ABSTRACT:
To operate an internal combustion engine subvolumes of the fluid flowing into an intake duct in each instance during a predetermined time period are determined for each period. Tank purging values of a characteristic quantity are determined for each period. The characteristic quantity is representative of a tank purging fuel mass, which flowed through the tank purging valve in each instance during the predetermined time period. The successive subvolumes are added together, starting from the currently determined subvolume, to give a total subvolume, until the total subvolume is greater than or equal to an effective intake duct volume downstream of the tank purging valve.
