Performance Investigation on Diesel Engine Powered by Ternary Blends of Linseed and Calophyllum Inophyllum Methyl Esters

Abstract

The current research is focused on combining two different biodiesels made from different sources. The goal is to take advantage of the benefits of both biodiesels. The problem being addressed is that biodiesels have lower performance and higher emissions compared to regular diesel. The study looks at using a blend of diesel fuel, Linseed oil methyl ester (LOME), and Calophyllum inophyllum methyl esters (CIME) in a single-cylinder diesel engine to evaluate performance and emissions. The biodiesels were made using a trans-esterification process from prestained oil. The blends were labeled B0, B5, B10, B15, and B20. B5 demonstrated the best performance with increased Brake Thermal Efficiency (BTE) and reduced Brake Specific Fuel Consumption (BSFC). The B5 blend had a maximum increase in BTE of 3.92% compared to diesel fuel, and a decrease in BSFC of 10% compared to diesel (B0). The LOME/CIME blend lowered NOx emissions by 6.15% with B5 blend at full load conditions. This suggests that the use of ternary blends such as calophyllum inoplyllum biodiesel and linseed biodiesel can combine the advantages of different feedstocks and be a good alternative fuel option for high-compression engines.
