A system for determining a health of a bearing associated with a connecting rod is provided. The system includes a sensor associated with the connecting rod and remotely disposed relative to the bearing of the connecting rod. The sensor is configured to generate a signal indicative of a temperature of the bearing. The system includes a controller communicably coupled to the sensor. The controller is configured to receive the signal indicative of the temperature of the bearing. The controller further determines a health of the bearing as a function of the signal of the temperature of the bearing.

1. A system for determining a health of a bearing associated with a connecting rod, the system comprising: a sensor associated with the connecting rod, the sensor affixed on an engine housing and remotely disposed relative to the bearing of the connecting rod, wherein the sensor is configured to generate a signal indicative of a temperature of the bearing; anda controller communicably coupled to the sensor, the controller configured to; receive the signal indicative of the temperature of the bearing; anddetermine the health of the bearing as a function of the signal of the temperature of the bearing. 2. The system of claim 1, wherein the controller is configured to compare the temperature of the bearing with a predetermined threshold, and determine the health of the bearing based on the comparison. 3. The system of claim 2, wherein the predetermined threshold further includes an average temperature of a plurality of other connecting rods. 4. The system of claim 2, wherein the predetermined threshold further includes a pre-calibrated dataset having one or more temperature values. 5. The system of claim 1, wherein the controller is further configured to detect a tendency of failure of the bearing based on the determination. 6. The system of claim 5, wherein the controller is further configured to shutdown a fuel supply to a cylinder based on the detection. 7. The system of claim 1 further comprising a display device communicably coupled to the controller, the display device configured to notify an operator of the determined health of the bearing. 8. The system of claim 1, wherein the sensor includes an infrared sensor. 9. The system of claim 1, wherein the sensor is disposed proximate to a fork end of the connecting rod. 10. A method for determining a health of a bearing associated with a connecting rod, the method comprising: providing a sensor associated with the connecting rod, the sensor affixed on an, engine housing and remotely disposed relative to the bearing of the connecting rod;generating, by the sensor, a signal indicative of a temperature of the bearing;receiving, by a controller, the signal indicative of the temperature of the bearing; anddetermining, by the controller, the health of the bearing as a function of the signal indicative of the temperature of the bearing. 11. The method of claim 10 further comprising: comparing, by the controller, the temperature of the bearing with a predetermined threshold; anddetermining, by the controller, the health of the bearing based on the comparison. 12. The method of claim 11, wherein the predetermined threshold further includes an average temperature of a plurality of other connecting rods. 13. The method of claim 11, wherein the predetermined threshold further includes a pre-calibrated dataset having one or more temperature values. 14. The method of claim 10 further comprising detecting a tendency of failure of the bearing based on the determination. 15. The method of claim 10 further comprising notifying an operator of the determined health of the bearing. 16. An engine housing comprising: a cylinder head;an engine block having a cylinder;a connecting rod associated with the cylinder, the connecting rod having a bearing;a sensor associated with the connecting rod, the sensor affixed on the engine housing and remotely disposed relative to the bearing of the connecting rod, wherein the sensor is configured to generate a signal indicative of a temperature of the bearing; anda controller communicably coupled to the sensor, the controller configured to: receive the signal indicative of the temperature of the bearing; anddetermine the health of the bearing as a function of the signal of the temperature of the bearing. 17. The engine housing of claim 16, wherein the controller is configured to compare the temperature of the bearing with a predetermined threshold, and determine the health of the bearing based on the comparison. 18. The engine housing of claim 17, wherein the predetermined threshold further includes an average temperature of a plurality of other connecting rods. 19. The engine housing of claim 17, wherein the predetermined threshold further includes a pre-calibrated dataset having one or more temperature values. 20. The engine housing of claim 16, wherein the controller is further configured to detect a tendency of failure of the bearing based on the determination.
