COMPANY PROFILE-PAID ADVERTISEMENT Cummins—Global Power Leader About Cummins Founded more than 90 years ago, Cummins is a global power leader with complementary business units that design, manufacture, distribute and service engines and related technologies—including fuel systems, controls, air handling, filtration, emission solutions and electrical power generation systems. Headquartered in Columbus, Indiana, Cummins serves customers in approximately 190 countries and territories through a network of more than 600 company-owned and independent distributor locations and approximately 6,500 dealer locations. Cummins earned $1.85 billion on sales of $18 billion in 2011. Business Units Cummins is organized into four complementary business units: • Engine Business: Designs, manufactures and markets diesel and natural gas- powered engines for on- and off-highway equipment, as well as Genuine Cummins new and ReCon® parts – all backed by an extensive distribution network. • Power Generation: A global provider of entire systems, components and services for prime, standby, distributed and auxiliary power generation needs, including gensets, alternators, transfer switches and maintenance contracts. • Components: Specialized businesses include Cummins Filtration, Turbo Technologies, Emission Solutions and Fuel Systems, which deliver proven technology and exceptional reliability. • Distribution: Drives global distribution and channel management, with 17 company- owned distributors and 10 joint ventures across 190 countries and territories. Provides maintenance contracts, engineering services and customized integrated products. Cummins Vision Making people's lives better by unleashing the Power of Cummins. Mining Product News for 2011 In the second quarter of 2011, Cummins announced its Tier 4 Final solution for off-highway 2015 emissions standards for the broad 760- to 3,000-hp (567-2,237 kW) range of products. A combination of cleaner in-cylinder combustion and next-generation Selective Catalytic Reduction (SCR) provides a drop-in solution to meet the latest emissions hurdle. At Tier 4 Final, Cummins engines will deliver a nearly 40% reduction in oxides of nitrogen (NOx) emissions and an 80% reduction in Particulate Matter (PM) over Tier 2. This is achieved by a clean- combustion formula utilizing higher-pressure 12 E&MJ; • JUNE 2012 fuel injection and enhancements to the power cylinder design. By focusing NOx reduction within the exhaust rather than during in-cylinder combustion, Cummins avoids the need to make any major change to the external engine platform. Using SCR also leaves a much higher performance threshold in-cylinder in order to focus on PM reduction and improve fuel efficiency. Cummins experience with SCR technology dates back to 2006, with applications in Europe, and now the company benefits from having over 125,000 EPA 2010 on-highway engines in operation with SCR technology in North America. The success Cummins has achieved in clean- engine technology is through its innovative use of industry-leading technology and its insistence that everything the company does leads to a cleaner, healthier and safer environment. Also in the fourth quarter, Cummins announced the new QSK95 engine, which will provide a 4000-hp (2983 kW) capability for ultra-class mine haul trucks, representing the highest-ever power output introduced by the company for severe duty-cycle operation. The 95-liter displacement QSK95 is purpose-designed to provide enhanced strength for 360-ton and 400-ton (327 and 363 metric ton) payload-class trucks, with the capability to increase truck speeds for climbing steep-gradient haul roads and boost hauling productivity with reduced operating cycle times. The QSK95 will be available as a global mining engine platform capable of operating at mine sites anywhere in the world and meeting all emissions standards, including Tier 4 Final in North America by using Cummins proven Selective Catalytic Reduction (SCR) aftertreatment. The 16-cylinder QSK95 reaches the mining power output previously available only from 20-cylinder engines. High power density is achieved with a hardened power cylinder featuring the strongest single-piece forged steel piston available in the industry. Deep structural strength is provided by an all-new ductile iron skirted block. This increased strength contributes to higher engine uptime availability, extended life-to- overhaul and more cost-effective rebuilds.
