Performance of Low Heat Rejection Engines with Jatropha Biodiesel

The income of petroleum as fuel is declining day by day and increasing demand of fuels, as well as the gradually more strict system, pose a face to science and technology. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity. The performance of vegetable oils can be improved by modifying them through the transesterification process. Nowadays the performance of single-cylinder low heat rejection single-cylinder diesel engine by using Jatropha biodiesel as fuel was evaluated for its to improving performance and combustion characteristics. Jatropha is mixed with diesel fuel For Jatropha biodiesel and its mixed fuels, the outlet temperature of the engine is increasing with boost in brake power and amount of biodiesel. Calorific value and density were found. A dissimilar range of diesel engine and jatropha biodiesel/diesel ratios of 12/88% (J12), 18/82% (J18), 24/76% (J24), Jatropha 100%(J100) and diesel 100% by value are considered. Results indicated that J24 has a closer performance to diesel has lower brake thermal efficiency, mainly due to its high viscosity compared to diesel.
