Science Spectrum Magazine Announces Top Minorities in Science, [2005-07-11]
Johney Green, FEERC Group Leader, was recognized as one of the "50 Most Important Blacks in Research Science" for 2004 based on his contributions to automotive research, his highly visible role as a minority scientist, and as a role model to students and others. The "50 Most Important" were featured in the September edition of Science Spectrum magazine. Johney and the other winners were recognized at the Emerald Honors Conference held in Nashville, Tennessee, September 16, 2005. This event celebrates the accomplishments of several minorities in science and promotes their greater representation among science professionals.

Brian West receives presentation award from SAE [2005-06-01]
FEERC staff member Brian West was given an SAE Excellence in Oral Presentation Award for presenting "Time-resolved laser-induced incandescence measurements of particulate emissions during enrichment for diesel lean NOx trap regeneration" at the SAE 2005 World Congress. This is the second time Brian has received this award, in just a short time period. Brian also recieved this award for a presentation he made at the SAE 2004 Fall Powertrain & Fluid Systems Conference.

Jim Parks gives keynote presentation at the 19th North American Catalysis Society Meeting [2005-06-01]
FEERC staff member James E. Parks II delivered a keynote presentation at the 19th North American Catalysis Society Meeting in Philadelpia, held May 22-27, 2005. The presentation was entitled: NOx adsorber catalysis for diesel emission control.
Inaugural Merit Review of Fuels Technology Research held March 7-9. [2005-04-01]
ORNL and NREL organized the inaugural merit review of Fuels Technology R&D projects in the Office of FreedomCAR and Vehicle Technologies (OFCVT). Research was reviewed by an independent panel March 7-9, 2005 in Golden, Colorado, in a format similar to other OFCVT technology areas. The 21 reviewers were primarily from fuel and lubricant companies, automobile manufacturers, and engine companies. There were 24 technical presentations representing the research at DOE laboratories, industry, and universities. Among the reviewed research topics were:
- Summary of fuel sulfur effects on diesel emissions controls, a large activity in recent years which is near conclusion
- Fuel property effects on advanced combustion regimes, an emerging research area
- Experiences with biodiesel utilization
- Natural-gas vehicle studies
- Environmental impacts and unregulated emissions
Members of the Fuels, Engines, and Emissions Research Group made presentations on six projects. At the close of the review meeting, the floor was opened to comments and recommendations that will prove valuable to guiding future efforts in the Fuel Technologies area. The quality and impact of the research, in general, was held in high regard.
Mechanical Engineering magazine feature on diesel engine development cites ORNL researchers and engine lab. [2005-02-01]
The January 2005 issue of Mechanical Engineering, the magazine of the American Society of Mechanical Engineers, contains a six-page article on "A New Dawn for Diesel." The DOE-sponsored study of the market penetration of diesels, conducted by ORNL and Energy & Environmental Analysis, Inc., is cited in the article. A photograph of one of the engine research cells at ORNL is included and refers to the experimental diesel emission control system consisting of an oxidation catalyst and lean-NOx trap. Many industry and university experts in diesel engine development are quoted in the article, which presents an overall positive outlook for one of the Office of FreedomCAR and Vehicle Technologies' key research areas.
FEERC welcomes a new staff member [2005-02-01]
We are pleased to announce that Jae-Soon Choi became an ORNL FEERC staff member effective February 2005. Jae-Soon had been conducting research at ORNL since March of 2003 under a post-doctoral program. We welcome his continuing contributions.
Mini-workshop explores advanced thermodynamics of internal combustion engines [2004-01-10]
Members of the ORNL Fuels, Engines, and Emissions Research Center organized and conducted a mini-workshop on advancing the efficiency of combustion engines. Particular focus was given to the large yet elusive thermodynamic losses characteristic of high-temperature, non-equilibrium flames used in today's engines. A quote from one of the participants, "A flame is a thermodynamic disaster", captures the rationale for studying the phenomenon. As such, the meeting participants included pioneers and recognized authorities in the field of thermodynamic analysis and combustion processes: Prof. David Foster, University of Wisconsin; Prof. Gerald Caton, Texas A&M; Dr. Roy Primus, General Electric (formerly at Cummins); Dr. Dennis Siebers, Sandia National Laboratory; and Mr. John M. Clarke, consultant (retired from Caterpillar).
Potential paths to mitigating the losses were discussed, ranging from new combustion methods, radical intervention in the combustion process, and novel thermodynamic "cycles" that inherently improve the use of the fuel's available energy. Some specific experiments and analytical studies were proposed.
The workshop supports an LDRD project led by ORNL on the subject of stretching the efficiency of combustion-based engines with heavy focus on the combustion process. The project has been encouraged by DOE/Headquarter Office of Freedom Car Vehicle Technologies (OFCVT) as providing important to future guidance in internal combustion engine R&D. The project principal investigators are FEERC Director Dr. Ron Graves and FEERC Senior Staff Member Dr. Stuart Daw. The team expects to carry out analysis and experiments during the next two years to identify and validate the combustion and thermodynamic paths to higher engine efficiency.

Robert M. Wagner wins ORNL Early Career Award [2003-11-25]
UT-Battelle, LLC presented its annual Awards Night honors to outstanding employees November 21. Robert M. Wagner of the Engineering Science and Technology Division's Fuels, Engines, and Emissions Research Group, earned the Early Career Award for Engineering Accomplishment. He was cited for excellence in engineering research on advanced engine controls and novel combustion regimes that are critical pathways for meeting the Department of Energy's dual goals of higher energy efficiency and lower emissions in transportation.
