Cummins and Eaton Partner on SmartAdvantage Powertrain, Improved Fuel Economy
Cummins, a leading diesel engine manufacturer, and Eaton,® a leader in heavy-duty transmissions, have joined forces to introduce SmartAdvantage™ Powertrain.
The SmartAdvantage Powertrain with the ISX15 will be available in applications up to 110,000 lb gross vehicle weight (GCW).
Additionally, the Cummins ISX12 diesel, which is ideal for regional-haul applications, is part of the expanded offering of the SmartAdvantage Powertrain.
These totally integrated units take the efficiency of Cummins ISX15 and ISX12 with SmartTorque2 (ST2), and combine it with the smooth-shifting Eaton Fuller Advantage™ 10-speed Automated Transmission, for 3-6% better fuel economy for the ISX15 and 2-4% better fuel economy for the ISX12.
Cummins ISX Engines With SmartTorque2
ST2 automatically senses vehicle weight, grade and operating gear, then selects the optimum torque for the best combination of fuel economy and performance in every gear. The closestep ratio, combined with SmartTorque2, provides a balance of performance, delivering power when conditions demand it,such as steep road grades, heavy loads and cruise speeds above 65 mph (105 kph).
These engines come with Vehicle Acceleration Management (VAM), a unique electronic feature that maintains a moreconsistent acceleration rate and more efficient transition through the gears, reducing driveline wear and adding fuel savings.
Eaton Fuller Advantage 10-Speed Automated Transmission
Features of the Eaton Fuller Advantage 10-Speed Automated Transmission include the strategic use of lightweight components and Precision Lubrication. Small-step technology enables downspeeding in overdrive and efficiency in direct drive.
Optimized shifting is based on grade, vehicle weight, engine torque and throttle position. Fuel economy is further enhanced through Precision Lubrication, which reduces churning losses and eliminates the need for a cooler in applications up to 80,000 lbs (36,287 kg) GCW.
