Abstract

The invention relates to a static mixer for an exhaust system of an internal combustion engine. The mixer has a wall structure that is arranged across the directional of flow in a pipe and has several layers of a corrugated sheeting material laying across one another in the direction of flow. The cells through which the flow can pass in the direction of flow are provided between the sheeting material of neighboring layers. The sheeting material has baffles for all or several of the cells. The baffles are arranged on the sheeting material so that they are arranged on their outgoing flow side in the case of said cells and extend in the direction of flow and across it.
