Abstract :In current study, exhaust emission, vibration and noise features of diesel engine with addition of metallic based nanoparticles into diesel fuels were investigated experimentally. Various nanoparticles called as silver insert ignore into journalissuearticles values(II); nitrate insert ignore into journalissuearticles values(AgNO3);, manganese insert ignore into journalissuearticles values(II); nitrate hydrate insert ignore into journalissuearticles values(Mninsert ignore into journalissuearticles values(NO3);2. xH20); and nickelinsert ignore into journalissuearticles values(II); nitrate hexahydrate insert ignore into journalissuearticles values(Niinsert ignore into journalissuearticles values(NO3);2.6H2O); were used as an additive to diesel fuel at 25 ppm and 50 ppm dosing level so as to obtain six different fuel samples. Diesel engine with air-cooled and a single cylinder were utilized for engine tests altering engine speed from 1200 to 2800 rpm at the intervals of 400 rpm. The results demonstrated that of the nanoparticle addition did not remarkably affect the physicochemical features of the diesel test blends. But, the addition of nanoparticles slightly raised viscosity, cetane number and the heating value of test fuels especially, at the higher nanoparticle concentrations. In all experiments, with nanoparticle added blend fuels, CO, HC, NOx emission values and brake specific fuel consumption insert ignore into journalissuearticles values(BSFC); declined in parallel with the increase in nanoparticle concentration. In addition, it was shown that the Sound Pressure Level insert ignore into journalissuearticles values(SPL); and vibration characteristics of the engine block also decreased with increasing nanoparticle concentration of test fuels. As a result, AgNO3 addition to diesel fuel has an effective role in both reducing emission and vibration values and reducing BSFC values.
