Oil can be especially electrostatically charged if: It is formulated with a base oil from Group II or III. With increase in the concentration of nanoadditives, some of the properties of engine oil improved, but it must be noticed that an increase in concentration causes a reduction in lubricating properties of engine oil due to agglomeration and precipitation of nanoparticles and as a result causes damage to frictional surfaces. © 2020 Springer Nature Switzerland AG.

The results related to measuring the thermal conductivity coefficient of the base lubricant and the lubricant which contains CuO nanoparticles are shown in Figure 3. 0000003156 00000 n It also provides market trends with respect to drivers, restraints and opportunities. Thermal conductivity and thermal diffusivity of combustion chamber deposits in an s. i. engine and a diesel engine were determined by measuring thickness, response time to a radiation pulse, time-varying deposit surface temperature and deposit-wall interface temperature. After cooling to room temperature, the precipitate is centrifuged, washed twice with triply distilled water, ethanol, and acetone, and finally dried at room temperature.
