Abstract: An aftertreatment system for a diesel vehicle includes a lean NOx trap (LNT) catalyst, which is installed at a downstream of a diesel engine, absorbs nitrogen oxide (NOx) in a lean atmosphere, desorbs nitrogen oxide (NOx) in a rich atmosphere based on a lambda window, and converts some of the desorbed nitrogen oxide (NOx) to ammonia (NH3). A selective catalytic reduction (SCR) catalyst is installed at a downstream of the LNT catalyst and purifies nitrogen oxide (NOx) that has passed through the LNT catalyst using ammonia (NH3) generated at the LNT catalyst.
