A system for determining a health of bearing associated with a connecting rod is provided. The system includes an oil collector placed proximate to the connecting rod and configured to receive an oil cast off from side thrust surfaces of the connecting rod during movement of the connecting rod. The system includes a sensor associated with the oil collector and configured to generate a signal indicative of a temperature of the oil cast off from the side thrust surface of the connecting rod. The system also includes a controller communicably coupled to the sensor. The controller is configured to receive the signal indicative of the temperature of the oil cast off from the side thrust surface of the connecting rod. The controller further determines the health of the bearing as a function of the signal of temperature of oil cast off from side thrust surface of the connecting rod.

1. A system for determining a health of a bearing associated with a connecting rod, the system comprising: an oil collector proximate to the connecting rod, the oil collector configured to receive an oil cast off from a side thrust surface of the connecting rod during movement of the connecting rod;a sensor associated with the oil collector, the sensor configured to generate a signal indicative of a temperature of the oil cast off from the side thrust surface of the connecting rod; anda controller communicably coupled to the sensor, the controller configured to: receive the signal indicative of the temperature of the oil cast off from the side thrust surface of the connecting rod; anddetermine the health of the bearing as a function of the signal of the temperature of the oil cast off from the side thrust surface of the connecting rod. 2. The system of claim 1, wherein the controller is configured to compare the temperature of the oil cast off from the side thrust surface of the connecting rod bearing with a predetermined threshold, and determines 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 the oil cast off from the side thrust surface of a plurality of other connecting rods. 4. The system of claim 1, wherein the oil collector includes a plate having a plurality of internal channels provided in an arrangement configured to direct a flow of the oil cast off from the side thrust surface of the connecting rod towards the sensor. 5. The system of claim 4, wherein the plurality of internal channels are provided in a substantially parallel and spaced part arrangement, each of the plurality of internal channels provided in fluid communication with the sensor. 6. The system of claim 4, wherein the plurality of internal channels are provided in a manner wherein the plurality of internal channels converge to form a substantially “V” shaped arrangement in fluid communication with the sensor. 7. The system of claim 1, wherein the oil collector is disposed within an engine housing and proximate to a fork end of the connecting rod. 8. The system of claim 1, wherein the predetermined threshold further includes a pre-calibrated dataset having one or more temperature values. 9. The system of claim 1, wherein the controller is further configured to detect a tendency of failure of the bearing based on the determination. 10. 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. 11. The system of claim 1, wherein the sensor includes a thermocouple. 12. A method for determining a health of a bearing associated with a connecting rod, the method comprising: providing an oil collector proximate to the connecting rod;providing a sensor associated with the oil collector;receiving, by the oil collector, an oil cast off from a side thrust surface of the connecting rod during movement of the connecting rod;generating, by the sensor, a signal indicative of a temperature of the oil cast off from the side thrust surface of the connecting rod;receiving, by a controller, the signal indicative of the temperature of the oil cast off from the side thrust surface of the connecting rod; anddetermining, by the controller, the health of the bearing as a function of the signal of the temperature of the oil cast off from the side thrust surface of the connecting rod. 13. The method of claim 12 further comprising: comparing, by the controller, the temperature of the oil cast off from the side thrust surface of the connecting rod bearing with a predetermined threshold; anddetermining, by the controller, the health of the bearing based on the comparison. 14. The method of claim 13, wherein the predetermined threshold further includes an average temperature of the oil cast off from the side thrust surface of a plurality of other connecting rods. 15. The method of claim 13, wherein the predetermined threshold further includes a pre-calibrated dataset having one or more temperature values. 16. The method of claim 12 further comprising detecting a tendency of failure of the bearing based on the determination. 17. The method of claim 12 further comprising notifying an operator of the determined health of the bearing. 18. 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;an oil collector proximate to the connecting rod, the oil collector configured to receive an oil cast off from a side thrust surface of the connecting rod during movement of the connecting rod;a sensor associated with the oil collector, the sensor configured to generate a signal indicative of a temperature of the oil cast off from the side thrust surface of the connecting rod; anda controller communicably coupled to the sensor, the controller configured to: receive the signal indicative of the temperature of the oil cast off from the side thrust surface of the connecting rod; anddetermine the health of the bearing as a function of the signal of the temperature of the oil cast off from the side thrust surface of the connecting rod. 19. The engine housing of claim 18, wherein the controller is configured to compare the temperature of the oil cast off from the side thrust surface of the connecting rod bearing with a predetermined threshold, and determines the health of the bearing based on the comparison. 20. The engine housing of claim 19, wherein the predetermined threshold further includes an average temperature of the oil cast off from the side thrust surface of a plurality of other connecting rods.
