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).
