In demanding oil and gas applications, dependability is everything. That’s where the superior uptime and productivity of the QSK38 makes the difference. Dependability makes the new QSK38 the right engine choice. Every time. Its V-12 configuration offers up to 1260 horsepower (940 kilowatts), an excellent choice for high load factors. With full-authority electronic controls that provide complete engine monitoring, automatic adjustment for peak performance and fuel efficiency, plus full diagnostics and prognostics.

Whether running mudpumps and draworks on mechanical installations or driving SCR sets for electric rigs, the Cummins QSK50 engines provide optimum performance, reliability, and versatility for drilling. This rugged 4-cycle Cummins industrial diesel delivers reliable power, low emissions, and fast response to load changes.

SERIOUS POWER FOR SERIOUS OPERATIONS WE’RE ALWAYS EVOLVING THE QSK50, AND IT SHOWS The QSK50 builds upon its legendary robustness with enhanced engine power and improved reliability while in compliance with EPA Tier 4 and EU Stage V emissions regulation.

The new Tier 4 Locomotive engine with Modular Common Rail Fuel System (MCRS) is one of the Quantum Series from Cummins with innovative technology that delivers more for less.   It gives:

1268-16414 kW | 1700-2200 hp

Outwork. Outrun. Outperform. In demanding oil and gas applications, dependability is everything. That’s where the superior uptime and productivity of the Tier 4 Final QSK50 make the difference. Its V16 configuration offers up to 2500 hp (1864 kW) – an excellent choice for tough fracing jobs.

More With Less. The inline 4-cylinder B4.5 delivers 16 percent more power and 11 percent more torque than the current version of this engine. The Cummins-designed wastegate turbo is a key component in delivering exceptional power and responsiveness for faster cycle times Not only do you get more power - you use less fuel, with total fluid efficiency (included both fuel and Diesel Exhaust Fluid) improved by up to 3 percent. Equipment used in duty cycles with frequently idling can improve fuel economy even more with Cummins Stop-Start technology.

Parented from the legendary KTA50, the QSK50 EPA Tier 2 drilling power modules are designed, developed, assembled and tested inhouse by Cummins. Every component from the engine to the alternator is built to provide optimum performance, reliability, and versatility for oil and gas drilling applications requiring EPA Tier 2, China Stage 3 or non-emissionized standards. The complete power module package is backed by Cummins service network and warranty, ensuring greater uptime availability and increased rig efficiency.
