Comparison of Emission Standards (g/mi). . Cackette was in effect suggesting that the future tailpipe emissions baseline (LEV III) for light duty passenger vehicles—both diesel and gasoline—was likely to be or to approximate CA SULEV/US Tier 2 Bin 2. Current 50-state baseline Projected future baseline. CA LEV US T2B2 CA SULEV.

Proposed by John Heywood and colleagues at MIT in 2005, the basic premise of E85 boosting is that ethanol (or other lower alcohols) suppresses knock due to the large evaporative cooling effect it has on the air-fuel mixture when injected directly into the cylinder, supplemented by ethanol’s inherent high octane number.

A recent white paper by Leslie Bromberg of MIT’s Plasma Science and Fusion Center and Wai K. In comparison, they noted, the technology for bio-chemical ethanol production from cellulosic biomass is not sufficiently developed yet. The toxicity (mortality) is comparable to or better than gasoline. It is a safe fuel.

From a “well-to-wheel” perspective, high efficient gasoline and diesel engines are nearly as energy efficient as any technology available. The quickest and most cost-effective way to achieve our energy usage goals is through faster adoption of fuel-efficient downsized gasoline and diesel engines.
