What's the matter with car turbocharging?

Turbocharger is a kind of air compressor. Without changing the engine structure, it uses the waste kinetic energy discharged by the engine to pressurize the air, so as to increase the air intake of the engine and improve the engine power.

Specifically:

1, the turbine in the turbine chamber is driven by the inertia impulse of the exhaust gas discharged by the engine,

2. The turbine drives the coaxial impeller,

3. The impeller squeezes the air sent by the air cleaner tube to pressurize it into the cylinder.

In the whole process, when the engine speed increases, the exhaust gas discharge speed and turbine speed will also increase accordingly, and the impeller will compress more air into the cylinder. With the increase of air pressure and density, more fuel can be burned, and the output power of the engine can be increased by increasing the fuel quantity and adjusting the engine speed accordingly. ?
