Abstract

The invention relates to an exhaust gas aftertreatment device for an internal combustion engine, where the device comprises: an exhaust duct allowing a through-flow of exhaust gas; a catalytic NOx converter arranged in the exhaust duct; and a fluid inlet arranged to introduce a liquid reductant into or onto a structure in the exhaust duct upstream the catalytic NOx converter. The invention is characterized in that the structure is a sorption structure having pores configured to retain the liquid reductant in liquid form until it evaporates. The invention also relates to a vehicle provided with such a device.
