Does the electronic throttle have no idle motor?

The electronic throttle has an idle motor.

There is a motor in the electronic throttle, but the idle speed and refueling are determined by controlling the opening of ECU.

Electronic throttle is an important control part of automobile engine. The basic structure of the electronic throttle system consists of the following parts: 1, engine 2, speed sensor 3, throttle position sensor 4, throttle actuator 5, throttle 6, throttle pedal position sensor 7, speed sensor 8, transmission 9, throttle pedal 10 and throttle electronic control unit (ECU).

In order to improve the safety, power, ride comfort and economy of automobiles and reduce emission pollution, various electronic throttles with good control characteristics and their corresponding electronic control systems have been introduced by the world's major automobile manufacturers, and electronic throttle control systems (ETCS) have been formed. The electronic throttle control system can accurately control the throttle opening, which can not only improve fuel economy and reduce emissions, but also make the system respond quickly and 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 structure of the control system.
