The throttle by wire adjusts the throttle opening and fuel injection according to the depth of the accelerator pedal. The electronic control will adjust the fuel injection quantity according to the engine speed.

For example, if you drive 60 kilometers, put in fifth gear and step on the accelerator to the end. If the throttle is controlled by wire, the engine will be in a potential rod state. Fuel injection is the largest, but the speed is still not up, wasting gasoline. However, electronics will only give the appropriate fuel injection amount according to the engine speed at that time to protect the engine and save fuel.

To put it simply: the electronic throttle has a sensor, and the computer can determine the throttle size according to the position of the accelerator pedal, and provide the corresponding current to the throttle motor to control the throttle opening. The throttle and throttle are connected by a flexible cord instead of the traditional cable control.
