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.
