Abstract

Dispositif (10) de purge des vapeurs d’un carburant stocké dans un réservoir (30) d’un véhicule (1) automobile thermique, comprenant un module de contrôle (130) configuré notamment pour déterminer la contribution de la convection du flux de gaz à la température dudit flux de gaz à partir d’une mesure de température du flux de gaz reçue et d’une mesure de température interne de la pompe reçue, pour déterminer la contribution de la conduction du flux à la température du flux de gaz à partir du débit massique du flux, d’une température du flux de gaz reçue et d’une mesure de température interne de la pompe reçue, pour estimer la température du flux de gaz circulant dans un circuit de purge (120) à partir des contributions de compression adiabatique, de convection et de conduction déterminées, pour calculer la concentration en vapeurs de carburant du flux à partir de la température estimée. Figure pour l’abrégé : Fig. 1
