Causes of Turbocharger Surge in Diesel Generator Sets

When the turbocharger of a diesel generator set operates at a certain speed, the airflow flow rate of its compressor is reduced to a certain extent due to certain factors. The airflow in the compressor will experience strong oscillation, causing blade vibration and surging noise at the inlet of the compressor, resulting in a significant decrease in intake pressure. This phenomenon is called compressor surge. Surging can lead to unstable operation, reduced power, and black smoke from the exhaust, and in severe cases, it can cause damage to the compressor.
