Abstract
Internal combustion engines continue facing pressures to improve efficiency and lifespan, necessitating advanced lubricants. Nanoparticles as additives can generate protective tribofilms, reducing friction and wear. This study examined molybdenum disulfide, nanodiamonds, and graphene nanoplatelets in polyalphaolefin (PAO) oil using ball-on-disk tribology (25°C-100°C) paired with a 1.5L diesel engine dynamometer. Results demonstrated 10-40% decreases in coefficient of friction and wear volume loss with nano-formulated lubricants, linked to interfacial films preventing metal contact during run-in. Favorable friction properties directly enhanced engine output metrics including 3-5% lower brake specific fuel consumption and reduced emissions like NOx and particulates. Microscopy analysis revealed nanoparticle-based layers down to 50 nm thickness responsible for lubrication gains. Fundamental connections between tribology screening and system efficiency improvements establish these tailored nano additives as a practical means for advancing internal combustion technology through friction mitigation alongside indirect benefits like longer hardware lifetime. Further inline testing can replicate long-term impacts of contamination, transients, and compatibility for durable real-world solutions. This cross-functional study exemplifies how understanding specific mechanisms allows developing deliberately engineered lubricant systems, driving innovation in sustainable mobility.
