Abstract (en)
[origin: WO2012049219A1] The tank ventilation system (100) has an adsorption vessel (10), a regeneration duct (50) and a pump (30). The adsorption vessel (10) serves for capturing and temporarily storing fuel vapors emerging from a fuel tank (20), wherein a purge air flow can flow through the adsorption vessel (10). The regeneration duct (50) connects the adsorption vessel (10) to an intake duct (60). In the regeneration duct (50) there is arranged a pump (30) which is designed to suck the purge air out of the adsorption vessel (10) and admix said purge air to intake air in the intake duct (60). A density of the purge air which flows in the regeneration duct (50) is determined. Furthermore, a purge air mass flow (M) flowing in the regeneration duct (50) is determined as a function of the density of the purge air and a predefined pump characteristic of the pump (30).
