EVERY MILE. TM ISM FOR LINE-HAUL AND VOCATIONAL TRUCKS
FOR LINE-HAUL AND VOCATIONAL TRUCKS. With every load, Cummins ISM distances itself from every other heavy-duty diesel in its class. An exceptional power-to-weight ratio, long maintenance intervals and the lowest total cost of operation help ISM owners deliver bigger profits with every run. Features And Benefits. Thoroughly tested and proven durable, the ISM meets the latest emissions requirements without expensive aftertreatment. Other benefits of the ISM include: Industry-leading reliability and improved throttle response with the Holset Variable Geometry Turbocharger (VG Turbo). Better fuel economy, fewer shifts and less driver fatigue with SmartTorque ratings that deliver up to 100 lb-ft of extra torque in the top two gears. Exceptional power-to-weight ratio, high uptime and longest maintenance intervals. Higher resale value. Since most ISM line-haul ratings use the same hardware, uprates can be achieved with an engine software change. Proven reliability and the lowest total cost of operation.

Key Electronic Features. Load-Based Speed Control (LBSC) Improves both fuel economy and driver satisfaction by balancing performance while reducing noise. Gear-Down Protection (GDP) Improves fuel economy by encouraging the driver to operate in the top two gears. Idle Control Electronic features control idle speed, idle time, engine shutdown and PTO utilization. Road Speed Governor and Cruise Control Settings optimize both fuel economy and performance. Designed For Dependability. Every Day Of Every Year. Self-tensioning belt drive system drives both fan and alternator for reduced maintenance and increased belt life. Mid-stop cylinder liner minimizes oil consumption and increases durability. Articulated piston design featuring forged-steel crown and aluminum skirt allows for higher top ring position, optimizing fuel efficiency. Electronic Tools. INSITE For years Cummins INSITE software has been making it easy for technicians to troubleshoot, repair and service our electronic engines through easy-to-follow steps on your computer. Providing the kind of uptime you demand from your trucks. QuickCheck III Technicians can quickly and easily view engine data from any electronic diesel engine you run, using Cummins QuickCheck III and your own PDA device. For more information on hardware compatibility, please visit us at http://quickcheck.cummins.com or see Bulletin 4081450. Options That Save Money. Every Mile. Cummins C Brake by Jacobs turns your energyproducing engine into an energy-absorbing air compressor, slowing your vehicle down considerably. Service brakes last longer and tire life is extended. CENTINEL Advanced Engine Oil Management System extends oil change intervals up to 525,000 miles (840,000 km) and oil filter changes to 75,000 miles (120,000 km). Decreases maintenance cost while maximizing uptime and productivity. CENTINEL is also available in a burn-only version for vocational vehicles or anyone running local routes with routine daily maintenance. You simply add oil directly to the engine as needed, eliminating the weight and installation costs of a replenishment tank. Refrigerant compressor mounting options are available to support Sanden SD7H15 or Seltec TM21 units and come standard with automatic belt tensioners. WABCO air compressors come standard on Cummins engines, with models available in both 18.7 and 30.4 (twin) cfm. Water-in-fuel sensor alerts driver to contamination that could cause performance and durability problems. ICON Idle control unit turns engine on/off automatically, decreasing idle times and fuel consumption while maintaining engine oil temperature and battery voltage. An in-cab thermostat is available for ICON, controlling engine operation as needed to maintain driver comfort. REPTO Rear Engine Power Take-Off is available for vehicles that need an engine to do double-duty.
Line-Haul Gearing Recommendations. A major factor in optimizing performance and fuel economy is vehicle gearing. Follow these simple recommendations to ensure gearing is properly selected: For maximum fuel economy or for vehicles intending to cruise greater than 65 mph, gear for an engine speed of 1500 rpm at the 65-mph checkpoint. In operations where fuel economy is not a concern or cruise speeds are typically below 65 mph, gear for an engine speed of 1600 rpm at the 65-mph checkpoint. Gearing combinations that produce an engine speed less than 1500 rpm at the vehicle s intended cruise speed should be avoided. The formula for determining engine speed (rpm) at the 65-mph checkpoint for a selected gearing combination is: rpm = (65 mph) (top gear ratio) (axle ratio) (tire revs/mile) 60 Or log on to www.powerspec.cummins.com for more gearing recommendations. Vocational Gearing Recommendations. The ISM vocational ratings are governed at 2100 rpm to deliver optimal performance with a wide variety of automatic and automated manual transmissions. Follow these simple recommendations to ensure gearing is properly specified: Select a gearing combination that will result in an engine speed between 1700-2000 rpm at the vehicle s intended cruise speed (mph). The gearing combination selected should deliver the minimum startability (shown below) when launching the vehicle in the lowest gear of the transmission. Tractor/Trailer Combination: 20% Straight Truck: 28% The gearing formula for determining engine speed (rpm) at the 65-mph checkpoint for a selected gearing combination is: rpm = (65 mph) (top gear ratio) (axle ratio) (tire revs/mile) 60 Or log on to www.powerspec.cummins.com for more gearing recommendations.
