QSK60 for Mining (Tier 4 Final)


QSK60 for Mining (Tier 4 Final)

In demanding mining applications such as excavators, haul trucks and wheel loaders, dependability is everything. That’s where the superior uptime and productivity of the Tier 4 Final QSK60 make a difference. Its V16 configuration offers up to 2850 hp (2125 kW) in mining applications, with simplified air handling, reduced complexity and improved serviceability. The proven QSK60 platform delivers high reliability and outstanding durability, with no loss of power or torque. Heat rejection is similar to the Tier 2 engine, so there is no need to re-engineer the cooling package. The fully integrated aftertreatment unit replaces the muffler in your equipment, minimizing design modifications. The combination of higher productivity and lower operating costs is performance that pays.

  • Base engine – A redesigned power cylinder, optimized wastegate turbocharger and improved crankcase breather system work to keep particulate matter (PM) levels low while maintaining durability and reliability. The QSK60 achieves nearly 1.1 million gallons-to-overhaul.

  • Fuel system – The Cummins Modular Common Rail Fuel System (MCRS) uses increased injection pressure and larger injector accumulator volume, for reduced PM and improved fuel economy. The leakless injector has increased fueling precision and timing control, for reduced parasitic losses, reduced fuel heating and improved fuel economy. An improved pilot valve resists wear, for enhanced reliability and durability. The fuel pump has an improved tappet design and fuel cooling of pumping elements, which contribute to longer component life.

  • Air handling – The simplified configuration of the wastegate turbochargers and intercoolers allows access to the top end of the QSK60 without removal of the air-handling system, even on our two-stage engines. Its altitude capacity exceeds the 10,500-ft requirement for Tier 4 Final engines in North America.

  • Lubrication and filtration – NanoNet® filtration captures and retains more harmful particles than traditional media, for longer fuel pump and injector life with better reliability. Oil and fuel filter change intervals have been increased to 500 hours.

  • Selective Catalytic Reduction (SCR) – Cummins modular SCR system features an integrated decomposition chamber and a Cummins airless Diesel Exhaust Fluid (DEF) dosing system designed to last the life of the engine. The use of SCR minimizes engine backpressure, for increased fuel economy. Optimized temperature management minimizes DEF consumption.
