Elemental Carbon Lubricant Additive to Suppress Cavitation

摘要

A method for quieting noise and vibration from a crankcase of an engine comprises dispersing a first amount of elemental carbon in a second amount of lubricant oil to yield a concentrated elemental-carbon suspension. The method further comprises adding the concentrated elemental-carbon suspension in an amount effective to quiet the noise and vibration to a third amount of lubricant oil in the crankcase.
