Abstract: Systems and methods for lubricant dilution detection are disclosed. A method for detecting lubricant dilution for a lubrication system includes detecting a low idle condition. The method includes receiving sensed values indicative of lubricant pressure and lubricant temperature during the low idle condition. The method also includes determining a lubricant pressure threshold based on the sensed value indicative of lubricant temperature. The method further includes determining lubricant dilution based on the sensed value indicative of lubricant pressure and the determined lubricant pressure threshold during the low idle condition. In accordance with a determination that there is lubricant dilution, the method includes outputting an indication of the lubricant dilution.

Abstract: Lubricant dilution detection systems and methods are disclosed. A method for detecting lubricant dilution for a lubrication system includes detecting a shutdown event of the lubrication system. The method includes measuring lubricant pressure during the shutdown event. The method further includes determining lubricant dilution based on the measured lubricant pressure during the shutdown event. In accordance with a determination that there is lubricant dilution, the method includes outputting an indication of the lubricant dilution.

Abstract: A system for determining health of a component is provided. The system includes an operational parameter module associated with the component and in communication with a controller. The controller is configured to receive an operating parameter signal from the operational parameter module. The controller is configured to monitor a change of the operating parameter over a predetermined time period. The controller is configured to compare the monitored operating parameter with a first predetermined threshold. The controller is configured to determine a rate of change of the monitored operating parameter over the predetermined time period. The controller is also configured to compare the determined rate of change with a second predetermined threshold. The controller is further configured to determine the health of the component based, at least in part, on the comparisons with the first and second predetermined thresholds respectively and one or more additional parameters associated with the component.
