Abstract
An air cleaner assembly and an air induction system for an internal combustion engine. The air cleaner assembly preferably is formed using first and second housing members that are assembled to define an interior volume. A hydrocarbon adsorber is located within air induction system, e.g., within the interior volume of the air cleaner assembly. The hydrocarbon adsorber is positioned outside of the main air flow within a recess formed in a wall of one of the housing members. A purge channel is formed in the interior wall that houses the hydrocarbon adsorber. Air flow through the air induction system passes via the purge channel through the hydrocarbon adsorber. By facilitating air flow through the hydrocarbon adsorber that is positioned outside of the main airflow, the hydrocarbon adsorber is self-regenerating and does not have to be replaced over the lifetime of the vehicle as a result of hydrocarbon build-up.
