KAJIAN EMISI DAN KONSUMSI BAHAN BAKAR DALAM PENGGUNAAN CAMPURAN BAHAN BAKAR BIOSOLAR PADA KENDARAAN PENUMPANG
Energy scarcity form fossil fuel has established Indonesian Government for making some saving step and driving the utilization of energy from biofuel. Research on utilization of biofuel on diesel engine has already done massively all over the world. In this study, research was conducted on the effect of biodiesel on vehicle emission and fuel economy with the purpose to investigate an effect of biodiesel to both of those parameters. Testing was conducted on vehicle with cylinder volume of 2500 cc fuelled with 2 base fuel of diesel fuel 48 and diesel fuel Euro4 standard in which both of base fuel was blended with biofuel in form of FAME and HVO with ratio of 30% (B30). Test method was using United Nations Economic Commission for Europe, yakni UN ECE R83 and R10.
The results showed the addition of 30% FAME and 30% HVO in petrodiesel and diesel fuel 48, was able to reduce CO and HC emissions. While for NOx emissions there has not been a significant change. In particulate emissions, the addition of FAME to both base fuels was able to reduce particulate emissions, but conversely with the addition of HVO, particulate emissions were higher. For fuel consumption, the addition of FAME and HVO to petrodiesel has not been able to save fuel consumption, instead there was a slight increase of 0.1% for FAME and 0.5% HVO. Meanwhile for diesel fuel 48 the addition of FAME is more economical around 5.5%, while the addition of HVO is a little extravagant around 1.8%.%.
