optimal blends

The aim of this study is to evaluate the effect of blending ratios of Jatropha biodiesel with fossil diesel on compression ignition engines. The main goal is to compare the physical and chemical properties of Jatropha biodiesel and fossil diesel and evaluate engine performance,such as power output,torque,and fuel consumption,for different blend ratios and also examine the emissions characteristics (TVOC, CO, PM) that arise from various blend compositions. Physiochemical analysis confirms the suitability of esterified Jatropha oil for industrial applications. Engine performance tests reveal favourable metrics for biodiesel blends, with varying emissions characteristics across blends. Operational assessment indicates blenddependent differences in construction time, emissions, and particulate matter. Cost-benefit analysis shows economic feasibility and environmental benefits of Jatropha biodiesel. The optimal blending ratio considering performance, emissions, and economic factors suggested B30 and B40 blends for specialized applications and B10 for general use.
