ISL9 For EPA 2010.
Cooled EGR – This next-generation system lowers combustion
temperatures for reduced emissions and optimized fuel economy.
™
More of a good thing. That’s what you get with the
Cummins ISL9 EPA 2010 engine. Very few changes have
been made to the base engine in order to meet emissions
standards. So you can expect the same high level of
performance and reliability that ISL owners currently get
from every piece of equipment, handling every workload.
The ISL9 has one of the highest power-to-weight ratios
in its class, with heavy-duty features like replaceable
wet liners. It features the XPI fuel system – the same
technology that’s used on the ISX15. This, combined with
an improved Electronic Control Module (ECM) and improved
airflow, allows the ISL9 to run stronger and with greater
responsiveness than ever before.
Adding proven Selective Catalytic Reduction (SCR)
technology to our aftertreatment system with cooled EGR
and the Cummins Particulate Filter results in an engine
that delivers near-zero emissions without compromising
performance.
XPI Fuel System – The proven technology of the XPI
common-rail fuel system delivers a precise quantity of fuel
at ultra-high pressures. This, together with more robust
electronic engine controls, enables multiple injection events
per cycle. Flexibility in injection timing maximizes fuel
economy and performance while decreasing
exhaust emissions.
Fully Integrated Electronic Controls – A single higher-capacity
ECM controls everything from air intake to exhaust aftertreatment
for peak performance and near-zero emissions.
Cummins Aftertreatment System – The proven Cummins
Particulate Filter reduces particulate matter by over 90%. In 2010
it is combined with Cummins SCR to meet emissions standards
while maintaining best-in-class performance, reliability and durability.
Cummins SCR technology has been proven in over 200,000
European vehicles and uses Diesel Exhaust Fluid (DEF) to achieve
NOx emissions at near-zero levels. DEF will be readily available;
reference Cummins Filtration flyer LT15618 for more information.

ISL
FOR TRUCK AND VOCATIONAL APPLICATIONS
FoR TRuck And VocATionAl ApplicATionS.
Every Advantage.
The low cost and high performance of Cummins ISL
make it the ideal choice for a broad range of trucks,
from LTL carriers with day cabs to dump trucks, refuse
haulers and mixers. Six Sigma practices help to ensure
reliability and durability, while design modifications for
2007 make the ISL run cleaner, with excellent power
and fuel economy. The VGT™ Turbocharger even
functions as an exhaust brake, for better stopping
power and vehicle control.
How did we make all these improvements and still
meet stringent emissions controls? With a totally
integrated system that includes our proven cooledEGR subsystem, a High Pressure Common Rail fuel
injection system, the patented VGT Turbocharger,
Cummins Particulate Filter and a crankcase ventilation
system.

Gearing And Transmission
Recommendations.
The ISL matches well with all types of mechanical and
automatic transmissions. The optimum balance of
performance and fuel economy with direct or overdrive
transmissions in regional LTL and vocational applications
is achieved when the ISL is geared to cruise in the
1600-1900 rpm range.
In vocational and P&D applications using automatic
transmissions, it is best to select the proper rear
axle ratio for the vehicle’s tire size and desired top
road speed.
Log on to www.powerspec.cummins.com for more
gearing recommendations.
The Cummins Particulate Filter is designed to last the life of
your engine. Regeneration is fully automated and controlled
by the ECM. See Owner’s Manual for complete details.
