COLUMBUS, Ind. (October 18, 2010) - Cummins (NYSE: CMI) announced today the shipment of nearly 37,000 EPA 2010-certified engines with Selective Catalytic Reduction (SCR) aftertreatment since their introduction in January. Engine shipment volumes and early customer experiences have further confirmed the company’s confidence in SCR to not only meet today’s near-zero Oxides of Nitrogen (NOx) standards, but to also deliver significant fuel economy improvements and to serve as a foundation for future clean-diesel developments to meet greenhouse gas and fuel-efficiency regulations.

Cummins has manufactured and shipped nearly 37,000 EPA 2010-certified engines to customers across North America through the end of September. Cummins engine plants in Jamestown, N.Y.; Rocky Mount, N.C.; and Columbus, Ind., serve over 60 customers who deliver clean-diesel-powered vehicles to America.

Customer feedback also confirms the benefits of Cummins integrated engine and aftertreatment systems, including its industry leading ISX15, with reports validating that the engines are delivering up to 6% better fuel economy as compared with their EPA 2007 counterparts.

“The positive feedback we’re receiving from customers across North America in various environments is in line with both Cummins and customers’ expectations of our 2010 products. SCR is a key factor in enabling our engines to achieve these fuel economy improvements and performance standards,” said Rich Freeland, President – Engine Business.

Cummins will join leaders from the Diesel Technology Forum (DTF) at the Clean Diesel 10 event, hosted by the EPA, to celebrate 10 years of cleaner air through the National Clean Diesel Campaign (NCDC) and the Diesel Emissions Reduction Program (DERA), in Washington, D.C., on Oct. 19 and 20. The ISX15 and Cummins Aftertreatment System will be showcased by Cummins during the event.

“Cummins is pleased to be with the Diesel Technology Forum this week to commemorate the evolution that the industry has made toward clean diesel,” said Srikanth Padmanabhan, Vice President and General Manager – Cummins Emission Solutions. “Ten years ago, the EPA’s Heavy-Duty Highway Diesel Rule was finalized, and the engines on display today are delivering over 90% reduction in Oxides of Nitrogen and Particulate Matter. Getting diesel emissions to near-zero levels over the last decade was a challenge that Cummins embraced as a technology leader in the industry. With SCR technology, I’m confident that the next decade will provide many advances that are mutually beneficial to clean air and satisfied customers.” he added.
