Abstract
(DE)
Die Erfindung betrifft eine Ottomotoranordnung und ein Verfahren zum Betreiben der Ottomotoranordnung, wobei die Ottomotoranordnung einen Ottomotor (1) und eine Abgasnachbehandlungsanlage (2) mit einem Hauptkatalysator (3), einem Ottomotorpartikelfilter (4) und einem NOx-Speicherkatalysator (10) umfasst, wobei der Hauptkatalysator (3) als 3-Wege-Katalysator ausgebildet ist oder wirkt, wobei dem Hauptkatalysator (3) der Ottomotorpartikelfilter (4), welcher gegebenenfalls als 4-Wege-Katalysator wirkt, nachgeordnet ist, wobei dem Ottomotorpartikelfilter (4) der NOx-Speicherkatalysator (10) nachgeordnet ist, und wobei gegebenenfalls ein Oxidationskatalysator (18) vor dem NOx-Speicherkatalysator (10) angeordnet ist.
(EN)
The invention relates to a petrol engine arrangement and to a method for operating the petrol engine arrangement, wherein the petrol engine arrangement comprises a petrol engine (1) and an exhaust gas aftertreatment system (2) having a main catalytic converter (3), a petrol engine particulate filter (4) and a lean NOx trap (10), wherein the main catalytic converter (3) is designed or acts as a 3-way catalytic converter, the petrol engine particulate filter (4), which optionally acts as a 4-way catalytic converter, is arranged downstream of the main catalytic converter (3), the lean NOx trap (10) is arranged downstream of the petrol engine particulate filter (4), and an oxidation catalytic converter (18) is optionally arranged upstream of the lean NOx trap (10).
(FR)
L’invention concerne un système de moteur à allumage commandé et un procédé permettant de faire fonctionner le système de moteur à allumage commandé, ledit système de moteur à allumage commandé comprenant un moteur à allumage commandé (1) et une installation de post-traitement des gaz d’échappement (2) comportant un catalyseur principal (3), un filtre à particules de moteur à allumage commandé (4) et un catalyseur à accumulation de NOx (10), le catalyseur principal (3) se présentant sous forme de catalyseur à trois voies ou agissant comme tel, le filtre à particules de moteur à allumage commandé (4), qui agit le cas échéant comme catalyseur à 4 voies, étant monté en aval du catalyseur principal (3), et le cas échéant un catalyseur d’oxydation (18) étant monté avant le catalyseur à accumulation de NOx (10).
