ERC Wins Role in Multi-Million Dollar project

The Engine Research Center (ERC) is pleased to announce the winning of a competitive program with the U.S. Army’s National Automotive Center (NAC) under the Department of Defense’s Dual Use Application Program (DUAP)¹. The initial program commitment is for three years, and will total 7.21 million dollars, including both Government and industrial partner commitments. A primary objective of this work is to investigate advanced technology within the framework of product-related programs which are of interest to both the Army and industry, and to work as a team to promote product development with both military and commercial application. The ERC teamed with seven engine and component industries in preparing and submitting the proposal for this work. As part of the program, the Department of Defense, under the direction of the Army’s NAC, will essentially match the financial contributions of the ERC’s industrial partners. The advanced technology effort will take place within the ERC, the laboratories of the industrial partners, and the facilities of the Army’s NAC. The overall Government/industry/academia team for this effort will use unique and intimate teams to assure high-quality technology transfer.

1 The Army’s NAC resides within the Tank-Automotive Research, Development and Engineering Center (TARDEC), Tank U.S. Army -Automotive and Armaments Command (TACOM) in Warren, MI.

Professor Jay Martin Becomes New ERC Director
Center Continues Shared Governance Organization Structure

wpe57.jpg (2087 bytes) Professor Jay K. Martin has stepped into the position of ERC director, replacing Professor David E. Foster who held the position since July 1994. Foster continues on the ERC faculty and will serve as advisor to Martin for the next year. The move represents a step in the ERC’s four-year rotational system with faculty serving a year as "apprentice" director before actually assuming the full responsibility as director.

Jay has been with the ERC since 1985 where his primary fields of research have been engine diagnostics, combustion, heat transfer, and fluid dynamics. Much of the research he has conducted recently has been sponsored by the Wisconsin Small Engine Consortium.

The ERC's shared governance style of organization was adopted after Professor Borman's retirement from the ERC director position in 1994. Each faculty member has primary responsibility for one particular aspect of the center's operation, i.e., graduate student recruiting, the seminar series, outreach, the budget, the shop, or capital equipment, etc. Each member reports to the group as a whole at weekly meetings, and members reach consensus regarding issues relevant to the center's operation. After decisions are made as a group, individual faculty have the responsibility of implementing the decision in their areas of responsibility. These responsibilities are regularly rotated among the faculty.

Kevin Hoag is Named to New ERC Post

UW Alum Kevin Hoag has been appointed to a new academic staff position with responsibilities in both administration and coordinating research operations as well as assisting the ERC director. Hoag most recently was senior technical advisor for continuing engineering education at Cummins Engine Company, Inc. in Columbus, Indiana. During his 16 years there, the department he led won the Glenn L. Martin Award for Corporate Leadership in Continuing Education, presented by the International Association for Continuing Engineering Education. Hoag received both his BS and MS degrees in mechanical engineering from UW-Madison. He did his graduate work with Professor David E. Foster.

ERC Faculty, Staff, and Student News

Professor David E. Foster received an oral presentation award for the paper, "Exploring the Limits of Improving DI Emission by Increasing In-cylinder Mixing," at the International SAE Fuels and Lubricants meeting in San Francisco in October 1998. Graduate student Eric Kurtz was the main author and Foster was the co-auther.

Foster continues his work as a committee member of the National Committee to Review the Partnership for a New Generation Vehicle. The committee is commissioned by the National Academy of Science and organized through the national Research Council.

Assistant Professor Jaal B. Ghandhi will receive the Teetor Education award at the spring SAE meeting. This award, from the SAE Ralph R. Teetor Educational Fund, is focused on young engineering educators and encourages them to meet an exchange views with practicing engineers at SAE events and meetings.

Professor Rolf D. Reitz was recently appointed Wisconsin Distinguished Professor by the University of Wisconsin system. The award includes research funding of $25,000 each year for five years.

ERC graduate Dr. Herman Snyder was awarded the Best Student Paper Award at the Institute of Liquid Atomization and Spray Systems meeting in

Sacramento in May 1998 for the paper, "20/20 Atomization—Using MEMS to Obtain 20 Micron Sprays with Low Pressure air (20 psig.)," by Snyder, H. and Reitz, R.D. which was presented at the 10^th Annual Conference on Liquid Atomization and Spray Systems in Ottawa, Canada, May 18-21, 1997.

Associate Professor John J. Moskwa will receive a $290,000 grant from Ford Motor Company in England to examine ways of minimizing the emissions of the modern diesel engine system through improved synthesis and optimization of combustion processes, aftertreatment systems, and system controls. A second high-bandwidth transient engine dynamometer will be set up in the Powertrain Control Research Laboratory using these funds.

Eric Kurtz has been awarded the 1998-99 SAE/Vanmar Scholarship for $1,000 for each of two years. The scholarship rewards students doing research in the area of automotive engineering.

The ERC will host an Engine Symposium entitled "The Next Fifty Years of Engine Research" in Madison on June 10 and 11. The meeting will also celebrate 10 years of funding at the ERC as the U.S. Army's Center of Excellence in Engine Research. Speakers will include internationally recognized experts in engine research. For more information, please call 608:263-2735 or consult the ERC webpage, http://www.erc.wisc.edu/

The SAE Small Engine Technology Conference Exposition will be held September 28-30 in Madison at the Marriott West. To get more information, check the ERC webpage (see above).

Powertrain Control Research Laboratory Receives National Award

At the 1998 Global Powertrain Congress held at Cobo Hall in Detroit this past November, members of the Powertrain Control Research Laboratory received an award for best powertrain innovation. The "Powertrain Excellence Award" was presented to Associate Professor John J. Moskwa and graduate students Guy Babbitt and Steven Seaney for their research and development of the "Very-High Bandwidth Transient Engine Dynamometer (400 Hz)." This system is the highest bandwidth transient engine dynamometer of its size in the world, and it has been under development for about six years. Other key contributors to this project include Darren Bisaro, Rich Bonomo, Rob

Pape and Pat Scharf, along with Ford Motor Company's support of PCRL laboratory development. For additional information about the project, check the lab's webpage and the Research site at:
