Effect of alcoholic and nano-particles additives on tribological properties of diesel–palm–sesame–biodiesel blends
This study focused on evaluating the lubricity of diesel–biodiesel fuel with oxygenated alcoholic and nano-particle additives. Fuel injection system lubrication depended primarily on the fuel used in the diesel engine. Palm–sesame oil blend was used to produce biodiesel using the ultrasound-assist...

| Summary: | This study focused on evaluating the lubricity of diesel–biodiesel fuel with oxygenated alcoholic and
nano-particle additives. Fuel injection system lubrication depended primarily on the fuel used in the
diesel engine. Palm–sesame oil blend was used to produce biodiesel using the ultrasound-assisted
technique. B30 fuel sample as a base fuel was blended with fuel additives in different proportions prior
to tribological behavior analysis. The lubricity of fuel samples measured using HFRR in accordance with
the standard method ASTM D6079. All tested fuels’ Tribological behavior examined through worn steel
balls and plates using scanning electron microscopy (SEM) to assess wear scar diameter and surface
morphology. During the test run, the friction coefficient was measured directly by the HFRR tribometer
system. The results exhibited that B10 (diesel) had a very poor coefficient of friction and wear scar
diameter, among other tested fuels. The addition of oxygenated alcohol (ethanol) as a fuel additive
in the B30 fuel sample decreased the lubricity of fuel and increased the wear and friction coefficient,
among other fuel additives. B30 with DMC showed the least wear scar diameter among all tested fuels.
B30 with nanoparticle TiO2 exhibited the best results with the least wear scar diameter and lowest
friction coefficient among all other fuel samples. B30+DMC demonstrated significant improvement in
engine performance (BTE) and carbon emissions compared to different tested samples. B30+TiO2 also
showed considerable improvement in engine characteristics. |
