Abstract

Bei einem Verfahren und einer Vorrichtung zum emissionsüberwachenden Betrieb eines ein flüchtiges Medium bevorratenden Vorratsbehältnisses, insbesondere eines Kraftstoffvorratstanks eines Kraftfahrzeuges, wobei zeitweilig eine Dichtheitsprüfung des Vorratsbehältnisses durchgeführt wird, ist erfindungsgemäß vorgesehen, dass die Temperatur des Mediums anhand wenigstens einer Kenngröße, insbesondere der Umgebungstemperatur, mittels einer Modellrechnung zeitweilig oder zyklisch ermittelt wird und entweder als Korrekturgröße bei der Dichtheitsprüfung einbezogen wird oder die Dichtheitsprüfung nur dann durchgeführt wird, wenn die ermittelte Temperatur des Mediums innerhalb eines vorgebbaren Temperaturintervalls liegt.

Figure 00000001
In a method and a device for emission-monitoring operation of a volatile medium-storing storage container, in particular a fuel storage tank of a motor vehicle, wherein temporarily a leak test of the storage container is carried out, the invention provides that the temperature of the medium based on at least one parameter, in particular the ambient temperature, means a model calculation is determined temporarily or cyclically and is either included as a correction variable in the leak test or the leak test is carried out only if the determined temperature of the medium is within a predeterminable temperature interval.
