Abstract
A NOx reduction device for diesel vehicles includes an Lean NOx Trap (LNT) serving as a NOx filter, a Diesel Particulate Filter (DPF) located downstream of the LNT, and a Hydrocarbon-Selective Catalyst Reduction (HC-SCR) catalyst provided on the LNT. The HC-SCR catalyst can remove NOx in the regeneration of the DPF even if an additional post injector is not provided to promote an active reaction of the HC-SCR catalyst.
