Cummins Inc. has released the QSK95 engine with over 4,000-hp (2,983 kW) output, designed as the world’s most powerful high-speed diesel. 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 product line will extend up to the 120-liter, 20-cylinder QSK120, capable of over 5,000-hp (3,728 kW) output. Designed with exceptional strength and high power density, the 16-cylinder QSK95 exceeds the power output of other large 1,800-rpm high-speed engines with 20-cylinders.mc0512-products-cummins-300.jpg

Compared 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 QSK95 is ideally suited for high-hour, high-load applications in passenger and freight locomotives, many types of marine vessels and ultra-class mine haul trucks. Operators can expect higher levels of equipment uptime and a longer life-to-overhaul with the QSK95.
