Inertial turbocharger itself has no power, how to boost it?

The intake compression of a four-stroke engine does work and exhausts, with one revolution and two revolutions.

That is to say, at 1200 rpm, the single cylinder sucks 10 times per second. When the speed is 600 rpm, the single cylinder inhales 5 times per second. Poor air intake means that the engine consumes a small amount of power to maintain and improve the speed of this turbine.

In the first intake stroke, the engine consumes more work than before to accelerate the turbine and suck in air at the same time. In the last three strokes, the engine does not intake air, and the turbine pressurizes the air in the intake pipe through inertial rotation, while the turbine speed decreases.

In the second intake stroke, the air with relatively high pressure in the intake pipe enters the cylinder, and at the same time, new air enters the accelerating turbine, which consumes a part of power. But the pressure of air entering the cylinder is a little higher than that of natural inhalation. Because natural inhalation is definitely negative pressure.

If the engine speed is 1200 rpm and the turbine accelerates 1/40 seconds (depending on the amount of air in the air pipe, it is better to double the displacement), the turbine decelerates and supercharges the air in the air pipe for 3/40 seconds. This is a single cylinder, four cylinders multiplied by four.

This is the supercharging principle of inertia turbine. The intake resistance increases, which has a little supercharging effect.

This supercharging effect will increase the power of the engine a little, but God knows whether it can save fuel.

The biggest problem is that if iron chips fall from that turbine, the engine will be finished.

At the same time, the inertial turbine has an optimal speed range. Beyond this range, the turbine has almost no supercharging effect, only consumes suction power and does not increase any pressure. The engine speed span is very large, generally 600 ~ 5000 rpm. Turbine adapts to high speed, but the effect of low speed is poor. Adapt to low speed and high speed difference. At present, many good engines are generally supercharged by machinery at low speed and turbocharged at high speed. The pitches of the two turbines are different, which adapts to the speed of different intervals. This inertial turbine has only one pitch, and the high-speed end is invalid.

Generally, I don't feel anything when I report to the high speed, which is the reason.

It's not pseudoscience, but the effect is not obvious.
