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

Presentation: 1. 2.


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.
