Cummins Every Time - Fire & Emergency

Responding Faster. Every Call. ISX11.9 for EPA 2010.

Superior response is now available in the industry’s most compact 10-13 liter engine.

Cummins ISX11.9 EPA 2010 is a clean-sheet design that takes the place of our legendary ISM engine – with superior throttle response, an exceptional power-to-weight ratio, and heavy-duty components for reliability and durability.

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.

At Cummins, we know that every second is critical when you’re responding to an emergency. There’s no room for doubt about the readiness of your equipment – or its ability to get you to the scene in a hurry.

Being able to meet budgets is critical as well – and that’s where the ISX11.9, with its long service intervals and excellent fuel economy, can come to the aid of your operating budget.

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

More information about the performance, standard features, and maintenance intervals for this engine is available online or from your Cummins representative.

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.

VGT™ Turbocharger – The Cummins VGT Turbocharger is both simple and precise. Electric actuation allows infinite adjustment, providing the exact amount of boost necessary for superior response. The proven slidingnozzle design has best-in-class reliability and durability.

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 nearzero
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.
