank of a motor vehicle via an insert for a filler pipe. In one example, a system may include an insert coupled to an inner circumference of the filler pipe, the insert including a plurality of projections positioned on an inner circumference of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

A computer that includes a processor and memory which stores instructions executable by the processor. The instructions include: initiate, from a vehicle, a fuel delivery request for fuel delivery by an unmanned aerial vehicle (UAV); in response to the initiation, instruct a communication module in the vehicle to transmit a beacon signal to enable the UAV to locate the vehicle; and coordinate a docking procedure between the UAV and the vehicle to receive fuel from the UAV.

Disclosed is an inlet end piece for the tank inlet of a motor vehicle, having a closure insert arranged in an upper area of a pipe inlet, having a filling opening and a sealing flap which counter to the force of a closure spring by way of a gas pump nozzle is capable of being opened by pivoting, and is held in the closed state by the closure spring. The inlet end piece has an indicator means having an indicator area, wherein the indicator means in the case of a closed sealing flap is located in an inactive position in which an indicator area of the indicator means is not visible to the user, and in the case of the sealing flap being at least partially opened, the indicator means is displaced into a signal position in which the indicator area becomes visible.
