  • Patent number: 10378485
    Abstract: Methods and systems are provided for preheating a fuel vapor storage canister in an evaporative emissions system prior to a vehicle start. In one example, a method may include learning common vehicle routes and identifying routes in which fuel vapor storage canister preheating is indicated, such as routes that will enable fuel vapors to be purged to an engine intake shortly after the vehicle start. Then, in anticipation of an identified route for fuel vapor storage canister preheating, a vehicle controller may be transitioned from a sleep mode to an awake mode prior to the vehicle start in order to commence a fuel vapor storage canister preheating routine.

  • Patent number: 10378462
    Abstract: A vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced fuel components. A supply tank includes three compartments where the first contains the onboard fuel, the second receives a vaporized adsorbate from the separation unit and condenses at least a part of it into one of an octane-rich fuel component or a cetane-rich fuel component, while the third may either store the condensed and enriched fuel component or help condense more of the vaporized adsorbate. The condensing takes place through heat exchange between the onboard fuel and the vaporized adsorbate that are present within the various compartments of the supply tank.

  • Patent number: 10364763
    Abstract: A method is presented, comprising, during a first condition, including an active refueling event, receiving an indication of hydrocarbon breakthrough from the fuel vapor canister; and restricting flow of fuel vapor through a fuel vapor canister vent pathway responsive to the indication of hydrocarbon breakthrough. Restricting the fuel vapor canister vent pathway will cause fuel tank pressure to increase, thus triggering an automatic shutoff of a refueling dispenser. In this way, the refueling event may be terminated without releasing significant quantities of hydrocarbons into the atmosphere.

  • Patent number: 10337462
    Abstract: A system for an engine, comprising: a fuel vapor canister coupled to a fuel tank; a thermal jacket comprising a phase-change material, the thermal jacket spatially sheathing the fuel vapor canister; and an engine coolant passage positioned to transfer thermal energy between engine coolant and the phase-change material. In this way, the phase-change material may buffer the temperature of the fuel vapor canister by absorbing heat generated during hydrocarbon adsorption, and returning the heat to the vapor canister during hydrocarbon desorption. By coupling the phase-change material to engine coolant, the thermal capacity of the thermal jacket can be increased, as heated coolant can thus transfer thermal energy to the phase-change material to replace the thermal energy transferred to the canister during hydrocarbon desorption.

  • Patent number: 10301166
    Abstract: 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.

    Abstract: Provided are encased parallel channel adsorbent contactor apparatus and systems and swing adsorption processes related thereto. Encased parallel channel adsorbent contactors are useful in swing adsorption processes. A plurality of the encased adsorbent contactors are loaded and sealed together in a swing adsorption vessel such that substantially an entire feed stream must pass through the channels of the contactors and not through stray gaseous stream paths between contactors.

  • Patent number: 9995259
    Abstract: An evaporated fuel processing device includes a liquid level surface detection valve that detects a full-tank liquid level surface when refueling, and closes a canister communication hole; a fuel shutoff valve to close an evaporation hole when a liquid level surface becomes higher than the full-tank liquid level surface; and an outlet port communicating with a canister. A first communication path and a second communication path are formed in a folded back shape folded back at a first valve seat upper part in plan view. The first communication path enables communication between the first valve seat upper part and a second valve seat upper part, and the second communication path enables communication between the first valve seat upper part and the outlet port. This constitution reduces fuel liquid leakage from the outlet port.

  • Patent number: 9970393
    Abstract: Methods and systems are provided for purging a fuel vapor canister during conditions when purge vacuum is limited, such as during boosted conditions. An exhaust-driven purge pump is used to flow positive pressure air through a canister, and purge the canister to a compressor inlet. The air is heated during the pressurization, improving hydrocarbon desorption from the canister.

  • Patent number: 9945333
    Abstract: Fuel vapor emissions from a fuel tank directed to a canister containing adsorbent are minimized by an intermediate condenser and conduit configuration. Condensing and cooling fuel vapor emissions allows a reduction in canister capacity, where the canister can still meet and accommodate refueling and/or diurnal emissions control requirements. Pressurized and unpressurized fuel tanks for various vehicles, including vehicles with an internal combustion engine and hybrid electric vehicles, can be configured with the present fuel vapor recovery systems.

  • Patent number: 9945330
    Abstract: A method for diagnosing a fuel tank vent valve of a motor vehicle. In the method it is inferred, from a curve of a pressure p over time in a sub-chamber of the motor vehicle after a start-up of an internal combustion engine of the motor vehicle, as to whether the fuel tank vent valve is jammed open. The sub-chamber contains a fuel tank of the motor vehicle and is delimited by the fuel tank vent valve.

  • Patent number: 9890746
    Abstract: A fuel vapor canister is presented, comprising two or more pneumatically coupled concentric adsorbent beds, a vent port configured to deliver fresh air to an outermost concentric adsorbent bed, and a purge port configured to couple an engine intake to an innermost concentric adsorbent bed. The concentric adsorbent beds facilitate improved purging of the canister, thus decreasing bleed emissions. The concentric adsorbent beds may have a bi-conical structure yielding a conical flow path which allows fresh air to flow through the adsorbent beds equally, reducing the size of a canister heel.
