Cummins Every Time - Mining

The QSK45 engine was developed for mining and designed based upon the strength, performance and durability of the Cummins QSK60-Non-Certified. With thousands of engines installed by nearly every major mining equipment manufacturer, you can be sure to find a QSK45 operating reliably in every corner of the world. This is because these engines have a lower operating cost per ton with better reliability than other mining engines of their size. Whether you're powering a large excavator, loader or haul truck, you can expect exceptional fuel economy for years to come with an absolute minimum of downtime. In fact, QSK45 engines routinely achieve over 95% uptime in mining operations with load factors exceeding 40%. Plus, even Cummins engines with non-certified emissions ratings generate clean power at former EPA Tier 1 levels.

The Prelub™ system, a standard feature, eliminates wear from hot and cold starts. Plus, options like Cummins ELIMINATOR™ and CENTINEL™ keep you running for extended intervals between filter and oil changes.

With ratings from 1200-2000 hp (895-1491 kW), you'll have all the power you need for large excavators, loaders and haul trucks.

Every QSK45 engine is covered by Cummins base warranty, one of the most comprehensive and simplest plans in the industry.

QSK45 customers also benefit from reduced maintenance and exceptional customer support.

Forged High-Strength Tensile Steel Crankshaft - Along with dual viscous dampers, reduces gear train wear and counterweights provide vibration damping for long engine and equipment life.
Heavy-Duty Front Gear Train - Low gear loading and high fatigue strength for dependable service.
Cummins Integrated Electronic Control System - Allows users to tailor fuel system calibrations to most unique application requirements.
Quantum System Electronics - High-speed Electronic Control Module (ECM) with a self-cooling mount is isolated from detrimental vibration loading. A field-proven, fully-sealed wiring harness with fail-safe connectors integrates the ECM with the engine sensors for optimized engine performance, monitoring and protection. Quantum system technology is ideal for tough mining applications that demand continuous uptime carrying hundreds of tons capacity.
High-Pressure Injection (HPI) Fuel System - Provides a high-peak injection pressure for optimum combustion for low emissions and better fuel economy. HPI fuel injection provides a “soft” injection start for lower combustion noise. Other benefits include excellent cold-starting characteristics and improved transient response at all engine speeds.
Power Cylinder Package - One-piece Ferrous Cast Ductile (FCD) iron pistons provide the strength and durability to handle high cylinder pressures for long life. Seven-bolt cylinder head supports increased power output with improved breathing and higher fuel efficiency.
Dual Piston-Cooling Nozzles - Direct cooling streams of oil beneath each piston for long life with increased reliability.
Wiring - Embedded in a solid foam material and completely sealed in an aluminum housing for reliability in harsh environments.
Prelub™ System - Distributes oil to rifles and friction surfaces and builds oil pressure before cranking can occur. A pressure switch assures proper oil pressure in the main rifle to reduce the risk of starting the engine without oil in the sump or filters. Prelub is a standard option on all mining engines due to proven success in extending engine life-to-rebuild.
Two-Stage Cummins Oil Filters - Also available as Fleetguard® combine full-flow and bypass filtration to effectively remove harmful sludge and up to three times as many contaminants to reduce engine wear.
Premium Fan Drive – Incorporates large matched and sealed bearings, improved oil seals, and an improved idler system. The fan drives have fixed fan centers with tensioning provided by a manually adjusted and maintenance free idler. The fan drive is available with or without an electronically controlled oil-actuated fan clutch.

Longer Service Intervals - Achieved with Centriguard™ centrifuge filters, the CENTINEL™ continuous oil replacement system and the self-cleaning ELIMINATOR™ full-flow/bypass filtration system

Centriguard™ Centrifuge Filters - The Fleetguard Centriguard from Cummins Filtration is available for aftermarket installation to complement the spin-on lube filters for greater engine protection.

CENTINEL™ Continuous Oil Replacement System – Extends oil drain and oil filter life, while improving the protective quality of engine oil. Minimizes oil disposal costs, reduces downtime and increases productivity.

ELIMINATOR™ Filtration System – Eliminates oil filter disposal headaches with a full-flow and centrifugal system that incorporates a permanent core. This optional feature eliminates up to 90% of lube system maintenance costs while increasing uptime by allowing 1,000 hours between filter changes.

Many options are available* to ensure your Cummins engine integrates perfectly into your product, including:

Installation configuration – numerous options are available including SAE flywheels and flywheel housings, exhaust outlet configurations, and accessory drive mounts.

Alternators – 24 volt alternators are available in a size to suit your application.

Air Compressors – water cooled and available in single or twin cylinder.

Fan Hubs – multiple combinations of mounting height, drive ratio and spacers ensure compatibility with your cooling package.

Hydraulic Pump Drive – conveniently located within the engine envelope to minimize installation impact.

Cold Starting Aids – grid heater, ether injection and oil pan heaters to help your engine start even in the most extreme temperatures.

*Not all options are available for each engine family. Please contact your local Cummins distributor or dealer for more information.
