Abstract

This experimental investigation is devoted to optimize the compression ratio and fuel injection strategies on single cylinder DI diesel engine fueled with FOME biodiesel. The Fish Oil Methyl Ester (FOME) biodiesel with B20D80, B40D60, B60D40, B80D20 blend ratios are used in the experimental testing and its results are compared with pure diesel. Initially the experiments have been conducted at a compression ratio of 17.5:1 at injector opening pressure (IOP) of 240 bar and 260 bar with 3 and 4 holes fuel injectors having 0.20 mm and 0.25 mm orifice diameter respectively. And later the experiments are conducted at a compression ratio of 18.5:1 by considering the same parameters of IOP and fuel injectors. Finally, by comparing the results at compression ratio 17.5:1 and 18.5:1 it is observed that the biodiesel blends have slightly lesser brake thermal efficiency and reduced smoke emissions in contrast to pure diesel. The blend B40D60 gives better results in comparison to all other blends with respect to brake thermal efficiency (BTE) and smoke emissions at 260 bar IOP and compression ratio (CR) 17.5:1 with 4 hole fuel injector having 0.25 mm orifice diameter. Hence this is the optimized blend operating condition for improved brake thermal efficiency of FOME biodiesel with reduced smoke emissions.
