MidRange Engines Redefine Efficiency

Cummins ISL9 and ISB6.7 are the unchallenged market-share leaders across virtually all midrange applications. Here’s a quick preview of some of the improvements for 2017 that will keep them a step ahead of the pack.

2017 B6.7
The 2017 B6.7 has a legacy of proven technology and customer satisfaction; 11 million engines have been built over the past 32 years. Whenever new technology is implemented, Cummins thoroughly validates it prior to production. By the time the 2017 B6.7 is launched, the program will have completed 1.5 million miles of testing in multiple real-world applications, especially stop-and-go duty cycles, ensuring exceptional uptime from the start.

Uptime is increased through modifications to the bearing system in the VGT® Turbocharger, the use of Fleetguard® filters with Stage 1 technology, and more. Modifications in combustion technology deliver up to 7 percent better fuel economy in key duty cycles running at lower speeds and in inner-city operations. Ratings range from 200 hp to 325 hp, with up to 750 lb-ft of peak torque.

2017 L9
The Cummins L9 for 2017 is built to handle more demanding duty cycles. Not only does it have the highest power-to-weight ratio in its class, but it is also built using high-strength components and features such as replaceable cylinder liners, which allow for engine rebuilds.

Like its smaller brother, the L9 is highly efficient. Two different rating families will be offered – a high-efficiency series from 260 hp to 350 hp, with its own unique turbocharger, piston design, damper and aftertreatment system, and a high-performance series from 370 hp to 380 hp, for severe-duty truck applications. Of course, both of these engines are available with Connected Diagnostics,™ to help increase uptime by providing a real-time diagnostic link on vehicles with telematics.

That’s how Cummins is redefining efficiency in 2017 for your medium-duty and vocational truck customers. For more information about Cummins B6.7 and L9 engines for 2017, visit:
