Las Vegas (September 27, 2004) - Cummins Inc. (NYSE:CMI) announced today that it will offer the widest range of mining engines of any manufacturer ready for EPA Tier 2 and other emissions requirements found around the world. Cummins range extends from the QSK19 to the QSK78 and spans a 510 - 3500 hp (380 - 2611 kW) range.

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

The EPA Tier 2 regulations will apply to engines above 750 hp (560 kW) only in North America beginning in January 2006. The rest of the world will continue with current Tier 1, localized regulations or remain unregulated.

As a global supplier, Cummins will have a full range of products to offer in all of these situations. The advantage of Cummins latest Tier 2 engines is that they build upon the success of the current Tier 1 products. This ensures Cummins will be able to continue all current platforms.

The Tier 2 products will also offer additional benefits beyond emissions such as improved engine protection, longer life-to-overhaul, as well as being quieter and smoother running. This will encourage customers outside the North America Tier 2 region to utilize the latest platforms. Depending on the local requirements, customers will be able to select engine calibrations that will either maximize fuel economy or emissions reductions.

New to the range will be enhanced versions of the well-proven 38-liter and 50-liter platforms upgraded to Quantum System capability. Designated as the QSK38 and QSK50, these engines will also incorporate the latest electronics and Cummins modular common-rail fuel system to meet Tier 2 emissions and improve performance.

Cummins engines will not require increased displacement or significant configuration changes to meet Tier 2 regulations. This offers major benefits to OEMs as it reduces to a minimum any re-engineering required. Cummins has been able to optimize the in-cylinder combustion system along with incorporating a new modular common-rail fuel system to meet Tier 2. In addition, the Cummins Tier 2 advanced combustion solution provides a stable engine system that will carry customers through to Tier 4 in 2011 with addition of aftertreatment.

Cummins Tier 2 products achieve 30% reductions in emissions of Nitrogen Oxides (NOx) and over 65% reductions in Particulate Matter (PM) from Tier 1 standards, while maintaining reliability and durability in extreme operating environments, and still allowing customers to use widely available diesel fuels.
