Abstract
(DE)
Die Erfindung bezieht sich auf ein kompakt bauendes Abgasnachbehandlungssystem (48) für eine Verbrennungskraftmaschine (24) mit zumindest einem Bauteil (34, 54) mit katalytischer SCR-Funktion, das zwischen zumindest zwei Mischeinheiten (32, 38), denen jeweils eine Dosierstelle (30, 36) für einen Betriebs-/Hilfsstoff zugeordnet ist, aufgenommen ist. Das zumindest eine Bauteil (34, 54) mit katalytischer SCR-Funktion und die zweite Mischeinheit (38) bilden eine bauliche Einheit (42).
(EN)
The invention relates to an exhaust-gas aftertreatment system (48) of compact construction for an internal combustion engine (24), having at least one component (34, 54) which has a catalytic SCR function and which is accommodated between at least two mixing units (32, 38), each of which is assigned a metering point (30, 36) for an operating/auxiliary substance. The at least one component (34, 54) with catalytic SCR function and the second mixing unit (38) form a structural unit (42).
(FR)
L’invention concerne un système compact de post-traitement des gaz d’échappement (48) pour un moteur à combustion (24) comportant au moins un composant (34, 54) doté d’une fonction de réduction catalytique sélective (SCR), lequel au moins un composant est reçu entre au moins deux unités de mélange (32, 38) à chacune desquelles est associé un point de dosage (30, 36) pour un combustible/adjuvant. L’au moins un composant (34, 54) doté d’une fonction SCR et la seconde unité de mélange (38) forment une unité structurelle (42).
