摘要: Methods and systems are provided for an engine including a crankcase. A condition of the engine may be diagnosed based on frequency content of crankcase pressure. Different types of degradation may be distinguished based on a frequency content of multiple frequencies of the crankcase pressure. Thus, a degraded engine component may be identified in a manner that reduces service induced delay.

摘要: Various methods and systems are provided for a turbocharger. In one example, a method includes determining a first pressure at a first location within a turbocharger and determining a second pressure at a second location within the turbocharger. The method further includes indicating degradation of the turbocharger based on the first pressure and the second pressure.

摘要: Systems and methods for diagnosing or prognosing mobile and/or fixed client assets in a logical and interactive manner. Embodiments of the present invention provide a data analyzer with one or more asset diagnostic models. An asset diagnostic model is configured to logically and systematically interact with a client asset and analyze operational parameter data obtained from the client asset to diagnose a problem with the client asset and/or to predict or forecast future problems or conditions of the client asset.
