Experimental Investigation on the Effect of Nano Fluids on the Performance and Emission Characteristics of a Biodiesel Based Diesel Engine

Diesel engine plays a vital role in the automobile and heavy duty applications due to its reliability a high performance, even though diesel has many advantages it has its own drawback as it is a renewable source will deplete soon. The depletion of fossil fuel must be resolved by finding a better replacement for diesel without affecting the performance of the engine. So we produce lemon grass oil as a biofuel for an alternative source but in viscosity was a problem to used was in diesel engine, so we go for the transesterification process which reduces the viscosity dramatically. Once preparing lemongrass biodiesel add the nanoparticles through sonification process. By adding nanoparticles to the biodiesel to enhance the heat transfer rate. Such a biodiesel can be used in single cylinder direct injection diesel engine with compression ratio 16.5 carry out the performance and emission characteristics.
