Abstract
A method of monitoring a turbocharger system makes use of vibrational behaviour to predict potential future failure modes. Changes in sub-synchronous vibrational behaviour of the turbocharger assembly may be used to distinguish between failure modes such as wear and coking. Rate of change of sub-synchronous vibrational behaviour may be used to predict time before likely failure. Also disclosed is a turbocharger system configured to perform the method.
