COLUMBUS, Ind. -- Cummins this week reported that it has shipped 37,000 EPA 2010-certified engines with Selective Catalytic Reduction (SCR) aftertreatment since their introduction in January.

Cummins said engine shipment volumes and early customer experiences have 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.

“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 has manufactured and shipped nearly 37,000 EPA 2010-certified engines to customers across North America through the end of September. The company's engine plants in Jamestown, N.Y.; Rocky Mount, N.C.; and Columbus, Ind., serve more than 60 customers that 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 percent better fuel economy as compared with their EPA 2007 counterparts, according to Cummins.
