What's the difference between the electronic throttle in the car and the ordinary mechanical throttle? What is the working principle?

Difference: Compared with the two throttle bodies, the electronic throttle has higher technology content and more economical fuel consumption control. At present, most models adopt electronic throttle, which is also a trend of future automobile development. However, there will be some delay when the electronic throttle accelerates.

Working principle: Electronic control throttle system, working principle: The pedaling amount of the accelerator pedal is transmitted to the accelerator pedal position sensor of the accelerator lever, and the engine electronic control unit sends an instruction to drive the throttle through the motor to control the throttle opening. ?

It is detected by the accelerator pedal position sensor with built-in accelerator lever. Throttle opening is matched with various control signals such as EFI, ECT and VSC. The engine ECU determines the appropriate throttle opening, and then the throttle actuator opens or closes the throttle. ?

The throttle opening is fed back to the engine ECU through the throttle position sensor. The accelerator pedal position sensor and the accelerator position sensor are equipped with main and auxiliary systems, so when the system fails, it can still maintain the function of continuous monitoring to ensure safe operation.
