New generation of Ford EcoBoost ethanol injection technology promises additional 10 percent gain in fuel economy

More details are emerging on the next generation of Ford Ecoboost engine technology, that uses ethanol injection to sustain a turbocharged engine at a high compression ratio. High compression increases thermal efficiency of otto engines, and fuel economy.

High compression is not possible with gasoline fuels, but is possible with ethanol injection technology that takes advantage of ethanol’s high octane rating that permits higher compression ratios.

The new generation of EcoBoost, according to a new report, offers up to 10 percent increase in fuel economy over first-generation EcoBoost, which is up to 20 percent more efficient than traditional engines. In Ecoboost, ethanol injection prevents premature detonation, or knock.
