    Abstract: An exhaust treatment system may include gas, reductant and water conduits, a nozzle and a pump. The gas conduit may be in fluid communication with a source of compressed gas and may include a first valve controlling a flow of compressed gas through the gas conduit. The water conduit may be in fluid communication with a water source and may include a second valve controlling a flow of water through the water conduit. The nozzle may be in fluid communication with the gas, reductant and water conduits. The pump may be disposed between the nozzle and the second valve and may be in fluid communication with the reductant and water conduits. The pump may be operable in a first pumping direction to pump reductant from the reductant source to the nozzle and in a second pumping direction to pump reductant away from the nozzle and toward the reductant source.

    Abstract: An exhaust gas treatment system for reducing emissions from an engine includes an exhaust conduit adapted to supply an exhaust stream from the engine to an exhaust treatment device. The conduit includes an aperture. An injector injects a reagent through the aperture and into the exhaust stream. A flow modifier is positioned within the exhaust conduit upstream of the injector. The flow modifier includes a diverter for increasing the velocity of the exhaust gas at a predetermined location within the conduit relative to the injected reagent.

    Abstract: An exhaust gas treatment system for reducing emissions from an engine includes an exhaust conduit adapted to supply an exhaust stream from the engine to an exhaust treatment device. An injector injects a reagent through an aperture in the conduit into the exhaust stream. A flow modifier is positioned within the exhaust conduit and comprises a plate including a plurality of bores spaced apart from one another and positioned about a periphery of the plate. The plate also includes a plurality of slots positioned in parallel with each other.
