TURIN, ITALY … Power management company Eaton has expanded its SmartAdvantage Powertrain range to meet truck manufacturers’ growing demand for weight reduction and fuel efficiency. The new range has been designed to suit Cummins’ ISX12 diesel engine applications of up to 49 tonne gross vehicle weight (GVW). Now available globally, Eaton’s SmartAdvantage will be presented in Europe for the first time at the IAA show in Hannover, Germany.
Building on the success of the SmartAdvantage Powertrain for Cummins’ ISX15 engines, the expanded SmartAdvantage package integrates Eaton’s Fuller Advantage™ Series 10-speed Automated Manual Transmission with the ISX12 diesel engine. As such, it is available as a small-ratio-step overdrive model with two new Cummins ISX12 SmartTorque2 (ST2) ratings: the ISX12 370ST2, with torque of 1559-1966 Nm, and the ISX12 425ST2, with torque of 1830-2237 Nm.
Thanks to a combination of hardware and software enhancements, the new powertrain package can achieve an estimated two to four percent fuel efficiency improvement in regional haul applications. Additionally, its optimised engine and transmission communications and new control logic enable further engine downspeeding in the overdrive position and the effective use of direct-drive technology.
With no cooler needed, Eaton’s Fuller Advantage Series transmissions ensure low overall weight and improved reliability. By combining an aluminum rear transmission housing, range cylinder, shift bar housing and shift tower with a thin-wall cast-iron main case design, the transmissions weigh 37.2 kg less than Eaton’s UltraShift® PLUS LAS base model. The new Precision Lubrication system for precise and efficient transmission lubrication further enhances fuel economy by reducing churning losses.
Cummins new ISX12 engines with next generation ST2 ratings effectively manage the power needed for the load demand. Thanks to its patented electronic feature Vehicle Acceleration Management (VAM), Cummins’ engines manage vehicle acceleration for smoother shifting, contributing to fuel economy in stop-and-go duty cycles common in regional haul applications.
“Cummins and Eaton continue to collaborate on powertrain solutions for the global on-highway markets that we serve,” said Lori Thompson, Cummins vice president – Truck and Bus OEM Business. “The latest SmartAdvantage Powertrain offerings are a natural extension of the initial product, and will provide customers with the fuel economy and productivity improvements they desire, along with a broad range of applications to meet their specific hauling needs.”
“The level of integration and advanced technology in the SmartAdvantage Powertrain delivers a package that both fleet owners and professional drivers are thrilled with,” said John Beering, senior vice president and general manager – Commercial Vehicle Transmission Business, Eaton. “Our teams continue to receive feedback from our customers and, in turn, deliver the kind of integration between the transmission and engine that is best-in-class in the global heavy-duty truck market.”
