摘要： A method for controlling a tank ventilation device (102) for a motor vehicle (100) is proposed in which first of all a tank vent valve (28) of the tank ventilation device (102) is closed. Then, the value of a control signal for the tank vent valve (28) is increased in the sense of an opening of the tank vent valve (28) until a leak detection means (23, 31) associated with the tank ventilation device (102) recognizes a leak in the tank ventilation device (102). The value of the control signal at which the leak in the tank ventilation device (102) is recognized is identified as the opening control value for opening the tank vent valve (28). In this way, the opening control value for the tank vent valve (28) can be determined with a high frequency and precision.

摘要： A tank venting device for a motor vehicle has a fuel tank, a fuel vapor accumulator for storing fuel vapors escaping from the fuel tank and a connection line, via which the fuel vapors may flow from the fuel tank into the fuel vapor accumulator. Furthermore, an overpressure line having an overpressure valve is provided, via which the fuel vapors may flow from the fuel tank into the fuel vapor accumulator when the overpressure valve is open. An attachment of the connection line on the fuel vapor accumulator and an attachment of the overpressure line on the fuel vapor accumulator are situated at different points on the fuel vapor accumulator. The operational reliability of a tank venting procedure may thus be increased and the adsorption capacity of the fuel vapor accumulator may be used better.

摘要： To operate an internal combustion engine subvolumes of the fluid flowing into an intake duct in each instance during a predetermined time period are determined for each period. Tank purging values of a characteristic quantity are determined for each period. The characteristic quantity is representative of a tank purging fuel mass, which flowed through the tank purging valve in each instance during the predetermined time period. The successive subvolumes are added together, starting from the currently determined subvolume, to give a total subvolume, until the total subvolume is greater than or equal to an effective intake duct volume downstream of the tank purging valve.
