The technology is designed for refuse collection vehicles, with their stop-start operations, and builds on the proven performance of Allison’s earlier FuelSense technology.
New DynActive Shifting uses an algorithm to select the most efficient shift points from an infinite number of combinations based on customer specifications and engine fuel map, as well as vehicle and environmental parameters, while an improved Neutral at Stop function reduces the load on the engine during low-speed coasting, as well as when the vehicle is stationary.
In addition, enhanced Acceleration Rate Management helps to mitigate aggressive driving by automatically controlling engine torque, with five levels of control. Newly updated and exclusive to FuelSense 2.0 Max, there is also the option to limit vehicle acceleration to a customised calibrated rate for more precise control.
As well as being available as standard on all new chassis, the technology can also be retrofitted.
Ashley Brooks, area director at Allison Transmission, says: “Rather than relying on fixed points on a shift table, the learning algorithm used by FuelSense 2.0 continuously finds the ideal balance for the duty-cycle, meaning vehicles operate as efficiently as possible at all times.
“Dennis Eagle customers will also benefit from the premium functionality of FuelSense 2.0 Max, which offers the added advantages of fuel savings during low-speed coasting and custom Acceleration Rate Management.”
Keith Day, engineering director at Dennis Eagle, says of FuelSense 2.0: “It is perfectly suited to the stop-start nature of refuse collection, and also lends itself well to other fleet applications. This makes it an ideal solution for our Urban Safety Vehicle range, which includes products for the construction and logistics sectors.”
