Performance of a diesel engine fuelled with rubber seed oil biodiesel

In order to test the applicability of B5 and B20 biodiesel on the diesel engine,an experiment was carried out on a WD61550 diesel engine fuelled with B5 and B20 compared with 0# diesel and-10# military diesel.The engine outer characteristics and load characteristics were tested by determining the power,torque and fuel consumption.The results showed that the engine fuelled with biodiesel or contrast diesel had the same changing trend in outer characteristics and load characteristics parameters.There was nearly no difference in dynamic performance and fuel economy for B5 and 0# diesel,but for B5 it was a little poor than that of-10# military diesel.The engine fuelled with B20 had a bit poor dynamic performance than 0# diesel and-10# military diesel,and fuel consumption had a small increase.As a whole,rubber seed oil biodiesel could be used in existing diesel engines without any modifications.B5 and B20 also could substitute for 0# diesel.
