Abstract:
1. An air induction system for an internal combustion engine of a motor vehicle, said system comprising: an unfiltered air intake, an air cleaner assembly, a filtered air duct, a mass air flow sensor arranged along said filtered air duct for measuring air flow through said air induction system; a throttle body arranged to regulate air flow through said air induction system, and a hydrocarbon adsorber positioned in said air induction system for absorbing uncombusted hydrocarbons; wherein said hydrocarbon adsorber is positioned out of the main airflow that passes through the air induction system, and said air induction system further comprises a purge channel for directing a portion of the air flow through the air induction system through said hydrocarbon adsorber to purge adsorbed hydrocarbons from said adsorber, wherein said air cleaner assembly comprises wherein said hydrocarbon adsorber is disposed in a recess in a wall of one of the air filter housing members downstream of the air filter element.
