Abstract: An evaporative emissions control system configured to recapture and recycle emitted fuel vapor on a vehicle fuel tank is provided. The control system includes a first and second vent tube disposed in the fuel tank, a first and second vent valve, a vent shut-off assembly, a purge canister and a control module. The vent shut-off assembly selectively opens and closes the first and second valves to provide overpressure and vacuum relief for the fuel tank. The control module regulates operation of the vent shut-off assembly based on operating conditions to vent the first and second vent valves to the purge canister. The vehicle fuel tank comprises a saddle tank having first and second lobes and a raised portion arranged generally at a top portion of the fuel tank. The first vent valve is arranged generally in the first lobe and the second vent valve is arranged in the raised portion.

Abstract: A valve apparatus for use in a liquid tank, includes a casing, an extractor, and a float. The casing defines a main chamber, the main chamber having an inlet orifice and at least one outlet orifice. The extractor includes at least one wall member extending substantially across the main chamber and being adapted for extracting droplets present in a vapour stream coming from the liquid tank and entering the main chamber via the inlet orifice. The float includes a closure element capable of closing off the outlet orifice(s), the float being slidably mounted along the at least one wall member.

Abstract: An evaporated fuel treating device includes: a canister configured to adsorb evaporated fuel generated in a fuel tank through a vapor passage; a blocking valve configured to close and open the vapor passage, the blocking valve having a stepping motor as a drive source; and a controller configured to operate the blocking valve by controlling electric power that is supplied from a predetermined power supply to the blocking valve. The controller is configured, when there is a request to drive the blocking valve, to operate the blocking valve by controlling the electric power such that when a voltage that is supplied from the power supply to the blocking valve is less than a predetermined value, a driving period which is an interval between pulses that are supplied to the stepping motor becomes long compared to when the voltage is equal to or higher than the predetermined value.

Abstract: Methods and systems are provided for detecting leaks in an engine fuel system coupled in a vehicle including a first fuel tank and a second fuel tank, and a canister coupled together via a three-way valve. A leak test may be initially performed on the first fuel tank by supplying vacuum to the first fuel tank. The second fuel tank may be tested for leaks immediately following the leak test on the first fuel tank by recycling vacuum from the first fuel tank.
