Abstract
Methods and systems for reducing emissions of an internal combustion engine are described. In one example, a combustor is applied post shutdown to purge stored NOx from a passive NOx absorber to prepare for a subsequent engine start. The trapped NOx is subsequently reduced via a selective catalytic reduction catalyst.
