Las Vegas (September 27, 2004) - Cummins Inc. (NYSE:CMI) is featuring the Tier 2 QSK60 engine for the mining market with the top rating increased to 3000 hp (2238 kW) at the 2004 MINExpo International Show.

The rating has been developed specifically to meet the reliability and high power density requirements of 300-plus ton (272 metric tonnes) haul trucks. This new engine rating will be available in 2006 and will meet the Environmental Protection Agency's (EPA) Tier 2 emissions requirements.

The QSK60 will utilize a Cummins modular common-rail fuel system that is designed for mining, with full-authority electronic control over fuel timing, quantity, pressure and delivery rate shape. Precision control over the number of injection events enables optimum performance and emissions compliance.

Cummins Tier 2 QSK60 achieves a 30% reduction 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.

"We've invested in the right products, proven technology, people and infrastructure to help our customers achieve the uptime they require," said Ed Claypool, General Manager - Mining Markets. "Cummins remains focused on providing customer support and technology to the mining market that's better than any other competitor," he added.

Covering an 1800 - 3000 hp (1343 - 2238 kW) range, the 60-liter, V16 configuration features single-piece ferrous cast ductile (FCD) iron pistons that allow for high cylinder pressures and increased power output with exceptional durability while reducing maintenance costs. The QSK60 will be offered with a choice of single-stage or dual-stage turbochargers.

Cummins has been able to optimize the in-cylinder combustion system to meet Tier 2 NOx levels without increasing displacement or making significant configuration changes which means minimal OEM installation impact. 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 the addition of aftertreatment.
