Abstract: A method and apparatus for determining the total base number of a used lubricant from an open, all loss, lubricating system. An AC voltage signal is applied between electrodes immersed in the used lubricant and a used-lubricant dependent response to the applied signal measured. The used lubricant base number is determined from the response. To allow for changes in the fresh lubricant inputted to the open lubricating system, the method and apparatus can have means for determining properties of the fresh lubricant needed to determine the total base number of used lubricant. To allow for possible contamination of the used lubricant, the method and apparatus can have means for determining the concentration of contamination and for determining properties of the contaminant needed to determine the total base number of used lubricant.

Abstract: A method for determining a fuel-dilution condition of a lubricant used in transportation and industrial equipment. The method uses apparatus that applies a high frequency and optionally a low frequency oscillating signal to electrodes immersed in the fluid and quantifies fluid response to the signals. Apparatus can further include means to control the lubricant temperature, or a temperature sensor to monitor the lubricant temperature at the electrodes. The method monitors response of the lubricant to the applied electrical signals and determines ratios of lubricant properties. The high-frequency lubricant property ratio or change of high frequency lubricant property as a function of a lubricant use-measure is compared to a predicted ratio based on lubricant use and an estimate of the lubricant's fuel dilution determined. The optional low-frequency lubricant property ratio is compared to thresholds to determine when the lubricant loses the ability to control fuel dilution. The method outputs information relevant to the fuel-dilution condition of the lubricant.
