Patent ID: 7278302

Claim:
A method for the testing of exhaust-gas turbochargers ( 10 ) in which a turbine ( 12 ) of the respective exhaust-gas turbocharger ( 10 ) is driven by means of air which is under pressure, and the testing being carried out with the inclusion of measurement quantities on the compressor ( 13 ) of the respective exhaust-gas turbocharger ( 10 ), comprising the steps of: a) generating the pressure of the air which is under pressure at least partially by an internal combustion engine ( 11 ) driven in trailing mode; b) providing a throttle on or downstream of a delivery side of the compressor ( 13 ); and c) using a boost pressure between the delivery side of the compressor ( 13 ) and the throttle as the measurement quantity of the compressor which is to be determined.
