Abstract

This project will study the behavior of friction and wear on rings and engine cylinders, furthermore the possible influence of lubricating oil contamination with compounds derived from the combustion of ethanol fuel (used oil). In addition, will be studied the effect of incorporation in different concentrations of lipophilic magnetite nanoparticles as an additive in lubricating oil and its possible influence on the coefficient of friction and wear in the ring-cylinder system.
