Abstract

L'invention propose un procédé de détection d'un bouchon dans une conduite d'alimentation en urée liquide d'un dispositif de réduction catalytique sélective, la conduite d'alimentation étant munie d'un injecteur et d'un capteur de pression dans la conduite d'alimentation, le procédé comportant les étapes consistant en : - l'ouverture (54) de l'injecteur pendant un temps prédéterminé ; - la détection (50, 52) d'une pression dans la conduite d'alimentation supérieure à une valeur de pression seuil (48) ; - la comparaison (66) de l'intervalle de temps séparant l'ouverture de l'injecteur de la détection de la pression supérieure à la valeur de pression seuil (48) avec une durée seuil (60) ; - la détection (68) d'un bouchon quand l'intervalle de temps est inférieur à la durée seuil (60).
