Cummins Receives EPA 2010 Engine Certifications

Cummins Inc. said it received certification from the Environmental Protection Agency (EPA) for its 2010 Heavy-Duty big-bore ISX15 and MidRange ISB6.7, ISC8.3 and ISL9 engines.

The certifications mean the Cummins 2010 engine lineup for on-highway applications meets the near zero emissions levels required by new EPA regulations, which took effect Jan. 1, 2010. The regulations are the most stringent in the world, with oxides of nitrogen (NOx) and particulate matter (PM) emissions levels of 0.2 grams and 0.01 grams per brake-horsepower-hour respectively.

“Receiving the formal certificates is an important step in the process as we enter 2010 with customer-ready products,” said Jim Kelly, president of Cummins’ engine business. “This confirms that customers can be confident in the technology choice we’ve made.”

Cummins is using selective catalytic reduction (SCR) technology to meet the new EPA standards. Cummins said it committed to using SCR technology because of a significant increase in efficiency and durability. “Our decision to use SCR technology has given us the ability to provide customers with the most fuel efficient engines for on-highway applications,” Kelly said. “We expect to see at least 5 percent fuel economy improvement for the ISX15 and up to 3 percent improvement for the MidRange products.”

Cummins EPA 2010 engines will include an enhanced cooled EGR system and a single VGT Turbocharger. The ISX15, ISL9, and ISC8.3 feature the Cummins XPI fuel system, and the ISB6.7 features an improved high-pressure common rail (HPCR) fuel system. The new SCR catalyst is included along with the Cummins particulate filter, first introduced in 2007, in the Cummins after treatment system.

Incorporating SCR technology requires 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 United States and Canada, including all Cummins distributor locations.

Cummins Inc., a global power leader headquartered in Columbus, Ind., designs, manufactures, distributes and services engines and related technologies, including fuel systems, controls, air handling, filtration, emission solutions and electrical power generation systems.
