Abstract: A method for determining engine oil system health includes determining an oil level in an engine oil sump of an engine, determining an oil consumption rate of the engine based on a current oil volume and a time at which the oil was last replenished, determining a remaining useful oil volume based on the oil consumption rate and duty cycle data of the engine, and generating an alert in response to the oil consumption rate being greater than a predetermined threshold, the alert comprising a command to a controller associated with the engine to cause the engine to perform an action.

Abstract: A crack detection system for a cylinder head associated with an internal combustion engine of a locomotive is disclosed. The crack detection system comprises: a closed-loop coolant system for cooling the cylinder head; a sensor assembly including a pressure sensor, and a speed sensor; and a controller in communication with the sensor assembly. The controller is configured to monitor a coolant pressure feedback and an engine duty cycle of the internal combustion engine. The controller is further configured to communicate an alert signal indicative of an existence of a crack in the cylinder head when: coolant pressure signals are greater than or equal to a first threshold and less than a second threshold; a pressure decay is calculated greater than a third threshold.
