Cummins Gets EPA Certification for 2010 Engines

Originally Published in MotorHome Magazine

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
