The heavy-duty QSX engine from Cummins increases displacement to 16 L and incorporates an XPI high-pressure common-rail fuel system to improve power output and engine response. Available with a fully integrated air intake to exhaust aftertreatment system to meet EPA Tier 4 Interim and European Stage IIIB off-highway emissions regulations by January 2011, the QSX features a particulate filter exhaust aftertreatment that reduces particulate matter (PM) emissions by 90% and cooled exhaust gas recirculation that reduces NOx by 45%. A crankcase filter reduces blowby gas emissions, and the engine offers a top rating of 650 hp (485 kW) extended down to 400 hp (298 kW) to cover a range of heavy-duty applications. Peak torque is 2150 lb·ft (2915 N·m).
