What should I do if the turbine pressure relief valve squeaks too loudly?

The turbine pressure relief valve is too loud and squeaks. The reason is: 1. When driving a turbocharged car, when stepping on the accelerator to accelerate, the accelerator will open and the engine will send out "huh?" As the speed increases. The engine emits high-temperature and high-pressure waste gas energy to drive the waste gas turbine to rotate; 2. When the rotational speed of the turbocharger is reached (that is, the rotational speed of the turbine is above 65,438+million revolutions per minute), the turbocharger compresses the surrounding air, increases the air intake of the engine, and improves the dynamic performance of the engine; 3. When we collect oil, the throttle opening decreases rapidly until it is in the closed idle state, that is, the engine does not need air intake or the air flow in the intake pipe will be blocked at the throttle; 4. But at this moment, the turbocharger has not stopped working! Because the inertial turbocharger is still maintained at 65438+ million revolutions per minute.
