QSX15 Specifications

XPI Fuel System – The proven technology of the XPI common-rail fuel system delivers a precise quantity of fuel at ultra-high pressures. This, together with more robust electronic engine controls, enables multiple injection events per cycle. Flexibility in injection timing increases fuel economy and performance while decreasing exhaust emissions.

VGT Turbocharger – The Cummins VGT Turbocharger is both simple and precise. Electric actuation allows infinite adjustment, providing the exact amount of boost necessary for superior response, so the QSX15 needs only a single turbocharger, whereas many competitive engines need two.

Cooled EGR – This next-generation system has been rebalanced for use with SCR, reducing flow volume and minimizing Diesel Exhaust Fluid (DEF) consumption levels.

Fleetguard NanoNet Fuel Filters – Fleetguard fuel filters with NanoNet advanced media provide up to 13 times greater protection against particles 4 microns and larger.

Fully Integrated Electronic Controls – A single higher-capacity Electronic Control Module (ECM) controls everything from air intake to exhaust aftertreatment, for peak performance and near-zero emissions.

Cummins Diesel Particulate Filter And Selective Catalytic Reduction – Cummins Diesel Particulate Filter (DPF), proven highly effective at Tier 4 Interim, virtually operates as a passive device, with active regeneration required less than 1 percent of operating time and no impact on equipment operation.
