Is the opening of cable throttle valve 7% normal?

7% opening of cable throttle valve is normal. The throttle opening is also the opening angle of the engine throttle, which can be changed by the driver through the accelerator pedal. When the car is idling, the normal throttle opening is generally around 3-5%, and it is generally not more than 8% at the beginning, but it also varies with different models. If the opening value is a bit large, it is generally not that the throttle is broken, and it is estimated that the throttle is too dirty. Just wipe the throttle clean.

Throttle principle

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.
