Abstract: A health monitoring system for a prime mover of a locomotive is disclosed. The health monitoring system comprises: the prime mover having a cylinder head with a first bank and a second bank; an EGR cooler; a turbocharger; a first temperature sensor provided on a first exhaust and a second temperature sensor provided on a second exhaust; a barometric pressure sensor; a controller in communication with the first temperature sensor, the second temperature sensor, and the barometric pressure sensor, the controller configured to: monitor a temperature relationship between the first temperature sensor and the second temperature sensor in real time at varying altitudes and atmospheres; detect instances of temperature differentials during operation; and identify an operational issue when instances of temperature differentials exceeds a temperature differential limit.
