Emission and Tribological Studies on Nano CuO/Jatropha Methyl Ester/Synthetic Mineral Oil in a Two-Stroke Engine 2019-28-0095

In lieu of the drastic growth of the vehicle population, there is a huge consumption of fossil fuels and mineral oils for mobility. This leads to depletion in fossil fuels and mineral oils which are the by-products of petroleum. These fossil fuels can’t sustain for a long period of time because of its toxicity. In order to reduce the usage of existing mineral oil for lubrication, a source of non-edible oil from Jatropha curcus is processed as jatropha methyl ester (JME). It is holding high viscosity, density and easy blend with base oil. In this current work, the wear resistance of the lubricating oil is enhanced by the addition of nano-copper oxide particle blend with the base oil. The emission performance and tribological behavior have been experimentally tested in 98.2CC two-stroke air cooled engine. The 20% of JME blend with CuO nano particle provides better emission performance and wear characteristics than the other combination of blends.
