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

#CMT# #/CMT# 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). #CMT# : #/CMT# An independent claim is included for a test stand. #CMT#USE : #/CMT# Method for determining a buffering effect of an activated carbon filter of a motor vehicle tank ventilation. #CMT#ADVANTAGE : #/CMT# The method involves supplying a defined hydrocarbon quantity to an activated carbon filter through a tank connection of the activated carbon filter using a hydrocarbon feeding device, and hence enables to obtain a reference value to compare the buffering effects of different activated carbon filters with an absolute value. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a test stand. 2 : Hydrocarbon feeding device 3 : Hydrocarbon measuring device 5 : Activated carbon filter 7 : Tank connection 9 : Suction connection 12 : Hydrocarbon quantity 13 : Flow rate.
