How can there be two wires connected to the accelerator in the automatic gear of a car? What lines are they? !

We call it the throttle cable, and the force exerted on it is directly transmitted to the throttle return spring. The other is called the oil return pipeline, which has two main functions: one is to prevent the accelerator cable from sticking to the rubber on the surface due to aging or icing, and then it will be dangerous ~ The principle is that it receives the force of the accelerator spring and then transmits it to the accelerator pedal, so this force is a cycle. Another function is to prevent the throttle bracket, which greatly affects the driver's perception of the throttle in the race ~
