Cummins Announces Right Technology for 2010

    No NOx Aftertreatment On Heavy-Duty Engines; MidRange Engines Use Proven
SCR Technology

    NASHVILLE, TENN., September 24 /CNW/ - Cummins Inc. (NYSE:  CMI) today
announced its technology approach for on-highway engines to meet the more
stringent 2010 EPA emissions standards. The company will use an evolution of
its proven 2007 solutions to maintain power and torque with comparable fuel
economy and maintenance intervals the same as today. Cummins will offer a
complete lineup of on-highway engines to meet the near-zero 2010 emissions

    Heavy-Duty Formula For Success

    Key ingredients of the Cummins 2010 Heavy-Duty lineup include:

    --  No NOx aftertreatment: NOx reduction will be achieved by 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

    --  X platform expansion and increased displacement: Cummins will expand
the Heavy-Duty X platform in North America to three displacements with the
introduction of an 11.9L engine and a 16L engine to complement its flagship
15L product. The engines will share a common architecture including the XPI
HPCR fuel system. The expansion will enable Cummins to meet a broader array of
customer needs, and marks the first time in nearly 20 years that the company
has had a common architecture across its industry-leading Heavy-Duty products.

    "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," said Ed Pence, Vice President and
General Manager, Cummins Heavy-Duty Engine Business.

    "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 drive Cummins innovation," said Dr. Steve Charlton,
Cummins Executive Director of Heavy-Duty Engineering.

    The next-generation cooled EGR is key to reducing emissions and oxides of
nitrogen (NOx). EGR technology will not add complexity to the vehicle; and
power, torque, fuel economy and maintenance intervals will stay the same.

    Cummins will continue to use its proven Variable Geometry Turbocharger
(VG Turbo), which bolsters 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 for Heavy-Duty engines in 2010. The engine and aftertreatment work
together to further reduce particulate emissions.

    MidRange Engine Evolution

    Cummins will enhance its MidRange on-highway product performance and
reliability by adding Selective Catalytic Reduction (SCR) to its existing
product to meet the near-zero 2010 emissions standards. SCR is the right
technology for Cummins medium-duty truck, bus and specialty-vehicle customers
who want a simple and proven solution to meet their diverse power and duty
cycle needs.

    "Cummins MidRange engines are known for their exceptional value," said
Dave Crompton, Vice President and General Manager, Cummins MidRange Engine
Business. "SCR enables us to extend our power range while maintaining
excellent fuel economy, maintenance intervals and overall low cost of
ownership. This translates to even better value for MidRange customers in
2010," he added.

    "Our 2007 products are working well and customers are delighted. For
2010, we will simply add a proven NOx reduction system to ensure a highly
reliable and cost-effective solution," said Jeff Weikert, Executive Director
of MidRange Engineering.

    SCR technology uses a chemical called urea and a catalytic converter to
significantly reduce oxides of nitrogen (NOx) emissions.

    SCR technology is not new to Cummins. In 2006, Cummins launched its
MidRange engines certified to the Euro 4 standard using SCR for commercial
vehicle applications in Europe.

    "Leveraging our experience in Europe, Cummins is positioned to implement
SCR better than any other engine manufacturer in North America. Our customers
can depend on Cummins to be ready with proven technology for 2010, just like
we were in 2007," said Crompton.

    Across its entire lineup of on-highway engines, Cummins is able to meet
increasingly stringent emissions regulations with speed and efficiency, due
primarily to two competitive advantages.

    First, Cummins benefits from an integrated business structure that
enables it to tap the core competencies of Cummins Emission Solutions, Cummins
Turbo Technologies, Cummins Fuel Systems and Cummins Filtration. These
businesses work together to bring to market technologically superior, fully
integrated systems. Second, Cummins benefits from its worldwide experience and
leadership with a wide range of proven technologies. Cummins continues to
execute its carefully planned product strategy, anticipating changes and
investing in the research and development necessary to meet customer needs and
environmental goals.

    All Cummins on-highway engines will be fully certified and compliant to
the near-zero EPA 2010 emissions standards.
