 Cummins Inc. has released its new QSX11.9 and QSX15 heavy-duty engine duo to the off-highway industry. Featuring the performance-enhancing technology of Cummins Xtra-High Pressure Injection (XPI) fuel system and a variable geometry turbocharger, the company says they represent a leap forward in high-power productivity for construction, agricultural and mining equipment across the 300- to 600-HP range. The 11.9-liter and 15-liter QSX are supplied as fully integrated air-intake-to-exhaust aftertreatment systems to meet 2011 EPA Tier 4 Interim and EU Stage IIIB regulations. The engines use a particulate filter to reduce particulate matter emissions by more than 90 percent.
