Title:
METHOD FOR PREVENTING THE RUPTURE OF A COMPRESSOR WHEEL AND/OR TURBINE WHEEL OF AN EXHAUST-GAS TURBOCHARGER
Document Type and Number:
WIPO Patent Application WO/2010/077559
Kind Code:
A3
Abstract:
A method for preventing the rupture of a compressor wheel and/or turbine wheel of an exhaust-gas turbocharger of a motor vehicle, having the following method steps: establishing loading limit values (n(G)) for the compressor wheel and/or the turbine wheel in bench tests; determining loading variables (n) for the compressor wheel and/or turbine wheel during the operation of the exhaust-gas turbocharger in the motor vehicle; processing the determined loading variables (n) in order to establish a loading characteristic value (n(i)) which represents real exhaust-gas turbocharger operation; comparing the loading limit value (n(G)) with the loading characteristic value (n(i)); and outputting a warning (W) if the comparison of the loading limit value (n(G)) with the loading characteristic value (n(i)) yields an exceedance of a predefinable safety margin.
