Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

Their study is publishedin the ACS journal Environmental Science & Technology. This study aims to better characterize the toxicity of PM from GDI vehicles and the potential for catalyzed GPFs to reduce this toxicity. In the study, the team used two MY 2016 passenger cars. In the study, the team used two MY 2016 passenger cars.

Study Assesses Product Attribute Trade-offs and Technological Progress; Meeting Proposed Obama Fuel Economy Standards Will Require Downsizing and Change in Fleet Mix

Green Car Congress

Christopher Knittel, of the UC Davis Department of Economics and Institute of Transportation Studies, developed a model to examine the technical relationship between vehicle weight, engine power and fuel economy—to which he refers as a production possibilities frontier (PPF)—and how this PPF shifts out over time. Knittel, 2009.

Study Finds That Tripling US LDV New Fleet Fuel Efficiency by 2035 Through Evolutionary Change is Ambitious But Doable

Green Car Congress

The study, “A Fuel Efficiency Horizon for US Automobiles”, was prepared for The Energy Foundation. The study examines how far automobile efficiency can be taken if it is pursued with determination, using an analysis that assumes success in technology and design strategies that offer “revolution by evolution.”
