Abstract

L'invention concerne un appareil de traitement de carburant évaporé qui permet d'effectuer la purge la plus appropriée du carburant évaporé conformément à l'état d'adsorption du carburant évaporé dans un absorbeur de vapeur de carburant ou conformément à tout changement de celui-ci. L'appareil de traitement de carburant évaporé (12) comprend un élément absorbeur de récupération de vapeur de carburant (26) et un élément absorbeur de vapeur de carburant (36), l'élément absorbeur de vapeur de carburant (36) étant pourvu d'un capteur de température (56) pour la détection de la température interne. Sur la base de la détection, par le capteur de température (56), de la température, ou de tout changement de celle-ci, de l'adsorbant (34) dans l'élément absorbeur de vapeur de carburant (36), une commande de purge peut être conduite dans l'élément absorbeur de récupération de vapeur de carburant (26) et l'élément absorbeur de vapeur de carburant (36), par exemple, une purge préférentielle dans l'élément absorbeur de vapeur de carburant (36) lorsque la quantité de carburant évaporé adsorbée dans l'élément absorbeur de vapeur de carburant (36) est importante.
