Mechanism To Reduce Friction/Wear of Diesel Engines By Adding Nanoparticles

Abstract

Present study was carried out for knowing how nanotechnology can be employed for improving the performances in tribology. A significant number of investigations have been reported on the effect of nanoparticles as oil additives. The wear and friction tests were carried on four ball oil tester using ZDDP, NiO and MoS2 nanoparticles in 1wt% combination with mineral oil to provides the reduction in friction and wear. Much of the research suggests that even up to 1% concentrations of such particles are instrumental in reducing wear and friction. Nanoparticle additives have proved to be promising for development of Tribological properties of mineral oil. The tribological properties of typical engine oil like SAE15W40 mineral oil added with nanoparticle additives were studied and then experimental analysis was done. Investigations were performed on oil having concentrations of Zinc Dialkyl Dithio Phosphate, Molybdenum Disulfide and Nickel Oxide nanoparticles and their combinations to find that anti wear properties are improved. The evaluation of the tribological behavior pertaining to friction was determined using four ball oil testing machine TR-30L containing combination of above described nanoparticles together in base oil showed the most promising results.
