Abstract
Among other biofuels, ethanol proves significant qualities that recommend it as an alternative fuel for classic thermal engines, thus offering opportunities of saving conventional petroleum fuels and diminishing the levels of the main exhaust emissions, especially CO, CO and hydrocarbons (HC). Ethanol 2 could be generously obtained by applying technologies that transform biomass into sugar compounds and alcohol. Vegetal species like poplars, with a rapid growing cycle, offer the main source for obtaining wooden biomass, thus permitting ethanol production by industrial methods, such as enzymatic fermentation of the sugar compounds. The resulting product is tested as to the requested properties, for its further utilization as a fuel for Spark Ignition (SI) Engines. Therefore, regarding its octane number, caloric heat, lubrication capacity, etc., bioethanol shows good features to be used as a single fuel or in mixture with gasoline to supply SI Engines.
