Abstract
A device and a method for operating an internal combustion engine having at least one cylinder and a tank ventilation system with a line designed to provide pneumatic communication between the tank ventilation system and the at least one cylinder. The line has at least one sensor for determining a hydrocarbon content of a gas flow. A determination, as a function of a measurement signal from the sensor, of a hydrocarbon content of a gas flow flowing from the tank ventilation system to the at least one cylinder is performed. At least one characteristic variable for a fuel quantity to be metered is determined as a function of the determined hydrocarbon content. A metering of fuel into the cylinder is determined as a function of the at least one determined characteristic variable.
