Cummins choose SCR future

Cummins has announced that it will add Selective Catalytic Reduction (SCR) aftertreatment to its Heavy-Duty products for the US market in 2010 to deliver the best fuel efficiency for its customers.

The SCR technology will be included in the next generation of engines for North America in order to meet US EPA 2010 at emission levels not due for introduction here in Australia until 2013.

As previously announced, Cummins’ Heavy-Duty ISX engine family will incorporate the XPI fuel system, proven cooled Exhaust Gas Recirculation, the Cummins VG 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.”

When asked whether there were technical difficulties with the previously announced non-SCR engine, Cummins strenuously denied.

“That product was all set to launch in January, 2010,” said Steve Charlton, vice-president of heavy-duty engineering with Cummins. “The program was performing well, the product was performing well and we were hitting all our targets.”
