There are two main types of abnormal noise in turbochargers, one is low-frequency abnormal noise, and the other is high-frequency abnormal noise.

Low frequency abnormal noise refers to low-frequency sounds such as buzzing or whistling that occur after the turbocharger is started. The main cause of this abnormal noise is problems such as damage to the turbine bearings or wear of the turbine impeller bearings. If not handled in a timely manner, it can lead to a decrease in turbocharger performance and affect vehicle driving safety.

High frequency abnormal noise refers to a sharp sound that occurs after the turbocharger is started, usually caused by loose or damaged turbine impeller blades, lack of oil or damage to turbine bearings, and other reasons. This abnormal noise not only affects the driving stability of the vehicle, but may also cause damage to the turbocharger.

The main reasons for the abnormal noise of turbochargers are as follows: firstly, the long-term high load operation of turbochargers leads to component wear and aging; The second is the use of inferior engine oil or prolonged failure to replace the engine oil, resulting in poor lubrication; The third reason is that the driver drives improperly and frequently accelerates or brakes sharply.

In order to avoid the occurrence of abnormal noise from turbochargers, car owners should regularly change the oil, maintain smooth driving, and also pay attention to the maintenance and repair of turbochargers. When facing the issue of abnormal noise from the turbocharger, car owners should promptly go to a professional car repair shop for inspection and repair to ensure the safety of the vehicle and the normal operation of the turbocharger.
