A team at the University of Birmingham reports that a blend of 33% v/v of butanol in EN228 commercial gasoline containing 5% of ethanol (B33) reduces GDI (gasoline direct injection) engine-out carbonaceous emissions, while maintaining similar levels of NO x emissions when compared to standard gasoline combustion at low and medium engine loads.

However, the relative toxicity of biodiesel emissions compared to petroleum diesel remains unclear. OP in oxidized aerosols, including engine exhaust, is commonly quantified using the DTT (dithiothreitol) assay. Error bars are one standard deviation from the mean, letters indicate statistical similarity. Click to enlarge.
