摘要：
In this work, the combustion and emission characteristics were studied in a 186FA diesel engine fuelled with biodiesel-diesel to examine the effect of the percentage of biodiesel in the blends, and the experimental investigation was conducted with various blending ratios of biodiesel under different operating conditions. In addition, the combustion noise of the diesel engine fuelled with biodiesel-diesel was analysed, and then the emission characteristics of NOx and soot were studied through simulation analysis where the formation rate and distribution of NOx and soot for pure diesel and B20 fuel were described. Based on the simulation data of the original diesel engine fuelled with B20 fuel, the swirl ratio and fuel injection timing were optimised and the technical measures were suggested to reduce the two different emissions simultaneously. The simulation results showed the emission characteristics were optimal when the swirl ratio was 2.7 and fuel injection timing was 7.5 degrees degree of crank angle before top dead centre respectively.
