Abstract: A system for detecting spark plug failures in an engine is provided. The system may include one or more sensor devices coupled to the engine and configured to measure engine data, a controller in communication with the sensor devices, and an output device. The controller may be configured to determine at least a misfire count, a secondary transformer voltage, and an exhaust port temperature based on the engine data, identify a fault condition based on one or more of the misfire count, the secondary transformer voltage, and the exhaust port temperature, and perform a corrective action responsive to the fault condition. The output device may be configured to generate a notification corresponding to the fault condition.

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 machine may comprise a memory configured to store liner polish information; and an electronic control module. The electronic control module may be configured to: determine a load factor based on an amount of load on the engine; determine an end of injection factor associated with the engine; determine a liner polish rate based on the load factor and the end of injection factor; obtain, from the liner polish information stored in the memory, information identifying a previous amount of damage to the engine; determine an amount of time between a current time and a time when the previous amount of damage was calculated; calculate a current amount of damage to the engine based on the previous amount of liner polish, the amount of time, and the liner polish rate; and take a remedial action based on the current amount of damage.

Abstract: A system for determining a remaining useful life of a cooling component operatively connected to a prime mover. A controller performs a thermal strain analysis that includes determining the power output of the prime mover based upon sensor signals, determining a temperature output of the prime mover based upon the power output, determining a temperature at each of the plurality of analysis locations based upon the temperature output, determining a temperature difference based upon the temperature at each respective one of the plurality of analysis locations, and determining a thermal strain based upon the temperature difference. The controller repeats the thermal strain analysis at time intervals over a period of time, determines an accumulated damage for the cooling component based upon the thermal strain from each thermal strain analysis, and determines a remaining useful life of the cooling component based upon the material characteristics and the accumulated damage.

Abstract: A machine may comprise a piston; a memory; and an electronic control module. The electronic control module may be configured to obtain information identifying a previous amount of wear of the piston pin bore and information identifying a wear limit; determine a base piston pin bore wear rate; calculate an effective piston pin bore wear rate based on the base piston pin bore wear rate; determine an amount of time between a current time and a time when the previous amount of wear of the piston pin bore was calculated; and calculate a current amount of wear of the piston pin bore based on the previous amount of wear, the amount of time, and the effective piston pin bore wear rate. The electronic control module may further be configured to calculate an amount of damage to the piston pin bore based on the current amount of wear and the wear limit.

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.

Abstract: A machine may comprise a piston; a memory; and an electronic control module. The electronic control module may be configured to obtain information identifying a previous amount of wear of the piston ring and information identifying an initial dimension of a coating of the piston ring; determine a piston ring wear rate based on a cylinder pressure associated with the piston; determine an amount of time between a current time and a time when the previous wear of the piston ring was calculated; calculate a current amount of wear of the piston ring based on the previous amount of wear of the piston ring, the amount of time, and the piston ring wear rate; calculate an amount of damage to the piston ring based on the current amount of wear and the initial dimension; and take a remedial action when the amount of damage exceeds a threshold.
