Abstract

L'invention concerne un procédé de décrassage d'un dépôt d'urée solide d'une ligne d'échappement (1) d'un moteur à combustion interne (2) étant pourvue d'un filtre à particules (52) et d'un système de réduction catalytique sélective (5) comportant un injecteur (6) pour injecter un liquide de dépollution à base d'urée. Pour éliminer le dépôt d'urée solide, ledit procédé comporte une étape de déclenchement d'une phase de décrassage par augmentation d'une température dans ladite ligne d'échappement (1) provoquée par une phase de régénération partielle du filtre à particules, la phase de décrassage étant déclenchée avant que la masse de suies dans ledit filtre (52) ait atteint un seuil de déclenchement d'une régénération dudit filtre (52).
