Ethanol produced from fermentation of biomass has been of interest as a potential partial replacement for petroleum in SI engines for some time. The oxygenated nature of the ethanol molecule can aid combustion and reduce production of partial combustion products (HC, CO). Ethanol can be splash blended with petrol to produce blends. Blends with up to 10 % ethanol can be used with few problems in all but the oldest vehicles; up to 15 % ethanol has recently been deemed safe for use in light duty vehicles produced with the last decade. The E85 blend (85 % ethanol) requires specially designed vehicles, which are becoming more common in certain markets. The main issues associated with the use of ethanol and its blends are its corrosivity, affinity to water and its lower stoichiometric ratio. Increases in emission of aldehydes and a slight increase in emission of oxides of nitrogen have also been reported, and concern has been raised over the potential of increased aldehyde emissions to form more ground-level ozone. The potential for an improvement in air quality, engine performance and fuel supply security and sustainability makes work on the production and usage of ethanol and its blends a multidisciplinary research priority.
