Rheological Analysis on Joannesia Princeps Oil for Sustainable Bio-lubricant in Electric Vehicle Application

Abstract

The Petroleum-based lubricants cause harmful effects on the environment due to its non-degradable and highly toxic properties. The shortage of mineral oil reserves leads to finding an alternative for petroleum and its product. The present study analyzes rheological properties of Joannesia Princeps oil for evaluate its potential to work as electric vehicle lubricant. Test samples prepared with multi wall carbon nanotubes (MWCNT) and Cerium oxide (CeO2) nanoparticles to change the enhancement in rheological properties. It was observed that MWCNT and CeO2 made 14% and 12% improvement in viscosity at lower shear rate respectively, however no significant change was observed at higher shear rate.
