This thesis investigates the tribological viability of bio-based base stock to which different nanoparticles were incorporated for engine piston-ring–cylinder-liner interaction. It determines experimentally the effects of lubricating oil conditions (new and engine-aged) on the friction and wear of the materials used for piston rings and cylinder liners. The specific base stock examined was a trimethylolpropane (TMP) ester derived from palm oil...

The book focuses the rough piston skirts and liner surfaces and to incorporate these aspects in two dimensional hydrodynamic and elastohydrodynamic lubrication (EHL) of piston skirts in the initial engine start-up. This research work considers the deterministic roughness asperity with the average flow factor method.The randomly generated surface with deterministic asperity is modelled for piston skirt EHL. For this developed model, parametric ...
