摘要： A system for an engine is shown that includes an upstream emission control device and a downstream emission control device. The upstream device has a washcoat having a predetermined amount of precious metal disassociated with NOx storage material. In one example, the upstream emission control device located in a close-coupled location receiving untreated exhaust gasses from the engine. A controller is utilized for adjusting parameters of the engine. For example, the controller operates the engine lean, with periodic rich operation to purge stored NOx during at least a portion of low engine airflow and low exhaust temperature conditions. The controller also operates the engine near stoichiometry during at least a portion of other conditions.
