Beschreibung
Zusammenfassung:	A mixer element of an exhaust treatment apparatus for an internal combustion engine includes a semi-tube having a closed first end and an open second end. The first end includes a fluid inlet configured for connection to an emission fluid injector of the exhaust treatment apparatus. The semi-tube is configured to induce swirl into an exhaust gas flow across the semi-tube. A plurality of bladed discs are spaced axially apart along a tube axis of the semi-tube. The plurality of bladed discs are configured and positioned to induce a helical component to the exhaust gas flow relative to the tube axis. Each bladed disc includes a plurality of blades extending from a disc hub.
