Abstract: A hydrocarbon trap assembly for use in an intake system of a motor vehicle engine includes a first duct having an interior recess adjacent an end thereof, the recess having a blind end; a second duct overlapping the first duct's end and closing off a second end of the recess; and a thermoformed hydrocarbon-adsorbing sleeve inside the recess and having a first edge adjacent the blind end and a second edge adjacent the second end of the recess. One or both ends of the sleeve may engage a hook formed on the respective first and/or second ducts. The second end of the sleeve may have a flange that fits into a gap between the ducts.

Abstract: A hydrocarbon (HC) trap positioned in an intake conduit of an engine is provided. The HC trap includes a stack of consecutively layered polymeric sheets with at least a portion of the sheets impregnated with a HC vapor adsorption/desorption material, the stack of sheets extending from a first exterior surface to a second exterior surface.

Abstract: An induction system in an engine is provided. The air induction system includes an induction conduit including an air flow passage in fluidic communication at least one combustion chamber in the engine and a passive-adsorption hydrocarbon trap positioned within the induction conduit, a portion of the passive-adsorption hydrocarbon trap defining a boundary of the air flow passage, the passive-adsorption hydrocarbon trap including a breathable layer coupled to a substrate layer coupled to the induction conduit, a hydrocarbon adsorption layer interposing the breathable layer and the substrate layer.

Abstract: Devices, systems and methods are provided for adsorbing hydrocarbons from the air intake system of an internal combustion engine. The devices, systems and methods include a hydrocarbon absorbent material, and a structural element configured to hold the hydrocarbon absorbent material within a clean air tube of an internal combustion engine.

Abstract: A clampless tube connection is disclosed, wherein at least one of a conduit and a tube has integrated sealing and locking features.

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.
