The increasing industrialization and motorization of the world has led to a steep rise for the demand of petroleum products. Petroleum based fuels are obtained from limited reserves. These finite reserves are highly concentrated in certain regions of the world. Therefore those countries not having these resources are facing a foreign exchange crisis, mainly due to the import of crude oil. Hence, it is necessary to look for alternative fuels, which can be produced from materials available within the country. In addition, the use of vegetable oils as fuel is less pollution than petroleum fuels. In the wake of this situation, there is an urgent need to promote use of alternative fuel which must be technically feasible, economically competitive, environmentally acceptable and readily available. The use of vegetable oils as a fuel in diesel engines causes some problems due to their high viscosity compared with conventional diesel fuel. Dilution, pyrolysis, Micro-emulsification and transesterification are the four techniques applied to solve the problems encountered with the high fuel viscosity .Among these; the transesterification is an important process to produce the cleaner and environmentally safe fuel from vegetable oils. In this thesis work, the transesterification process of castor oil (co) and neem oil (no) in order to obtain bio diesel. Different parameters for the optimization of bio diesel products were investigated in the first phase, and the effects were characterized to test their properties as fuel in diesel engines such as viscosity, density, flash point and fire point. While in the next phase come & Nome was produced by transesterification method using castor oil, neem oil and methaile alcohol, and its effects on reaction temperature, catalyst percentages, and reaction time for optimum bio diesel production have been studied. The blends of various proportions of the come & nome with diesel were prepared, analyzed and compared with diesel fuel, and comparison was made to suggest the better option among the bio diesel understudy. However, its diesel blends showed reasonable efficiencies.
