Abstract

Procédé de détection de fuites d’une valve de régulation (32) de la pression du carter d’un moteur thermique (10), ce moteur comportant une tubulure d’admission (22) dans des cylindres (4) disposée en aval d’un papillon de contrôle du passage des gaz (20), équipée d’un capteur de pression et de température (24), le procédé comportant une étape de calcul du débit d’air estimé donné par le réglage du papillon, et du débit d’air estimé donné par le capteur de pression et de température, puis une étape de comparaison du rapport de ces débits estimés avec un seuil de détection qui détecte au-dessus de ce seuil la présence d’une fuite de la valve de régulation (32).
