The QSX11.9 is a clean-sheet design that incorporates Cummins proven technology enablers to meet EPA Tier 4 Interim and EU Stage IIIB low emissions standard in 2011. The QSX11.9 will achieve up to 5 percent better fuel efficiency*, lowering your cost of
operation and improving your bottom line. Ratings range from 300-500 hp (224-372 kW).

cummins qsx11.9 overview

The QSX11.9 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 11.9-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.
