Investigation of Tribological and Thermophysical Properties of Engine Oil Containing Nano additives

The present study is concerned with resolving issues pertaining to problems involving engine oil and its effective performance. It recommends the usage of a Nano fluid prepared with engine oil as the base fluid, possessing better and enhanced thermo-physical, lubrication properties compared to base engine oil. MWCNTs and Zinc Oxide nanoparticles having volume fraction 0.005%, 0.02%, respectively, were dispersed along with Gum Arabic surfactant in SAE 20W40 engine oil. Tribological properties such as wear resistance, friction coefficient and thermo-physical properties such as thermal conductivity, viscosity, flash point of resulting Nano lubricant were evaluated and were compared with that of plain engine oil.
