An adsorption element for adsorbing gases and vapors from the gaseous atmosphere in the intake tract of an internal combustion engine. The adsorption element is disposed within a wall of a flow cross section carrying the intake air, has a planar adsorption medium along which the intake air flows, and is pleated to create folds in longitudinal direction of the intake stream.

Adsorption element

An active carbon coated filter element is proposed for preventing the issuance of hydrocarbons from an opening. It includes a medium containing active carbon, which is of substantially planar shape and has a frame. The frame is provided with sealing lips on at least two sides. The medium is arranged with the frame in a plastic holder, the plastic holder being able to be inserted and fixed in the opening. The sealing lips engage the wall of the opening.

Active carbon coated filter element for preventing the leaking of hydrocarbons

An adsorption element for adsorbing gases and vapors from the gas atmosphere in a gas stream in an intake tract of an internal combustion engine, in which the gas atmosphere is present in a flow cross section of the intake tract. The adsorption element has free-flow channels through which the gas stream is passed. The adsorption element includes at least one adsorption layer, and the free-flow channels are formed by at least one spacer element, and the spacer element is arranged between adsorption layers.
