New Technology Diesel Engines: Exhaust Emission Control and Animal Toxicology Study
John C. Wall, Sc.D., Cummins, Inc., Indiana, and Jacob McDonald, Ph.D., Lovelace Respiratory Research Institute, New Mexico
February 28, 2012
Cal EPA Headquarters, 1001 "I" Street, Sacramento, CA
This presentation will review the evolution of U.S. diesel engine design over the past two decades in response to emission regulations, will focus on emission control technology and its impact on emissions mass and chemical composition from New Technology Diesel Engines (NTDE) in some detail, and will present an update on the first animal toxicology study conducted on NTDE: the Advanced Collaborative Emissions Study (ACES). ACES is an industry/government sponsored program developed to characterize the composition and toxicity of new technology diesel emissions. The ACES results have been peer reviewed by the Health Effects Institute (HEI) and are scheduled to be publicly available in April.
In addition, a clean diesel technology demonstration and display will also be taking place from 10 am - 4:30 pm on 11th Street between H and I and adjacent to the Cal/EPA building.
John C. Wall, Sc.D., is Vice President and Chief Technical Officer, Cummins Inc., Columbus, Indiana, and is responsible for Cummins global research and engineering organizations and energy and environmental policy. Dr. Wall studied mechanical engineering at the Massachusetts Institute of Technology, where he received his SB and SM in 1975 and ScD in 1978. He serves on advisory councils for Purdue University, HEI, the MIT Energy Initiative, Indiana University. He has served as an industry advisor to the California Air Resources Board (ARB) and is currently a member of the USEPA Mobile Sources Technical Review Subcommittee. Dr. Wall is a member of the National Academy of Engineering and a Fellow of the Society of Automotive Engineers. Dr. Wall has been awarded the SAE Horning Memorial Award and Arch T. Colwell Merit Award for research in the area of diesel fuel effects on emissions.
Jacob McDonald, Ph.D., is a scientist and Director of the Environmental Respiratory Health program at the Lovelace Respiratory Research Institute. He received his PhD in Environmental Chemistry and Toxicology from the University of Nevada, Reno. Dr. McDonald is the principal investigator of the animal toxicology component of the ACES studies. Dr. McDonald has over 100 publications on inhalation toxicology and atmospheric chemistry and oversees the inhalation department at Lovelace. Dr. McDonald is on the advisory panels of the USEPA Clean Air Centers at Harvard University and Michigan State, has served on several panels for the USEPA, the National Academy of Sciences, and is currently on the International Agency for Research on Cancer (IARC) panel that is defining the cancer potential for gasoline exhaust, diesel exhaust, and nitroarenes.
