The world’s fossil fuel reserves are depleting at higher pace due to exponential growth of population and increased usage of technology. As per the studies there is a gap between demand and supply. This may further increase in coming days of future. It is necessary to fill up the gap between supply and demand. Developing countries like India, invests heavily on imports of petroleum fuels. In such countries most of automotive and transport vehicles are run on diesel. Diesel fueled vehicles discharges considerable amount of pollutants like CO, UHC, NOx, lead, soot, which are very harmful for environment and society. However, to overcome this menace, the bio-fuels are being used in IC engines as alternate fuels. To attain the complete combustion of the charge in the cylinder the fuel injection parameters play a wide role. The major parameters are no. of fuel nozzle holes, fuel droplet size and fuel injection pressure. These parameters can influence the performance of engine as well as emission characteristics of an I.C. engine. In this present work, experimental study was carried out using a blend of Algal oil and diesel in a single cylinder, 4-stroke water cooled light duty injection CI engine at various injection pressures 180, 190 and 200 bars. Here the tests were carried out for pure diesel and blend of 20 % Algae oil by volume in diesel engine at constant speed with varied loads. The performance results at 180 to 190 bars of blend very closer to pure diesel results. The emissions UHC, CO and CO2 are very less at 180 bars than pure diesel. The NOx emissions are lesser at 200 bars compare to pure diesel. The overall performance is good at 180 and 190 bars. But the emissions are decreased when increasing injections pressure
