Abstract: A space-saving broadband resonator configured to install within and utilize inner space of other components and includes a resonator insert having a tubular pipe elongated along a central axis, the tubular pipe having a circumferential outer wall having a plurality of perforation holes spaced apart and extending radially through the circumferential outer wall. An interior of the tubular pipe forms a gas flow duct. A plurality of annular disk-shaped walls provided on and projecting radially outwardly from the tubular pipe. Adjacent annular disk-shaped walls spaced axially part from each other define resonator chambers therebetween. A bell mouth is formed at the second axial end of the tubular pipe, the bell mouth flared radially outwardly.

Abstract: An air intake tract with a hydrocarbon adsorber is provided for adsorbing hydrocarbons of a motor vehicle. The hydrocarbon adsorber includes at least one first layer constructed of a hydrocarbon adsorbing material. Optionally, one or more stacked layers are provided including at least an uppermost layer and at least one intermediate layer. The at least one first layer includes a solid shape within an outer boundary and is adapted for sonic welding onto an interior of the air intake tract. The uppermost layer and any intermediate layers include an opening such that the uppermost layer provides access for a sonic welding tool from an upper side of the subassembly to the at least one first layer through the opening.

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.
