Birmingham study finds butanol-gasoline blend reduces GDI engine-out carbonaceous emissions; similar NOx

Green Car Congress

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.

Optimizing Turbo Diesels for Emissions and Performance with 5% and 20% Biodiesel Blends

Green Car Congress

Stock engine design and controls target delivering optimal performance with conventional diesel fuel; this leads, however, to suboptimal results for biodiesel in terms of the BSFC and NO x increases. However, with an energy density 13% lower than diesel (37.5
