Cummins Every Time - Oil & Gas

Every day, the QSM with Quantum System electronic controls provides high productivity power for equipment on the world's most demanding oil and gas worksites. And every day, they deliver. With superior performance that's the result of advanced combustion technology and our responsive wastegated turbo. Electronically controlled unit injectors, with cam-driven rate shaping, optimize the emissions and efficiency.

Maintenance is kept to an absolute minimum, with oil change intervals that are double the previous standards in some applications, sealed sensors and an auto-tensioning belt drive.

Available in a range of ratings from 245-400 hp, the QSM meets EPA Tier 2 and Euro Stage II as well as EPA Tier 3 and Euro Stage IIIA emissions standards without compromise.

The QSM comes with virtually every feature standard.

To ensure that every QSM is perfectly matched to every piece of equipment, Cummins engineers work with the original equipment manufacturers to shape power curves and ratings to align with work environment, load factors and operating modes. Then, we optimize the engine's performance with other vehicle components and subsystems, using Cummins PowerMatch and Advisor.

Every QSM engine comes with a 2-year/2,000-hour base warranty, with 3-year/10,000-hour standard protection on major components.

The QSM high-pressure injection system and electronic controls ensure clean, powerful and efficient operation every time. The ECM (Electronic Control Module) continuously monitors data from strategically placed sensors within the engine, optimizing the fuel-to-air mixture for maximum combustion. This increases engine responsiveness, improves fuel efficiency and significantly reduces noise levels.

The QSM Quantum System provides superior fuel economy with strong engine performance, engine protection and other programmable features. Components include:

Holset HX55 Turbo - Designed for optimum boost across operating range. Ratings above 350 hp are wastegated.
CELECT™ Electronic Engine Management - Provides superior performance, fuel efficiency, diagnostics and prognostics using full-authority electronics. Its programmable features let you customize engine performance to equipment use.
Sealed Sensors - Fully sealed to resist water intrusion. Combined temperature and pressure sensors reduce inventory and simplify maintenance.
Advanced Combustion Technology - Optimized injector tips and a reshaped steel piston bowl improve fuel economy and emissions control with longer change intervals.
Articulated Pistons and Liners - Steel-topped pistons handle higher cylinder temperatures for improved fuel efficiency and emissions control.
Improved Camshaft Durability - Exhaust valve lobes are designed to improve wear tolerance. The injector lobe profile has been revised to optimize injection.

The QSM was designed to deliver more time on the job and less time being serviced. Maintenance intervals have been made longer and service has been made simpler.

Maintenance is kept to an absolute minimum, with oil change intervals that are double the previous standards in some applications.

Cummins QSM engines feature a Venturi™ oil filter by our Fleetguard subsidiary in combination with an improved lube system that increases oil flow, reduces lubrication delay at start-up and improves protection. This system allows for oil change intervals of up to 700 hours in some applications.

For complete maintenance information, please consult your Owner's Manual or Operations and Maintenance Manual.

Cummins QSM gives you everything you need, with one of the simplest and most comprehensive plans anywhere. It includes full 2-year/2,000-hour complete coverage, with 3-year/10,000-hour standard protection on major components.

Three simple steps explain everything you need to know:

Step One: Full coverage on all Cummins industrial engines and branded components with unlimited hours during the first year of operation. This includes Cummins branded electrics such as alternators, starters, etc.

Step Two: Full coverage is extended for the second year, up to 2,000 hours of operation. Total hours are cumulative from the time the engine goes in service.

Step Three: Major components coverage including block, crankshaft, camshaft and rods on all products for the third year or up to 10,000 hours of operation. Total hours are cumulative from the time the engine goes in service.

For complete warranty details, please see the US and Canadian warranty brochure (3381321) or International warranty brochure (3381322).

Getting every installation right - the first time - is as important to Cummins as it is to you. PowerMatch and Advisor help ensure that we get it right, every time.

PowerMatch.

Cummins partners with OEM engineers to test and match the power of the QSM engine to specific equipment models and applications. We use our advanced electronics to shape power curves and ratings to match the jobs your equipment will be doing, taking into account the working environment, load factors, ambient temperatures and operating modes. Then we optimize the engine's performance with other vehicle components, using Advisor.

Advisor.

Advisor software builds a virtual model to make sure every system (air, intake, exhaust, cooling) is integrated for optimum performance. It takes into account everything from load factors to operating climates to duty cycles - then identifies systems or components that could negatively impact reliability - listing alternatives that will deliver the performance you expect the first time - every time.
