Cummins Highlighting Customer-Inspired Technology At Railway Interchange 2015
MINNEAPOLIS (Oct. 4, 2015) – Cummins Inc. (NYSE: CMI) presents its ultra-clean 6.7-, 15-, 60- and 95-liter diesel engines at Railway Interchange, Oct. 4-6. Delivering 140 hp (104 kW) to 4400 hp (3281 kW), the engines offer quieter operation and increased fuel economy for everything from Maintenance-of-Way to Locomotives while also meeting increasingly stringent emissions regulations worldwide.
At 4400 hp (3281 kW), the QSK95 achieves the highest output of any 16-cylinder high-speed diesel, and is capable of a top speed of 125 mph (201 km/hr) as a prime mover. Combining Cummins latest-generation Modular Common Rail Fuel System (MCRS) with quad-turbocharging, the QSK95 delivers reduced noise, excellent response and ultra-low-emissions capability.
The QSK60 (2310 and 2700 hp/1723 and 2013 kW), which received Tier 4 Locomotive certification from the United States Environmental Protection Agency (EPA) on Thursday, October 1, is an industry leader in productivity and total life-cycle value. A one-piece cast iron block, single-piece ferrous cast ductile iron pistons and a heavy-duty crankshaft and connecting rods are the foundation of the engine, delivering outstanding reliability and durability. The same MCRS that powers the QSK95 is also used on the QSK60, bringing low noise, unmatched performance and excellent fuel economy to the package.
For switcher/shunter applications, the QSX15, with a Tier 4 Locomotive rating of 600 hp (447 kW), will be on display. Xtra-High Pressure Injection (XPI) coupled with fully integrated electronic controls allows for flexibility in injection timing that increases fuel economy and performance, while Cummins proprietary VGT® Turbo provides superior response. Multiple engine designs allow the QSX15 to provide power-on-demand response to varying load factors, resulting in fuel savings and a reduced carbon footprint.
Cummins QSB6.7, Tier 4 Final certified, is one of the most popular and versatile engines in the Maintenance-of-Way market. With 140 hp (104 kW) to 300 hp (224 kW), it combines high strength with a compact footprint, for one of the best power-to-weight ratios in its class.
All Cummins engines are designed to meet increasingly stringent emissions regulations worldwide using aftertreatment technologies that are developed and manufactured in-house. This approach ensures that our systems are integrated to work in a fully optimized manner that increases efficiency while allowing Cummins to have complete quality control, with robust design and testing procedures that ensure all rail engines meet performance standards everywhere they are operated.
Deep understanding of available aftertreatment technologies allows Cummins to choose the most appropriate solution for each engine platform based on the needs of applications at each power range. Leveraging that expertise results in the ideal pairing of engine and aftertreatment, such as the fit-and-forget Selective Catalytic Reduction (SCR) and Diesel Oxidation Catalyst (DOC) used on the QSB6.7, or the SCR-only system that occupies the space utilized by exhaust silencers in high-horsepower applications like the QSK95.
