Abstract

Abstract

In order to optimize the application of biodiesel for diesel engine, the emissions, fuel economies and power performances of biodiesels with different blend ratios were compared and analyzed by bench tests of a supercharged direct injection(DI)diesel engine, the exhaust emissions of smoke, NOx, CO and HC, effective energy consumption rate and power were investigated under different engine loads and speeds.Experiment result shows that compared with diesel fuel, B10, B20, B30, B50, B80 and B100 blends have, on average, a reduction of 34.69% for smoke emission, an increase of 25.01% for NOx emission, a reduction of 33.05% for HC emission, an increase of 11.13% for CO emission at full load, a reduction of 2.18% for effective energy consumption rate although effective fuel consumption rate is increased, an increase of 5.34% for power, the decreased percentages for smoke emission are 7.01%, 15.37%, 14.17%, 10.45%, 6.73% and 4.39% higher than the increased percentages for NOx emission respectively, so the blend ratio of B20 is optimum.
