Azolla oil is first extracted, and then it is transesterified to produce Azolla methyl ester oil. The ASTM criteria for biodiesel are contrasted with the physical characteristics of esterified oil. Blends of AME10, AME20, and AME30 for diesel fuel are made based on the oil yield rate. To assess the performance, emission characteristics, and combustion characteristics of these blends under various load scenarios, they are tested in a typical diesel engine. According to the results, the AME10 blend behaved more closely regarding performance characteristics than the pure diesel fuel. Comparing AME10 to diesel fuel, however, AME10 demonstrated a notable decrease in emission metrics, including Nox(920 PPM) and HC (52 PPM). It is therefore determined from the experimental evaluation that, with minimal adjustment, the AME10 blend may be a viable fuel source for diesel engines.
