Abstract
A method for estimating damage of a component of an internal combustion engine includes receiving a fuel rate signal indicative of a fuel rate of the internal combustion engine and estimating a temperature value of the component of the internal combustion engine based on at least the received fuel rate signal. The method also includes estimating an incremental amount of damage of the component of the internal combustion engine based on the estimated temperature value of the component of the internal combustion engine, updating a cumulative amount of damage of the component of the internal combustion engine based on the estimated incremental amount of damage, and outputting a notification based on at least the cumulative amount of damage of the component of the internal combustion engine.
