Experimental studies on the influence of copper oxide nanoparticle on biodiesel-diesel fuel blend in CI engine

ABSTRACT

An experimental research is performed to determine the performance, combustion and emission qualities of a variable compression engine at constant speed using copper oxide nanoparticles as being fuel-borne additives in diesel–biodiesel blend. In this research, the effects of adding CuO₂ nanoparticles to neochloris oleoabundans methyl ester-diesel blended (B20) fuel on compression-ignition engine had been experimentally investigated. The B20 with 25, 50, 75, and 100 ppm dosage of CuO₂ nanoparticles were examined at various engine loads and constant engine speed. The fuel blends were labeled as B20, B20 + 25 ppm, B20 + 50 ppm, B20 + 75 ppm, and B20 + 100 ppm. Moreover, without any engine alterations, the performance, combustion, and emission properties of those fuel blend samples were investigated through the experimentally measured standards such as viscosity, density, cloud point, calorific value, and pour point while the engine performance were examined through the factors such as EGT, BSFC, BTE, exhaust emission of HC, CO, NOx, and smoke opacity. The experimental outcomes show that the use of biodiesel blend along with CuO₂ nano particles in diesel-fueled engine revealed better combustion, good improvement in performance characteristic and also decreased in exhaust emissions.
