An internal combustion engine having a fuel tank, a fuel vapor store for storing fuel vapors that escape from the fuel tank, having a connecting line between the fuel vapor store and an air intake tract to conduct fuel vapors from the fuel vapor store into the air intake tract during a regeneration phase, a valve arranged in the connecting line, an aeration line for the fuel vapor store, and having a valve arranged in the aeration line for controlling the aeration of the fuel vapor store. A purge air pump arranged in the aeration line is integrated into the valve unit for controlling the aeration of the fuel vapor store. Effective purging or regeneration of the fuel vapor store is attained even when no negative pressure or only a low negative pressure is provided by the air intake tract.
