Superior driveability is now available in the industry’s
most compact 10- to 13-liter engine. Cummins ISX11.9
EPA 2010 is a clean-sheet design that delivers everything
you want – strong pulling power, excellent throttle
response and high fuel economy numbers with legendary
Cummins reliability and durability.

A high power-to-weight ratio and strong clutch
engagement torque make it ideal for severe-duty
applications like refuse haulers, dump trucks and mixers.
The horsepower range and exceptional fuel efficiency are
an ideal match for local and LTL trucking operations.

Every major component and system is designed and built
by Cummins for total quality control, and the ISX11.9
shares technology with the proven ISX15 engine.

The ISX11.9 doesn’t just replace the ISM. It surpasses it,
in every way.

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
increases fuel economy and performance while
decreasing exhaust emissions.

Cooled EGR – This next-generation system lowers combustion
temperatures for reduced emissions and optimized fuel economy.

Fully Integrated Electronic Controls – A single higher-capacity
Electronic Control Module (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 Selective Catalytic Reduction (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.

A Perfect Fit. Every™ Time.

ISM

For Oil and Gas Applications

Every Advantage.

For reliability, low operating costs and strong
performance, Cummins ISM can’t be beat.

It has one of the highest power-to-weight ratios in its
class. An advanced fuel injection system and the
patented Variable Geometry Turbocharger (VG Turbo)
result in superior performance over every terrain, in
any
condition. Cummins ISM for EPA 2007 has
comparable fuel economy to the previous model, so
you get added savings every mile.

Plus, every element has been designed and
manufactured by Cummins using Six Sigma
processes to ensure a consistently superior level of
quality in every ISM engine, every time.
