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. Cliff et al.

São Paulo study finds concentration of ultrafine particulates rose by 1/3 in switch from ethanol to gasoline

Green Car Congress

Geiger and Alberto Salvo, an associate professor of economics at the National University of Singapore, led the study—their second with São Paulo big data. Officials, Geiger said, will need to weigh the increase in ozone against the decrease in nanoparticles when ethanol is used. are not regulated.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Gasoline is stored in closed, hopefully airtight, containers and the VOCs in gasoline are burned for energy.

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

Green Car Congress

Advanced ignition technologies, such as those offered by TPS, have been widely recognized as enablers to achieving higher combustion efficiency and lower emissions for gasoline-powered engines. The keys to commercialization have been demonstrating cost, size and optimized energy consumption in line with automotive requirements.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). Dashed lines show US average emissions. Credit: ACS, Tessum et al.

Study uncovers role of longer-chain unburned hydrocarbon emissions from diesels in London air pollution; calls for regulatory shift

Green Car Congress

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London.
