Abstract
A method () includes executing a wear protocol to derive a start-stop (SS) wear, a steady-state operating hours (OH) wear, or a combination thereof, of a test journal bearing system (). The method () further includes observing operations of an engine () via one or more sensors to determine a number of start-stops, steady-state operating hours, or a combination thereof. The method () also includes determining a determined journal bearing system wear () based on applying a physics-based model () of a journal bearing system () and the transfer function to the number of start-stops, the steady-state operating hours, or to the combination thereof. The method () additionally includes executing one or more actionable items () on the engine () based on the determined journal bearing system wear ().
