Enhancement of Thermophysical Properties of SAE20W40 Using Low Concentration Nanoparticles

Engine oils are the lifeblood of any internal combustion engine, playing a crucial role in lubricating, cooling, and protecting its moving parts. They come in various formulations and viscosities, tailored to meet the specific needs of different engines. From enhancing performance to ensuring longevity, understanding engine oil types, properties, and functions is essential for maintaining a healthy and efficient engine. Given the high-strength properties of graphene-based nanoparticles, this study compares and analyzes the thermophysical performance of the commonly used SAE20W40 oil in automobile engines with Reduced Graphene Oxide (RGO) and Carboxyl Graphene (CG) mono and hybrid nanoparticles of 0.001% and 0.005%, respectively. This study aims to enhance the thermophysical properties of the SAE 20W40 oil and improve engine performance and the oil's life span.
