Electronic throttle valves are integrated with actuators, position sensors, throttle valves, etc. The ECU controls the opening of the PWM signal, and the opening of the throttle valve controls the intake volume of the mixture, thus changing the output power of the engine. Electronic throttle according to the ECU instructions, there are three working states: 1, when the engine speed is lower than the idle speed target value, the ECU idle speed control, that is, control the throttle opening position, keep the engine speed near the idle speed target value. 2, when the engine speed exceeds the maximum rated speed, the ECU limits the throttle opening position, that is, the higher the speed, the smaller the throttle opening position. 3. When the engine speed is between idle speed and maximum rated speed, the throttle opening position is directly controlled by the pedal, that is, the throttle opening position changes synchronously with the pedal position.
