Motor vehicle comprising an activated carbon filter and method for regenerating an activated carbon filter

Abstract

1. Motor vehicle having an activated carbon filter and method for regenerating an activated carbon filter. 2. A motor vehicle (1) is proposed, comprising an, in particular, direct-injection internal combustion engine (2), a fuel tank (3) and an aeration device (4) for the fuel tank that comprises an activated carbon filter (5) and a regeneration device (6) for regenerating the activated carbon filter, and a method for regenerating an activated carbon filter in a motor vehicle comprising an, in particular, direct-injection internal combustion engine. 2.2. According to the invention, a regeneration device (6) is provided in the motor vehicle and is assigned a control device (7) which undertakes an activation of the regeneration device (6) in the overrun mode of the internal combustion engine (2); for the method, provision is made for an overrun mode of the internal combustion engine to be detected in one method step and for a regeneration device which is assigned to the activated carbon filter and is intended for purging the activated carbon filter with fresh air to be activated in a subsequent method step. 2.3. To be used in motor vehicles, in particular passenger vehicles.
