Cummins has revealed the new QSK95 engine with over 4,000hp (2,983kW) output. The 95-liter 16-cylinder QSK95 is the first engine to be introduced in a new high-horsepower diesel and gas platform from Cummins. The new product line will extend up to the 120-liter 20-cylinder QSK120, capable of over 5,000hp (3,728 kW output).
Cummins claims that compared with much larger medium-speed engines operating below 1,200 rpm, the QSK95 offers a far more compact and cost- effective solution to achieve the same power output.
The QSK95 is suited for high-hour, high-load applications in ultra-class mine haul trucks. It is EPA Tier 4 Final compliant, using a Selective Catalytic Reduction (SCR) after-treatment designed by Cummins to replace the exhaust muffler.
Mark Levett, Cummins vice-president and general manager for the High-Horsepower Business commented: "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.
"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. During the development of the QSK95, we engaged with hundreds of potential users to ensure that we fully reflected their operational and installation needs."
