Abstract: As part of research on alternate fuels, to avoid losing precious agricultural land to plant-based renewable fuel oils, fish oil from discarded parts of Fish has been used.To keep the combustion chamber hot enough to burn the viscous Fish Oil, low heat rejection engine has been fabricated and used. Experiments were conducted on a conventional Single Cylinder Diesel Engine too. The results clearly establish that Fish Oil can indeed be a good Bio-Diesel, without any major engine modifications, and a 20% Fish Oil-Diesel Blend on LHR Engine improves its performance by a good 16%, with better emission characteristics.
