More Miles. Every Gallon. ISX15 for EPA 2010.

Cummins ISX15 EPA 2010 delivers superior driving performance while improving industry-leading fuel economy. Plus, it achieves near-zero emissions levels without sacrificing the reliability or durability that you expect from a Cummins engine.

Every major component and system is designed and built by Cummins for total quality control, building on a proven engine with fully integrated electronics. An improved, more precise air-handling system has reduced restriction, which helps optimize performance.

The result is that Class 8 truck owners will achieve up to 5% more miles per gallon with the ISX15. In addition, maintenance intervals are unchanged from previous years. So the ISX15 will deliver the lowest operating costs of any engine in its class.

For superior fuel economy, strong performance, long-range durability and exceptional dependability, you’ve got every reason to spec an ISX15.

Features & Benefits

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.

Intebrake™ – Even with one overhead cam, the ISX15 still has best-in-class braking horsepower (up to 600 bhp) for greater vehicle control with reduced service brake wear.

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.

Single Overhead Cam – Our improved XPI fuel system eliminates the need for a second camshaft. This provides weight savings and simplifies operation.

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 sliding-nozzle design has best-in-class reliability and durability.
