Title (DE) VERFAHREN ZUR REGENERATION EINES RUßPARTIKELFILTERS
(EN) METHOD FOR THE REGENERATION OF A SOOT PARTICLE FILTER
(FR) PROCÉDÉ DE RÉGÉNÉRATION D'UN FILTRE À PARTICULES
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Regeneration eines Rußpartikelfilters (9), der auslassseitig an einem Verbrennungsmotor (1) angeordnet ist, mit: Erfassen eines Beladungswertes des Rußpartikelfilters (9); Erfassen einer Betriebstemperatur des Rußpartikelfilters (9); Abschalten eines Zylinders (2) des Verbrennungsmotors (1); Starten einer Frischluftzufuhr in den Rußpartikelfilter (9) über den abgeschalteten Zylinder (2a); Einstellen eines Zylinderventils (3; 4) zum Steuern der Frischluftzufuhr; Regenerieren des Rußpartikelfilters (9). Die Erfindung betrifft weiter eine Steuerung, einen Verbrennungsmotor (1) sowie ein Kraftfahrzeug (100) zur Durchführung eines solchen Verfahrens.
(EN) The invention relates to a method for the regeneration of a soot particle filter (9), which is arranged on the outlet side of an internal combustion engine (1), said method comprising the following steps: detecting a loading value of the soot particle filter (9); detecting an operating temperature of the soot particle filter (9); switching off a cylinder (2) of the internal combustion engine (1); starting a supply of fresh air to the soot particle filter (9) via the switched-off cylinder (2a); setting a cylinder valve (3; 4) to control the supply of fresh air; regenerating the soot particle filter (9). The invention further relates to a controller, an internal combustion engine (1) and a motor vehicle (100) for carrying out a method of this kind.
(FR) L'invention concerne un procédé de régénération d'un filtre à particules (9) placé côté échappement d’un moteur à combustion interne (1), qui comprend les étapes suivantes : saisie d'une valeur de charge du filtre à particules (9) ; saisie d'une température de fonctionnement du filtre à particules (9) ; mise hors circuit d'un cylindre (2) du moteur à combustion interne (1) ; démarrage d'une alimentation en air frais dans le filtre à particules (9) par l'intermédiaire du cylindre mis hors circuit (2a) ; réglage d'une soupape de cylindre (3 ; 4) pour commander l'alimentation en air frais ; régénération du filtre à particules (9). L'invention concerne en outre une commande, un moteur à combustion interne (1) ainsi qu'un véhicule à moteur (100) pour la mise en oeuvre d'un tel procédé.
