Computer Integrated Manufacturing Systems 196 Influence of Metal Based Nano Fuels on the Engine Performance and Emissions

Abstract

In the ongoing experiment, the emissions and performance specifications of the 4-stroke water cooled diesel engine using biodiesel pongamia pinnata with and without graphene additives are assessed. The use of nanoparticles may be beneficial for biodiesel in engine operation. Nanoparticle suspension in biodiesel can be successfully achieved using solvents that provide a strong bond between biodiesel and nanoparticles to overcome differences in density. Surfactants can be used when mixing liquid with nanoparticles to prevent the sinking or floating of nanoparticles in biodiesel. The use of nanoparticles increases the combustion mechanism due to its rapid combustion and thus decreases emissions as well. The tests for emission levels and performance were carried out at 1500 revolutions per minute constant engine speed. The results of experimentation shows that the addition of graphene to the blends of biodiesel, the curve of brake thermal efficiency (BTE) shifted on the higher side and almost very close to the diesel. The improvement in BTE is found to be 1 to 1.5%.
