You can now spec International medium-duty and vocational truck models with the Allison Transmission FuelSense fuel-efficiency package. Available in 1000, 2000, 3000 and 4000 series transmissions, it automatically adapts shift schedules and torque, maximizing transmission efficiency based on load, grade, and duty cycle.
Allison’s internal testing shows FuelSense cuts fuel consumption by up to 20% depending on duty cycle and application, says Navistar.
FuelSense features are incorporated in part or completely in three levels: FuelSense Basic, FuelSense Plus, and FuelSense Max. All features are available in the 3000 and heavy-duty 4000 series and will be available in the 1000 and 2000 series transmissions later this year.
FuelSense features include fifth-generation smart controls, acceleration management, and a precision inclinometer. Its EcoCal shift technology is said to keep engine speed at the most efficient level, and a feature called ‘Dynamic Shift Sensing’ automatically senses when low-engine-speed shifts can be made. The transmission eliminates the load on the engine when the vehicle is stopped by shifting to neutral, which also serves to reduce fuel consumption and reduce emissions.
The targets here are operators who work in high-density city environments or have demanding start-and-stop duty cycles but also want fuel-economy improvements, says Navistar.
FuelSense is available in the International TerraStar, DuraStar, WorkStar, and PayStar.
