What is the effect of electric turbocharger?

The exhaust gas turbine rotates passively, and the exhaust gas replacement pressure is very high. The maximum speed of the exhaust gas turbine can reach 65438+ million revolutions. The electronic turbine is driven by 12V DC of the battery. Although we don't have instruments to test the actual speed of this electronic turbine, let's think about it for a while. How fast can such a DC motor driven by 12V power supply be? I think it will last more than 6000 revolutions. The sound of turning it on is not much different from that of the fan on the CPU. (It's plastic, especially rough ...)

As can be seen from the above figure, under the same gear, the performance of the electronic turbine is a little faster than that of the original factory, but this advantage is really meager. Also, for a modified part with a price close to 1000 yuan, can this accelerated increase be ignored?

The improvement of power by electronic turbine is definitely not worthy of this modification cost! It's nothing like exhaust gas turbocharging. It's totally different.

From the measured results, in the two fuel consumption tests that basically overlap before and after the modification, the fuel consumption after adding the electronic turbine is half a liter higher than that of the original car, which is not a small amount for a car with a displacement of 1.3L, and only a negligible 0.3 second 100 km acceleration is paid for this half liter of gasoline. Is it worth it?

Why does fuel consumption increase? Because the function of the electronic turbine is to increase the air intake, and this device is installed in front of the throttle, the data read by the air flowmeter is larger than that designed by the original factory, and this signal will be transmitted to the ECU for reference by other systems. One of them is that the fuel injection quantity will also increase with the increase of air intake, so in theory, the fuel consumption will also increase when stepping on the same throttle.
