Abstract

L’invention concerne un procédé pour détecter une anomalie dans un système de circuit d’air dans un moteur à combustion interne, le circuit d'air comprenant une conduite d'arrivée (11), une pompe à air (2), une conduite intermédiaire (12) avec un capteur de pression et température (4) agencé sur la conduite intermédiaire, une électrovanne d'arrêt (3), une conduite de soufflage (13) délivrant de l'air sur une grille chauffante (5) pour chauffer un pot catalyseur (55), le procédé comprenant des étapes de vérification de divers paramètres liés à la pompe, des étapes de détection de fuites dans la conduite intermédiaire et dans la conduite de soufflage et une identification d’un composant possiblement en anomalie. Figure 2The invention relates to a method for detecting an anomaly in an air circuit system in an internal combustion engine, the air circuit comprising an inlet pipe (11), an air pump (2), an intermediate pipe (12) with a pressure and temperature sensor (4) arranged on the intermediate pipe, a shut-off solenoid valve (3), a blowing pipe (13) delivering air to a heating grid (5) for heating a catalyst pot (55), the method comprising steps of checking various parameters related to the pump, steps of detecting leaks in the intermediate pipe and in the blowing pipe and identifying a possibly anomalous component.
