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.

Systems and methods for lubricant dilution detection

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.

Lubricant dilution detection system

A failure detection device is disclosed. The failure detection device may receive operations data related to operations of a set of parts of a machine. The failure detection device may process the operations data using a condition-based processing technique. The condition-based processing technique may be associated with mapping initial values of data elements of the operations data to binary values based on satisfaction of a first set of conditions by the initial values. The failure detection device may detect a presence of a possible issue with the operations of the set of parts based on a second set of conditions, associated with the binary values and the initial values, being satisfied during a time period. The failure detection device may perform, after detecting the presence of the possible issue, a set of actions related to addressing the possible issue.

Failure detection device for detecting an issue with a part of a machine

A system for detecting a fault condition in a valvetrain of an engine is configured to measure one or more operating parameters associated with the engine and determine if the operating parameters satisfy pre-defined corresponding boundary conditions. If so, a pair of values of at least one performance parameter is measured corresponding to measurement on a first and second bank of cylinders present on the engine. The difference between the pair of values is determined and used to compute at least one measure of variation for the at least one performance parameter in a time segment. If the at least one measure of variation for the at least one performance parameter exceeds a pre-defined limit for the engine, the valvetrain is flagged as faulty.

System and method for detecting a fault condition associated with a valvetrain of an engine

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.
