Whether you are manufacturing a large excavator, wheel loader, grader, rock drill or compressor, the QSX15 is engineered to deliver the economical, reliable power and performance that you expect from a Cummins engine. In fact, the QSX15 for Tier 4 Final offers ratings that are capable of achieving over a 50 percent increase in torque while at the same time getting better fuel economy.
The QSX15 for 2011 incorporates Cummins proven technology enablers to meet EPA Tier 4 Interim and EU Stage IIIB low emissions standard. With ratings from 400 – 600 hp (298 - 447 kW), the QSX15 will achieve up to 5 percent better fuel efficiency*, lowering your cost of operation and improving your bottom line.
The QSX15 achieves these very low emission levels by using our proven cooled Exhaust Gas Recirculation (EGR) and Cummins Particulate Filter. Both systems have been specifically developed for industrial applications delivering premium performance and durability you can depend on.
The Tier 4 Interim and Stage IIIB 15-liter engine incorporates Cummins Xtra-High Pressure Injection (XPI) fuel system enabling very high fuel injection pressure across all engine rpm speeds, providing cleaner combustion and improved engine response. Together, the fuel system and Cummins Variable Geometry Turbo (VGT™) provide optimal performance with a precise match of engine rpm and load demands.
Additional performance-enhancing features include Cummins Direct Flow air filtration system providing a 35 percent smaller installation profile than radial air filters, plus improved filtration efficiency and a crankcase ventilation system with a highly-efficient coalescing filter. Cummins Electronic Control Module manages all components for a completely integrated system providing the impressive reliability and durability and long maintenance intervals you expect from the world’s Tier 4 technology leader.
