Cummins Inc. made announcements of fuel-efficiency improvements, a new engine rating and Connected Diagnostics. For the most fuel-conscious fleets, the ISX15 is available with ratings of 400 to 450 HP, which deliver peak torque at 1,000 rpm. All ratings can be uniquely tailored with electronic features like load-based speed control, gear-down protection and vehicle acceleration management to maximize fuel economy and reduce overall operating costs, the company explained.
ISX15 SmartTorque2 (ST2) ratings are available with the SmartAdvantage Powertrain, which delivers an additional 3% to 6% fuel-economy improvement. Jointly developed by Cummins and Eaton, the SmartAdvantage Powertrain integrates the Eaton Fuller Advantage Series automated manual transmission and Cummins ST2 ratings to operate the engine in the fuel-economy “sweet spot” and deliver excellent low-end torque and precise shifting, to help every driver perform like the best driver in the fleet.
Cummins also announced the introduction of the new ISX15 560 HP rating, providing customers with the ability to further maximize productivity in their operations. Ideally suited for customers operating with heavy loads or on routes with steep grades, where pulling power and effective engine braking are critical, the ISX15 rating with 560 HP and 1,850 lb.-ft. of peak torque provides excellent prolonged low-end torque, delivering peak power sooner and over a wider rpm range.
Cummins provides more customer support with the development of Connected Diagnostics, a new application being designed to work seamlessly with leading telematics systems. Cummins Connected Diagnostics will provide customers with expert recommendations for the best action to take when a driver is alerted to an engine system fault. Cummins Connected Diagnostics will be available in limited production later in 2014, with full production release planned for 2015.
