Abstract
Various methods and systems are provided for a detecting surge of a turbocharger in an engine system. In one example, system includes a turbocharger including a compressor coupled to a turbine and a controller and sensor system configured to detect a surge event of the turbocharger based on at least one of a rate of change of a pressure measured by sensors downstream of the compressor and a measured rate of change of turbine speed, store operational data associated with the surge event in memory of the controller, and determine a performance of the turbocharger based at least in part on one or more of a cumulative number of detected surge events, a magnitude of detected surge events, or associated operational data.
