Cummins announced fuel-efficiency improvements, a new engine rating, and Connected Diagnostics at MATS.
The company offers optimized ratings for its 15-liter ISX15 engines. For the most fuel-conscious fleets, the ISX15 is available with ratings of 400 to 450 hp, which deliver peak torque at 1000 rpm. All ratings can be uniquely tailored with electronic features like Load-Based Speed Control (LBSC), Gear-Down Protection (GDP), and Vehicle Acceleration Management (VAM) to maximize fuel economy and reduce overall operating costs.
Since 2010, numerous improvements have been made to the ISX15 to deliver up to 7% better fuel efficiency, Cummins says. Customers moving from a pre-2010 engine could experience an improvement up to 10%. Over just the past three years, there have been significant gains in combustion optimization, reduced parasitic loads, enhanced low-end torque to support downspeeding, and the addition of a naturally aspirated air compressor.
Cummins also announced the introduction of a new ISX15 560-hp rating, with 1850 lb ft of peak torque, replacing an older equivalent rating. Ideally suited for customers operating with heavy loads or on routes with steep grades, the ISX15 560 provides excellent prolonged low-end torque, delivering peak power sooner and over a wider rpm range.
Then there’s the company’s first foray into telematics. Connected Diagnostics is a new application being designed to work seamlessly with many leading telematics systems. Cummins says it will provide customers with expert recommendations for the best action to take when a driver is alerted to an engine system fault. It’s said to be the first of several telematics-assisted applications that Cummins is developing.
Within moments of a fault code being presented, Cummins will be able to analyze fault information, identify the most likely root cause, and provide a recommended action.
Cummins Connected Diagnostics will be available in limited production later in 2014, with full production release planned for 2015.
