Cummins Announces Tier 4 Projects, Field Testing Program
Cummins Inc. announced it is undertaking more than 400 machine integration projects using the latest generation of Cummins QSF2.8 to QSX15 Tier 4 engines and after treatment to meet near-zero emissions regulations. The projects range from 49 hp to 675 hp (37-503 kW), and with approximately 70 OEMs producing machines used in construction, material-handling, mining and other industrial applications.
Cummins moved to full production of Tier 4 final/stage IV 6-cylinder engines and exhaust after treatment systems in January 2014. At CONEXPO, Cummins is displaying more than 25 new models in products including an excavator, drill rig, road planer, bulldozer, paver and telehandler, and various types of cranes. The equipment features Cummins Tier 4 Final engines that meet the Jan. 1, 2014, emissions regulations for machines rated above 174 hp (130 kW). The projects underway include the latest Cummins 4-cylinder QSF3.8 and QSB4.5 engines. There were pre-production versions supplied to OEMs ahead of the Tier 4 Final effect date of Jan. 1, 2015, for engines within the 75 hp-to-173 hp (56-129 kW) power category
Cummins also announced its Tier 4 final/stage IV field-test program has exceeded 140,000 hours with operators working on nearly 70 different machines, encompassing a wide range of applications and duty cycles. The equipment is operating on sites selected specifically to cover the most challenging conditions and extremes of temperatures. Equipment includes a snow groomer in the Alps, a container handler working the port side and a rock drill working on a mine site.
Cummins uses the monitoring to optimize engine calibrations and operating characteristics to achieve the highest fuel economy and better torque delivery. Initially focused on the QSB6.7, QSL9 and QSX15 6-cylinder engine range across the 174 hp-to-675 hp (130-503 kW) power range, the field-test program then expanded to incorporate the heavy-duty QSG12 and compact QSF2.8. Field-testing is also underway with the 4-cylinder QSF3.8 and QSB4.5 engines, ready for the Jan. 1, 2015, Tier 4 Final emissions effect date for the 75 hp-to-173 hp (56-129 kW) power category.
