Basic Introduction to Electronic Throttle

Electronic throttle is an important control part of automobile engine. It is composed of engine, speed sensor and throttle. The throttle opening can be accurately controlled by using electronic throttle control system.

The basic structure of electronic throttle system consists of the following parts: 1. engine; 2. speed sensor; 3. throttle position sensor; 4. throttle actuator; 5. throttle; 6. accelerator pedal position sensor; 7. speed sensor; 8. transmission; 9. accelerator pedal; 10.throttle electronic control unit (ECU).

In order to improve the safety, power, stability and economy of automobiles and reduce emission pollution, major automobile manufacturers in the world have introduced various electronic throttles with good control characteristics and corresponding electronic control systems to form electronic throttle control system (ETCS). By using electronic throttle control system, throttle opening can be accurately controlled, which not only improves fuel economy and reduces emissions, but also achieves rapid response and satisfactory control performance. On the other hand, it can realize the integration of idle speed control, cruise control and vehicle stability control, and simplifies the control system structure.
