“…The TD43F engine test rig uses an electrical dynamometer, which places a load on the engine and the power is dissipated in the resistor network. Therefore, brake power and brake torque are related by (equation 1) (Dimitrov et al, 2021), were simultaneously read from the meters, and shown for all types of fuel (B0, B10, B20, B40) on the (Figure 4). 4a and 4b) shown are the power and torque output of the test engine using different blends of biodiesel (B0, B10, B20, and B40).…”

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