  • Patent number: 7694553
    Abstract: A calibration flow position of a variable nozzle (6) of a turbocharger is set by a method for calibrating the turbocharger, which comprises a turbine (2) and a compressor (1). In this method, the turbocharger is driven by a predetermined fluid supply. Further, the flow position of the variable nozzle (6) is changed while the rotational speed (N) of the turbocharger or an outlet pressure (P2C) of the compressor (1) is monitored. The calibration flow position is fixed based on the monitored quantities.

  • Publication number: 20070283695
    Abstract: Early detection and avoidance of turbocharger failure are provided by monitoring vibration of the turbocharger rotor using a vibration sensor and providing the output signal of the sensor to a controller programmed to periodically compare the magnitude of the vibration to a predetermined maximum limit. Upon the magnitude of the vibration exceeding the maximum limit, thus indicating a potential abnormal condition, the controller issues a command to a fuel controller for the engine to cause the fuel controller to place the engine in a predetermined safe operating mode selected to reduce the likelihood of turbocharger and engine damage from the abnormal condition.
