This article presents a study of the substitution of diesel fuel by ethyl alcohol in direct burning. The investigation is concentrated in the physical-chemical properties of the fuels, the combustion thermodynamics, the atomization, and the pollutants formation. Results show that hydrated ethyl alcohol can be an attractive alternative for diesel fuel, mainly by the benefits in the combustion process and the pollutants formation. Nevertheless, care must be taken in the substitution to prevent losses by evaporation, fire risks and material damage by corrosion.
