Abstract: A method may verify that a fuel tank cap is present and properly closed after refueling of a motor vehicle fuel tank. The method may include, in response to a request for refueling: (a1) enabling refueling of the motor vehicle fuel tank by opening a first vent valve connected in series in a vent line, downstream from a first port of a recirculation line coupled to the vent line, so that to vent the motor vehicle fuel tank to the atmosphere through a fuel vapor canister; (b1) disabling refueling of the motor vehicle fuel tank by closing the first vent valve; (c1) monitoring the internal pressure within the motor vehicle fuel tank when the refueling request is finished; and (d1) concluding that the fuel tank cap is deemed present and properly closed when the internal pressure increases and/or remains higher than the atmospheric pressure.

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.

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.
