“That’s why we purpose-designed the QSK95 to set standards of uptime availability and in-service reliability higher than those of any other engine. During the development of the QSK95, we engaged with hundreds of potential users to ensure that we fully reflected their operational and installation needs. “The QSK95 moves Cummins into a significantly higher power class, and we know that many of our customers have been eagerly anticipating us making that move. “Our new QSK95 represents a landmark in the evolution of the large high-speed diesel engine, designed with the power and durability to surpass all other high-speed engines while also challenging much larger and higher capital cost medium-speed engines,” says Mark Levett, Cummins Vice President and General Manager – High-Horsepower Business. It will also power the new C3000-series genset from Cummins Power Generation, providing a class-leading 3.5 MW high-speed output, while for offshore oil and gas platforms, the QSK95 will be available as a ready-to-install drilling power module.įor all applications, the QSK95 is ready to meet the world’s most stringent emissions standards, including US EPA Tier 4 to take effect in 2015, using proven Selective Catalytic Reduction (SCR) aftertreatment designed by Cummins to replace the exhaust muffler. The QSK95 is ideally suited for high-hour, high-load applications such as ultra-class mine haul trucks, many types of marine vessels, and passenger and freight locomotives. The new product line will eventually extend up to the 120-litre 20-cylinder QSK120, capable of over 5000 hp.ĭesigned to provide exceptional strength and high power density, the 16-cylinder QSK95 exceeds the power output of other large 1800 rpm high-speed engines which have 20 cylinders.Ĭompared with much larger medium-speed engines operating below 1200 rpm, the QSK95 offers a far more compact and cost-effective solution to achieve the same power output. The 95-litre 16-cylinder QSK95 is the first engine to be introduced in a new high-horsepower diesel and gas platform from Cummins. With an output of 4000 hp and more, Cummins’ new QSK95 is the world’s most powerful high-speed diesel engine. The new 4000 hp QSK95 is the highest horsepower diesel engine ever developed by Cummins. QSK95 is the start of a new high-horsepower diesel and gas platform covering 12, 16 and 20 cylinders.
