Abstract—This paper reviews the technical sustainability of biodiesel and its blends with diesel in C.I. engines. Besides exploring historical background of biodiesel production from vegetable oils, it also provides insight of different methodologies evolved for the conversion of vegetable oil in biodiesel. Properties of Jatropha biodiesel have been compared with the properties of petro-diesel; showing a comparable regime for satisfactory performance of a C.I. engine with biodiesel. Biodiesel reportedly has number of technical advantage over petro-diesel especially on safety and environmental considerations. Cold starting, clogging and storage are some serious technological disadvantages associated with biodiesel. Use of B100 (100% biodiesel) requires some modifications in injection timing and fuel pump. Slight increase in NOx emissions has been also reported. Higher maintenance is also reported with the use of biodiesel.
Index Terms—Biodiesel; C.I. engine; NOx emissions
