Abstract
An activated carbon filter apparatus has a housing with an interior space with an activated carbon filter arranged therein. The activated carbon filter is divided into a first region and a second region. An activated carbon filling is in each region. The two regions are divided into different sections by dividing walls. The sections being filled with activated carbon, and the sections of one region and the two sections at the transition between the first region and the second region are connected fluidically to one another by crossflow regions. A void volume is provided in the first region and/or in the second region below an activated carbon filling of one section to receive desorbed hydrocarbons.
