Turbocharger surge is an unstable airflow phenomenon that occurs in the compressor section. It is usually caused by insufficient intake airflow. When the rotational speed of the compressor wheel does not match the intake air flow, the airflow will be separated on the surface of the blades, causing periodic pressure fluctuations. These pressure fluctuations not only affect the compressor but also have the influence to the turbocharger. If the problem is not dealt in time,long-term vibration may lead to the damage of turbo parts, and even cause the turbocharger to be scrapped.
How can we determine if turbocharger surge in our daily lives?
Abnormal sounds.
During surging, the intake end of the compressor will produce an abnormal sound similar to a “puffing” noise. It generates a periodic sound. At the same time, when the airflow fluctuates intensely, a sharp whistling sound may also accompany it. This is especially noticeable when the accelerator is released immediately after a sudden acceleration.
Abnormal power output.
When the vehicle is accelerating, you may feel that the power output is unstable, with a jerky sensation, or even feeling engine shaking. Or when you step on the accelerator, the vehicle speed may not increase but decrease instead, and black smoke may come out of the exhaust pipe. This is because surging causes fluctuations in intake pressure, affecting the combustion efficiency of the engine.
Abnormal instrument parameters.
If your vehicle is equipped with a boost gauge, under normal conditions, the gauge data will rise steadily. When surging occurs, we may observe that the pointer rapidly and frequently swings within the range of 0.1-0.3 bar when accelerating, while the pressure is normal at idle.
Vehicle vibration.
During surging, if you touch the intake pipe with your hand, you will feel obvious high-frequency vibration. Severe surging can cause significant vehicle vibration, especially at low speeds.
Once these phenomena are detected, please contact professional personnel promptly to inspect or replace the turbocharger and its related components to prevent more serious mechanical failures caused by the continuous occurrence of surging.
