Overview:

Since 1926, Cummins has been a force of innovation in the mining industry. With engines like our QSK23, we’re continuing to help miners break new ground in sustainable practices and reduce the cost of production. The QSK23 combines rugged productivity, high-power density and advanced engine management technology to deliver the lowest operating cost per ton of any mining engine in its class. Put the QSK23 to work in your mining operation and discover the advantages of Cummins.

Advancements

  • Modular Common Rail System (MCRS) — System works at pressures of up to 2200 bar, resulting in more complete combustion across the entire power curve.
  • EPA/ARB Tier 4 Final and EU Stage V Non-Road Certified — Meets requirements for both, providing the same efficient engine for global distribution.
  • PrevenTech® — Innovative service solution that extends engine life and reduces downtime through alerts and assisted monitoring to take care of equipment needs.

 
Reliability and Durability

  • Compact and Balanced Inline Design — Positions the QSK23 as a preferred choice for new mining equipment or repowering Vee-style engines of similar displacement.
  • Constant Design Improvements — Improved rear crank seal, rear gear train, steel pistons and flexible fuel lines.
  • Proven Track Record — Cummins’ Tier 4 high-horsepower engines have recently exceeded 10 million operating hours. 10 million operating hours translates into over 50,000 tons of particulate matter (PM) and oxides of nitrogen (NOx) avoided, reduced fuel ($30 million of financial gains for customers), and lower operating costs (since the fuel efficiency of these engines improved by up to 5% over Tier 2 engines).

 
Robust features

  • Integrated Emission System — Protects engine performance and power density, while improving fuel economy over previous engine models, without increasing heat rejection or the engine footprint, equating to better total cost of ownership (TCO).
  • Cummins HHP SCR (4000 Series) — Provides optimized performance while delivering the cleanest emissions yet.
  • Extended Nanonet Fuel Filter and Lube Filter — Can more than double filter life and keep your engine running longer, resulting in better TCO.
