High efficiency conversion of nitrogen oxides in an exhaust aftertreatment device at low temperature |
摘要 |
A system and method for providing reductant to a lean NOx catalyst, when the temperature in the lean NOx catalyst is greater than 300° C., is disclosed. After the reductant is supplied under these conditions, the NOx conversion efficiency of the lean NOx catalyst in the 140-250° C. temperature range is increased.
