What Causes Abnormal Noises from the Supercharger?
2 Answers
The reasons for abnormal noises from the supercharger are: 1. Damage to the turbocharger, causing abnormal noises due to metal friction; 2. Air leaks in the intake or exhaust pipes, or cracks in the intercooler, leading to pressurized gas leakage; 3. Rupture of the bypass valve diaphragm, resulting in gas leakage; 4. Burrs or protrusions on the inner wall of the housing, causing abnormal noises when high-speed airflow passes through; 5. Accumulation of dirt in the diffuser section of the turbocharger; 6. Dirt buildup on the impeller surface, obstructing smooth airflow. A supercharger is an air compressor that increases air intake by compressing air. It utilizes the inertial force of exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then pressurizes the air delivered through the air filter pipe, forcing it into the cylinders.
I've noticed that superchargers making abnormal noises is quite a common issue, mainly caused by bearing wear or insufficient lubrication. My own car had a similar problem before, producing sounds like grinding or squealing, especially more noticeable during acceleration. At that time, I checked the oil level and found it was a bit low. After topping it up, the situation improved. However, if the noise persists, more attention is needed. For instance, foreign objects might be stuck in the turbine blades, or there could be a leak in the exhaust system, both of which can generate noise. Additionally, if the oil pump isn't functioning properly, it can also put a strain on the supercharger. I suggest not pushing the car too hard; instead, stop to check the oil condition and promptly visit a professional shop for inspection. Regular maintenance is crucial, such as changing the oil and air filter every 5,000 kilometers, which can effectively prevent such issues. If the turbocharger fails, it affects the engine's power, and replacing it can be costly. Addressing the problem early saves money and ensures safety.
