A custom blending hose for manifold mixing of various fuels for a fuel dispensing system, including a pair of fuel dispensing hoses, generally concentrically or coaxially arranged, for passing at least a pair of fuels into a manifold assembly, for blending and intermixing of said fuels, for further delivery through a dispensing hose assembly, to a nozzle, for refueling of a vehicle. The manifold includes a housing, incorporating internally a series of apertures, through which the fuels are passed, and blended, for delivery as a uniform fuel to a vehicle during dispensing. A vapor return line may locate through the manifold.

Methods and systems are provided for refueling a vehicle configured with an onboard refueling vapor recovery (ORVR) system, such that a loading of a fuel vapor canister configured to capture and store fuel vapors, is reduced. In one example, during the refueling, a rate at which fuel vapors are routed to the fuel vapor canister is adjusted responsive to an indication that the vehicle is refueling at a gas station equipped with offboard fuel vapor recovery infrastructure. In this way, loading of the fuel vapor canister may be reduced which may prevent undesired bleedthrough emissions resulting from a canister loaded with fuel vapors, particularly in examples where the vehicle is a hybrid vehicle and where engine runtime is limited, thus limiting potential opportunities for purging of the fuel vapor canister.

The present invention relates to a system and assembly for refilling a reservoir with liquid dispensed from a dispenser, in particular, but not exclusively, to a system and assembly for the substantially leak-free refilling of the reservoir of a smoking-substitute device with a liquid comprising nicotine from a refill dispenser. The assembly is configured to provide a gas communication pathway through the assembly and physically separate from the liquid communication pathway for venting gas from an end of the assembly proximal the first aperture to an exterior of the assembly responsive to the movement of the assembly to the secured and open configuration, the assembly configured to close the gas communication pathway in the unsecured and closed configuration.

A filling system for an electronic cigarette (10) is disclosed in which a nozzle (38) of a liquid dispenser (80) contains a plunger (62) which is biased by a spring (60) into a closed position in which liquid is prevented from flowing through the nozzle (38). In use the nozzle (38) is inserted into an open end (42) of a liquid reservoir (34) for an electronic cigarette containing an air tube (32). The plunger (62) engages with the end of the air tube (32) blocking the air tube (32) and opening the liquid flow path through the nozzle (38). The arrangement of the plunger (62) and nozzle (38) is such that operation of the plunger (62) only occurs when the nozzle (38) engaged within a liquid reservoir (32). A membrane (96) can be provided to prevent leakage from the liquid reservoir (34) when the nozzle (38) is disengaged.

Configuring a high-vapor-pressure (HVP) material comprising a plurality of component hydrocarbons; flashing the HVP material from an HVP liquid to an HVP vapor as the HVP liquid is introduced into an evacuated portion of a containment vessel; introducing a relief mass from a process relief event occurring outside the containment vessel to mix with the HVP material in the containment vessel; and distributing energy from the process relief mass within the containment vessel using a plurality of energy absorption processes in the component hydrocarbons as the plurality of component hydrocarbons respectively condense to liquid phases over time. The evacuated portion of the containment vessel may be a headspace vacuum above a low-vapor-pressure (LVP) liquid within the containment vessel. The HVP material may comprise C4-C10 hydrocarbons. The HVP material may comprise a plurality of component hydrocarbons having diverse boiling points and vapor pressures, that absorb and distribute the relief mass energy.
