Why are there two cables on the accelerator?

One is called throttle cable, and the force exerted on it is directly transmitted to the throttle return spring. The other is called oil return pipeline, which has two main purposes: one is to prevent the throttle line from sticking to the rubber on the surface due to aging or icing, and then it will be dangerous. The principle is that it accepts 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.

Throttle is a controllable valve, which is used to control air to enter the engine. After entering the intake pipe, it is mixed with gasoline (different models of cars have different design mixing parts) to become combustible mixture, which participates in combustion and does work. Four-stroke gasoline engines are generally like this. Throttle is the most important component in EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.
