Investigation of a fish oil biodiesel engine performance under the effects of dispersed Nano-particles

In this study, operating parameters of a diesel engine including engine power, torque and specific fuel consumption, with the oil fish biofuel were investigated under the effect of nanoparticles of silver (Ag) and carbon nanotubes (CNT). Biodiesel was produced from fish oil using trans-esterification reaction. Then, the blend was prepared as volume ratio of %20 biodiesel and %80 diesel (B20). According to past research results, the blend of B20 was used due to its optimal parameters than the other blends. Nanoparticles of silver (Ag) and carbon nanotubes (CNT) with concentrations of 30, 60 and 90 ppm were applied for blending with biodiesel fuel to investigate the impact of Nano fuels on performance of the diesel engine under test. Mean comparison of mixed fuels and engine speed using Duncan was analyzed on their main effect and interactions of measured parameters (power, torque, specific fuel consumption). The experiments were carried out on a single-cylinder diesel engine at engine speed levels of 1800, 2100, 2400 and 2700 rpm, under full load conditions. The results showed that increasing concentrations of nanoparticles using Nano fuel and biodiesel fuel (B20) at all engine speeds, power and torque was increased and specific fuel consumption was decreased compared to biodiesel. Power and torque of the engine were increased with fuel of BD+CNT90 at 2400 rpm as %17.29 and %17.08, respectively.
