The current environmental scenario has required changes in fuel nature, in order to minimize the harmful effects caused by sulfur in diesel. However, reductions in sulfur content promote loss of its lubricity and consequently wear in the injection sy

The challenge for nanotechnology application in automotive lubrication is the difficulty in dispersing the nanoparticles in lubricating oils. Some factors have a direct influence on the dispersion of particles, such as size and shape, which are contr
