In recent times, several developing countries have significantly focused their research on for renewable fuels in order to save the fossil fuel for the future generations. The methyl esters of edible and non-edible oils are predominantly distinguished alternative fuels because of their low emission characteristics and environmental friendliness. Currently the research has been shifted towards animal fat oils and this paper is aimed at evaluating the emission characteristics of fish oil methyl ester (FOME) and their diesel blends as bio-fuel. Methyl Ester of Fish Oil (FOME) was derived through transesterification process and to achieve the intended objective, an experimental investigation was carried-out using single cylinder, 4-stroke water cooled direct injection compressive injection engine fueled with FOME and different blends (BF20, BF40, BF60 and BF100) of FOME in comparison to diesel. The experiment results reveals that BF100 has lower CO emission, lower smoke density, lower particle pollution and relatively higher NOx emission values when compared to Diesel.
