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 (II) nitrate (AgNO3),
manganese (II) nitrate hydrate (Mn(NO3)2. xH20) and nickel(II) nitrate
hexahydrate (Ni(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
(BSFC) declined in parallel with the increase in nanoparticle concentration. In
addition, it was shown that the Sound Pressure Level (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.
