Heavy-duty diesel engines still power most large vehicles used in the construction, mining and transportation industries in the United States. Engineers are working to improve the fuel efficiency of these engines while minimizing pollution to reduce energy consumption and ensure the sustainability of these industries in the future.

To tackle this problem, researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory joined forces with Caterpillar Inc., one of the world's largest manufacturers of construction and mining equipment. Taking advantage of Argonne's high-performance computing resources, researchers developed a potential piston design for Caterpillar's engines that could improve fuel efficiency while reducing harmful emissions.
