An injector nozzle assembly for delivering a reducing agent fluid stream into an exhaust gas stream comprises a connector having an inlet for fluidly connecting to a reducing agent fluid source. The assembly further includes a cap that is connected to a nozzle body having a frustoconical portion. The assembly also includes an injector pipe having a length along an axis and passing through an opening in the cap into and through an at least partially hollow internal volume of the nozzle body. The injector pipe has an inlet fluidly connected to the connector and an outlet fluidly connected to a spray head. The spray head includes three to four substantially radial injection orifices. The injection orifices on the spray head are substantially aligned in a horizontal plane, and only oriented generally parallel to a flow direction of the exhaust gas stream.
