摘要
In order to check the efficiency of an NOx accumulation catalyst (3) mounted in the exhaust system of an internal combustion engine (1) operated with a lean mixture, the actual accumulation capacity of the NOx accumulation catalyst (3) is determined and the NOx accumulation catalyst is diagnosed as defective when a predetermined minimum capacity is not reached.
