Cummins Particulate FilterMeeting Low Emissions With The Right Technology
Cummins QSX15, QSX11.9, QSL9 and QSB6.7 engines ranging from 174-hp to 600-hp (130-447 kW) will meet the 2011 low emissions standards with an integrated Cummins Particulate Filter exhaust aftertreatment and a cooled exhaust gas recirculation (EGR) system incorporated with the engine.The cooled EGR system enables clean combustion with NOx reduced by 45% compared to Tier 3, while the Cummins Particulate Filter exhaust aftertreatment system reduces particulate matter by over 90% from engine exhaust. Particulate aftertreatment technology is new to the off-highway equipment industry – but it is not new to Cummins. Cummins introduced on-highway engines in 2007 certified to EPA standards in North America using both cooled EGR and the Cummins Particulate Filter. Our experience of using EGR extends back to 2002.Cummins designs and manufactures the Cummins Particulate Filter as an integrated system with the engine. Meeting Tier 4 Interim and Stage IIIB demands new levels of system integration in order to achieve very low emissions while improving performance. Cummins capability with this technology is unmatched in the industry, reflected in these production figures at the start of 2011: EGR engines produced: over 1 million Particulate filter aftertreatment systems produced: 650,000
