The aim of this paper was to evaluate the use of sunflower biodiesel blends in a CI engine, direct injection. The test procedure was done in a dynamometer bench had been determined the performance of engine through power take-off (PTO) with use of diesel and sunflower biodiesel blends (B5, B10, B20 and B100). The lubricating oil was analyzed before and after period of 96 hours. The results were: D (40,7 kW; 271 g/kW.h); B5 (40,3 kW; 271 g/kW.h); B10 (39,8 kW; 277 g/kW.h); B20 (40,0 kW; 277 g/kW.h) e B100 (39,8 kW; 291 g/kW.h). It was conclude that the use of blends B5, B10, B20 and B100 decreased the power of PTO máx. 2,2% and increased the fuel consumption máx. 7, 3%. The analyze of lubricating oil showed that the viscosity, water content and level of iron were the parameters more affected, although it had been acceptable.
