Fuel injection pressure is one of the important parameters which affect the performance and emissions in an internal combustion engine. Fuel injection pressure directly effects the atomization of injected fuel which allows for a more complete burn and helps to reduce pollution. The main objective of this work is production of biodiesel from milk scum waste and to investigate the effect of fuel injection pressure on performance and emission characteristics of milk scum biodiesel and its blends. In the present work single cylinder direct injection diesel engine is used to study the performance and emission characteristics at different injection opening pressures of 190 bar, 200 bar and 210 bar. The produced biofuel is blended with diesel (B10, B20, B30, B40, B50 and B100) were tested for fuel properties to use as substitute fuel for diesel engine. The tests were conducted at constant speed and varying loads for different injection opening pressures. The performance parameters evaluated are break thermal efficiency (BTE), brake specific energy consumption (BSEC) and emissions measured are carbon monoxide (CO), hydrocarbon (HC) and oxides of nitrogen (NOx). The results of experimental investigation with biodiesel blends with diesel are compared with that of diesel. From the test results it was found that biodiesel blend B30 at injection opening pressure of 210 bar gives better performance and emission characteristics compared to diesel.
