Abstract: A method for determining quality and condition of a highly resistive fluid in transportation and industrial equipment. The method uses apparatus that applies a multitude of oscillating voltage signals at determined frequencies and offsets to electrodes immersed in the fluid and quantifies fluid response to the signals. The method monitors response of the fluid to a preferred three fixed electrical signals applied by the apparatus, a high and a medium frequency signal with zero offset voltage and a low frequency signal with an offset voltage. For apparatus or applications where the monitored fluid is not controlled to constant temperature, the method includes correcting the temperature sensitive fluid responses for temperature variations for the fluid quality and condition determination. The method can also include determining when essentially complete fluid exchanges are made to the equipment without need for additional input.

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.

Abstract: An apparatus and method for monitoring a highly electrically-resistive fluid. The method includes applying across the fluid an AC signal that includes at least two different AC electrical potentials, with at least one AC electrical potential having a non-zero DC offset, measuring the fluid's electrical response at each applied potential, and analyzing the fluid quality and/or condition using the applied AC signal and the corresponding measured electrical responses. The invention finds application in conjunction with the on-line (i.e., while in use) monitoring a highly resistive fluids such as, e.g., lubricants, natural and/or synthetic motor oils optionally including standard additives and/or adjuncts, combustion engine fuels, other hydrocarbon-based fluids used in transportation and industrial applications, and the like.

Abstract: A lubrication system for supplying a portion of the engine lubricant to one or more gear devices driven thereby and return to the engine independent of whether the gear devices are being driven at the time. Thus even when the engine is idling engine lubricant is circulated through the gear devices to maintain the temperature of the lubricant circulating through the gear devices within a relatively narrow temperature range. Also, the lubricant level within the gear devices will be maintained without the need for inspection of the gear devices as long as the engine lubricant level is regularly checked and maintained either manually or automatically. Further, by changing the engine lubricant at regular service intervals or using an automated lubricant change system, the quality and level of the lubricant in the gear devices is also maintained.

Abstract: The relative motion and force between two interconnected elements can be controlled by a semi-active damper to minimize the instances of the motion exceeding acceptable limits, while maximizing isolation between the elements. Applying an algorithm to the control parameters of the damper provides excellent isolation from input vibration and shocks. The dampers and control algorithms are useful in primary vehicle suspension systems, cab mounts, seat mounts, and engine mounts.

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.
