Abstract | Contributions to the growing environmental concerns by internal combustion engines (ICEs) is the impetus of this research. Therefore, the tribological behavior of lubricants formulated with nano/mineral, nano/bio, and bio/mineral combinations were investigated for the improvements to ICE performance by reducing friction, wear, fuel consumption and exhaust emissions. Mineral-based multigrade engine oil (15W40) was chosen as the reference oil to govern the research. Coconut oil (CCO) was chosen with 15W40 as bio and mineral-base stocks respectively for sample formulations. Graphene (G), Al2O3, TiO2, Al2O3/G, TiO2/G and TiO2/reduced graphene oxide (r-GO) were utilized as nano-additives to blend with both mineral and bio-based formulations. Identity of the selected nanomaterials were confirmed using X-ray powder diffraction (XRD), transmission electron microscopy |
