Abstract: An evaporative emissions control system for reducing the amount of fuel vapor emitted from a vehicle includes a canister containing a sorbent material and a cartridge heater disposed at least partially within the canister in direct contact with the sorbent material. Electrical terminals for applying power to a heating element within the heater are disposed external to the canister. At least one heat sink may be included within the canister in direct contact with the heater. A method of manufacturing an evaporative emission control system that includes a cartridge heater disposed in a canister is also presented.

Abstract: Disclosed herein an evaporative emission treatment device comprising: a housing; and an adsorption member disposed in the housing, the adsorption member comprising an adsorption component comprising an activated carbon textile made from a novoloid precursor.

Abstract: An emissions control canister including an insert tube and a final scrubber inside the tube. Because a scrubber formed as a carbon monolith is relatively fragile and easily damaged, a flexible, porous, resilient sling is provided for installing and retaining scrubber within cylindrical tube in lieu of either seals or elastomeric gaskets. An end of the scrubber is placed on a center portion of the sling, and the straps are folded alongside the cylindrical surface of the scrubber to form a sub-assembly. The sling is die-cut from planar stock of either a loose, thick, woven polyester fabric or an open-cell resilient foam. Advantages of the sling over a resilient elastomeric gasket are cost, ease of assembly, and the outer surface of the scrubber is made available as additional vapor adsorption area.

Abstract: A hydrocarbon emissions scrubber for use in an evaporative emissions control system of a motor vehicle includes a scrubber element having an elongate body. The body defines a plurality of passageways for the flow of fluid therethrough. The plurality of passageways are one of coated with or constructed of a sorbent material. The sorbent material is adsorptive of hydrocarbons.

Abstract: An emissions control canister including an insert having an elongate well and flange. The insert extends into a chamber such that a carbon adsorption column is a hollow cylinder around the insert. After vapors flow through the column of adsorbent, flow is directed through holes in the flange and out through an atmosphere port. The flow path through the hollow cylinder has an increased L/D ratio and improves emission performance. In a second embodiment, a cylindrical tube surrounds the exit port and extends into the insert, forcing vapor flow along a tortuous path between the cylindrical wall and the insert. In a third embodiment, a final scrubber is added inside the tube.

Abstract: A valve assembly for a vapor canister includes a partition adapted to be disposed in an interior chamber of the vapor canister and having at least one opening extending therethrough. The valve assembly also includes a valve connected to the partition and covering the at least one opening and being movable to provide variable flow of fluid therethrough.
