Engine by reducing friction and wear with proper lubrication. We analysed the tribological behaviour of Nanoparticles as additives in SN500 base oil and compared results with standard base oil. We found the appropriate concentration of Nanoparticles for better tribological properties. Keywords —friction, wear, Nanoparticles, concentration, base-oil. ----------------------------------------************************---------------------------------- I. INTRODUCTION 15% of total input energy in an I.C. engine is lost due to friction of sliding or reciprocating components in contact. This loses can be effectively reduced by using additives like nanoparticles in lubricating oils [1] . Addition of Nano powders in lubricants results in formation of harder and rougher layer of lubrication between two sliding surfaces [2] . The additions of CuO Nanoparticles in the API-SF engine oil & the base oil decreased the friction coefficient by 18.4 and 5.8% respectively, and reduced warn depth by 16.7 and 78.8% respectively as compared to the standard oils without CuO Nano particles [3] . Addition of nickel Nano particles to PAO6 results in a decrease in friction and wear and an increase in the load-carrying capacity of base oil.The friction reduction was between 7% and 30% and wear was decreased between 5% and 45% [4] . CaCO 3 nanoparticles can dramatically improve the load carrying capacity, as well as the anti-wear and friction-reduction properties of PAO base oil [5] . Outcome of review 1. Nano particles used as additives in lubricating oil exhibits good friction reduction and anti- wear behaviour. 2. The anti-wear mechanism is attributed to the deposition of Nanoparticles on the worn surface, which may decrease the shearing stress, thus improving the tribological properties. 3. Lubrication film that form on worm surfaces and Nano particles in the film not only bear the loading, but also separates rubbing faces and avoid direct contact. II. SPECIFICATIONS A.
