Method for determining buffering effect of activated carbon filter of motor vehicle tank ventilation, involves supplying defined hydrocarbon quantity to activated carbon filter through tank connection of activated carbon filter

摘要

The method involves supplying a defined hydrocarbon quantity (12) to an activated carbon filter (5) through a tank connection (7) of the activated carbon filter using a hydrocarbon feeding device (2). A defined flow rate (13) from the activated carbon filter is suctioned at a suction connection (9) of the activated carbon filter using a hydrocarbon measuring device (3). An independent claim is included for a test stand.
