San Diego, CA (October 6, 2008) - Cummins Inc. (NYSE:CMI) debuted today its complete product portfolio for transit and shuttle bus markets at the American Public Transportation Association (APTA) Expo. Cummins displayed diesel, diesel-electric hybrid and natural gas technologies all designed to meet the near-zero 2010 emissions standards. The breadth of product offerings demonstrates Cummins commitment to the transit and shuttle bus markets. “Today Cummins offers a suite of technologies, including diesel, natural gas and hybrids that meet customers’ needs in the transit and shuttle bus markets,” said Tom Hodek, Cummins General Manager – Worldwide Bus Business. “We’re delighted to continue to offer this wide portfolio of options to meet the 2010 emissions standards. Cummins is committed to providing products with the right technology and an extensive and capable service network to stand behind them.”

For 2010 Cummins will offer its MidRange diesel engines with the same proven base architecture as today along with the Cummins Aftertreatment System to meet the near-zero 2010 emissions standards. Cummins ISB and ISL engines will continue to deliver exceptional product performance and reliability with enhancements to the totally integrated system, which includes proven cooled EGR, High Pressure Common Rail fuel system, Variable Geometry Turbocharger, filtration, and electronic controls. The Cummins Aftertreatment System will include Selective Catalytic Reduction (SCR) technology for reduction of Oxides of Nitrogen (NOx) in addition to the Cummins Particulate Filter, which was introduced in 2007.

SCR technology uses a chemical called Diesel Exhaust Fluid (DEF) and a catalytic converter to significantly reduce NOx. Cummins has successfully been using SCR for a number of years in Europe and will leverage that experience for its EPA ’10 on-highway products.

The ISL G engine from Cummins Westport – which already meets 2010 emissions – will remain a strong element of the product portfolio for the transit and shuttle bus markets. Additionally Cummins will continue to offer diesel-electric hybrid engines for 2010, also with the addition of SCR.

“Cummins will have a complete lineup of engines fully certified and compliant to the 2010 EPA standard,” said Hodek. “Customers can be confident in Cummins support today and in the future.”
