Abstract: A nozzle including an exterior surface extending between a first end and a second end of the nozzle. The exterior surface including spray outlets disposed at the second end. An interior cavity is disposed interior to the exterior surface. A first channel and a second channel fluidly connect to the interior cavity. One or more third channels fluidly connect between the interior cavity and an individual spray outlet of the spray outlets. The one or more third channels rotate about a longitudinal axis of the nozzle and angle in a direction away from the longitudinal axis of the nozzle.

Abstract: A reductant supply system includes a pump having a suction side and a discharge side, and a tank that holds a reductant therein. A reductant supply passageway extends from the tank to the suction side of the pump so as to supply the reductant from the tank to the pump. Further, a reductant discharge passageway extends from the discharge side of the pump and is configured to supply the reductant to a reductant injection assembly that injects the reductant into an exhaust stream of an engine. The system further includes purge componentry that connects the reductant supply passageway to an ambient air source during a purging operation such that the reductant supply system draws air from the air source sequentially through the purge passageway, the reductant supply passageway, and the pump assembly to purge at least the reductant supply passageway and the pump assembly during the purging operation.

Abstract: A mixer is disclosed for use in a fluid injection system. The mixer may have an impingement floor oriented generally perpendicular to an intended fluid injection direction and generally parallel with a flow direction. The mixer may also have a first side wall connected along a lengthwise edge of the impingement floor and generally parallel with the flow direction, and a second side wall connected along an opposing lengthwise edge of the impingement floor and generally parallel with the flow direction. The mixer may further have at least one shelf extending between the first and second side walls and generally parallel with the flow direction. The at least one shelf may have a plurality of vanes protruding toward and away from the impingement floor that promotes mixing of an injected fluid.
