Are electric superchargers and electronic turbines the same thing?

With the popularity of turbocharged engines, people have learned more about turbocharged engines. For example, turbocharging technology can make small displacement engines have stronger power output. However, because the rotation of the turbine depends on the exhaust gas of the engine, the turbine can't work when the engine speed is low and the exhaust gas displacement is small, which is what we often call turbine lag.

In fact, the problem of turbine lag was discovered long ago, and the solution is not without it. For example, when the exhaust gas of the engine is insufficient, it is just that this method of turbocharging and turbocharging is too expensive and unrealistic for mass production; Another method is to optimize turbine size, blade material and blade angle. Although the problem of turbine lag can not be completely solved, it can at least reduce the turbine lag time.

In addition to the methods mentioned above, it is said that there are two other ways to solve the problem of turbo lag, namely, adding an electric supercharger and an electronic turbine.

Many friends can't tell these two things apart. After all, their names are too similar. However, in terms of function, they are very different. Let's talk about the electric supercharger first. This kind of thing is sold online, and it can also be seen in some modification shops and roadside express shops. Its popularity among car owners is still a bit high.

This kind of thing can only be said that publicity is in place, but the actual effect is basically zero. There is a simple reason. Its power comes from the automobile battery, and the voltage of 12V makes it difficult for the turbine to rotate quickly, and its rotation speed is far from the pressure requirement of air compression. Naturally, nothing can solve the turbo lag problem of turbocharged engines. This is a stunt.

Electronic turbines mostly appear in 48V hybrid vehicles. Driving with 48V voltage can make it compress air, thus increasing the intake pressure, so that the vehicle equipped with turbocharged engine can start quickly without reacting after stepping on the accelerator for 2 seconds. In a sense, the popularity of electronic turbines depends on the popularity of 48V hybrid vehicles.

In traditional fuel vehicles, the power supply is 12V. If you want to increase the voltage, you need a complicated mechanism to realize it, which will increase the cost, increase the risk of failure and increase the overall volume of the engine. In a word, the disadvantages outweigh the advantages. On the 48V hybrid car, there is no such problem. Anyway, it is a hybrid, which is nothing more than letting the 48V battery pack "keep a job" again.

To sum up, the electric supercharger is unreliable, and the electronic turbine is worth seeing!
