The QSK50 combines the durability of the legendary Cummins K50 with the strength of single-piece ferrous cast ductile iron pistons that provide a 10% longer life-to-overhaul compared to two-piece pistons. Its V16 configuration offers ratings up to 2100 horsepower (1567 kW). Standard features include full-authority electronic controls that provide complete engine monitoring, automatic adjustment for peak performance and fuel efficiency, plus full diagnostics and prognostics.

The QSK50 also achieves a 30% reduction in NOx plus a 65% reduction in particulate matter to meet Tier 2 emissions standards* with in-cylinder technology.

Programmable parameters let you customize engine performance for lower costs. And Quantum System electronic engine management technology includes Advanced Engine Monitoring, an optional feature that lets you monitor equipment performance on the job in real time, cylinder by cylinder.

The base warranty includes full coverage on the QSK50 engine and Cummins branded components for unlimited hours during the first year of operation, extending through 2 years or 2,000 hours (whichever comes first). The base warranty also includes 3-year/10,000-hour standard protection on major components.

QSK50 customers also benefit from reduced maintenance and exceptional customer support.
