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 utilizing SCR/DEF technology, which means the new Cummins engine lineup for on-highway applications meets the near-zero emissions standards required for all engines manufactured that took effect Jan. 1, 2010. “Receiving the formal certificates is an important step in the process as we enter 2010 with customer-ready products,” said Jim Kelly, engine business president. “This confirms that customers can be confident in the technology choice we’ve made to meet the new, more stringent emissions standards. Our decision to use SCR technology has given us the ability to provide customers with the most fuel efficient engines for on-highway applications. We expect to see at least 5 percent fuel economy improvement for the ISX15 and up to 3 percent improvement for the MidRange products.” Kelly said incorporating SCR technology will also require the use of Diesel Exhaust Fluid (DEF) at an average rate of 2 percent of diesel fuel consumption. DEF is currently available at numerous retail locations throughout the U.S. and Canada, including all Cummins distributor locations.
