Cummins Reaffirms Readiness For EPA 2010 Regulations

Cummins Inc. reaffirmed that its entire on-highway product range, including its ISX, will be ready to meet the new Environmental Protection Agency (EPA) regulations for the North American market beginning in 2010.

Cummins will offer a range of engines from the 6.7-liter ISB to 15-liter ISX, delivering fuel economy and performance while complying with
the EPA's newest and most stringent emissions standards.

For 2010, Cummins will introduce the ISX15, which will provide substantial fuel economy improvement, stronger performance, faster throttle response and overall best-in-class drivability and reliability compared to today's industry leading ISX engine. The ISX15 will feature the new Cummins XPI fuel system, next-generation cooled EGR system, turbocharger and a new Cummins Aftertreatment System that incorporates Selective Catalytic Reduction (SCR) catalyst technology.

Cummins will also introduce the new ISX11.9, providing a compact and lightweight medium-bore engine ideal for vocational trucks, emergency vehicles and motorcoach applications. Building on Cummins Engine and Components Business expertise, the ISX11.9 will have common subsystems with the ISX15, including the XPI fuel system, turbocharger, Cummins Aftertreatment System and advanced electronic controls.

Cummins market share of the heavy duty on- highway business has grown from 27 percent in 2006 to over 45 percent in 2008.

Cummins will also offer its ISB6.7, ISC8.3 and ISL9 engines for 2010.

"Cummins 2010 engines will deliver what customers need in these challenging economic times,” said Jim Kelly - President, Engine Business. "The engines are already being produced off our production lines for customer field tests. We're getting great feedback from our field tests, and our products, our people and our customer support are ready for 2010. In addition to the fuel economy gains associated with SCR and our XPI fuel system, the performance and reliability enhancements that come with decreased EGR rates are even greater than we estimated, and we're convinced now more than ever that SCR technology is the right technology for 2010."
