The Cummins ISX delivers the best fuel economy of any heavy-duty diesel engine in its class. It also continues to lead the industry in reliability and durability. Advanced features and benefits include:

• Cummins Particulate Filter – Fully integrated to deliver uncompromising performance and reliability. Cummins design allows regeneration even in adverse operating conditions and reduces particulate matter more than 90%.
• Dual Overhead Camshafts – One camshaft drives high- on all Cummins products. pressure fuel injection for clean responsive power. The second camshaft operates the intake and exhaust valves, with dedicated lobes for the integrated engine brake.
• Cummins Intebrake™ – Provides greater vehicle control and reduced service brake wear. Up to 600 braking horsepower.
• Fully Integrated Electronic Controls – A single ECM (Electronic Control Module) controls the engine and aftertreatment. Also coordinates interaction with the transmission, ABS, engine brake, cooling fan and more. High-Pressure Fuel Injection System – For cleaner, more complete combustion.
•  Variable Geometry Turbocharger – Enhanced response and control with electric actuation for infinite adjustment, providing exact boost at any rpm. A sliding-nozzle design sets the industry standard for reliability and durability.
• Cooled Exhaust Gas Recirculation – Lowers combustion temperatures for reduced emissions and optimized mpg.
• Crankcase Ventilation System – Electronically managed for optimum efficiency without adding parasitic load or complexity to the engine. The coalescing filter is easily serviced, only needing replacement once a year or every 125,000 miles (200,000 km).
• SmartTorque Ratings – Deliver up to 200 lb-ft of extra torque in the top two gears for better fuel economy, fewer shifts and less driver fatigue.
• Optional Water-in-Fuel Sensor – Alerts the driver to contamination that could cause performance and durability problems.
• Service Network – Cummins engines are backed by the strength of Cummins global network of over 5,500 service locations worldwide.
