Abstract
A hydrocarbon adsorbing device capable of adsorbing or absorbing and subsequently releasing hydrocarbons in the induction system of a motor vehicle. In one embodiment, the hydrocarbon adsorbing device includes an inner cylinder of hydrocarbon adsorbing material and an outer cylinder of hydrocarbon adsorbing material. The inner cylinder is located within the outer cylinder. The hydrocarbon adsorbing device also includes an intermediate member of hydrocarbon adsorbing material that is located between the inner cylinder and the outer cylinder. The intermediate member may be attached to both the outer cylinder and the inner cylinder and be folded in a pleated fashion. In one embodiment, the intermediate member extends completely about the inner cylinder. The hydrocarbon adsorbing device may also include a flange attached to and extending outwardly from the outer cylinder for use in locating the hydrocarbon adsorbing device in the induction system.
