Abstract
Methods and systems are provided for partially regenerating a lean NOtrap in response to an engine shutdown request. In one example, an engine shutdown is delayed so that a low-temperature storing region of the lean NOtrap is regenerated without regenerating a high-temperature storing region of the lean NOtrap. A battery charge is replenished during the shutdown, wherein the charge may be consumed during a subsequent engine operation.
