A flow booster for optimizing flow of fuel passing into an aircraft. The flow booster includes a fuel intake fluidly coupled to the fuel circuit, and includes a housing and a piston. The piston has a piston head slidably movable in the housing to define h a variable fuel inlet to receive the fuel. The fuel applies a fuel force to the piston. An intake tuner is operatively connected to the fuel M intake, and has a tuning force applied to the piston against the fuel force. A trigger is coupled to the intake tuner to vary the tuning force applied by the intake tuner. The flow regulator is coupled to sensors to receive fuel measurements. A flow regulator is operatively connected to the trigger to activate the trigger in response to the fuel measurements whereby the flow of the fuel into the aircraft is continuously adjustable during refueling.

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.

In an example, a method of supplying fuel to a fuel tank of a vehicle includes supplying, via a fuel line, fuel to a fuel tank of a vehicle at an initial rate of fuel flow. The act of supplying the fuel causes an electrostatic charge to accumulate on a surface of the fuel in the fuel tank. The method also includes determining a level of ionization of an air medium in the fuel tank, and determining an increased rate of fuel flow based on a difference between the determined level of ionization and a baseline level of ionization. The electrostatic charge accumulated on the surface of the fuel dissipates at an increased rate when the determined level of ionization of the air medium is higher than the baseline level of ionization. The method further includes supplying the fuel to the fuel tank at the increased rate of fuel flow.

A fuelling method is described which comprises the steps of dispensing an initial quantity of fuel to a fuel tank, waiting for a predetermined settling period for the fuel dispensed to the fuel tank to homogenise and settle, after the predetermined settling period has elapsed, taking a fuel quantity reading using a fuel gauge associated with the fuel tank, calculating a differential volume of fuel between the fuel gauge reading and a desired final fuel quantity, and dispensing to the fuel tank a volume of fuel substantially equivalent to the differential volume using a dispensing apparatus including a fuel volume meter.

A counter mountable fluid dispenser includes a below deck assembly and an above deck assembly. The below deck assembly includes a reservoir for storing a fluid, a dispensing mechanism in fluid communication with the reservoir, and a controller in circuit communication with the dispensing mechanism for operation of the dispensing mechanism. The above deck assembly includes a spout defining an outlet port in fluid communication with the reservoir for dispensing fluid stored in the reservoir upon operation of the dispensing mechanism, an external supply port in fluid communication with the reservoir by a supply passage to supply fluid to the reservoir, an access door movable between a closed position blocking access to the external supply port and an open position permitting access to the external supply port, and a switch mechanism configured to disable the dispensing mechanism when the access door is in the open position.

A removable fuel handle brace is provided, comprising: a pair of parallel horizontal sides, each having a hook on an inner end bent approximately 180 in a first direction; a pair of parallel vertical sides having a first end extending from an outer end of each horizontal side approximately 90 in a second direction opposite the first direction; an upper cross-piece connecting second ends of the vertical sides; a lower cross-piece having first and second ends connected to the vertical sides between the first and second ends of the vertical sides; and a pair of horizontal extensions connected to the first and second ends of the lower cross-piece and extending in a direction towards the hooks parallel to the horizontal sides.

An improved fluid transfer accuracy, information collection, and overall management. A system may utilize a pump to transfer fluid from a source to a target vessel, a meter for measuring an amount of fluid transferred, a density meter to detect actual fluid density, and a control unit to determine actual fluid transfer amount based on density. As an example, a fluid flow meter can be coupled with a flow conduit to determine fluid volume, along with the density meter to detect real-time density of transferred fluid. During a fluid transfer event, such as aircraft refueling, LPG fueling, or other refined fuels or valuable liquids, fluid volume can be converted to fluid weight in real-time based on actual density. The real-time fluid weight can be used to determine if a target fluid weight has been reached, and fluid flow can be shut off at the appropriate time.

A system for effecting automatic identifying of a receiving aircraft receiving fuel from a fuel delivery apparatus in a delivering aircraft during an airborne fueling operation includes: (a) a first unit coupled with the receiving aircraft; (b) a second unit coupled with the delivering aircraft; and (c) a processing unit coupled with at least one of the first unit and the second unit. The first and second units cooperate to effect communicative coupling for conveying identifying information between the receiving aircraft and the delivering aircraft. The processing unit cooperates with at least one of the first unit and the second unit for employing the identifying information to effect the identifying.

A vehicle control device for a vehicle includes a communication unit configured to communicate with a communication device located at a gas station, and a processor configured to control the vehicle to perform at least one of autonomous driving or autonomous fueling based on information received from the communication device. In addition, a control method for controlling a vehicle includes communicating with a communication device located at a gas station, and controlling a vehicle to perform an operation based on information received from the communication device.

An object is to suppress excessive insertion of a fueling nozzle during fueling. A nozzle guide configured to form a nozzle guide path that guides a fueling nozzle is placed inside of a filler neck main body configured to include a fuel passage that introduces a fuel supplied from the fueling nozzle toward a fuel tank. This nozzle guide comprises a first projection for nozzle restriction provided on a nozzle guide end opening portion at an end of the nozzle guide path along a nozzle guide direction and protruded from an end opening circumferential wall of the nozzle guide end opening portion to narrow at least part of a diameter of the nozzle guide path; and a second projection for nozzle restriction provided on a downstream side of the first projection along the nozzle guide direction and protruded from the end opening circumferential wall to narrow at least part of the diameter of the nozzle guide path.
