Effect of Fuel Injection Pressure on Performance and Emission Characteristics of Diesel Engine Fueled with Cashew Nut Shell Biodiesel

Thalari Vasantha | M. L. S. Deva Kumar


Abstract: The world-s fossil fuel recreations are depleting speedily due to exponential growth of population and increased usage of technology. According to the literature survey, the production of fossil fuels is decreased day by day. It is necessary to reduce 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 fuel. Diesel fuelled vehicles discharge significant amount of pollutants like CO, UHC, NOx, lead, soot, which are harmful for environment and society. However, to overcome this menace, the bio-fuels are being used as alternative fuels in IC engines. For complete combustion of the fuel in the cylinder the fuel injection parameters are play a major role in engine. The major parameters are mainly fuel nozzle holes, fuel droplet size and fuel injection pressure. These parameters can influence the engine performance and emission characteristics of an I. C. engine. In this experimental study was carried out tests used a blend of cashew nut shell oil and diesel in a single cylinder, 4-stroke water cooled light duty injection diesel engine at different injection pressures 180, 195 and 210 bar. The tests were carried out for pure diesel and blend of 20 % CNSL oil by volume in diesel at constant speed with varied loads. The performance results at 180 to 195 bars of blend very nearer to pure diesel results. The emissions UHC, CO and CO2 are very less at 180 bars compared to pure diesel. The NOx emissions are lesser for blend at 210 bars than pure diesel. The overall performance is good at 180 and 195 bars. But the emissions are decreased when increasing injections pressure.
