Does the turbocharger installed in the intake pipe affect the car?

What the landlord said should be the so-called "electronic turbocharging" mentioned on the Internet recently, which is really useless. car home and other major websites have detailed comments on it. First of all, another name for automobile turbocharger is exhaust gas turbine, which is installed on one side of exhaust manifold. The exhaust gas from the engine pushes the turbine and supplies fresh air to the cylinder, thus increasing the cylinder pressure and power.

In addition, the structure of installing an electronic turbine on the intake side is similar to that of the secondary intake. Installing this device between the air flow meter and the intake manifold seems to increase the intake air volume, but first of all, the current EFI vehicles read the intake air volume through ECU, and simultaneously correct the fuel injection volume to achieve a suitable air-fuel ratio. The air intake of electronic turbine is not calculated by air flow meter, so the fuel injection of computer has not changed. It may play a small role at low speed, but it is not as good as the original natural inhalation power at high engine speed. This is because the exhaust gas turbine usually works at tens of thousands or even hundreds of thousands of revolutions per minute, while the electronic turbine and the secondary intake work are driven by electricity, and the speed is similar to that of a computer fan, only a few thousand revolutions per minute, which is a resistance in the case of high engine speed. This is a stunt made by the manufacturer, which is not credible.
