Abstract

Methods and systems are provided for adjusting a regeneration scheme in response to ageing of a first catalyst and a second catalyst. In one example, a method may include determining a first ageing of the first catalyst and a second ageing of the second catalyst and updating factors of the regeneration scheme based on the first ageing and the second ageing.
