ABSTRACT
The enhancement of the
physicochemical characteristics of fossil fuel has been the subject of
extensive research to achieve better efficiency and reduced emissions. Diesel
is one of the fossil fuels that are highly consumed in daily life. This paper
focuses on the behavior of a refined diesel fuel when copper oxide
nanoparticles are added. The resulting blend of nano-diesel has been analyzed
using a four-stroke engine under two loads indicating light vehicles and heavy
duty vehicles. The nano-diesel was prepared by the aid of an ultrasonicator and
a mechanical homogenizer. A base diesel was taken as a reference to distinguish
the effect of the nanoparticles additives. Three different samples with
different concentrations are utilized in this study. As a result, the fuel
consumption, exhaust temperature, brake power, power losses and engine
efficiency have been evaluated and compared to the base diesel in order to
demonstrate and access the enhanced performance of the nano-fuel blend. The
three concentrations conducted were 100 ppm, 200 ppm and 300 ppm of copper oxide nanoparticles. The
results represented that the pure refinery diesel has low exhaust temperatures,
high brake power and high efficiency as compared to the commercial diesel
supplied from a gas station. In addition, 300
ppm copper oxide nano-diesel showed improvement in
engine performances as compared to the other concentrations and pure diesel. In
this context, lowest fuel consumption for both passenger cars and heavy duty
vehicles was achieved, brake power for passenger cars only was improved and
input power showed improvement however, exhaust temperature was the highest as
for this fuel.
