Comparison of O 3. Japan) report in the journal Angewandte Chemie the development of a mesoporous two-line ferrihydrite (2LFh)—ferrihydrite is a widespread mineral composed of iron, oxygen, and water—that could lead to a new generation of ozone filters in electrostatic devices and aircraft applications.

Reduction in diesel carbonyl emissions using F-T fuel from coal

Green Car Congress

Other research has shown that carbonyls directly influence physiological response to diesel exhaust particles and can also contribute to secondary organic aerosol formation. In the Tianjin study, they team fueled a four-cylinder light-duty diesel engine fueled with CFT and DF, identifying 13 individual carbonyl compounds in the exhaust.

million metric tons of avoided ozone-related yield losses of major food crops; $US0.6-2.4 While reductions in particulate matter tend to produce local health benefits, the scientists found health and agricultural benefits from reduced ozone disperse more widely. In comparison, the Northern Hemisphere has warmed by about 0.3°C

Comparative study finds that B20 increases emission rates of a number of pollutants in both light- and medium-duty diesel engines at idle

Green Car Congress

A new study led by researchers at the University of Michigan compared regulated and unregulated emissions from both light-duty passenger car (1.7 They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment technology.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

In this study, we present a comprehensive database of emissions from a fleet of GDI- and PFI-equipped light-duty gasoline vehicles tested on a chassis dynamometer over the cold-start unified cycle (UC). We estimate ozone and SOA formation potential. Finally, we analyze the potential climate effects of switching a PFI to a GDI fleet.
