Your business depends on people who've got what it takes - supported by equipment with the power, the durability and the ratings to get the job done. Known for excellent power density, economical operation and exceptional uptime, the QSK23 is a powerful example of Cummins Quantum System technology at work. Including self-diagnostics, prognostics and more. It uses the same rugged power cylinder design proven in our larger diesels - for the performance and durability you need and the low maintenance and operational costs today's oil and gas business demands.

Available in 760-950 hp ratings, these powerful engines come with high-tech electronic features for superior reliability and durability on every job. These heavy-duty diesels meet every current EPA and Euro standard for Tier 1 and will meet Tier 2 with minor modifications.

Every QSK23 engine comes with a 2-year/2,000-hour base warranty, with 3-year/10,000-hour standard protection on major components.

The QSK23 state-of-the-art electronic controls combined with its high-pressure injection system ensures clean, powerful and efficient operation every time. The Cummins QSK23 is the ideal match for your most aggressive and specialized applications. The high-pressure injection (HPI) fuel system injects fuel at 29,000 psi for the best fuel economy of any engine in its class, while maintaining low emissions. Plus, the QSK23 has an underplate, a floating head cover, integrated front and rear gear housing and gear train, all to keep engine noise to a pleasant minimum. That's something every oil and gas operation can appreciate. Every day.

Every mechanic knows, simpler is better. That's why Cummins QSK23 has an in-line 6-cylinder configuration, versus the competition's V12.

And every foreman knows, the less time an engine spends in service, the more productive it is on the job.

Maintenance Intervals.

Consistent profitability demands continuous operation. That's why Cummins QSK23 engines only require oil and oil filter changes every 250 hours or 6 months.

When service is needed, the oil pump, water pump and accessories are all front-mounted and easy to reach.
