Cummins announced today that it will add Selective Catalytic Reduction (SCR) aftertreatment to its heavy-duty products for 2010 to deliver the best fuel efficiency for its customers.


Last September, Cummins announced it would not use any NOx aftertreatment for its heavy duty engines, although it would use SCR technology for midrange.

Cummins will combine recent advancements in catalyst technology with its unique engine systems. This will provide customers with significant fuel economy improvements, in addition to meeting the near-zero emissions levels required by the Environmental Protection Agency's 2010 regulations, Cummins says.

Cummins Emission Solutions, a leading provider of SCR systems, will supply integrated exhaust aftertreatment systems for Cummins heavy duty and midrange engines.

As previously announced, the ISX engine family also will incorporate the XPI fuel system, proven cooled exhaust gas recirculation, the Cummins VGT turbocharger, Cummins particulate filter and advanced electronic controls for the best performance, fuel economy and reliability.

"Cummins expertise in engine system integration means that we have the capability to make the engine systems and aftertreatment technologies work together seamlessly," said Steve Charlton, Vice President, Heavy-Duty Engineering. "The addition of the new SCR catalyst technology ensures that Cummins will deliver the best fuel economy in the industry and total operating cost benefits to our customers."

"This move demonstrates Cummins ability to adapt to a changing environment by leveraging technology advancements from our midrange engine development and Cummins Emission Solutions," said Ed Pence, vice president and general manager, Heavy-Duty Engine Business. "Our 2010 engine development is progressing on plan, and customers can depend on Cummins to deliver these new products on time, with the reliability, performance and fuel economy
that they have come to expect from us."
