SYSTEM AND METHOD FOR DETECTING IMPAIRED OPERATION OF AN INTERNAL COMBUSTION ENGINE TURBOCHARGER
摘要
A method and system for detecting impairment of a turbocharger installed as part of an internal combustion engine includes turbo speed monitoring for determining a rotational speed of a turbocharger and airflow sensing for determining airflow rate through the engine. A controller compares the sensed rotational speed of the turbo with a turbo speed threshold and compares the sensed airflow rate with an airflow threshold. A turbocharger impairment flag is set in the event that both the sensed speed of the turbo is less than the turbo speed threshold and the sensed airflow is less than the airflow threshold.
