Cummins Inc. has 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. Certification of these engines means that the Cummins 2010 engine lineup for on-highway applications meets the near zero emissions levels required for all engines manufactured in 2010.
The new EPA regulations, which took effect Jan. 1, 2010, are the most stringent emissions regulations 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,” says Jim Kelly, President, Engine Business. “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 EPA 2010 near-zero emissions standards. Cummins committed to using SCR technology because of a step change in performance, which provides 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. 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 says.
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 fuel system. The new SCR catalyst is included along with the Cummins Particulate Filter, first introduced in 2007, in the Cummins Aftertreatment System. 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 United States and Canada including all Cummins Distributor locations.
With the introduction of the new EPA 2010 engines, Cummins maintains engine availability across a broad range of on-highway applications. The MidRange ISB6.7, ISC8.3, and the ISL9 are designed for and available in a wide variety of applications, including recreational vehicles.
