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. —Zhao et al.

Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. A key control strategy is to reduce emissions of the limiting reagent.

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

Green Car Congress

Consumer products such as shampoo, cleaning products and paint now contribute as much to emitted volatile organic compounds (VOCs) in cities as tailpipe emissions from vehicles, according to a new study led by NOAA. These products contain organic solvents, which lead to substantial emissions of VOCs to the atmosphere.

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.

CMU study finds SOA levels in cities like LA will remain high despite cleaner cars; nonlinear relationship between SOA and NOx

Green Car Congress

The findings of a study by researchers at Carnegie Mellon University, with colleagues at UC Berkeley, suggest that changing atmospheric NO x levels over the next two decades will likely significantly reduce the effectiveness of stricter new gasoline vehicle emissions standards in reducing concentrations of secondary organic aerosol (SOA).
