Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a method for producing shaped, activated charcoal. According to the method, after being ground, carbon-bearing material, or a mixture of several carbon-bearing materials are rendered homogenous with a binding agent which contains water, or a mixture of several binding agents, at least one of which contains water. The mixture of carbon-bearing material and binding agent is then formed into shaped bodies. According to the invention, in order to consolidate the grain formation, these are dried until they exhibit a maximum total water content of 3% by wt. in relation to the shaped body. The shaped bodies which have been formed and dried in this manner are then subjected to a carbonization and subsequently a gas activation process.
