Highly turbocharged alcohol-fueled direct-injection spark-ignition (DISI) engines operated at a high compression ratio could be as or more efficient than diesel engines while also providing advantages of lower vehicle cost, lower emissions and higher power, according to a recent modeling study by Leslie Bromberg and Daniel Cohn at MIT.

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. We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. John Kirwan.

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.

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.

A recent white paper by Leslie Bromberg of MIT’s Plasma Science and Fusion Center and Wai K. There is no strong advocacy for methanol (unlike ethanol) as a transportation fuel; therefore, they said, it has been displaced by ethanol as oxygenate of choice in gasoline blends. It is a safe fuel. Vehicle use and optimization.

As part of an aggressive deployment strategy for improving fuel efficiency across its product line-up in the near-to medium-term, Ford will offer its first-generation turbocharged, gasoline direct-injection EcoBoost engines ( earlier post ) in 90% of its product lineup by 2013. Planning background. ” First-generation EcoBoost.
