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.

New statistical method to detect ozone pollution hot spots and monitor instrument failure; combining PCA and MEWMA

Green Car Congress

A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. Ozone is the reactive form of oxygen that contains three atoms per molecule (O 3 ) rather than the normal two.

CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). The test fleet showed statistically significant effects for some pollutants, but not for others.

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. Using statistical methods, the scientists infer emissions from these data within a radius of about one kilometer of the measurement location. We record 36,000 data points per hour.

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

Green Car Congress

The study, by a team of researchers from Carnegie Mellon University, University of Georgia, Aerodyne Research, California Air Resources Board (ARB), Ohio State University, UC Berkeley, and UC San Diego is published in the ACS journal Environmental Science & Technology. We estimate ozone and SOA formation potential.
