Title
(DE) VORRICHTUNG ZUR DURCHFÜHRUNG EINES REGENERATIONSVORGANGS IN EINEM RUßPARTIKELFILTER
(EN) DEVICE FOR CARRYING OUT A REGENERATION PROCESS IN A SOOT PARTICLE FILTER
(FR) DISPOSITIF PERMETTANT DE METTRE EN ŒUVRE UN PROCESSUS DE RÉGÉNÉRATION DANS UN FILTRE À PARTICULES DE SUIE
Abstract
(DE) Vorrichtung (10) zur Durchführung eines Regenerationsvorgangs in einem Rußpartikelfilter(12), wobei dem Rußpartikelfilter (12) ein Oxidationskatalysator (20) zur Erhöhung der Temperatur eines von einem Dieselmotor (14) zugeführten Abgasstroms (16) vorgeschaltet ist. Erfindungsgemäß wird einem mittels des Dieselmotors (14) betriebenen Hydraulikkreislauf (22) eine parasitäre Last (24) zugeschaltet, wenn sich ergibt, dass ein auf eine Regeneration des Rußpartikelfilters (12) hinweisendes Auslösekriterium erfüllt ist.
(EN) The invention relates to a device (10) for carrying out a regeneration process in a soot particle filter (12), an oxidizing catalyst (20) being arranged upstream of said soot particle filter (12) in order to increase the temperature of an exhaust gas flow (16) that is supplied by a diesel engine (14). According to the invention, a parasitic load (24) is connected to a hydraulic circuit (22) that is driven by means of the diesel engine (14) if a trigger criterion that indicates a regeneration of the soot particle filter (12) is satisfied.
(FR) L'invention concerne un dispositif (10) permettant de mettre en œuvre un processus de régénération dans un filtre à particules de suie (12), un catalyseur d'oxydation (20), qui est destiné à augmenter la température d'un flux de gaz d'échappement (16) amené depuis un moteur diesel (14), étant monté en amont du filtre à particules de suie (12). Selon l'invention, une charge parasitaire (24) est ajoutée à un circuit hydraulique (22) actionné au moyen du moteur diesel (14), lorsqu'il s'avère qu'un critère de déclenchement, signalant une régénération du filtre à particules de suie (12), est satisfait.
