Japan, China researchers develop plasma-assisted MnO2 filter that produces zero-NO2, -SO2 diesel exhaust

Green Car Congress

This research, published in the journal Separation and Purification Technology , shows that ozone can be used to remove not only SO x but also NO x from fossil fuel combustion exhaust streams. In this study, to improve absorption performance of SO 2 and NO 2 , we added ozone in exhaust gas. Osaka et al.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

In a recent open-access paper published in ACS’ Environmental Science & Technology , researchers from the University of York report that alcohols in windshield washer fluid account for a larger fraction of real-world vehicle emissions than previous estimates have suggested. the products used for “car care,” such as windshield washer fluid.

The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al. Background.

Transient Plasma Systems says advances are bringing plasma ignition technology closer to commercialization

Green Car Congress

Traditional ignition systems when used to enhance internal combustion engine (ICE) efficiency and lower emissions are handicapped with high energy consumption and poor durability leading to an unattractive cost of ownership. For advanced ignition systems to be adopted, cost, size and lower energy consumption are critical.

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 Their paper appears in the ACS journal Energy & Fuels. Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. L) and medium-duty (6.4

Study finds air quality models significantly underestimate traffic as source of NOx in Europe

Green Car Congress

Traffic contributes more to NO x emissions in Europe than previously thought, according to a new study by a team at the University of Innsbruck. Generally, different combustion and exhaust treatment characteristics result in significantly higher NO x /CO 2 emission ratios for diesel powered cars than for gasoline. —Karl et al.

Jacobson at Stanford University. However, climate models to date have mischaracterized the effects of soot in the atmosphere, according to Jacobson, director of Stanford’s Atmosphere/Energy Program. Particle traps filter out soot particles from exhaust fumes. Dessler et al., 2008] and methane [Schutz et al., Guenther et al.,
