SYSTEM AND METHOD FOR DIAGNOSING A TURBOCHARGER OF AN INTERNAL COMBUSTION ENGINE BASED ON THE LUBRICATING OIL PRESSURE SIGNAL

摘要

A method includes the steps of receiving a signal indicative of a monitored pressure of a pressurized oil supply of a turbocharger or other turbomachine, determining whether a high frequency component of the signal meets one or more designated criteria, and, if the high frequency component of the pressure meets the one or more designated criteria, generating a first control signal, the first control signal indicating an operator alert relating to a predicted health of the turbocharger.
