Diesel and the path to a carbon neutral future


Diesel engines will continue improving in the coming years, playing an important role in efforts to further reduce greenhouse gases (GHGs) and atmospheric pollutants, according to a Cummins leader participating in a recent panel discussion on the technology’s future.

Dr. Wayne Eckerle, Vice President – Research and Technology, told the audience at the virtual event sponsored by the Diesel Technology Forum that initiatives such as SuperTruck II are already underway to explore increasing the efficiency of modern diesel engines and long-haul tractor-trailers.

Potential innovations include advances in waste-heat recovery, engine controls, reducing engine friction, aerodynamic vehicle design and much more.

Over time, Eckerle said there will be a growing connection between the entire vehicle and environmental conditions, including advances in “look ahead” technology that enables in-use adjustments for peak fuel efficiency, which translates into reduced GHGs.

“It’s really our equivalent to the space program,” Eckerle said of the SuperTruck program, a public-private partnership led by the U.S. Department of Energy (DOE) and leading companies in on-highway heavy-duty transportation. “That’s how I look at it.” 

SuperTruck I was launched in 2010 with the goal of improving freight hauling efficiency by 50%. It ended up exceeding that goal and many of the initiative’s advances are in mass production today. SuperTruck II aims to increase freight hauling efficiency even more.
