Ethanol's high octane value could help the U.S. achieve its increasingly stringent fuel economy standards by powering high-efficiency internal combustion engines, according to a study conducted by AVL and partially funded by ICM. E30 gives a higher octane performance than iso-octane, the reference for 100-octane fuel, the study found. "These real-world results show that ethanol blends have the potential to offer much more octane value than previously estimated by methods prescribed by the [American Society for Testing and Materials]," said Steve Vander Griend, head of ICM's research and development of ethanol engines.
