ABSTRACT:
A method of avoiding low cycle fatigue failure of a turbocharger for an internal combustion engine having an electronic control module comprising the steps of: counting the number of cycles the speed of the engine and the fuel rate exceed a predetermined combination for a period of time and then drop below a lower predetermined combination for a period of time, determining an allowable number of said speed cycles that the turbocharger can experience without low cycle fatigue failure, comparing the counted number of speed cycles to the allowed number of speed cycles, providing an indication of the percentage of the counted speed cycles compared to the allowable number of speed cycles, and providing a signal that will alert an operator that the turbocharger is approaching low cycle fatigue failure.
