Cummins Every Time - Oil & Gas

Cummins QSC makes every oil and gas application a more efficient one. Quiet, powerful operation (up to 50% less noise) significantly improves communications and operator comfort. While the heavy-duty design of the engine block and components adds reliability and durability you can count on every day, year after year. QSC combines the proven strength of the C Series engine with state-of-the-art electronic controls for high productivity that delivers the performance you need in the demanding oil and gas environment.

Ratings range from 240-340 hp, with a High-Pressure Common-Rail (HPCR) fuel system for strong performance at every rpm. A low-maintenance filter assembly is just one of many features that minimize downtime for maintenance. There are over 200 options that let you customize your QSC.

Getting the right combination to match your equipment, operating environment and workloads has never been easier. Cummins PowerMatch and Advisor are ready to provide expert assistance with your installation and spec'ing process.

Every QSC engine comes with a 2-year/2,000-hour base warranty.

Cummins QSC engines are built on one of the most successful engine block designs in the world. Add to that a free-breathing 24-valve cylinder head, a High-Pressure Common-Rail (HPCR) fuel system and robust electronic controls, and you've got a highly customizable, highly durable, highly fuel-efficient power plant that has one of the highest power-to-weight ratios and lowest costs of operation of any engine in its class.

The QSC is significantly improved over previous C Series engines, with advanced electronics, higher torque, better throttle response, shorter service times, longer maintenance intervals, increased fuel economy and up to 50% less noise. Standard features include:

Full-Authority Electronic Controls - Optimize engine operation and deliver critical information for controlling costs, reducing maintenance and seamless integration with other components.
Stiffer Block Design - For reduced noise and vibration. Fluid circuits are integrated, replacing hoses and eliminating potential leak points.
Wastegated HX40 Turbocharger - Delivers maximum power and torque at low rpm, with no overboost at high rpm.
Low-Maintenance Fuel Filter Assembly - Fuel filter incorporates an integral water separator and water-in-fuel sensor. 500-hour filter life with easy top-load replacement using standard Fleetguard® filters.
Low-Tension Belt Arrangement - This simplified design provides maximum power output through the accessory drive.
Ni-Resist Piston Inserts - Give exceptional oil control.
Mid-Stop Cylinder Liners - Reduce cavitation and improve rebuildability.

There are many options available, so every QSC can be customized to a specific piece of equipment or job. These include noise reduction packages with up to 3 dBA additional noise reduction, and more:

Options include:

Extended Service - Cummins, Fleetguard and Valvoline have teamed up to develop extended service filters and lubricants that let you go beyond the 500-hour standard oil change interval, with reduced downtime and cleaner operation.
Noise Reduction Packages - Available with up to 3 dBA additional noise reduction.
Over 200 Options Available - So every QSC can be customized to a specific piece of equipment or job. These include:
- 12- or 24-volt electrical capacity
- Flywheels
- Flywheel housings

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.

QSC 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 QSC 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.

PowerMatch.

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