What is the effect of increasing electric turbocharging?

The cost of general electric turbine is 1/20 of that of exhaust turbine. And is easy to install on various vehicles. Although the power of electric turbocharging system is not as good as that of exhaust gas turbine, the principle is the same. Exhaust gas turbine is to improve the power of the engine through the principle of step by step, which is also used by electric turbine. It's just different in shape, structure and control mode. As long as the proportion of mixed gas entering the engine changes (improving volumetric efficiency), the power of the engine can be improved. When the engine speed is low (starting state); The throttle valve is fully open-the electric turbine starts to work-and the turbine speed reaches the maximum. Because the engine speed is low, the fuel quantity will not increase rapidly. At this time, excessive air enters the engine-the mixture concentration becomes thinner (16: 1). Because the electric turbine is a modified product, the engine computer ECU doesn't know when to work, and the fuel injection lags behind at this time-the engine is frustrated. Adjust the signal of the vacuum pressure sensor in time, increase the fuel injection (at this time, the engine will inject extra fuel according to the speed parameters), and at the same time cooperate with the throttle (throttle position sensor) to achieve the standard mixture ratio.
