Abstract: A selective catalytic reduction (SCR) system includes an exhaust pipe for receiving an exhaust gas from an engine. A selective catalytic reduction (SCR) unit is provided downstream of the exhaust pipe. A first mixing element including a meshed body defines a first surface, a second surface, and a plurality of openings extending from the first surface to the second surface. The first surface and second surface are parallel to each other and define an angle relative to a flow direction of the exhaust flow. The angle is less than 90 degrees.
