Abstract

L’invention concerne un système de détection de colmatage d’un clapet antiretour aval (V2) d’un moteur thermique de véhicule automobile. Le moteur thermique comprend :- une valve de régulation de pression (RV) dans un déshuileur (D) d’une culasse (C2) ;- un clapet antiretour de culasse (V1) disposé dans le déshuileur (D) en amont d’une culasse (C2), au niveau d’un retour interne vers un tube d’admission (TA),- le clapet antiretour aval (V2) connecté à une ligne secondaire de ventilation des gaz (LG) issue de la culasse (C2), ici intégré au raccord entrée compresseur. Selon l’invention, le système de détection comprend :- un premier et un deuxième capteurs de pression absolue (AP1, AP2) respectivement pour l’amont du carter (C1) et la culasse (C2), et - un capteur de pression atmosphérique P0. Le diagnostic de blocage est fait sur la base des pressions des capteurs (AP1, AP2), et de la pression atmosphérique. L’invention concerne également un procédé et véhicule sur la base d’un tel système. Figure 1
