Title (EN) EXHAUST GAS SYSTEM WITH EVAPORATION ELEMENT
(FR) SYSTÈME D'ÉCHAPPEMENT COMPRENANT UN ÉLÉMENT D'ÉVAPORATION
(DE) ABGASSYSTEM MIT VERDAMPFUNGSELEMENT
Abstract:
(EN) The invention relates to an exhaust gas system (9) for treating the exhaust gas of an internal combustion engine, comprising a flow path which is delimited by walls, a plurality of catalysts which are arranged in the flow path, an injection point (1) for an aqueous urea solution, and an evaporation element (3) for evaporating the injected aqueous urea solution. The evaporation element (3) is made of a honeycomb body which has an inlet side and an outlet side (8), wherein the exhaust gas can flow through the honeycomb body from the inlet side to the outlet side (8) along multiple flow channels (4), and the honeycomb body is positioned at an angle (α) to the main flow direction (12) of the flow path.
(FR) L'invention concerne un système d'échappement (9) servant à traiter des gaz d'échappement d'un moteur à combustion interne, comprenant une ligne d'écoulement délimitée par des parois, une multitude de catalyseurs disposés sur la ligne d'écoulement, un emplacement d'injection (1) pour une solution d'urée aqueuse, et un élément d'évaporation (3) servant à évaporer la solution d'urée aqueuse injectée. L'élément d'évaporation (3) est formé par un corps en nids d'abeille qui comporte un côté de flux entrant et comporte un côté de flux sortant (8). Le corps en nids d'abeille peut être traversé depuis le côté de flux entrant vers le côté de flux sortant (8) le long de plusieurs canaux d'écoulement (4). Le corps en nids d'abeille est placé selon un angle (α) par rapport à la direction d'écoulement de passage (12) de la ligne d'écoulement.
(DE) Die Erfindung betrifft ein Abgassystem (9) zur Behandlung von Abgaseneines Verbrennungsmotors, mit einer durch Wandungen begrenzten Strömungsstrecke, mit einer Mehrzahl von in der Strömungsstrecke angeordneten Katalysatoren, mit einer Einspritzstelle (1) für eine wässrige Harnstofflösung und mit einem Verdampfungselement(3) zur Verdampfung der eingespritzten wässrigen Harnstofflösung, wobei das Verdampfungselement(3) durch einen Wabenkörper gebildet ist, der eine Einströmseite aufweist und eine Ausströmseite (8) aufweist, wobei der Wabenkörper von der Einströmseite hin zur Ausströmseite (8) entlang mehrerer Strömungskanäle (4) durchströmbar ist, wobei der Wabenkörper in einem Winkel (α) zur Hauptdurchströmungsrichtung (12) der Strömungsstrecke angestellt ist.
