of hybrid nanocellulose and copper (II) oxide nanoparticles added to engine oil as a
lubricant for piston ring-cylinder liner application. Kinematic viscosity, viscosity index (VI)
and dynamic viscosity have been performed for measurement of properties at varying
temperatures (ranging from 30° C to 90° C) and different concentrations (ranging from 0.1%
to 0.9% volume concentration). Thermal characteristics have been measured using similar …
