Can FFV and small engines run on hydrous ethanol?
All internal combustion engines and FFVs can run on hydrous ethanol blends. Theoretically, the 4% increase in water content for hydrous ethanol could increase fuel efficiency in comparison with using anhydrous ethanol blends in either unleaded gasoline or in FFV engines. A significant economical advantage of using hydrous ethanol is the ability to utilize this fuel efficiently in any internal combustion engine including small engines and 2-stroke engines. Subject to verification, hydrous ethanol could lower emissions for small engines and two cycle engines. Complying with emissions standards is a major concern for increasing ethanol blends for the small engine industry.
