The demand for automotive lubricant increasing and consequences in dumping of lubrication oil leads towards the bio lubricants. The present study analyzes rheological properties of Thumba oil to have sustainable lubricant to electric vehicle. The oil samples are tested in plain and with MWCNT and Cerium oxide (CeO2) nanoparticles. It was observed MWCNT and CeO2 made 11% and 9% improvement in viscosity at lower shear rate respectively, however no significant change was observed at higher shear rate. Shear thinning nature of thumba oil biolubricant reduce with the dispersion of nanoparticles and hence contributed in enhancement of lubrication behaviour
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.
Due to the depletion of fossil fuels the prices are increasing sky high and also the pollutants produced from fossil fuels are becoming challenging day by day. Researchers presently focused on bio fuels and bio lubricants to reduce dependence of on fossil.
