In this experimental study, usage of CuNO3 nanoparticles as diesel fuel additives were studied in order to improve the fuel properties and to
decrease pollution emissions. The nano particles were added into blend of 10% i-propanol and 90% diesel fuel (P10) at the rate of 50 ppm and
100 ppm for preparing test fuels. The test fuels were called as dose ratio of nano particles and symbol of nano particle metal such as‘‘P10Cu50”.
An ultrasonic shaker was used in order to obtain a uniform suspension of the nano particles in P10 fuel. Exhaust emission tests with a four
single cylinder direct injection diesel engine were performed at full load conditions. Viscosity, density, Cetane number, copper strip corrosion
and heating values of the test fuels were determined. Addition of the nano particles improved Cetane number values of P10. However, the other
fuel properties did not change significantly. During the tests, better emission results were obtained with P10Cu100. Smoke opacity, CO and
HC emissions decreased by 23.54%, by 31.03% and by 42.85%, respectively. In general, higher NO emissions with addition of nano particles
were observed at higher engine speeds.
