ABSTRACT:
The method according to the invention provides for an internal combustion engine (11) driven in trailing mode to generate compressed air for driving the turbine (12) of the exhaust-gas turbocharger (10) to be tested. It is thereby possible to carry out the cold testing of the exhaust-gas turbocharger (10) together with that internal combustion engine (11) with which the exhaust-gas turbocharger (10) is subsequently operated. Furthermore, there is provision, in the method, for throttling the air on the delivery side of the compressor (13). The compressor (13) can thereby be operated under load in the turbine characteristic diagram during the cold test. Thus, further measurement quantities can be determined which make it possible to determine the characteristic of the exhaust-gas turbocharger (10) to be tested in the cold test.
