  • Method of employing instrumentation to efficiently modify a lubricant's flow rate or properties in an operating all-loss lubricating system
    Patent number: 6779505
    Abstract: A method to employ instrumentation to effectuate variation in lubricant flow rate or properties in response to actual engine conditions. Preferably, the present invention provides a method for the in situ monitoring of the lubricating oil's effectiveness in a two-stroke diesel engine by measuring the used lubricant's Fe content and fuel sulfur content with XRF technology and the used lubricant's BN with an IR measurement device, and for efficiently modifying the lubricant's properties and/or flow rate to the equipment in response to the actual wear or corrosion needs of the machinery or engine.

  • Method for the analysis of lubricant basicity
    Publication number: 20030164451
    Abstract: The present invention relates to a method to directly measure a lubricating oil's Total Base Number (TBN) during engine operations using an infrared (“IR”) sensing device. The method measures either the actual TBN of the oil, or the TBN depletion of the oil. Either value may be determined without comparison to a reference oil. The method comprises determining the IR spectrum for the oil, pre-selecting a certain frequency range, finding the peak within that range, calculating the absorbance of the peak and determining the TBN or TBN depletion from that value.
