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.

An overflow risk mitigation system for a large aboveground liquid storage tank includes a conduit mounted to an outside of the storage tank and extending from an overflow release port disposed in an upper portion of the storage tank to a lower portion of the storage tank. The conduit is closed and channels liquid overflow from the tank to a ground level while minimizing the production of mist or aerosol. The conduit can extend substantially vertically downward from the overflow release port, can have a cross sectional area substantially larger than that of the overflow release port and that expands downwardly from the release port, and can include a diffusive media at an outlet thereof. The overflow release port may be one of a plurality of release ports disposed at a same elevation around a periphery of the tank to allow for flow of liquid exceeding a maximum storage level.

An exemplary system for improving gaseous venting from a fluid storage vessel includes a hollow member configured to receive a fuel nozzle, the fuel nozzle having an aspirate opening, a vent line fluidly connecting the fluid storage vessel and the hollow member, and a flow guide device fluidly connected to the hollow member and the vent line. The flow guide device includes a flow guide chamber having an inlet, a plurality of sidewalls, and an outlet, and a plurality of directional blades formed within the flow guide chamber. The plurality of directional blades direct a fluid flow through the flow guide chamber and the hollow member toward the aspirate opening of the fuel nozzle.

A valve for a vapour recovery system including a valve body having an inlet and an outlet, a valve seat within the valve body, a valve closure member releasably engageable with the valve seat, a socket portion for receiving a pipe member, a plurality of engagement members configured to be releasably engageable with a portion of a pipe member received in the socket portion for releasably retaining the pipe member in the socket portion, and an actuation member mounted on the valve body. The actuation member includes a recess for receiving each of the engagement members and is displaceable between a first position in which the engagement members are received in the recesses in the actuation member, and a second position in which the actuation member urges the engagement members inwardly towards a deployed configuration in which they engage with and retain a pipe member located in the socket portion.

Embodiments of systems and methods for transporting liquefied gas and carbon dioxide (CO2) in a dual-fluid vessel thereby minimizing transportation between locations are disclosed. In an embodiment, the dual-fluid vessel has an outer shell with an outer surface, an outer compartment within the outer shell configured to store liquefied gas, a bladder positioned within the outer compartment configured to store CO2, and insulation positioned between the outer shell and the outer compartment to provide temperature regulation for the liquefied gas when positioned in the outer compartment and CO2 in the bladder.

A serving utensil comprises a handle having a gripping portion that is gripped by the user, A serving receptacle is operatively connected to the handle. There is mounted to the serving utensil a serving scraper having a resilient arm with a bowed shape. The resilient arm has a scraping end and a mounting end. A mounting means at the mounting end is for mounting the resilient arm to the serving utensil forwardly of the gripping portion of the utensil used to grip the utensil and rearwardly of the serving-receptacle. A scraper-remover is disposed at the scraper end of the resilient arm so that food can be scraped off of the food receptacle of the utensil when the serving scraper is actuated by the user.

An apparatus for reducing hydrocarbon emissions from vehicles is disclosed, wherein the apparatus includes a first chamber, a second chamber, and an inlet which, in use, allows vapor from a fuel tank to be introduced into the first chamber, characterized by a distributor which distributes vapor from the fuel tank in the first chamber.

A tank passage is connected at its one end to a fuel tank, which stores fuel. A canister is connected to the other end of the tank passage and adsorbs evaporated fuel generated by evaporation of fuel in the fuel tank. An electric control valve is operable with current supply to control an amount of fluid flowing through the tank passage by varying an open rate of the tank passage. A fill-up detection part detects that the fuel tank is filled up with fuel based on a fuel level in the fuel tank. A control part controls an operation of the electric control valve. The control part controls the electric control valve in the valve closing direction, which decreases the open rate, when the fill-up detection part detects that the fuel tank is filled up with fuel.

An electromechanically operated fuel nozzle having continuously adjustable flow rate settings between a closed position and maximum flow. The fuel nozzle includes a fuel dispensing pipe for dispensing fuel; an electromechanical valve device to control a flow of fuel in the fuel dispensing pipe, comprising an inlet pipe and an outlet pipe. The electromechanical valve device comprises at least one continuously variable flow electromechanical valve to control the flow of fuel; an electronic board for operating the at least one continuously variable flow electromechanical valve; and electric accumulator means for electrically powering the at least one variable flow electromechanical valve and the electronic board such that the predetermined portions provide the particular one of the flow rate settings. The electromechanical valve preferably comprises a servomotor controlled ball valve.

A closed tank system includes: a fuel tank; a canister adapted to adsorb evaporative fuel generated in the fuel tank; a fill-up limiting valve provided inside the fuel tank so as to be communicated with the evaporative fuel discharge passage and adapted to operate to close the evaporative fuel discharge passage when a fuel level reaches a predetermined full tank liquid level; a shut-off valve adapted to operate to open or close the evaporative fuel discharge passage; a fuel remaining amount sensor adapted to detect a remaining amount of fuel; and a hardware processor that causes a control section to carry out control for allowing the shut-off valve to be opened or closed. The hardware processor causes the control section to inhibit the control for allowing the shut-off valve to be opened when an engine is in operation and the detected remaining amount of fuel exceeds a predetermined threshold.
