Abstract: Now a days Compression ignition (CI) engines show a significant part in industrial, transportation, power generation, construction equipment and marine propulsion sectors. Due to this the fossil fuel utilization is being increased rapidly in day to day life. In this view there is an urgency to search for alternative sources as a substitute to fossil fuels. The alternative fuels are vegetable oils, natural gas, hydrogen etc. The heat content value of these alternate fuels is inferior to diesel fuel. Hence in this work an attempt is made to use black sesame methyl ester as a substitute to diesel. Further the experiments are performed on single cylinder four stroke water cooled direct injection (DI) diesel engine with different injection timings. The injection timings considered are 23°, 25°, 27° & 29° Before Top Dead Centre(BTDC) using Black sesame methyl ester (BSME) as a substitute fuel. The performance characteristics such as Brake Thermal Efficiency (BTE), Mechanical Efficiency and Specific consumption of fuel are analyzed. The emission characteristics viz., Carbon dioxide (CO), Hydrocarbon (HC) and oxides of nitrogen (NOx) are evaluated.
