STUDY OF PERFORMANCE AND EMISSION CHARACTERISTICS OF DIESEL- BIODIESEL BLENDS ON VARIABLE COMPRESSION TEST RIG

The scarcity of petroleum products is forcing renewable energy resources to be more attractive. Biodiesel an alternative fuel created through the transesterification vegetable oils and animal fats. most important biodiesel quality parameters are obtained by paying attention making a trade-off between reaction time temperature. presence contaminants in feedstock, such as water free fatty acids, or impurities final products, methanol, glycerine, soap, causes difficulties during this process. This research work has developed processes produce from Jatropha curcas. was extracted all blends were characterized determine physicochemical characteristics test methods ASTM 6571. emission indicate that B20 less than types oil samples. power torque outputs found better next baseline diesel fuel. smell smoke B40 spicy its density very little compared novel finding study increasing blend increases brake power, reduces brake-specific consumption.
