This article presents a literature review about of the use of ethanol as fuel in internal combustion engines spark ignition (ICE-SI). This begins with a brief description of the various forms of production and major global producers of ethanol, to further deepen in the performance, combustion and regulated emissions the ICE-SI operating with different blends of ethanol with conventional gasoline. The results obtained by different authors on performance, combustion and emissions parameters, such as power, torque, brake mean effective pressure, thermal efficiency, heat release rate, efficiency of combustion pressure in the combustion chamber and regulated emissions (NOx, HC, CO, CO₂ and PM), show that ethanol is an excellent fuel to be used in blends with conventional gasoline, especially in higher ratios in volume than 20% by volume (E20); because is produced a better combustion process caused by the increase in the amount of oxygen, thus achieving improvements in performance parameters and emissions in the ICE-SI such as increases in power and thermal efficiency and reduced emissions of CO and THC. However, are generated increases in some polluting emissions such as CO₂ and NOx caused by the excess oxygen in the combustion and increasing the temperature of the exhaust gases the engines.

Keywords : Ethanol; ICE; emissions; performance; combustion.
