Hydrocarbon adsorbing device for adsorbing backflow of hydrocarbons from a vehicle engine

摘要

The present invention involves an air induction system having a hydrocarbon adsorbing feature for adsorbing backflow of hydrocarbons from a vehicle engine. The air induction system includes an air filter for filtering ambient air, a clean air duct in fluid communication with the air filter, sensor mounted adjacent the clean air duct, and a hydrocarbon adsorber mounted to the clean air duct for adsorbing backflow of hydrocarbons from the engine. The hydrocarbon adsorber includes an outer body having an air inlet end and an air outlet end. The body is comprised of hydrocarbon adsorbing material and has a configuration of connected inner walls disposed therein and spaced apart from each other.
