摘要
A device for reducing NOx emission in the engine exhaust stream of a Diesel engine system, the engine system comprising an exhaust line having at least a Diesel Oxidation Catalyst, DOC, a Diesel Particulate Filter, DPF, and a Selective Catalyst Reduction, SCR, system, whereby inside the DPF a NOx absorber is provided, which is suitable to store NOx at low temperatures and subsequently release NOx when a target temperature is reached. Preferably the target temperature of the NOx absorber is correlated to the activation temperature of the SCR system, the NOx absorber is distributed in the inlet channels of the DPF and comprises a washcoat element. The SCR system may be an under floor SCR.
