【 摘 要 】

In the current scenario of constant power drops in Brazil and an imminent crisis in the electricity sector, the use of generators and biofuels such as biodiesel has been quite common in rural areas represents an option for diversification of the energy matrix. This study evaluated the use of soybean biodiesel in different concentrations in a diesel engine cycle under different demands of engine loads. Concentrations used were: 5% (B5), 10% (B10), 20% (B20), 50% (B50), 75% (B75) and 100% biodiesel (B100) in a diesel generator with engine of 5 Hp of four-stroke under different operating conditions of the engine, through the demands of electrical loads: 500, 1.000, 1.500, 2.000 W and off connected to the generator. Tests were conducted to quantify the hourly consumption of fuel and gas emissions. The variables suffered significant influence as the electrical charges and fuel mixtures were changed. The use of biodiesel in higher concentrations considerably reduces the emission of majority of pollutant gases and practically nullified the emission of sulfur in concentrations above 65% biodiesel.
