What is the fan-like accessory installed on the intake pipe behind the throttle?

Turbocharger. According to the inquiry of Pacific Auto, the turbocharger is actually an air compressor, which increases the air intake by compressing air. It uses the inertia impulse of the exhaust gas discharged by the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which pressurizes the air sent by the air cleaner pipeline and sends it to the cylinder.
