3500-HP ENGINE TO LEAD CUMMINS LINEUP AT BAUMA SHOW

Power Leadership In Large Mining Equipment Highlighted By QSK78

COLUMBUS, Ind. (Jan. 21, 2010) - The 3500-hp rated QSK78 mining engine will lead the Cummins Inc. (NYSE: CMI) lineup at the 2010 BAUMA show in Munich, Germany, from April 19 to 25. The presence of the 78-liter engine will highlight Cummins position as the leading supplier of high-powered engines to manufacturers of large mining haul trucks and excavators.

The V-18 configuration QSK78 was the first engine to bring a 3500-hp (2610 kW) power capability to ultra-class mining haul trucks operating at high altitudes. The QSK78 was also the first engine of its size to feature a full-authority electronic management system, enabling engine parameters to be customized to precisely match the duty cycle of the equipment.

"The QSK78 continues to set standards in terms of life-to-overhaul and lowest cost per ton," said John Malina, Executive Director, Cummins Mining Business. "As one of the world's most powerful high-speed diesel engines, the QSK78 is set to be a focus of attention for visitors to the BAUMA show," he added.

Cummins mining display will also feature cost-saving technologies for the mine operator, such as the ELIMINATOR(TM) self-filtration system, which replaces disposable oil filters on the engine and enables oil change intervals to be extended up to 1,000 hours.

Ranging from 19- to 78-liter displacement, Cummins QSK family is uniquely designed for mining equipment. While competitive engine types are designed primarily for less demanding power generation, rail or marine applications, Cummins QSK engines are first and foremost conceived to meet the toughest demands of the mining industry.

With this inherent design advantage, QSK engines can handle high-hour and high engine load factors on a fuel-efficient basis and achieve uptime levels over 95 percent.

This is one of the reasons Cummins remains the engine supplier of choice to mining equipment manufacturers and operators worldwide, outselling the closest competitor many times over.
