Cummins, Eaton Team On Powertrain Package
Eaton and Cummins unveiled a new powertrain package for the North American heavy-duty truck market that the companies expect to deliver a 3 to 6% fuel economy improvement, lower preventive maintenance costs, and total lifecycle cost improvements. The new product combines an Eaton Fuller Advantage Series automated transmission with new Cummins ISX15 SmartTorque2 ratings. The product will be available in the fall of 2013 for linehaul, regional haul and less-than- truckload (LTL) applications.
The Eaton Fuller Advantage Series automated transmission will be offered as a small ratio step Over-Drive model with new Cummins ISX15 SmartTorque2 ratings: the ISX15 415 ST2, with torque of 1450 lb. ft to 1650 lb.ft and the ISX15 450 ST2 with torque of 1550 lb. ft. to 1750 lb.ft.
Through a combination of hardware and software enhancements, the Cummins and Eaton said the powertrain package benefits include integrated power, fuel and shifting strategies to provide the improved fuel economy in linehaul and regional haul applications. Otimized engine and transmission communications and new control logic enable further engine downspeeding in the overdrive position and the effective use of direct drive technology provide improved efficiency, the companies said.
The new powertrain package is currently undergoing field testing with various sized fleets and initial testing and customer validation results are confirming the fuel economy improvement, Cummins said. Service support will be offered through Eaton's Roadranger program and the Cummins network when the powertrain package goes into production this fall.
