Abstract: Methods and systems are presented for combining two or more common fuel vapor storage canisters to increase storage volume for fuel vapors of a vehicle. In one example, a fuel vapor manifold is constructed to permit communication between ports of carbon filled fuel vapor storage canisters. The fuel vapor manifold is a clam shell design that permits vibration welding.

Abstract: An air distribution plenum for controlling air flow in a vehicle HVAC system includes an air inlet and first and second air outlets. A movable member substantially blocks the first and second air outlets when in a first position, blocks only the first air outlet in a second position, blocks only the second air outlet in a third position, and permits air to flow through both the first and second air outlets when in a fourth position.

Abstract: Methods and systems are provided for a vapor canister couple to a fuel tank of a vehicle. A series of fluidically coupled, variable capacity bleed elements, externally coupled to a sidewall of the vapor canister, capture the bleed emissions resulting from desorption of fuel vapors from an adsorbent material inside the vapor canister. The series of bleed elements may be fluidically coupled through flow paths passing through the vapor canister wall, connecting through a first flow path to a chamber inside the vapor canister and connecting through a second flow path to a vent port of the vapor canister.
