Abstract
The invention relates to a method of determining the retention capacity of fuel vapor filters for motor vehicles, wherein a temperature profile of the fuel is recorded on a motor vehicle in a SHED chamber during a temperature cycle. A fuel vapor volumetric flow for a temperature change is calculated from the temperature profile. In a measurement arrangement () fuel is evaporated by means of an evaporator () and is output by means of a charging pump () to a fuel vapor filter () disposed in an oven (). The bleed emissions of the fuel vapor filter () are measured at least during the charging.
