Characterizing Emissions from Vehicles and Engines Using Biofuels: An Overview of Selected Canadian Federal R&D Activities

Lisa A. Graham, M.Sc., Senior Chemist, Emissions Research and Measurement Division, Science and Technology Branch, Environment Canada

March 29, 2007
Cal EPA Headquarters, 1001 "I" Street, Sacramento, CA



Environment Canada' Emissions Research and Measurement Division has been active in characterizing the emissions - regulated and unregulated - from engines and vehicles operating on biofuels for the last decade.

The projects undertaken are very diverse, ranging from studying the interaction of advanced heavy duty emissions control technologies with biodiesel to understanding potential impacts of biodiesel source on emissions to evaluating the effect of ethanol blends on current technology light duty vehicles. Unregulated emissions characterization has included detailed speciation of volatile organic compound emissions, including identification of a number of unique species in biodiesel emissions; detailed particulate organic carbon speciation and speciation of homogeneous charge compression ignition (HCCI) engine emissions operating on ethanol blended fuels.

This presentation will provide a brief overview of several recent projects, including key findings and suggestions for further research.

Speaker Biography

Lisa A. Graham, M.Sc., is the Senior Chemist with the Emissions Research and Measurement Division (ERMD) of Environment Canada in Ottawa. She has been with ERMD since 1991. Lisa Graham is an adjunct professor in the Department of Civil and Environmental Engineering at Carleton University and an associate member in the Ottawa Carleton Institute for Environmental Engineering. She also is a member of the Research Management Committee for the AUTO21™ Network of Centers of Excellence.

Lisa Graham completed her Bachelor of Science (honors) in Chemistry at McGill University in 1989 and her Master of Science in Chemistry at Carleton University in 1991. Her research interests include chemical and physical characterization of gaseous and particulate matter emissions from mobile and stationary sources, environmental and health effects of these emissions and the effects of these emissions in micro-environments.
