Abstract
The aftertreatment system using a Lean NOx Trap catalyst and a DPF was adapted to a light-duty diesel engine for commercial vehicle. We carried out transient mode emission tests with this system. As a result, we comprehended characteristics of the Lean NOx Trap catalyst and problems on transient mode operation. The investigation of these phenomena under transient condition and the improvement of the system are described in this paper.
