A turbocharger is actually an air compressor that compresses air to increase the amount of intake air. It uses the inertial impulse of exhaust gas discharged from the engine to propel the turbine inside the turbine chamber, which in turn drives a coaxial impeller that compresses the air sent by the air filter pipe and pressurizes it into the cylinder to increase the engine's output power.

Principle of turbocharger:

The turbocharger uses the inertial impulse of exhaust gas discharged from the engine to propel the turbine inside the turbine chamber, which in turn drives a coaxial impeller that pressurizes the air sent by the air filter pipe into the cylinder.

When the engine speed increases, the exhaust gas discharge speed and turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. Increasing the pressure and density of the air can burn more fuel. By increasing the amount of fuel and adjusting the engine speed accordingly, the output power of the engine can be increased.

The reason why the supercharger makes abnormal noise is:

(1) The turbocharger is damaged and there is abnormal noise caused by metal friction;

(2) Air leakage in the intake and exhaust pipes, or cracks in the intercooler, or leakage of pressurized gas;

(3) The membrane of the bypass valve is broken and gas leaks;

(4) There are burrs or bumps on the inner wall of the housing, and the abnormal sound generated by high-speed airflow flows through it;

(5) Contamination in the diffuser section of the turbocharger;

(6) The surface of the impeller is dirty and the air flow is not smooth. A supercharger is an air compressor that increases air intake by compressing air. It uses the inertial impulse of exhaust gas discharged from the engine to propel the turbine inside the turbine chamber. The turbine in turn drives a coaxial impeller that compresses the air sent by the air filter pipe and pressurizes it into the cylinder.
