Cummins receives EPA certification for 2010 engines

Posted on January 8, 2010

COLUMBUS, Ind. — Cummins Inc. has received EPA certification for its 2010 heavy-duty big-bore ISX15 and MidRange ISB6.7, ISC8.3 and ISL9 engines.

The certification signifies that the Cummins 2010 engine lineup for on-highway applications meets the near zero-emissions levels required for all engines manufactured this year.

The ISB6.7 (pictured) and ISC8.3 models are used for school bus applications.

"Receiving the formal certificates is an important step in the process as we enter 2010 with customer-ready products," said Jim Kelly, president of engine business for Cummins. "This confirms that customers can be confident in the technology choice we've made to meet the new, more stringent emissions standards."

Cummins will utilize selective catalytic reduction (SCR) technology to meet the 2010 EPA standards. Cummins said it committed to using SCR technology because of a change in performance that provides a significant increase in efficiency and durability. Kelly said that the company expects to see an at least 5-percent fuel economy improvement for the ISX15 and up to 3-percent improvement for the MidRange products.

Cummins 2010 engines will include an enhanced cooled EGR system and a single VGT (TM) Turbocharger. The ISX15, ISL9 and ISC8.3 feature the Cummins XPI fuel system, and the ISB6.7 features an improved High Pressure Common Rail fuel system. A Cummins particulate filter is included along with the new SCR catalyst. Incorporating SCR technology will also require the use of Diesel Exhaust Fluid.
