Cummins Every Time - Oil & Gas

The Cummins QSX combines an advanced dual overhead cam design with proven Cummins heavy-duty components. The result is dependable performance without compromise, every hour of every workday. Everywhere oil and gas business needs power.

Maintenance has been consolidated so your QSX has less downtime, with extended service intervals. Available in a range of ratings from 350-635 hp, the QSX not only meets Tier 2 emissions standards, its advanced design can reach Tier 3 requirements as well with minimal changes. And the Cummins Advisor makes specifying the right features and operating parameters easy every time.

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

The high-pressure injection system and electronic controls of the QSX ensure clean, powerful and efficient operation every time. Fuel is injected at pressures of up to 30,000 psi, for cleaner, more complete combustion.

Add to that our patented wastegated turbocharger and you have an engine capable of delivering optimum performance at every rpm. The wastegated turbo maximizes output without overboost at high speed and increases airflow at lower speeds for improved responsiveness.

Versatility.

No matter what type of oil and gas job you have to do - the QSX is designed to work as an integral part of your equipment. Our electronic control module has the built-in capacity and connections to take input from all your other vehicle and equipment systems and adjust engine performance to match.

And everything that makes this a great engine for original equipment also makes ita great engine for repowers.

Cummins QSX has these standard features:

Dual Overhead Cams - The first drives the high-pressure fuel system, the second operates the intake and exhaust valves, with a set of lobes dedicated to operating the Intebrake™ system.
High-Pressure Fuel System - Up to 30,000 psi for cleaner, more complete combustion.
Heavy-Duty Rings, Pistons, Bearings - Built to last in excess of 21,000 hours (35% load factor) with high-output design.
Engine Protection - Early detection system minimizes potential damage, downtime.
Fleetguard® ES Oil and Fuel Filters - Allow 500-hour service intervals.
Water-In-Fuel Sensor - Integrated into the fuel filter, alerting the operator when water-contaminated fuel is present so preventive measures can be taken before damage occurs.

Maintenance Intervals.

Oil drain intervals for the Cummins QSX are set for 625 hours or 6 months. Filters are vertically mounted for easy access and rapid changing, with no messy spills. Polyvee belts have auto-tensioners, so they never need adjusting. Metallic gaskets have an edge-molded design for 100% leak-free operation. Plus, with the QSX you won't need to adjust the overhead for 3 years or 3,000 hours.

Dipsticks and oil fills are available from both sides of the engine. And there are three drain ports available, so you never have to worry about having access to maintenance points.

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

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.

Cummins PowerMatch.

Cummins partners with OEM engineers to test and match the power of the QSX 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.

Cummins 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.
