Abstract
A subassembly for adsorbing hydrocarbons with an air intake system of a motor vehicle is provided. The subassembly includes a plurality of stacked layers constructed of a hydrocarbon adsorbing material. The plurality of stacked layers includes at least one lowermost layer and an uppermost layer. The at least one lowermost layer includes a solid shape within an outer boundary. The at least one lowermost layer is adapted for attachment to a component of the air intake system. The uppermost layer includes an opening such that the uppermost layer provides access from an upper side of the subassembly to the at least one lowermost layer through the opening for attaching the subassembly to the component.
Claims17
A subassembly for adsorbing hydrocarbons with an air intake system of a motor vehicle, the subassembly comprising:
- a plurality of stacked layers constructed of a hydrocarbon adsorbing material, the plurality of stacked layers including at least one lowermost layer having a solid shape within an outer boundary, the at least one lowermost layer adapted for attachment to a component of the air intake system, the plurality of stacked layers further including an uppermost layer, the uppermost layer having an opening such that the uppermost layer provides access from an upper side of the subassembly to the at least one lowermost layer through the opening for attaching the subassembly to the component.
A component for an air intake system of a motor vehicle, the component comprising:
- a housing including an input port for receiving a source of intake air and an output port in fluid communication with an engine of the motor vehicle;
- and
- a subassembly for adsorbing hydrocarbons, the subassembly including a plurality of stacked layers constructed of a hydrocarbon adsorbing material, the plurality of stacked layers including at least one lowermost layer having a solid shape within an outer boundary, the at least one lowermost layer adapted for attachment to the housing, the plurality of stacked layers further including an uppermost layer defining an opening such that the uppermost layer provides access from an upper side of the subassembly to the at least one lowermost layer through the opening for attaching the subassembly to the housing.
