Abstract
Alternative internal combustion engines are widely used by all countries in the world, mainly in the transport sector, implying a constant increase in the consumption of fossil fuels, such as diesel and gasoline, among others. There are many searches that look for ways to reduce this consumption without considerable loss of thermal efficiency of the engine. To this end, alternative fuels such as biodiesel, vegetable oil, ethanol and other fuels are currently used. Biofuels mixed with fossil fuels marketed in Brazil has been growing over the years as an alternative to reduce pollutant emissions from combustion, which are quite harmful to human health. The objective of this paper is to analyze the influence of the anhydrous ethanol (EA) in diesel oil addition’s, in concentrations of 5% and 10%. For the tests, a direct injection single-cylinder diesel generator set was used. The diesel oil used in the tests was commercial diesel S10, 8% biodiesel blend with 72% diesel oil (B8) and anhydrous ethanol with 99% purity. The parameters analyzed were power, gas temperature, specific fuel consumption and thermal efficiency of the engine. In order to obtain these results, it was necessary to perform the engine instrumentation, located in the engine laboratory of the Federal University of Pará. Through this study, it is expected to identify the viability of this ternary mixture for diesel engines.
