摘要：The tank venting device has a fuel vapor reservoir connected to a fuel tank todeliver escaping fuel vapors to the fuel vapor reservoir, and is connected to the internal

combustion engine in such a manner that during a tank venting operation the fuel vaporscontained in the fuel vapor reservoir are delivered as regeneration gas. To check theoperability of the venting device the fuel concentration in the regeneration gas isascertained at a minimum of two different points in time during the venting operation.The fuel concentration values in the regeneration gas are compared with respectivereference values representing the regeneration gas fuel concentration in the situation inwhich no additional fuel vapors are delivered during the venting operation. Theassessment of the venting device operability is carried out by comparison of the valuesascertained for the fuel concentration in the regeneration gas with the reference values.
