摘要： Various methods and systems are provided for a turbocharger. In one example, a method includes receiving a signal indicative of a monitored pressure of a pressurized oil supply of a turbocharger or other turbomachine. The method further includes 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.

摘要： Methods and systems are provided for an engine. A condition of the engine may be diagnosed based on information provided by signals from a generator operationally connected to the engine and/or other signals associated with the engine. Different types of degradation may be distinguished based on discerning characteristics within the information. Thus, a degraded engine component may be identified in a manner that reduces service induced delay.
