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.

All biofuels must meet high standards for reduction of greenhouse gas emissions over their entire lifecycles (growing, processing, and combustion) in order to qualify for the content mandate. However, the EPA’s analysis of lifecycle emissions from biofuels are based on a model whose calculations are highly dependent on vague assumption.

When used in diesel engines, biodiesel usually exhibits several combustion-related advantages, including reductions in CO, UHC and PM emissions, as well as a net CO 2 reduction. The ability to produce emission and noise decreases were subsequently leveraged to produce BSFC reductions. Tags: Biodiesel Diesel Emissions Engines.
