Abstract: A fuel-tank filler apparatus includes a fuel-tank filler neck and a filler neck closure. A flapper door is provided to control access to a fuel-conducting passageway formed in the fuel-tank filler neck.

Abstract: A vehicle fuel system includes a vapor recovery canister containing a primary carbon bed and a secondary carbon bed. Each carbon bed is configured to capture hydrocarbon material associated with fuel vapor discharged from a vehicle fuel tank.

Abstract: A capless filler neck closure for use with a vehicle fuel tank filler neck is disclosed. The capless filler neck closure includes an outer dust cover and an inner closure door each movable from a closed position to an opened position in response to insertion of a fuel nozzle into the capless filler neck closure for refueling of an associated vehicle fuel tank.

Abstract: A filler neck closure assembly includes a nozzle-receiving housing associated with a vehicle fuel tank filler neck. The nozzle-receiving housing is formed to include a central housing passageway sized to receive the tip of a fuel-dispensing pump nozzle therein during refueling of the fuel tank.

Abstract: A fuel tank vent valve includes a venting apparatus for regulating discharge of fuel vapor from a fuel tank and admission of outside air into a fuel tank. The vent valve is used to regulate pressure in a fuel tank.

Abstract: A fuel tank apparatus is adapted to conduct fuel toward the fuel tank of a vehicle. The fuel tank fill apparatus includes a fuel-tank filler neck for conducting fuel to the fuel tank and a capless closure assembly the couples to the fuel-tank filler neck in such a way so as to be removed for serviceability.

Abstract: A filler neck cap is adapted to mate with and close a filler neck. The filler neck cap includes a closure configured to engage the filler neck, an outer handle configured to be gripped by a consumer, and a torque-transmission member configured to transmit torque applied to the outer handle by the consumer to the closure to rotate the closure relative to the filler neck during installation of the cap in the filler neck and removal of the cap from the filler neck.

Abstract: A nozzle inhibitor is adapted to be arranged in a filler neck included in a fuel-tank fill tube and is configured to allow only a diesel fuel nozzle having an outer diameter that is greater than a specified minimum diameter to be inserted into the fill tube to a depth sufficient so that a user may dispense diesel fuel from that nozzle into the fill tube. The nozzle inhibitor inhibits insertion of a small-diameter unleaded fuel nozzle into the fill tube, yet allows insertion of a relatively larger diameter diesel fuel nozzle into the fill tube so that only diesel fuel is dispensed into a diesel fuel tank coupled to the fill tube.

Abstract: A vehicle fuel system includes a vapor recovery canister containing at least two carbon beds. Each carbon bed is configured to capture hydrocarbon material associated with fuel vapor discharged from a vehicle fuel tank into the canister.

Abstract: A fluid regulator for an engine coolant system includes a thermostat. The thermostat is configured to route engine coolant through an engine and a radiator in one mode and through the engine to bypass the radiator in another mode.

Abstract: A nozzle inhibitor is adapted to be arranged in a filler neck included in a fuel tank fill tube and is configured to allow only a diesel fuel nozzle having an outer diameter that is greater than a specified minimum diameter to be inserted into the fill tube to a depth sufficient so that a user may dispense diesel fuel from that nozzle into the fill tube. The nozzle inhibitor inhibits insertion of a small-diameter unleaded fuel nozzle into the fill tube, yet allows insertion of a large-diameter diesel fuel nozzle into the fill tube so that only diesel fuel is dispensed into a diesel fuel tank coupled to the fill tube.

Abstract: A fuel tank vent apparatus for controlling discharge of fuel vapor from an interior region in a fuel tank includes a housing and a valve received in the housing that moves between an open position and a closed position. The valve assumes the open position when the fuel level in the fuel tank is relatively low and the valve assumes the closed position when the fuel level in the fuel tank is relatively high.

Abstract: A vehicle fuel system includes a vapor recovery canister containing at least two carbon beds. Each carbon bed is configured to capture hydrocarbon material associated with fuel vapor discharged from a vehicle fuel tank into the canister.

Abstract: A fuel system includes a fuel tank filler neck associated with a fuel tank. The fuel tank filler neck includes a fill tube for receiving a fuel-dispensing pump nozzle and a fuel conductor interconnecting an interior region of the fuel tank and a passageway formed in the fill tube.

Abstract: Inlet control valves for use with fuel delivery systems are described. An example inlet control valve includes a first body portion having a first coupling to define an inlet of the control valve and one of a plurality of fasteners or a plurality of slots opposite the inlet. A second body portion coupled to the first body portion to define a fluid flow passageway, where the second body portion has a second coupling to define an outlet of the control valve and the other one of the plurality of fasteners or the plurality of slots opposite the outlet. The first plurality of slots receives the first plurality of fasteners when the first body portion is coupled to the second body portion. A valve is pivotally coupled relative to the first and second body portions to control fluid flow through the passageway.

Abstract: An exhaust after-treatment system associated with a diesel engine includes a diesel exhaust fluid storage unit. The storage unit includes a diesel exhaust fluid tank and a vent system coupled to the tank and configured to regulate flow of air into the tank and fluid vapor out of the tank.

Abstract: A filler neck cap is adapted to mate with and close a filler neck.

Abstract: A nozzle inhibitor is included in a fuel tank filler neck closure assembly. The nozzle inhibitor blocks full insertion of a small-diameter unleaded fuel nozzle into the filler neck closure assembly yet allows full insertion of a large-diameter diesel fuel nozzle into the filler neck closure assembly.
