REDUCTANT DELIVERY SYSTEM

摘要

Disclosed is a reductant delivery system comprising a reductant tank, a reductant delivery mechanism, a reductant pressure source, and an extraction passage. The extraction passage is coupled fluidly to the reductant tank and the reductant pressure source therebetween. The reductant delivery system also comprises a reductant manifold that comprises a junction positioned therein. Further, the reductant manifold comprises (1) a supply passage coupled fluidly to the reductant pressure source and the junction therebetween, (2) a dosing passage coupled fluidly to the reductant delivery mechanism and the junction therebetween, and (3) a return passage coupled fluidly to the reductant tank and the junction therebetween. The reductant delivery system comprises a reductant quality sensor positioned in the supply passage.
