Beschreibung
Zusammenfassung:	The system has a cooling circuit for cooling an internal combustion engine by circulation of cooling liquid. An adsorber container (1) includes an adsorbent material (3) e.g. active carbon, to adsorb and desorb fuel vapor. The container comprises a heat exchanger (13) in thermal contact with the adsorbent material. The heat exchanger is mounted on a derivation loop i.e. secondary duct, quilted on the cooling circuit. The adsorbent material is mounted in a casing (2) that includes a fuel vapor inlet (4) and a fuel vapor outlet (5) in communication with the material. An independent claim is also included for a method for purging an adsorber container of fuel vapor issued from a fuel tank of a hybrid car. La présente invention concerne un système 14 pour adsorber et désorber les vapeurs de carburant issues du réservoir de carburant d'un véhicule automobile, notamment hybride, équipé d'un moteur à combustion interne 15. Le système 14 comportant un circuit de refroidissement du moteur à combustion interne 15 par circulation d'un liquide de refroidissement, et un récipient adsorbeur 1 comportant un matériau adsorbant 3 apte à adsorber et désorber les vapeurs de carburant. Le récipient adsorbeur 3 comporte également un échangeur thermique 13 en contact thermique avec le matériau adsorbant 3, l'échangeur thermique étant monté sur une boucle de dérivation piquée sur le circuit de refroidissement. L'invention concerne également un procédé de purge d'un tel récipient adsorbeur 1.
