Modification of lubricant properties in a recirculating lubricant system

摘要

A device and a method for real time optimizing engine lubricating oil properties in response to actual engine operating conditions. The present invention is a method that comprises measuring, directly or indirectly, a system parameter of interest near a location of interest, calculating from said parameter(s) or input(s) the amount of a secondary fluid selected from performance enhancer(s), additional base lubricant, alternatively formulated lubricant or diluent that need be added to the base lubricant; and supplementing said base lubricant with said secondary fluid before introducing the combination into said monitored location.
