Experimental Investigation of AL2O3 Nano Particles Effect on Soot Release and Morphology Emitted from A Diesel Engine
The goal of this study is to evaluate the influence on the concentration of soot generated by gasoline engines at varying load and compression levels by adding Al2O3 nanoparticles to pure diesel oil. Nano-fueled gasoline produced from aluminum oxide (Al2O3) mixed with diesel fuel (particle diameter <50 nm). The study was conducted on a single cylinder, four-stroke, direct-injecting diesel engine with a variable compression ratio of displacement (553 cm3). The engine develops of 3.7 kW at 1500 rpm. Three doses of nano-AL2O3 particles (25, 50 and 100 ppm) are prepared. It is found generally that adding Nano-particles to diesel fuel reduces the emitted soot concentration. However the effect of adding nanoparticles is most significant at a dose of 100 ppm at full load. The results also show that the soot concentration is further reduced by increasing the engine compression ratio for all loads and doses.
