Launching the engine at its Seymour, Indiana, plant, Cummins announced that Toronto commuter operator GO Transit will be the first QSK95 customer in North America, with an order for the repowering of 11 MotivePower MP40 locomotives.http://www.cummins.com/cmi/displayMoreN ... A00%3A00.0
SEYMOUR, Ind. – Cummins Inc. (NYSE: CMI) today revealed at the Seymour Engine Plant the new QSK95 engine with over 4000-hp (2983 kW) output 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 new product line will extend up to the 120-liter 20-cylinder QSK120, capable of over 5000-hp (3728 kW) output.http://cumminsengines.com/every/news/20111101BR02.page?
Designed with exceptional strength and high power density, the 16-cylinder QSK95 exceeds the power output of other large 1800-rpm high-speed engines with 20-cylinders. 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.
For commuter and intercity locomotives, the QSK95 is capable up to 4200-hp (3132 kW) and can be installed with an auxiliary Cummins rail engine to provide electrical hotel power to the passenger cars, freeing up maximum tractive power from the prime mover. The QSK95 engine is also available rated from 3500-hp to 4000-hp (2610-2983 kW) as a highly cost-effective power solution for multipurpose short-haul freight locomotives.
For large line-haul freight locomotives requiring more than 4000-hp output, the QSK95 can be specified with a smaller Cummins locomotive engine as a combined power installation. A smart power-sharing system transfers work between the two Cummins engines to match the locomotive duty cycle more efficiently than a conventional single engine. This innovative approach provides full traction power when the locomotive needs it and the best possible fuel economy when running at lower power levels, to reduce overall operating costs.
The exceptional strength of the QSK95 will improve locomotive traction and increase acceleration, boosting performance with highly responsive quad-turbocharging.
