Abstract: An exhaust treatment fluid delivery system (16, 22, 116) may include a supply passageway (46, 146), a supply manifold (38, 138), injectors (42, 142), a bypass passageway (50, 150) and first and second pressure sensors (34, 134, 40, 140). The supply passageway (46, 146) receives the exhaust treatment fluid from a tank (26, 126) and provides the exhaust treatment fluid to the supply manifold (38, 138). The bypass passageway (50, 150) connects the supply passageway (46, 146) with the return passageway (48, 148) and includes a bypass valve (36, 136) controlling fluid flow therebetween. The first pressure sensor (34, 134) measures a first pressure of exhaust treatment fluid in the supply passageway (46, 146) based upon which the bypass valve (36, 136) is controlled. The second pressure sensor (40, 140) measures a second pressure of exhaust treatment fluid in the supply manifold (38, 138) based upon which the injectors (42, 142) are controlled.

Abstract: An exhaust after-treatment system including at least one exhaust treatment component (18); and a particulate matter dispersion device (40) located upstream of the exhaust treatment component (18). The particulate matter dispersion device (40) includes at least one nozzle line (61) having a plurality of nozzles (58) formed therein, and the particulate matter dispersion device (40) is operable to inject compressed gas towards the exhaust treatment component (18) to substantially minimize build-up of particulate matter at the exhaust treatment component (18).
