Abstract: A method for controlling a filling operation of a vehicular liquid storage system including a tank including a fill level limiting valve. The method includes: detecting start of a first filling event; measuring a first fill level of the tank; verifying whether the measured first fill level has reached a predetermined fill level; if the verifying is positive, starting a first timer for a first amount of time; upon expiry of the first timer, closing the fill level limiting valve.

Abstract: It is proposed a method for determining the volatility of fuel in a fuel storage system, the method comprising: determining that a refueling event has occurred (210) and that the fuel storage system has subsequently been sealed (220); performing a first pressure measurement (230) at a first time after the determining; performing a second pressure measurement (240) at a second time, the second time occurring after the first time; determining a pressure evolution rate (250) from the first pressure measurement at the first time and the second pressure measurement at the second time; and deriving an estimation (260) of the volatility of the fuel from the pressure evolution rate.

Abstract: A vapour recovery system recovers vapour coming from a vehicle tank. The system includes a valve that is positionable in a closed position, an open position creating a passageway with a first size, and one or more intermediate positions each creating a passageway with a size smaller than the first size. The system also includes an electronic controller to control an actuator to position the valve in a sequence of positions over time. The sequence includes at least one of the intermediate positions during a time period larger than 1 second. The valve is arranged in a line of the vapour recovery system between a vapour outlet of the vehicle tank and the atmosphere. The actuator is a stepper-motor based linear actuator. The controlling includes selecting at least one intermediate position, and the selection includes selecting a number of steps to be set from a predetermined reference position.

Abstract: A vehicle storage system with vapor control. The storage system includes: a vehicle tank including a vapor outlet, a filter unit including a filter inlet and outlet, a housing including a first port communicating with the vapor outlet, a second port communicating with the filter inlet, a third port communicating with the filter outlet, and a fourth port. A closure body is moveably arranged in the housing, the closure body configured to: close the third and fourth ports in a first position of the closure body, create in the housing a barrier between a first volume and a second volume in a second position of the closure body, the first volume forming a passage between the first and second ports, and the second volume forming a passage between the third and fourth ports, and close the first and second ports in a third position of the closure body.

Abstract: A valve, controlling pressure differential by regulating fluid flow between a tank and a canister, includes: a valve opening; a first moving element carrying a first sealing device making a leaktight seal and movable relative to the valve opening between a closed and an opened position allowing a first flow between the tank and the canister, through a first passageway with a first size; a second moving element carrying a second sealing device making a leaktight seal and movable relative to the valve opening between a closed and an opened position allowing a second flow between the tank and the canister, through a second passageway with a second size. The second moving element includes a central hole having a frustoconical surface partly defining the first passageway. The first sealing device has a complementary frustoconical surface cooperating with the frustoconical surface of the central hole of the second moving element.

Abstract: A vehicular liquid containment system including a tank, a pressure sensor arranged to detect a pressure in a vapor dome inside the tank, at least two thermistors configured to detect temperatures at a plurality of levels of the tank, and leak detection logic operatively connected to the pressure sensor and the thermistors. The leak detection logic is configured to: use a first thermistor of the thermistors to perform a first measurement indicative of a temperature in the vapor dome in the tank; estimate an expected pressure evolution in function of at least the first temperature measurement; monitor pressure sensed by the pressure sensor, determine whether the monitored pressure deviates from the expected pressure evolution, and generate a leak condition signal conditional on the determining.
