CONTROL DEVICE FOR TURBOCHARGER

摘要

The present invention relates to a control device (26) for a turbocharger (17) for supplying compressed intake air to an internal combustion engine (1). The control device includes: a storage part (27) configured to pre-store a map (33); a detection part (28) configured to a characteristic parameter; a calculation part (29) configured to obtain an efficiency η of the turbocharger on the basis of the detected characteristic parameter; a determination part (30) configured to determine presence of deterioration of the turbocharger by comparing the detected characteristic parameter and the obtained efficiency η with the map (33); and an informing part (31) configured to inform a user of a maintenance request.

1. A control device for a turbocharger for supplying compressed intake air to an internal combustion engine, comprising:
a storage part configured to pre-store a map which defines a relationship between at least one characteristic parameter and an efficiency of the turbocharger; a detection part configured to detect the at least one characteristic parameter of the turbocharger; a calculation part configured to obtain the efficiency of the turbocharger on the basis of the detected at least one characteristic parameter; a determination part configured to determine presence of deterioration of the turbocharger by comparing the detected at least one characteristic parameter and the obtained efficiency with the map; and an informing part configured to inform a user of a maintenance request if the determination part determines that the deterioration is present.
