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 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 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.

Methods and systems are provided for nozzle guides for vehicle refueling adapters. In one example, a nozzle guide includes a plurality of protrusions adapted to center a fuel nozzle within the nozzle guide and to reduce a likelihood of over-insertion of the fuel nozzle into the nozzle guide. The nozzle guide may include features such as a rear guard and upper wall adapted to reduce ingression of liquid fuel with fuel vapor flowing from the fuel tank.

A fuel-urea injection apparatus including a common inlet for a vehicle may include a filler neck including the common inlet, into which a fuel injection nozzle and a urea injection nozzle, are inserted, a detector detecting whether the injection nozzle inserted into the filler neck is the fuel injection nozzle or the urea injection nozzle, a switchover valve mounted at a common injection pipe connected to the filler neck, a urea injection pipe connected between a urea outlet of the switchover valve and a urea tank, a fuel injection pipe connected between a fuel outlet of the switchover valve and a fuel tank, and a controller controlling an operation of the switchover valve in accordance with the injection nozzle detected by the detector as being inserted into the filler neck to supply either fuel or urea to the corresponding outlet of the fuel and urea outlets.

The present disclosure relates generally to a fuel monitoring system for vehicles. More specifically, an embodiment of the system includes a hollow tube insertable into a filler tube of a fuel reservoir. The hollow tube has a first end defining an opening for receiving a fuel nozzle and a cap connectable to the first end. The system also includes a sensor that produces a signal representative of an amount of fuel flowing through the hollow tube.

A movement permitting section is provided at a nozzle guide 22 at an interior of an inlet pipe 14. When a stopper 24 receives pushing force toward a fuel tank side from a refueling nozzle 18, the movement permitting section deforms so as to permit movement of the stopper 24 toward a radial direction outer side of the nozzle guide 22 or toward a fuel tank side.

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.

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.

A tank filler neck including a filling line having an insertion end further away from the tank, designed to temporarily insert a breather pipe into the end region of the filling line further away from the tank, a passage line end closer to the tank, designed for passing through liquid in the direction away from the insertion end, a ventilation volume designed for through-flowing gas while passing liquid through the end of the passage line, a ventilation line which ends at a distance from the filling line and which can be blocked or released by a ventilation valve for through-flowing gas, a detecting device designed to detect a passage-ready state and/or a passage state of the filling line, and an operating device designed to adjust, as a function of the detection result of the detecting device, the ventilation valve between the blocking position and the release position.
