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
line-up for on-highway applications meets the near zero emissions levels
required for all engines manufactured in 2010, according to a news
The new EPA regulations, which took effect Jan. 1, 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,” said Jim Kelly,
president of Cummins’ 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 said.
Cummins EPA 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. 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 Heavy-duty ISX15 offers fuel economy leadership for
the heavy-duty Class 8 truck market along with better performance and
better reliability compared to today’s industry-leading ISX. And, the
MidRange ISB6.7, ISC8.3, and the ISL9 are designed for and available in a
wide variety of applications, including medium-duty truck, school bus,
fire and emergency and recreational vehicle markets.
To best serve customers in the vocational and less-than-truckload
markets, the Cummins ISX11.9 will be introduced later in 2010. The
ISX11.9 is on target for limited production in mid-2010 with full
production commencing in late summer of 2010. Cummins will submit
necessary documentation for EPA 2010 certification for the ISX11.9 later
this year, prior to introduction to the marketplace.
