Abstract
In the present study, the engine oil reinforced with multi-walled carbon nanotubes is used to improve the thermal characteristics of the SAE 20W40 engine oil. Multi-walled carbon nanotube (MWCNT) is used as the Nano particle and SAE 20W40 engine oil is chosen as the base fluid. Viscosity, flash point, fire point, pour point and thermal conductivity are the quality parameters effective in analysing the thermal performance of engine oil were also studied. Bath type Ultra sonication method is used for dispersing the Nano particle in the engine oil at two concentrations of 0.2 and 0.4 wt. % respectively. The experimental results reveal that the thermal properties of the engine oil with MWCNTs is enhanced significantly as compared to that of the base oil.
