Abstract
A turbocharged device subject to a surge event during operation, the turbocharged device including a turbocharger having a controller and a bearing assembly, a first sensor configured to detect the oil pressure provided to the bearing assembly, a second sensor in operable communication with the turbocharger, where the controller is configured to determine the magnitude of the surge event based at least in part on a signal provided by the second sensor in response to the surge event, and where the controller is configured to determine the wear inflicted on the turbocharger during the surge event based at least in part on the magnitude of the surge event and a signal provided by the first sensor in response to the surge event.
