How do you “redefine” a company that for decades has manufactured diesel engines? It takes “customer focused innovation,” Cummins officials said during a news conference here Tuesday.

Vice President of North American Engine Business Amy Boerger explained, “Cummins products are demonstrating leading fuel efficiency, proven durability and superior performance that help enable our customers’ success across the diverse applications they operate.”

A demonstration tour to tout the company’s latest was announced at the Mid-America Trucking Show. At an offsite event, Vice President of Engineering, HMLD Engine Business Jim Fier explained that recent regulatory changes have pushed manufacturers of heavy duty equipment into a reactionary mode, working to meet, for example, new Environmental Protection Agency (EPA) standards several times during the past decade. “Today,” he said, “we’ve gotten ahead of that curve and we’re focused on the unique needs of our customers.

Fier was recently promoted from his prior position as Executive Director of HMLD Highway at Cummins. Boerger, previously Executive Director of North American Engine Business at Cummins, was also recently promoted.

The upcoming Cummins Redefining Tour, described as a “mobile showcase” of Cummins products and technology, will feature a fleet of tractors from a variety of manufacturers and all powered by the Cummins ISX15 power plant, kicks off this summer.

Boerger explained that touring demonstrations of Cummins products is far from a new concept. In 1931, company founder Clessie Cummins installed a Model U diesel in a truck chassis manufactured by the Indiana Truck Company and drove it across the United States. The coast to coast run spanned 3,214 miles, and was completed on $11.22 worth of fuel. Cummins makes no claim that their current engines can achieve a similar fuel costs.

Several 2017 model engines will be on display during the tour, including the 2017 ISX15 engine that Cummins introduced at MATS. The engine will produce from 400 to 605 horsepower, the company claims, and will be offered in two distinct ratings groups. Customers will choose between one configuration designed to maximize fuel economy and a second version that maximizes power.

The company’s current ISX15 offering is benefiting from advances in technology, too. The 2015 version features NanoNet oil filtration that the company claims provides best-in-class particle removal, providing superior protection and filter life.

The Diesel Particulate Filter (DPF) cleaning interval has been extended to 400,000 miles for line-haul applications that average better than 5.5 mpg. The goal, Boerger said, is a lower overall cost of ownership.

At the MATS event, the Cummins talked up its ADEPT suite of engine enhancements that uses load, speed and grade sensing technology to initiate adjustments to speed, power and selected gear, taking advantage of vehicle momentum for improved fuel economy. SmartCoast is a feature that disengages the vehicles driveline when the vehicle is coasting downhill, reducing drag on the vehicle caused by driveline friction. The feature allows the engine to idle while coasting. Drivers who are familiar with the “Georgia Overdrive” chronicled in Dave Dudley’s famous “Six Days on the Road” hit from the 60’s will undoubtedly smile at the function of the SmartCoast feature. The difference, of course, is that the truck is never in neutral with the SmartCoast feature and engine braking can be applied as needed.

Another innovation, dubbed “SmartTorque2,” which manages torque to eliminate unnecessary downshifts and keep the engine operating at the most efficient RPM.

Also redefined, or simply refined, is the company’s Single Module exhaust aftertreatment system from subsidiary Cummins Emissions Solutions. Thanks to advancements in catalyst technology and advancements in urea dosing, the Single Module system saves 60 percent in space requirements and weighs 40 percent less than current technology.

Finally, the manufacturer introduced Cummins Connected Diagnostics, a system that works with leading telematics suppliers to provide instant updates of fault codes and other vehicle issues. A Cummins representative provides expert diagnosis of engine faults which can be communicated in a manner that works best for the customer, including the customer’s dispatch management software.
