INVESTIGATION ON THE EFFECT OF TiO2 NANOPARTICLE ADDITIVES ON THE PROPERTIES OF 10W-40 ENGINE OIL

The aim of this study is to investigate the influence of TiO2 nanoparticles additives on thermo-physical and tribological properties of 10w-40 engine oil for improvising the life span of the engine and enhancing the performance. Developing a nanofluid is an innovative new class of fluid which was engineered by dispersing 0.01% of TiO2 nanoparticles in conventional 10W-40 engine oil to improve load carrying capacity, anti-wear and friction reduction properties. Conventional Sol-gel method was employed to synthesize TiO2Nanoparticles and was characterized using XRD, SEM and TEM. The average crystalline size was found to be 6nm and existed in anatase crystalline phase. The thermo-physical and rheological tests concluded that TiO2 dispersed engine oil was superior in all aspects than compared to the ordinary engine oil and proved as an alternate substitute for increasing the life span of the engine.
