QSK23 FOR CONSTRUCTION (TIER 2)
Whether you are looking at powering new equipment or repowering an excavator, loader or road paver, the Cummins QSK23 is the answer every time. It delivers the performance and durability you need and the low maintenance and operational costs today's business climate demands.
Available from 760- through 950-hp ratings, these powerful engines come with high-tech electronic standard features for superior reliability and durability on every job. And with Cummins Advisor you can tailor the installation to take into account everything from load factors to operating climate for optimum performance.
Every QSK23 engine is covered by Cummins three-step warranty, one of the most comprehensive and simplest plans in the industry.
Smart torque across the rpm range gives the QSK23 the power to pull away quickly and maintain speed on an uphill climb, no matter how heavy the load. A 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 a rear gear train, all to keep engine noise to a minimum. That's something everyone on a work site can appreciate.
