Abstract: Abstract The rapid diminish of petroleum resources, escalating environmental pollutants, and ever-growing petroleum prices have emerged as a unique focal point on renewable sources like biofuel. The transesterification method was used to acquire soybean methyl ester (SME) from extracted soybean oil. Then, the biodiesel blends on volume bases such as B10 (10% SME with 90% neat diesel), B20 (20% SME with 80% neat diesel), and B30 (30% SME with 70% neat diesel) were prepared. Primarily, experimentation with neat diesel and biodiesel blends on Kirloskar made diesel engines with a standard CR 18. It is found that B20 is shown lower emissions such as HC, CO, and relatively higher brake thermal efficiency (BTE) than the other samples. Further, retarded and advanced the compression ratios (CR) as 17 and 19, respectively. Based on the obtained results observed, the 7.11% enhanced BTE for B20 at CR19 to the neat diesel. B20 at CR19 exhibits the diminution emissions such as CO and HC about 6% and 21% than the B20 at standard CR. At B20 with CR19 showed a drastic reduction in smoke opacity, which is around 38.8% lesser than the diesel fuel operation. The overall observation recommends blend B20 at CR19 to attain the hopeful outcome from compression ignition engines.
