This study aims to find the optimum performance and emission characteristics of single cylinder variable compression ratio (VCR) engine with different blends of Annona methyl ester (AME) as fuel. The performance parameters such as specific fuel consumption (SFC), brake thermal efficiency (BTE), and emission levels of HC, CO, Smoke, and NO x were compared with the diesel fuel. It is found that, at compression ratio of 17: 1 for A20 blended fuel (20% AME + 80% Diesel) shows better performance and lower emission level which is very close to neat diesel fuel. The engine was operated with different values of compression ratio (15, 16, and 17) to find out best possible combination for operating engine with blends of AME. It is also found that the increase of compression ratio increases the BTE and reduces SFC and has lower emission without any engine in design modifications.
