Seminar: Motor Vehicles and Air Quality: Assessing Particulate Matter Emissions

Center for Automotive Research SAE Industrial Lecture Series

Abstract

Motor vehicles have been recognized already since the 1950s to contribute to urban smog. Regulations by the California Air Resources Board and the Clean Air Act ushered in modern three-way catalyst-equipped vehicles to combat urban ozone. Then in the 1990s epidemiological studies raised concerns about potential health associations with particulate matter (PM10 and PM2.5). Particulate matter is a physically and chemically heterogeneous substance; thus, a good understanding of its properties is necessary to implement effective emissions aftertreatment and to understand how this impacts the atmospheric impact of vehicle emissions.

This lecture aims to provide a fundamental basis for understanding how particulate matter originates in combustion engines, the physical and chemical nature of particulate matter emissions and the issues involved in measuring these emissions.

About the speaker

Matti Maricq is a technical leader in the Chemical Engineering and Emissions Aftertreatment Department at Ford Research and Innovation Center. He currently heads the Vehicle Emissions Research Laboratory. This is a chassis dynamometer facility which is set up for state of the art vehicle exhaust measurements. It provides Ford's research engineers the tools to investigate the effectiveness of new engine and aftertreatment technologies to reduce emissions of gaseous and particulate pollutants.

Matti has been at Ford for 21 years. He received a PhD in physical chemistry from the Massachusetts Institute of Technology. Matti’s research efforts focus on the investigation of particulate matter emissions from motor vehicles and include the aerosol physics behind particulate matter emissions and measurement, soot formation in flames and engines, characterization of combustion particulate matter and the development of better particulate matter sampling and measurement methodologies.
