The aim of this study was to evaluate the use of soybeans methyl biodiesel blends and diesel in an ignition compression engine with fuel direct injection. The tests were performed in a dynamometer bench, using the blends B10, B20 and B100 compared to the commercial diesel (B5). The engine performance was analyzed by tractor power take off (PTO) for each fuel. The best results obtained for the power and the specific fuel consumption, respectively, were: B5 (44.62kW; 234.87g kW -1 h -1); B10 (44.73kW; 233.78g kW -1 h -1); B20 (44.40kW; 236.20g kW -1 h -1) and B100 (43.40kW; 263.63g kW -1 h -1). It was concluded that the best results happened on the use of B10 fuel (more power in only 0.2% than fuel B5 and lower specific consumption in only 0.5% than B5). The B100 fuel showed significant differences compared to the other fuels (power lower 2.8% than B5 and more specific consumption in 10.9% than B5).
