Cummins Every Time - Oil & Gas

Every QSK19 engine is a powerful example of Cummins Quantum System technology at work. Including self-diagnostics, prognostics and more. The QSK19 state-of-the-art electronic controls combined with a high-pressure injection system ensures clean, powerful and efficient operation every time. These powerful engines are designed to give every oil and gas application maximum performance with minimum maintenance.

Available in a range of ratings from 525 to 800 hp, these heavy-duty diesels meet Tier 2 emissions standards* without compromise. A low-maintenance two-stage oil filter is just one of the many features that minimize downtime. Cummins PowerMatch and Advisor are ready to provide expert assistance with your spec'ing and installation process.

Every QSK19 engine comes with a 2-year/2,000-hour base warranty, with 3-year/10,000-hour standard protection on major components.

* The next-generation QSK19 engine, available in January 2005, achieves Tier 3 engine emissions standards for the oil and gas market by incorporating new combustion technology and a common-rail fuel injection system. Tier 3 compliance for the QSK19 in additional markets will be announced in the near term.

The QSK19 high-pressure injection system and electronic controls ensure clean, powerful and efficient operation every time. The ECM continuously monitors data from strategically placed sensors within the engine, optimizing the fuel-to-air mixture for maximum combustion. Fuel is injected at pressures exceeding 25,000 psi. This results in better utilization of fuel with fewer emissions. Getting more energy out of every drop of diesel fuel also results in greater power.

Versatility.

No matter what type of oil and gas job you have to do - the QSK19 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 equipment or vehicle systems and adjust engine performance to match.

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

Cummins QSK19 engines come with these standard features, so you get more power and economy out of every one of them.

Extra-Wide Gear Train - Quieter, longer-lasting and capable of handling high loads of injector pressures with ease.
Single-Stage HolsetTurbocharger - Lower intake air temperatures provide increased air density, resulting in more power and lower emissions.
Large Fan Drive and Bearings - Increased fan size for improved cooling capacity.
Full-Authority Electronic Controls - Programmable controls optimize combustion based on engine load and atmospheric conditions. Provides advanced monitoring, diagnostic, prognostic and reporting capabilities, with engine protection features.
Two-Stage Oil Filter - Combination full-flow and bypass oil filter reduces maintenance costs as it extends service intervals.
Longer-Lasting Intake and Exhaust Valves - Valve and seat are machined out of select materials for longer life. Rotators on both intake and exhaust ensure uniform wear.
Precision-Honed Cylinder Liners - Precise liner machining with superior metal technology creates exceptional surface smoothness and durability.
Articulated Steel Pistons - 30% longer life, increased reliability and improved combustion result from the two-piece piston design.
High-Durability Camshaft - Microfinishing makes it last twice as long as previous designs. Improved contact between the crosshead and rocker lever reduces wear and improves durability.

Minimum maintenance was built into every QSK19 engine. For example: the articulated pistons last 30% longer until the first rebuild, and give an additional 30% longer life after it. Even the oil seals have been engineered so they're never exposed to contaminants - for virtually leak-free operation.

Maintenance Intervals.

Cummins QSK19 engines require an oil change every 250 hours.

Cummins QuickServe®.

Cummins QuickServe offers you factory-certified technicians, the most sophisticated diagnostic and repair tools in the industry, and the largest international parts and service network of any engine manufacturer. Our worldwide team of mobile service technicians is always ready to deliver service when and where you need it. Every minute. Every day. Every year.

QSK19 engines come with a full 2-year/2,000-hour warranty that covers all Cummins branded components, including electrics such as starters and alternators. Major components coverage continues into the third year, up to 10,000 hours of operation from the time your QSK19 engine goes in service.

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.

Cummins PowerMatch.

Cummins partners with OEM engineers to test and match the power of the QSK19 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.
