  "textContent": "A method for operating an internal combustion engine, which includes at least a combustion engine, a fresh gas line and a fuel tank system. The fuel tank system includes a fuel tank, a fuel vapor filter, a purge gas line that connects the fuel vapor filter to the fresh gas line, and a sensor that is suited for determining a degree of hydrocarbon saturation of purge gas contained in the purge gas line. The fuel tank system also has a tank ventilation valve that is integrated in the purge gas line and/or a purge-gas feed device. In response to a control device, a tank ventilation process is initiated, as needed, for which the purge-gas feed device is operated, and/or the tank ventilation valve is opened; for the tank ventilation process, a hydrocarbon content of the purge gas being ascertained using the sensor. A quantity of fuel to be introduced into at least a combustion chamber of the combustion engine is then adjusted as a function of the ascertained hydrocarbon content. The hydrocarbon content is thereby continuously determined during the tank ventilation process and is utilized to actuate the tank ventilation valve and/or the purge-gas feed device.",
