Toyota and ExxonMobil Researchers Collaborate to Write Award-Winning SAE Paper

Warrendale, PA - August 10, 2004 - A technical paper elucidating the impact of fuel molecular structure and vehicle technology on emissions has earned the Society of Automotive Engineers (SAE) Harry L. Horning Memorial Award. The award will be presented at the 2004 SAE Powertrain & Fluid Systems Conference & Exhibition on October 25-28 at the Tampa Marriott Waterside in Tampa, Florida.

The award, established in 1938 to preserve the memory of SAE's 1925 President Harry L. Horning, annually recognizes the authors of the best paper relating to the better mutual adaptation of fuels and internal combustion engines presented at a meeting of the Society. This year's winning paper, "Effect of Hydrocarbon Molecular Structure in Diesel Fuel on In-Cylinder Soot Formation and Exhaust Emissions" (paper #JSAE 20030059; SAE 2003-01-1914), researches ways to enable optimization of the entire fuel/engine/aftertreatment system for reductions in diesel system emissions based on the examinations of the changes in both intrinsic chemical reactivity and in-cylinder physical processes when the fuel properties are changed.

This year's award-winning authors, representing Toyota Central Research & Development Laboratories, Inc. and ExxonMobil Research & Engineering Co., include:
