What is the principle of electronic throttle control?

The control principle of the electronic throttle is that the electronic throttle changes the throttle opening according to the situation that the driver steps on the pedal, and the vehicle using the electronic throttle can control the fuel consumption more accurately. The upper part of the throttle valve is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Electronic throttle is an important control part of automobile engine, which consists of engine, speed sensor and throttle. Electronic throttle can accurately control the throttle opening, which can not only improve fuel economy and reduce emissions, but also obtain satisfactory handling performance. On the other hand, it can realize the integration of idle speed control, cruise control and vehicle stability control, and simplify the control system structure.
