Abstract:

Disclosed herein are methods for detecting a water leak in a locomotive engine cooling system comprising numerous components, each being a potential source of leakage of water. The method typically comprises performing at least one inspection providing an indication of a water leak from an engine cooling system of the locomotive. The step of performing at least one inspection may comprise at least one of several steps including performing a visual inspection to determine if water is leaking from a portion of the cooling system external to the engine; performing a visual inspection of exhaust of the engine to detect an indication of water vapor in the exhaust; performing a visual inspection to detect an indication of water leaking into an intake air manifold of the engine; performing an engine oil analysis to detect water in the engine lubricant; reviewing a fault log history for the locomotive; and checking a level of a cooling system sight glass. The method allows for the isolation of potential sources of the water leak from one another so as to prevent false positive leak identification caused by transient water flow between the potential sources. If an engine cylinder assembly is a component identified as a potential source of the water leak during the water pressurization test, the method enables further testing to confirm leakage at such cylinder assembly, before undertaking the costly and time-consuming process of removing the cylinder assembly from the engine. Cylinder assemblies can be tested for leaks by performing an air leak test disclosed herein.

Abstract:

There is provided a method of selecting a maintenance operation to be performed on a device. An exemplary method comprises determining a health parameter for the device, the health parameter being predictive of a probability of failure of the device based on archival data about a plurality of devices similar to the device. The exemplary method also comprises performing a first maintenance operation on the device if the health parameter indicates that the probability of failure of the device is below a threshold. The exemplary method additionally comprises performing a second maintenance operation on the device if the health parameter indicates that the probability of failure of the device exceeds the threshold.
