Abstract: front page image
(DE) Die Erfindung betrifft ein Verfahren zum Betrieb von Komponenten zur Abgasnachbehandlung, die im Abgastrakt einer abgasaufgeladenen Brennkraftmaschine angeordnet sind, wobei stromauf wenigstens einer Abgasturbine (14) ein Abgasteilstrom (11) von einem Abgas-Hauptstrom (10) entnommen wird. Der Abgasteilstrom (11) wird stromab der wenigstens einen Abgasturbine (14) wieder in den Abgas-Hauptstrom (10) zurückgeführt, wobei stromab dieser Zuführung (7) wenigstens eine Abgasnachbehandlungskomponente (6) angeordnet ist. Erfindungsgemäß wird die als Abgasteilstrom (11) abgezweigte Abgasmenge in Abhängigkeit von wenigstens einer Solltemperatur an wenigstens einer definierten Stelle im Abgastrakt, insbesondere im Abgasteilstrom (11) und/oder an der wenigstens einen Abgasnachbehandlungskomponente (6), gesteuert oder geregelt.
(EN) The invention relates to a method for operating components for exhaust gas after-treatment, which are arranged in the exhaust gas tract of a turbocharged internal combustion engine, wherein a partial exhaust gas stream (11) is removed from the main exhaust gas stream (10) upstream of at least one exhaust gas turbine (14). The partial exhaust gas stream (11) is fed back into the main exhaust gas stream (10) downstream of the at least one exhaust gas turbine (14), wherein at least one exhaust gas after-treatment component (6) is arranged downstream of said feed (7). According to the invention, the quantity of exhaust gas branched off as a partial exhaust gas stream (11) is controlled or regulated as a function of at least one target temperature in at least one defined point in the exhaust gas tract, in particular in the partial exhaust gas stream (11) and/or on the at least one exhaust gas after-treatment component (6).
(FR) L'invention concerne un procédé pour le fonctionnement de composants destinés au post-traitement des gaz d'échappement, qui sont implantés dans le système d'échappement d'un moteur à combustion interne turbocompressé. En amont d'au moins une turbine à gaz d'échappement (14), un flux partiel de gaz d'échappement (11) est extrait d'un flux principal de gaz d'échappement (10). En aval de ladite au moins une turbine à gaz d'échappement (14), le flux partiel de gaz d'échappement (11) est réintroduit dans le flux principal de gaz d'échappement (10). Au moins un composant de post-traitement des gaz d'échappement (6) est implanté en aval de cette amenée (7). Selon l'invention, la quantité de gaz d'échappement extraite sous la forme du flux partiel de gaz d'échappement (11) est commandée ou régulée en fonction d'au moins une température de consigne en au moins un point prédéterminé du système de gaz d'échappement, en particulier dans le flux partiel de gaz d'échappement (11) et/ou au niveau dudit au moins un composant de post-traitement des gaz d'échappement (6).
