摘要：Due to limited resources of fossil fuels and the environmental concern, there has been improved focus on vegetable oils and biodiesel fuel as an alternative source of energy. Governments across the world are injecting huge amount of money into the development of this sector in an attempt to reduce their dependency on fossil fuels. However, the alternative diesel fuels must be technically and environmentally acceptable, and economically competitive. From the viewpoint of these requirements, triglycerides and their derivatives may be considered as viable alternatives for diesel fuels. One of the main problems of vegetable oil use in diesel engine is their higher kinematic viscosity due to which problems occur in pumping and atomization, ring-sticking, carbon deposits on the piston, cylinder head, ring grooves, etc. Hence, straight vegetable oils have to be modified to bring their combustion related properties closer to diesel. This fuel modification is mainly aimed at reducing the viscosity in order to get rid of flow/ atomization related problems. In the present work, efforts have been made to understand and compile the outcome of researches on economics of biodiesel fuel, issues associated with use of vegetable oil in diesel engine by using some well known techniques available to overcome higher viscosity related problems for making them compatible with the hydrocarbon-based diesel and biodiesel fuel properties.
