COLUMBUS, Ind. (August 2, 2004) - Cummins Inc. (NYSE:CMI) today announced that it remains focused on mining with its solutions for the Environmental Protection Agency's (EPA) Tier 2 standards that take effect in January of 2006.

"Cummins has the global support network and the right technology to provide the best value in power solutions for mining customers' range of diesel engine applications," said Mark Levett, Vice President High-Horsepower Engine Business.

"We will continue to manufacture all products available to our customers today, and we are focused on maintaining our leadership in providing the best support, value and flexibility of anyone in the mining market. We have invested in upgrading our entire product line - across the 751- to 3500-horsepower (hp)

Tier 2 power band - to provide our mining customers with the highest levels of reliability, durability, performance and dependability, at the lowest possible cost per ton," he added. "At the same time, we are committed to meeting or exceeding clean air standards."

Cummins engines will feature an in-cylinder solution with minimal OEM installation impact. Cummins has been able to optimize the in-cylinder combustion system to meet Tier 2 NOx levels without the need for aftertreatment or other external hardware. In addition, the Cummins Tier 2 advanced combustion solution provides a stable engine system that will carry customers through to Tier 4 in 2011.

While there are many varieties and styles of fuel systems on the market today, having full-authority electronic control over fuel timing, quantity, pressure, delivery rate shape and the number of injection events is a must for optimum performance and emissions compliance. One such advanced system is the designed-for-mining common-rail fuel system, which will be used on the latest platforms of the Cummins Tier 2 engines. This system has full control over the fuel injection event in relation to timing, quantity, pressure and number of injections. Cummins Tier 2 products achieve a 30% reduction in emissions of oxides of nitrogen (NOx) and 65% reduction in Particulate Matter (PM), while maintaining reliability and durability in extreme operating environments, and still allowing customers to use widely available diesel fuels.
