奈米添加劑於生質柴油乳化燃料之應用性

The purpose of this study is to research and produce a high performance emulsion fuel for biodiesel containing nanoadditives, which can be used on the existent diesel engines for performance improvement. In this work, research will be held on direct synthesis method to produce Al2O3/water nanofluid. According to the previous study, Al2O3 has the better performance of suspension, so it has fewer problems for Al2O3 to be used in nanofluids. This Al2O3/water nanofluid will be mixed with commercial biodiesl for the solutions of optimum proportions, which are used as nanoadditives emulsion fuel for diesel engine vehicle. Next, the fundamental physicochemical properties of the emulsions, including calorific value, density, kinematic viscosity and lubricity will be measured, analyzed and evaluated for the performance of nanoadditive biodiesel emulsion fuel property. The present work attempts to study the effect factors of stability of emulsion fuel by investigating the influence of adding Al2O3 nanoparticles to biodiesel, ad in order to confirm the emulsionfication performance and practicability. In the other work, the investigations are carried out to study the performance, emission, and combustion characteristics of a single cylinder diesel engine using biodiesel, water–biodiesel emulsion fuel, and the alumina nanofluid blended biodiesel emulsion fuels. The operating characteristics of diesel engines with dynamometer performance testing will be measured, which in including bsfc, bmep and emissions(NOx and smoke) will be measured, analyzed and evaluated for the performance of nanoadditive biodiesel emulsion fuels for diesel engine application.
