Cummins reveals new QSK95 Engine at Seymour Engine Plant in Indiana
On November 1, 2011, Cummins Inc. revealed the new QSK95 engine that features over 4,000-hp (2983 kW) output, which makes the engine the world’s most powerful high-speed diesel. Unveiled at the Seymour Engine Plant in Seymour, Indiana, 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 5000-hp (3728 kW) output. The 16-cylinder QSK95 exceeds the power output of other large 1800-rpm high-speed engines with 20-cylinders.
The QSK95 will power the new C3000 Series genset from Cummins Power Generation, providing 3.5-MW high-speed output. For multiple-set applications, the high-output of the C3000 Series will increase power installation efficiency and realize higher economies of scale.
The C3000 Series genset is suited to provide critical power protection for facilities requiring high-output gensets such as data centers, hospitals and utilities. In developing countries, the C3000 Series meets the need for high-output gensets to support gaps in the power grid infrastructure.
The C3000 Series genset has the ability to meet stringent EPA Tier 4 Final emissions taking effect in 2015. Cummins Selective Catalytic Reduction (SCR) aftertreatment system is intended to replace the exhaust muffler on the genset.
“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,” said Mark Levett (pictured below), Cummins Vice-President and General Manager – High-Horsepower Business.
The QSK95 is pre-engineered to add four cylinders and will achieve over 5,000-hp (3728 kW) with the QSK120 engine. The QSK120 will utilize the same architecture and systems as the QSK95, providing the advantage of platform commonality.
Cummins has committed major resources to the new QSK95 and the high-horsepower platform, with 150 engineers working on the project and over $100 million invested to establish a new production line and world-class test facilities at the Seymour Engine Plant.
