Abstract
An air induction system of an automotive internal combustion engine comprises an evaporative emission control device inserted into an air intake tube connecting an air cleaner canister and an intake manifold of the engine. The evaporative emission control device comprises a rigid tubular body that includes an upstream end and a downstream end. A hydrocarbon vapor absorbing element is disposed within the rigid tubular body such that the upstream face is recessed from the upstream end of the rigid tubular body, and the downstream face is recessed from the downstream end of the rigid tubular body. The extended ends of the rigid tubular body thereby protect the recessed faces from incidental contact. The air intake tube is formed of elastomeric material that provides flexible support for the evaporative emission control device to protect against damage due to vibration.
