Synopsis:

  

The main objective of this study was to experimentally investigate the use of soyabean oil methyl ester and its blends in a single cylinder direct injection compression ignition engine. The fatty acid methyl esters in soyabean methyl ester were found to be Myristic acid, Palmitic acid and Stearic acid in prominent proportions. The blending ratios of 5%, 10%, 15% and 20% of SOME with diesel were used in this study with varying loads. The combustion study such as in-cylinder, maximum peak pressure, rate of heat release and ignition delay were analyzed and found that SOME 20% blend exhibits maximum cylinder pressure and better heat release characteristics. The effect of injection timing was analyzed by advancing and retarding the injection timing by 5oCAD and found to have positive effect on combustion efficiency with advancement of injection timing.
