Abstract: This study presents an optimized approach to biodiesel production from rubber seed oil. In this work, an enhanced way for biodiesel production from rubber seed oil was implemented using methyl acetate instead of methanol as the acyl acceptor, which improved the stability of the immobilized lipase. The research further investigates the performance and exhaust emission characteristics of a four-stoke single cylinder CI diesel engine operating on various biodiesel blends. The study examines blends B10, B20, B30 and B40 at compression ratios of 16 and 17.5. The experimental results show that lowest BSFC and maximum efficiency were obtained for B10 blend. Increasing the biodiesel blend percentage reduced the NOx, CO² and CO emissions, although B20 blend showed higher hydrocarbon emissions. Higher compression ratios boosted the engine performance, yielding increased horsepower, improved thermal efficiency and lower fuel consumption. [ABSTRACT FROM AUTHOR]
