Abstract
A system provides reliable tank ventilation, particularly in the case of supercharged internal combustion engines, while also assuring efficient operation of the internal combustion engine. A tank is connected with an adsorption filter by way of a first tank ventilation line. The adsorption filter is connected with the intake line of the internal combustion engine by way of a second tank ventilation line. A drive apparatus includes a turbine wheel and a pump wheel coupled with one another. The pump wheel is disposed in the second tank ventilation line. The turbine wheel is disposed in a bridging line branching off from the intake line and flowing into the intake line. The bridging line branches off from the intake line downstream from a compressor disposed in the intake line.
