E100 Engines and Vision

 

 


An E100 engine is basically an E85 engine that has had its compression ratio raised to to take advantage of ethanol's high octane and built with direct injection (DI) and turbo charging to ensure starting in cold weather and maximum mileage. (By tuning the power level, Les MacTaggart of the Indy Racing League believes equivalent or better mileage to gasoline can be obtained with E100 at the same power level.  Click here to view article.

It would costs only $70 - $100 more to make an E100 direct injection engine flex/fuel engine than it does to make a direct injection gasoline engine. 

The auto companies have made mulit-port fuel injection engines capable of burning E100 in Brazil for many years.  It would be a straightforward process to go to direct injection and make them available in the US. One auto manufacturer has already started selling vehicles with direct injection E85 engines.

Developing an E100 DI engine could easily be done using the same engine lines as we have now.

There would be no huge new capital investment necessary and no years of further research.

Since these engines would perform better than gasoline using E100 (the reverse of the current situation with E85), the retail franchisees would be more willing to invest in the ethanol equipment. Many are reluctant to install E85 since they fear they won't sell enough to recoup their investment.

Price of the E100 fuel would be controlled by the ethanol companies, not the oil companies. This would benefit the consumer through price competition for motor fuel for the first time in the history of the United States.

Companies such as MAHLE Powertrain, Sturman Industries, John Deere, HP2G, Nissan, AHL-Tech, MCE-5 and Ricardo have all made significant advances in  engine technology to permit optimized ethanol engines while still being able to burn gasoline.

Just as in the case of seat belts and airbags, however, this engine technology is not going to come into production on any sort of rapid timetable without a government mandate.

A government mandate that at least 50% of all new vehicles sold in the US be E100 capable with EPA mileage equivalent to the equally powered gasoline engine by the end  of 2016 would make us independent of imported oil in short order and dramatically lower CO2 emissions.
