Relief valve and fuel vapor valve assembly

Номер: US20120024265A1
Автор: Robert Dean Keller
Принадлежит: Eaton Corp

A valve assembly is provided that can perform an overpressure relief function to vent fluid from a first component, such as to vent fuel vapor from a fuel tank, to a second component, such as a carbon canister, without being affected by the vapor pressure in the vent line to the second component. That is, the valve opens to provide pressure relief when needed regardless of the vapor pressure against which it opens. The valve assembly may also include a solenoid that is controllable to allow fluid flow separately from the movement in response to vapor pressure.

Methods and systems are provided for purging a fuel vapor storage canister in an evaporative emissions system of a vehicle. In one example, a method may include generating vacuum in a fuel tank fluidically coupled to the fuel vapor storage canister during an auto-stop of an engine while the engine spins down to rest, and purging vapors to an intake manifold of the engine during a subsequent restart of the engine. In this way, the fuel tank may be held at a vacuum while the engine is off, enabling more efficient purging of the fuel vapor storage canister when the engine is restarted.

Evaporative fuel treatment device

In an evaporative fuel treatment device, a differential pressure specifying unit specifies a differential pressure between a pressure in a diagnosis target system and the atmosphere, and a pressure target setting unit sets a pressure target value so that the differential pressure attains a predetermined differential pressure value. A pump pressurizes or depressurizes the pressure in the diagnosis target system to the pressure target value, and a leakage diagnosis unit performs a leakage diagnosis based on a pressure change relation value related to the pressure change in the diagnosis target system and the leakage diagnosis threshold value. The fuel partial pressure estimation unit estimates a first partial pressure of fuel vapor in the fuel tank from a tank inside concentration and a tank absolute pressure of a specific component. A corresponding partial pressure specifying unit specifies a second partial pressure of the fuel vapor in the fuel tank based on a relation between the tank absolute pressure and the first partial pressure when the second partial pressure of the fuel vapor in the fuel tank when the pressure is increased or reduced to the target pressure value. A comparison unit compares the first partial pressure and the second partial pressure. A correction unit corrects, based on a comparison result of the comparison unit, a leakage diagnosis threshold value or the pressure change relation value used for the leakage diagnosis.

Methods and systems are provided for preventing fuel tank overfilling during refueling events, wherein overfilling of the fuel tank is prevented by delivering a pressure pulse to the fuel tank responsive to a fuel fill level reaching a predetermined threshold, or responsive to an attempt to add additional fuel subsequent to the fuel fill threshold being reached. In one example, an onboard pressure vessel is actively pressurized via an onboard pump, where the pressure may be actively released and routed to the fuel tank to induce an automatic shutoff of a refueling dispenser pump under predetermined conditions. In this way, automatic shutoffs of refueling dispenser pumps may be rapidly and reliably induced, thus preventing fuel tank overfilling, prolonging the lifetime of fuel vapor storage canisters, and reducing undesired evaporative emissions. 1. A method comprising:storing pressure in a vessel external to a fuel tank that supplies fuel to a vehicle engine; and selectively coupling the vessel to the fuel tank to pressurize the fuel tank to a predetermined pressure threshold responsive to an indication that a fuel level in the fuel tank has reached a predetermined fuel fill level during a refueling event.2.

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. A controller may be used to determine a particular operational condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture.
