XPI 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.
Single Overhead Cam - Improved XPI fuel system eliminates the need for a second camshaft. This provides weight savings and simplifies operation.
VGT™ Turbocharger - Enhanced response and control with electric actuation for infinite adjustment, providing exact boost at any rpm. Sliding-nozzle design increases reliability and durability.
Cooled EGR - 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 emission standards while maintaining best-in-class performance, reliability and durability.
