    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 aftertreatment system may include an exhaust pipe and a mixing pipe. The exhaust pipe may receive exhaust gas from an engine and may include a first portion defining a first longitudinal axis and a second portion defining a second longitudinal axis that is angled relative to the first axis. The mixing pipe may be disposed in the exhaust pipe and may include a tubular portion and a collar extending radially outward from the tubular portion. The tubular portion may include a plurality of openings and a plurality of deflectors. The plurality of openings may extend through inner and outer diametrical surfaces of the tubular portion. Each of the plurality of deflectors may be disposed adjacent a corresponding one of the plurality of openings.
