Cummins adds SCR to 2010 engines

Cummins will add selective catalytic reduction (SCR) aftertreatment to its diesel engines for 2010.

The company will combine recent advancements in catalyst technology with its unique engine systems to 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, said officials.

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, Cummins' heavy-duty ISX engine family will incorporate the XPI fuel system, cooled exhaust gas recirculation (EGR), 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,” noted Cummins vice president of heavy-duty engineering Steve Charlton.
