Beschreibung
Zusammenfassung:	A mixer assembly for mixing an injected reductant with an exhaust gas output from a combustion engine includes an outer housing, a tubular inner housing, and an injector. The outer housing includes an outer wall defining an exhaust gas passageway that can receive exhaust gas. The inner housing is disposed within the outer housing and includes a longitudinal axis, a first end, a peripheral wall, and an outlet. The peripheral wall is at least partially formed by wire mesh. The outlet is disposed at a second end of the inner housing opposite the first end of the inner housing. The injector is fixed to the inner or outer housing to dose the reductant into the interior of the inner housing. The wire mesh includes openings to receive at least a portion of the exhaust gas. The outlet of the inner housing discharges a mixture of exhaust gas and reductant.
