What is the function of the automobile cable throttle?

The function of the cable accelerator of the Pacific automobile network is to directly control the opening of the throttle plate through the steel wire. When stepping on the accelerator pedal, the accelerator opens at a corresponding angle, which can directly and quickly control the accelerator.

The difference between electronic throttle and cable throttle: the electronic throttle is a cable or pull rod that replaces the cable throttle with a wire. Simply put, the electronic throttle is automatically controlled, while the cable throttle is mechanically driven.

Original title: How to distinguish between cable throttle and electronic throttle?

First of all, we have a preliminary understanding of the cable throttle and electronic throttle from the appearance.

Throttle pulling is to control the throttle opening of the engine with a steel cable, thus controlling air intake and fuel injection.

As can be seen from the figure below, the throttle is connected by cable.

As the name implies, the electronic throttle controls the opening of the throttle through the electronic unit, so as to achieve the purpose of controlling the air intake and fuel injection.

We can't see the cable from the picture below, but we can see the small motor that controls the throttle opening.

Secondly, from the control principle.

The cable accelerator is that one end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator through fulcrum and guide. When you press the accelerator pedal, the throttle will open at a corresponding angle. Therefore, the throttle can be controlled more directly and quickly, and the throttle response is faster and more timely.

The electronic throttle transmits the pedal position information to the ECU of the driving computer through the pedal position sensor, and then the ECU sends an instruction to the electronic throttle, and then the throttle motor performs the opening action of the throttle. During the whole process, the response was a bit slow. Therefore, there will be a delay in the emergency refueling of the electronic throttle.
