Title (EN) METHOD AND DEVICE FOR REGENERATING THE PARTICLE FILTER OF A DIESEL-TYPE INTERNAL COMBUSTION ENGINE DURING THE IDLING PHASES
(FR) PROCEDE ET DISPOSITIF DE REGENERATION DU FILTRE A PARTICULES D'UN MOTEUR A COMBUSTION INTERNE DU TYPE DIESEL, PENDANT LES PHASES DE RALENTI
Abstract: front page image
(EN)The invention relates to a method for regenerating a particle filter on the exhaust line of an internal combustion engine, in which fuel is injected into the exhaust line upstream of an oxidation catalyst which is disposed upstream of the particle filter. The invention is characterised in that, during the idling phases of the internal combustion engine, the temperature at the entrance to the oxidation catalyst is increased in order to prevent the condensation of the fuel.
(FR)Une procédé de régénération du filtre (1) à particules placé sur la ligne d'échappement d'un moteur à combustion interne, dans lequel, pendant la régénération du filtre à particules, du carburant (15) est injecté dans la ligne d'échappement en amont d'un catalyseur d'oxydation (4) disposé en amont du filtre à particules, et pendant les phases de ralenti du moteur à combustion interne, et en cas de régénération du filtre à porticules on augmente la température à l'entrée du catalyseur d'oxydation pour éviter la condensation du carburant.
