An engine that is 30 per cent more efficient than a conventional gasoline engine has been designed by researchers at the Massachusetts Institute of Technology. They developed a way to inject ethanol into the combustion chamber during acceleration. This cools the air-fuel mixture, making it possible to increase the compression ratio and add a turbo charger without causing damaging engine knock. That meant they were able to build a smaller,
