Title: EXHAUST GAS AFTERTREATMENT DEVICE
Abstract:
The invention relates to a device for cleaning exhaust gases of an internal combustion engine, comprising an adsorption element for nitrogen oxide, a heating device, an injection device for injecting an aqueous urea solution, a catalyst for selectively catalytically reducing (SCR) nitrogen oxide, and a particle filter. The aforementioned elements are arranged on or in a flow section, and an exhaust gas can flow through the flow section along a main flow direction, wherein the adsorption element is mounted in the flow section upstream of the other elements along the main flow direction. The invention additionally relates to a method for operating the device.
