Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

The researchers say that their findings, recently published in an open-access paper in the journal Science Advances , are key to understanding how the universe evolved with the growth of carbon compounds. That insight could also help the car industry make cleaner combustion engines. Zhao et al.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The reasons were two-fold: (i) increased air pollution led to households staying indoors more to mitigate the pollution impact; and (ii) PM 2.5 pollution led to the closing of windows, and running of air-conditioners and air purifiers more intensively either to reduce indoor particle levels or provide relief from indoor heat.

Ice core data show why air pollution is dropping more slowly in US and Western Europe despite lower sulfur emissions

Green Car Congress

The air in the United States and Western Europe is much cleaner than even a decade ago. A new study led by Tokyo Institute of Technology (Tokyo Tech), Hokkaido University and the University of Washington explains why. —co-author and leader of SE-Dome ice core project Yoshinori Iizuka, Hokkaido University.

CU Boulder study: routine household activities generate air quality on par with major polluted city

Green Car Congress

Cooking, cleaning and other routine household activities generate significant levels of volatile and particulate chemicals inside the average home, leading to indoor air quality levels on par with a polluted major city, according to a study by researchers at the University of Colorado Boulder.

Auburn University leads $2M DOE Co-Optima project to evaluate renewable butyl acetate as diesel fuel additive

Green Car Congress

Auburn University researchers are leading a $2-million US Department of Energy Co-Optima project ( earlier post ) that will evaluate renewable butyl acetate (BA) as a bio-based fuel additive that can be blended with diesel fuel to reduce soot and greenhouse gas emissions and yield cleaner engine operation in cold-weather conditions.

EU research project IDEALFUEL seeks to develop marine low-sulfur heavy fuel oils from biomass; Bio-HFO

Green Car Congress

The use of heavy fuel oils (HFOs) contributes to global warming due to the fossil origin of these fuels and, moreover, generating non-negligible emissions of pollutants such as sulfur oxides. Although cleaner fuels are available, many companies opt for HFOs due to their low cost. The participants are Vertoro B.V. (NL);

MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

Engines that could be deployed in the relatively near term could also use high rpm operation and /or water injection, to allow operation with a very small amount of alcohol in addition to a low concentration mixture such as E10 (or possibly with no additional alcohol). Ethanol or methanol would be employed to increase knock resistance.
