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.

1. A system, comprising: an induction conduit including an air flow passage in fluidic communication with engine combustion chambers and having a recessed pocket; anda 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 comprising a non-breathable film coupled to the induction conduit, a hydrocarbon adsorption layer interposing the breathable layer and the substrate layer, and where a surface of the substrate layer is contoured to be in face sharing contact with a surface of a housing of the induction conduit. 2. The system of claim 1, where the breathable layer and the substrate layer are coupled along a periphery of the breathable layer and the substrate layer. 3. The system of claim 1, where the hydrocarbon adsorption layer includes a plurality of sections spaced away from one another. 4. The system of claim 3, where the breathable layer and the substrate layer are coupled via a coupling interface extending between at least two of the plurality of sections. 5. The system of claim 1, where the passive-adsorption hydrocarbon trap is spaced away from a bottom of the air flow passage. 6. The system of claim 1, where a cross-sectional area of the air flow passage remains constant transitioning into a section of the induction conduit having the passive-adsorption hydrocarbon trap coupled thereto. 7. The system of claim 1, where the breathable layer and the hydrocarbon adsorption layer are coupled via a coupling interface, the coupling interface comprising one or more of an adhesive bonding interface, a sew stitching interface, and welding interface. 8. The system of claim 1, where the substrate layer is a tray having the hydrocarbon adsorption layer positioned therein. 9. The system of claim 1, where the substrate layer is coupled to a housing of the induction conduit. 10. The system of claim 1, where the breathable layer comprises non-woven polyester. 11. A system, comprising: an airflow induction conduit in fluidic communication with an engine intake and including a recessed pocket; anda passive-adsorption hydrocarbon trap positioned within the recessed pocket, forming a continuous, uninterrupted linear surface without sharp edges, ledges, or shelves, and defining a boundary of an air flow passage where a cross-sectional area of the air flow passage remains constant transitioning into a section of the induction conduit having the passive-adsorption hydrocarbon trap coupled thereto, the passive-adsorption hydrocarbon trap including a hydrocarbon adsorption layer interposing a breathable layer and a substrate layer, the substrate layer coupled to the conduit. 12. The system of claim 11, where the hydrocarbon adsorption layer includes a plurality of sections spaced away from one another, and where the breathable layer and the substrate layer are coupled via a coupling interface extending between at least two of the plurality of sections. 13. The system of claim 12, where the passive-adsorption hydrocarbon trap is spaced at a vertical top portion of the conduit. 14. The system of claim 11, where the substrate layer is a tray having the hydrocarbon adsorption layer positioned therein. 15. An induction system in an engine comprising: an induction conduit including an air flow passage in fluidic communication with at least one combustion chamber in the engine; anda passive-adsorption hydrocarbon trap positioned within the induction conduit and spaced away from a bottom of the induction conduit, the passive-adsorption hydrocarbon trap including a breathable layer and a substrate layer enclosing a hydrocarbon absorption layer, the substrate layer coupled to the induction conduit and being non-breathable and coupled to the breathable layer via a coupling interface extending along a periphery of the substrate layer and the breathable layer, a side of the breathable layer defining a boundary of the air flow passage and where a cross-sectional area of a housing of the induction conduit remains constant in a section of the induction conduit having the passive-adsorption hydrocarbon trap coupled thereto. 16. The inductions system of claim 15, where the hydrocarbon absorption layer includes a first section spaced away from a second section. 17. The induction system of claim 15, where cross-sectional area of the air flow passage remains constant transitioning into a section of the induction conduit having the passive-adsorption hydrocarbon trap coupled thereto.
