Cummins reaffirmed Monday that its entire on-highway product range will be ready to meet the new Environmental Protection Agency regulations for the North American market beginning in 2010.
Cummins says it will offer a range of engines from the 6.7-liter ISB to 15-liter ISX.
However, published reports indicate the Environmental Protection Agency is concerned that the copper zeolite Cummins plans to use could case carcinogenic dioxins. Cummins announced last August that it had changed its mind about using selective catalytic reduction, or SCR, for 2010 engines, citing "recent advancements in catalyst technology." Other engine manufacturers are using iron zeolite in their catalytic process.
For 2010, Cummins will introduce the ISX15, which it says will provide substantial fuel economy improvement, stronger performance, faster throttle response and overall best-in-class drivability and reliability compared to today's ISX engine. The ISX15 will feature the new Cummins XPI fuel system, next generation cooled EGR system, advanced VGT 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, VGT turbocharger, Cummins Aftertreatment System and advanced electronic controls.
Cummins will also offer its ISB6.7, ISC8.3 and ISL9 engines for 2010 for medium-duty trucks and bus applications. The 2010 engines will all use Cummins VGT turbocharger, Cummins Aftertreatment System, a common ECM and advanced electronic controls. The ISC8.3 and ISL9 also feature Cummins XPI fuel system.
"Cummins 2010 engines will deliver what customers need in these challenging economic times," said Jim Kelly - President, Engine Business. "The engines are already being built 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."
