Biodiesel blends have emerged as a sustainable alternative to fossil fuels. This study investigates the efficiency of various biodiesel blends—specifically B10, B20, B50, and B100—derived from diverse feedstocks such as soybean, jatropha, waste cooking oil, and algae. Unlike prior research which mainly focused on emission data or single-feedstock blends, this paper integrates combustion efficiency, brake thermal efficiency (BTE), and fuel economy in real-world engine conditions. The novelty lies in the methodological synthesis combining experimental rig tests with computational modelling. The results reveal nuanced interplays between blend composition and operational efficiency, offering a more practical roadmap for adoption in transportation sectors.
