Beschreibung
Zusammenfassung:	A diesel dosing unit (DDU) is disclosed, having a fluid injector assembly. The fluid injector assembly includes a fluid injector and an attachment assembly attached to a downstream end of the fluid injector, the attachment assembly at least partly defining a fluid path in fluid communication with a fluid path of the fluid injector. The DDU further includes a DDU housing in which the injector assembly is disposed, the DDU housing being configured to directly attach to an exhaust pipe of a vehicle. The fluid injector assembly is dimensioned to largely match the dimensions of an existing injector of a reductant delivery unit (RDU) such that the DDU housing utilizes the housing of the existing RDU.
