【発明の名称】ターボ過給機の疲れ寿命モニタ
Document Type and Number:
Japanese Patent JP2002544443
Kind Code:
A
Abstract:
Turbocharger fatigue life monitors comprise at least one sensor that measures an actual operating condition of the turbocharger, e.g., turbine rotational speed or turbine inlet temperature. The device comprises a central processing unit for receiving information from each sensor and processing the information, using programs and predetermined turbocharger information, e.g., turbocharger material and stress data stored in one or more storage device in communication with the central processing unit, to provide an actual probability of turbocharger failure. The central processing unit compares the calculated probability of turbocharger failure to a predetermined specified probability of turbocharger failure stored in a storage device to determine whether turbocharger service is needed. The central processing unit provides a signal that operates an annunciator to indicate recommended or necessary turbocharger service when the actual probability of turbocharger failure exceeds the specified probability of turbocharger failure. The central processing unit and storage devices can be packaged independent of or as part of an existing turbocharged application system, e.g., an engine control module when the turbocharged application is a vehicle.
