Ethanol injection for cars? MIT team thinks so

BOSTON - Injecting small quantities of ethanol into car engines at moments of peak demand -- such as accelerating sharply or climbing a steep hill -- could improve the fuel economy of gasoline engines by 20 percent to 30 percent, according to MIT scientists.

A team of researchers at the Massachusetts Institute of Technology is working on the system, which scientists say would allow carmakers to use smaller engines in their vehicles, reducing weight and improving fuel economy at a lower cost to consumers than by adding a hybrid engine.

“To have a big impact on reducing oil consumption, one needs a low-cost way of improving efficiency, so a lot of people buy the car,” said Daniel Cohn, senior research scientist at MIT in Cambridge, Mass.
