Abstract
A tank venting system for an internal combustion engine includes a tank, which is connected via a tank vent to a sorption reservoir for a temporary storage of fuel from a tank venting flow. A purge air pump is provided for feeding regenerated fuel from the sorption reservoir via a purge air flow into an intake air flow to the internal combustion engine. A controller is configured to control the purge air pump in such a way that the purge air flow can be adjusted with regard to its pressure, its mass and/or its volume, thus ensuring that a metering of the regenerated fuel via the purge air flow into the intake air flow takes place in accordance with an operating state of the internal combustion engine. A method for regenerating a sorption reservoir is also provided.
