Abstract

The present invention relates a system for the treatment of an exhaust gas of a diesel combustion engine, said system comprising a specific NOx adsorber component, a diesel oxidation catalyst (DOC) component, a selective catalytic reduction (SCR) component, a gas heating component, and a reductant injector, wherein in said system, the specific NOx adsorber component is arranged upstream of the gas heating component, the reductant injector is arranged up-stream of the SCR component, the gas heating component is arranged upstream of the reductant injector, the DOC component is arranged upstream of the reductant injector, and the DOC component and the gas heating component are directly consecutive components. Further, the present invention relates a process for preparing such a system and use thereof.
