Fuel vapor filter purging of a supercharged internal combustion engine in induction mode

A method for operating an internal combustion engine, the method comprising:

• providing a combustion unit;
• providing a fresh gas tract for supplying fresh gas to the combustion unit, a fresh gas compressor and a differential pressure valve being integrated into the fresh gas tract;
• providing a fuel tank system that comprises a fuel tank, a fuel vapor filter that is fluid-conductively connected to the surroundings, a tank venting line leading from the fuel tank to the fuel vapor filter, a first purge gas line, which leads from the fuel vapor filter to a first section of the fresh gas tract situated downstream from the differential pressure valve as well as upstream from the fresh gas compressor, and a second purge gas line, which leads from the fuel vapor filter to a second section of the fresh gas tract situated downstream from the fresh gas compressor;
• partially closing the differential pressure valve at least temporarily during the intake mode of the internal combustion engine with fuel vapor filter purging;
• and
• introducing purge gas into the first section of the fresh gas tract via the first purge gas line.
