| description | The invention relates to a method for operating an exhaust gas purification system (1) for purifying an exhaust gas of an internal combustion engine, according to which, in a diagnostic operation, in directly successive operating phases of the internal combustion engine in both lean-mixture and rich-mixture operating mode, the ammonia storage capacity of an ammonia SCR catalyst (7), the oxygen storage capacity of a NOx storage catalyst (8) and optionally the NOx storage capacity of the NOx storage catalyst (8) are detected by interpretation of the signals of a first and a second exhaust gas sensor (S1, S2).
本发明涉及种操作用于净化内燃机排气的排气净化系统(1)的方法，其中，在诊断工作中，在采用稀燃工作模式及采用富燃工作模式的内燃机的彼此紧接的工作阶段内，借由对第排气传感器(S1)和第二排气传感器(S2)的信号进行评价，确定氨?SCR?催化器(7)的氨存储能力、氮氧化物储存催化器(8)的氧存储能力以及可选的氮氧化物储存催化器(8)的氮氧化物存储能力。 |
