NASHVILLE, Tenn. (September 23, 2007) - Cummins Inc. (NYSE:CMI) announced today that its 2010 Heavy-Duty engines will not require NOx aftertreatment. Instead, the engines will incorporate an integrated technology solution comprised of the XPI High Pressure Common Rail (HPCR) fuel system, next-generation cooled Exhaust Gas Recirculation (EGR), advanced electronic controls, proven air handling and the Cummins Particulate Filter.


Cummins also announced that it will introduce an 11.9L engine and a 16L engine to complement its flagship 15L product, thereby significantly bolstering its Heavy-Duty engine portfolio for the North American market in 2010.


"We're excited to reveal that our Heavy-Duty X platform will expand to include three displacements, all featuring a common architecture that includes the XPI High Pressure Common Rail fuel system," said Ed Pence, Vice President and General Manager, Cummins Heavy-Duty Engine Business. "This is the first time in nearly twenty years that we've had common architecture across our Heavy-Duty products," he continued.


"Having the ability to meet a broader range of customer needs with an expanded product line using Cummins proven technology is our formula for success in 2010 and beyond. We will continue to deliver products in 2010 with unrivaled performance, reliability, durability and the lowest cost of operation available in the marketplace," added Pence.


Cummins leads the U.S. on-highway truck market with cooled-EGR technology, which reduces emissions and oxides of nitrogen (NOx). The next-generation EGR does not add complexity to the vehicle; and power, torque, fuel economy and maintenance intervals will remain the same as today.


The 2010 solution for Cummins Heavy-Duty engines is the result of sophisticated engineering refinements to the combustion, air handling and cooled-EGR technology integration. Cummins is the only engine manufacturer with the in-house capability to design, produce and integrate key engine subsystems to deliver a total product solution.


"Designing and producing the best-in-class Heavy-Duty diesel requires expertise in combustion, air handling, fuel systems, electronic controls and exhaust aftertreatment. That expertise and the ability to balance customer and environmental needs drives Cummins innovation," said Dr. Steve Charlton, Cummins Executive Director of Heavy-Duty Engineering.


The 2010 engines will incorporate the XPI High Pressure Common Rail (HPCR) fuel system designed and built by the company's Cummins-Scania joint venture. The HPCR fuel system generates better performance and cleaner exhaust by maintaining high injection pressures regardless of engine speed for exceptional performance across the entire rpm range.


The company will continue to use the proven and reliable Variable Geometry Turbocharger (VG Turbo) designed by Cummins Turbo Technologies. The unit incorporates a sliding-nozzle design that is electrically actuated and electronically controlled for optimized boost at given exhaust gas recirculation rates and operating conditions. The VG Turbo plays multiple roles in providing total engine performance from power output to response to superior engine braking, while working in tandem with the cooled EGR subsystem.


The Cummins Particulate Filter, designed and manufactured by Cummins Emission Solutions and introduced in 2007, will be the only aftertreatment required in 2010.


Cummins Heavy-Duty engines will be fully certified and compliant to the near-zero EPA 2010 emissions standards.
