Established in 2008, this award recognizes outstanding accomplishments and leadership in the area of diesel engines. Two awards are given each year, one for Best Paper and the other, the Diesel Engine Research Medal, given to an individual for outstanding leadership in research and development in the field of diesel engines through a singular accomplishment or lifetime achievement. The Best Paper award recognizes the authors of an original and outstanding technical paper presented at an SAE meeting on the subject of diesel engines in the on- or off-road industries. Preferably the paper will be published in an SAE Journal and must address research advancements in diesel engines regarding efficiency and low emissions achieved by innovative experimental and modeling research of the engine, fuel and/or after treatment systems. Oral presentation scores must also be above average.
