Abstract
Titre : Procédé pour libérer le serrage d’une soupape de dosage électromagnétique Procédé (100) pour libérer le blocage de la soupape de dosage électromagnétique d’un système de dosage pour doser une solution uréique, pour un catalyseur SCR dans le canal des gaz d’échappement d’un moteur à combustion interne. Selon le procédé on sollicite la soupape de dosage par une pression prédéfinie avec la solution uréique (120). Figure 1
