| Zusammenfassung: | A method for diagnosing a turbocharger includes disconnecting the compressor outlet conduit so that the engine is naturally aspirated and using the engine to drive the turbine of the turbocharger. The compressor outlet conduit has a restriction to create a backpressure which is measured along with the inlet pressure, barometric pressure and ambient temperature. The flow rate is determined and compared to acceptable parameters from a map data provided by a turbocharger manufacturer to diagnose if the turbocharger is operating within the acceptable parameters. |
