System for storing fuel vapors leaking from fuel tank of motor vehicle through vent pipe, has two functionally separated fuel vapor storages, particularly activate carbon filters

摘要

The system has two functionally separated fuel vapor storages (1,2), particularly activate carbon filters, which are discharged by a scavenging airflow guided into a backwash line (4). A heating device (2.2) is assigned to active carbon filters for accelerating the discharging and fuel vapor storage is connected with the vent pipe of the fuel tank.
