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.
Claims20
A method for detecting lubricant dilution for a lubrication system, comprising:
- detecting a shutdown event of the lubrication system;
- measuring lubricant pressure during the shutdown event;
- determining lubricant dilution based on the measured lubricant pressure during the shutdown event;
- and
- in accordance with a determination that there is lubricant dilution, outputting an indication of the lubricant dilution.
A lubricant dilution detection system, comprising:
- a lubrication system;
- a sensor for measuring lubricant pressure in the lubrication system;
- and
- a controller configured to:
- detect a shutdown event of the lubrication system;
- measure lubricant pressure during the shutdown event;
- determine lubricant dilution based on the measured lubricant pressure during the shutdown event;
- and
- in accordance with a determination that there is lubricant dilution, output an indication of the lubricant dilution.
A method for detecting lubricant dilution for a lubrication system, comprising:
- detecting a shutdown event of the lubrication system when one or more operating conditions associated with the lubrication system decreases below a shutdown event threshold;
- measuring lubricant pressure during the shutdown event;
- comparing the measured lubricant pressure to a lubricant dilution threshold
- determining whether the measured lubricant pressure is less than the lubricant dilution threshold;
- and
- in accordance with a determination that the measured lubricant pressure is less than the lubricant dilution threshold, determining lubricant dilution;
- and
- in accordance with a determination that there is lubricant dilution, outputting an indication of the lubricant dilution.
